First question - what is the LTEvo? It's the popular nickname for the HTC EVO 4G LTE, as invented on this forum in our pre-release days. :)

Isn't it a little unprofessional to call it by a nickname in a FAQ? Not really. It's actually fun - it's pronounced EL TEvo. Rolls right off the tongue, so Early insisted on using it a lot in this FAQ. :D Anyway, some people hate it being called that - and to those, Early apologizes.


Without further ado -

Tell me about the phone!


Q: Does it really have a kickstand?

A: Yes - the kickstand is back. It will support the phone in either landscape side, so you can charge it while on the kickstand. Some sites show it being used in portrait, but HTC is not recommending that.


Q: Is it really only dual core?

A: Yes, but those two cores are lions - the new Krait architecture from Qualcomm, far more powerful than the A9 cores appearing in other high-end phones. Two of these really are pretty close to four of the other.


Q: What about power?

A: Expect excellence. http://androidforums.com/htc-evo-4g-lte/533941-important-new-technologies-s4-graphics-power.html


Q: What's all this about HD Voice?

A: It's part of the new Sprint Network Vision update and phone support is required - the LTEvo has it. Full details below the Hide button -

About HD Voice and Bluetooth

HD Voice == phone <-> network <-> phone

There's a wide range of audio quality in Bluetooth headsets and audio codecs supported for Bluetooth.

The LTEvo supports the highest Bluetooth standard and you can get an HTC dongle that plugs into your car's auxiliary port and get CD-quality music from your phone to your car stereo for the LTEvo (that doesn't apply to earlier Evos).

So, I think it all comes down to how much you want to spend on a Bluetooth rig for your headsets.

~~~~~~~

About sound quality

I use a _wired_ fabric-sheathed monobud from the Sprint store, available for $15 - it doesn't have a model id that I can give.

When I used that on my Evo, everyone - and I mean everyone - kept remarking that they'd never heard me, or possibly anyone, sound so clear on a phone call, including land lines, ever. They didn't say that about my 3vo and I tried a lot of headsets.

Short version - something in the audio circuit of Evo was done extremely right, and they haven't repeated it on other phones (and it took a particular headset to get it).

So, I think that the real point of HD Voice is to get everyone to that standard, but it will still take quality components in the phone and however you use it, naked, BT, or wired.

~~~~~~~

About audio sampling and HD Voice

The sampling method used for a cell phone is called a vocoder.

You could change the 3vo's vocoder to improve its voice quality and I definitely did that.

The older phones supported the EVRC vocoder, and some of us upgraded our settings to EVRC-B.

HD Voice is using the EVRC-WB vocoder.

Details at - Mobile Wireless HD Voice Today and VoLTE in the Future | SONLTE

Hope this helps! :)


Q: Does the handset have a speaker phone feature?

A: Yes, it does. One reviewer claimed it was even better than the original Evo, and far surpassed the Evo 3D.


Q: How about HDMI support?

A: Yes, please see details under the Accessories section of this FAQ.


Q: Does it have Gorilla Glass? What kind?

A: Yes, please see details under the Accessories section of this FAQ, under screen protectors.


(under construction - more coming soon!! :))



Q: Any protection for the camera lens?

A: Yes!

The camera lens is behind glass that is inset from the removable outer bezel. Flat surfaces should be safe.

4G


Q: Will the HTC Evo 4G LTE operate on Sprint's current Wimax network like the Evo 4G and Evo 3D do?

A: No, The Evo 4G LTE will be operating on Sprint's up and coming LTE network.

Even though they are both forms of 4G networks, they operate on different hardware architectures, technologies, and radio frequencies and are thus not compatible with eachother. Wimax will continue to operate in portions of the metropolitan US that already have existing Wimax coverage for the next year or two. In other words existing Wimax compatible handsets will continue to have the same 4G function. LTE is Sprint's future network vision.

Will this handset be able to use WiMAX 4G in addition to LTE? [short answer: different tech]


Q: When will 4G LTE be coming to my town?

A: Sprint has a rollout scheduled they are following entitled Network Vision. Here is their vanity site for 4G as of this posting -

4G LTE is coming to Sprint in 2012

Try checking in with this site frequently for the best Network Vision info:

Network, Network Vision/LTE Deployment - Sprint 4G Rollout Updates


Q: Any current maps on that?

A: Sprint LTE May 2012 Schedule Maps - Sprint 4G Rollout Updates


Q: Will Network Vision be bringing my phone faster 3G speeds or other benefits as well as LTE?

A: For most subscribers, yes. Some of you are plagued by bad 3G towers, most are plagued by an aging internal network at Sprint - all is being upgraded and 3G performance will be greatly improved for many. Some accounts say to expect between 2 and 3 Mbps downloads, but an expectation of between 1 and 2 Mbps download speeds - consistently! - is what we'll see with Network Vision.

Should we worry about the 800mhz/1900mhz debacle?


Q: Does the Evo 4G LTE have a SIM Card slot?

A: No it does not have a SIM slot. There may be a SIM onboard but it is embedded in the phone and un-accessible to the user.


Q: If the Evo 4G LTE has a SIM card in it somewhere does that mean it will be a World Phone and can function overseas?

A: No, The Evo 4G LTE is not a world phone.


Q: Can the Evo 4G LTE roam on AT&T and Verizon&#8217;s LTE networks?

A: No it cannot Roam on other 4G Networks. As of right now each carrier&#8217;s LTE network is operating on a different frequency utilizing different hardware.

Will Sprint and Verizon phones roam on the others LTE (Answer: no, different frequencies)

MicroSD Card and Storage


Q: Does the Evo 4G LTE support MicroSD Cards?

A: Yes, it has a MicroSD card slot and ALSO has on board memory storage. This is a unique feature and great benefit to this handset.


Q: What capacity/size MicroSD card will work with the Evo 4G LTE?

A: HTC specifies that any MicroSD card up to 32 GB will work with the Evo 4G LTE, however, like many other phones, 64 GB cards have been confirmed working.

What size microsd card will work in this device?


Q: Will the Evo 4G LTE Come with a MicroSD card installed in the MicroSD card slot?

A: No, the Phone will NOT be shipping with a MicroSD card


Q: The Evo 4G LTE says it has 16GB's of internal storage. Will I actually be able to use ALL 16GB for my personal storage?

A: No, A portion of the 16GB will be allocated for the operating System, system files, settings, pre-installed content, and more.

Internal Memory Allocations:


  • 9.93GB - Phone Storage (used like a MicroSD/Mass Storage card)
  • 2.09GB - Internal Storage (Applications)
  • ~3GB or Remaining portion of 16GB after formatting - operating system and phone firmware

Repeating info already stated, as a convenient wrap-up post -

App space on -

Evo 4G - 427 MB

Evo 3D - 1.15 GB (about double an Evo)

LTEvo - 2.09 GB (about double a 3vo, quadruple an Evo)

The 9~10 GB of user space will show up on your favorite file browser (EStrongs, Astro) under the /sdcard folder (even though it's not really a physical sd card).

The rest of the 16 GB is used by the operating system and necessary included apps (phone dialer for example), radio firmware and the bootloader.

Again - nothing new here, just a wrap-up post. Hope it helps! :)

On the 9 to 10 GB of phone storage, what can be placed there? Can apps, music and pictures be placed there?

Exactly what can be placed on your Evo 3D's sd card. Music, pictures, vids, some app data.

Some apps can moved there with apps2sd or the equivalent built-in.

Many apps moved to the sd card will continue to store data into the 2GB apps area.

Here's how a phone is laid out (very simplified version) in terms of partitions. They're just like partitions (or logical drives, if you will) on a PC hard disk. Instead of drive letters, they get folder names -


  • /boot
    • kernel goes here, it's not big
  • /system
    • Android, Sense, and included apps (when you open the box) go here
  • /data
    • your apps go here (this area is pretty rich, it's the 2 GB part of the LTEvo)
  • /sdcard
    • a physical sd card on most phones, but actually a reserved space of 9~10 GB from the 16 GB storage on the LTEvo
    • Android always expects to see this folder/area
    • acts just like the sd card on an Evo or 3vo
  • /cache
    • the operating system cache - ignore this, it doesn't concern you as a user as far as managing things go
  • various hidden areas
    • bootloader, radio firmware, etc - ignore this, it doesn't concern you as a user as far as managing things go
  • /sdcard/ext_sd or /sdcard2
    • if you install an actual sd card into the LTEvo, it will be accessed with either one of these names - both will exist, both are shortcut to the physical, removable sd card

Q: What?!?!? Doesn't it have Gorilla Glass?

A: Yes. http://androidforums.com/htc-evo-4g-lte/547629-gorilla-glass-version-used-lte-4g.html

That still won't save you from sand!!! http://androidforums.com/htc-one-x/535826-warning-one-x-screen-not-scratch-proof.html


Q: Will the Evo 4G LTE include Beats Audio software enhancements?

A: Yes it will feature Beats Audio enhancements when any headset is plugged in as part of the audio equalizer options.


Q: If it has Beats Audio Enhancements does that mean it will ship with Beats Audio headphones as well?

A: No, the phone will not be coming with Beats Audio headphones, in an effort to keep the cost down on the total price of the phone.

HTC executive says it plans to drop Beats Audio headphones from some smartphone boxes


Q: Will the Evo 4G LTE Battery be removable like it was in the Evo 4G and Evo 3D?

A: No, the Battery will not be user accessible.

Since the phone has a uni-body design made of 'space age aluminum' there is no access port built in for removing the battery unit. HTC opted for a design change to slim down the total form factor of the phone. We get a slightly larger capacity battery from HTC but it is non-removable now.


Q: Does the Evo 4G LTE have an HDMI output port?

A: It does not feature a typical HDMI output, it does however have a specialized micro USB port with MHL technology (Mobile High Definition Link).

MHL allows high definition video output through the Micro USB port. A growing number of new TV&#8217;s are shipping with an MHL input on them. If you don&#8217;t have a compatible TV, there are special cables/ adapters made that convert Micro USB MHL to HDMI, allowing you to connect your phone to your HDTV.


Q: Where's a good place to get an MHL to HDMI adapter?

A: Monoprice.com


Q: Won't my original Evo 4G micro HDMI cable work?

A: Sorry, no - not at all.


Q: Is there an alternative to MHL -> HDMI?

A: Yes! You can still use media sharing (using a DLNA-capable TV) to share stored photos and some videos.

You could also try the new HTC MediaLinkHD for wireless streaming to a HDTV


Q: I have the Media Link HD all hooked up, now how do I get my content to display on the external monitor?

A: You only have to remember one simple on screen gesture. You take 3 fingers and place them on the lower part of the screen and swipe towards the top of the screen.


Q: Does it support CD audio quality in a car?

A: Yes, this answer under construction.

Sense 4.0


Q: What is Sense 4.0?

A: Sense is the graphical overlay and added programs and convenience functions provided by HTC to augment the Android operating system. Sense 4.0 is a lighter version of this software than previously provided because many features are now included in Ice Cream Sandwich (aka ICS aka Android 4.0) and because Sense users wanted a lighter interface.


Q: Can I take a screen shot of my phones current screen?

A: Yes, Press and hold the power button then the Home key. The shot will be saved to the gallery like any picture would be.


Q: Can I back up my text messages?

A: Yes, new In Sense 4.0 you can back up text messages within the messaging application. Tap menu in messages -> then back up messages and then name the file. They will be sent to your storage.


Q: What size wallpaper does the Evo 4G LTE use?

A: The Screen has a resolution of 720 x 1280, however you will want to use a picture with a resolution of 1440 x 1280 if you want your image to cover the span of all your homescreens. As you swipe your home screens left to right your wallpaper will pan along with you.

720p (HD) Wallpapers for our phones..


Q: I don&#8217;t like Sense, is there any way I can change to a different style? What is a launcher?

A: What 3rd Party Launcher to use with ICS?

NFC


Q: What is NFC?

A: Near field communication - Wikipedia, the free encyclopedia

Think of NFC as similar to Bluetooth - two compatible devices use its radio standard to communicate. Unlike Bluetooth, NFC is limited to about 12" distance between devices.

Q: Will the Evo 4G LTE have NFC capabilities?

A: Yes it will feature NFC (Near Field Communication) on board and integrated into the hardware and software. Beam is HTC's onboard NFC client in the phone for exchanging content with compatible NFC Devices. Apps -> Settings-> Wireless and Networks -> More -> Beam on/off

Q: Does it include Google Wallet?

A: Google Wallet, a convenient way to pay for things using your phone via NFC instead of using your plastic credit card, is included with the LTEvo.

Q: Are there other uses for NFC?

A: Yes! Using "NFC tags" (think - stickers or keychain fobs), you can for example create tags for your home, car or office - when you scan one with your phone, you can have the phone automagically change its configuration for whatever your needs or desires are.

NicksGarage said:
Another question is, do you need to buy preformatted NFC tags for the EVOLTE?

SVDO - talk and surf at the same time on 3G


Q: What is SVDO?

A: SVDO is a way to get simultaneous voice and data over a CDMA 3G connection only. The HTC Thunderbolt on Verizon features it as one example. It's not at all common.

Remember the old AT&T commercials where they tooted their iPhone because you could be on a call and on the web at the same time? It's essentially the same thing for CDMA, you are able to talk over a CDMA network and be online at the same time.


Q: Does the Evo 4G LTE have SVDO?

A: Yes. Here's proof!

Thanks for the awesome FAQ. I really appreciate the work. However, just wanted to show you these links in regards to SVDO.

SVDO on the HTC EVO 4G LTE - YouTube

and

xda-developers - View Single Post - EVO LTE supports SVDO!


Q: How trustworthy is that info?

A: Very. In addition to couragedragon squaring this away for our forum, I was immediately curious if this would apply to production units and here's that confirmation -

Sgt. Slaughter, member here, XDA mod, friend, poet, and all around good guy, got with AJ at s4gru.com and confirmed via Brian at Anandtech that SVDO is a production feature of the LTEvo.

That is confirmed on the old Sprint network.

For those unfamiliar, SVDO means that you can talk and surf the web at the same time, using nothing more than a 3G connection. No 4G or wifi required.

Here is what he said at HTC EVO 4G LTE - Sprint 4G Rollout Updates - Page 29:


Sgt. Slaughter said:
Our friend AJ sent this to me today as I had been asking him about SVDO as some had mentioned it would only work after NV was deployed and over 1x advanced...

...I asked Brian Klug at AnandTech if the production model EVO 4G LTE supports SVDO. He confirmed that it does. So, the FCC OET certification docs are correct. The info and rumors to the contrary are wrong. Furthermore, Brian is in the Tucson/Yuma market, which has no Network Vision deployment yet. So, bar none, SVDO is fully functional with Sprint's legacy CDMA1X 1900 + EV-DO 1900 network. Brian even supplied a YouTube video....

By the way, according to Inside Sprint Now -

This is nothing new to most early-adopters of the HTC EVO 4G LTE, however there are some details released below that may be of interest – such as it&#8217;s obviously not guaranteed, and it does require certain conditions to work properly.


  • Sprint 4G LTE phones can acheive Simultaneous Voice and Data (SVD) when connected to a WiFi router.
  • They may also achieve SVD when connected to Sprint&#8217;s LTE or CDMA networks.

  • Sprint 4G LTE phone customers may not see a consistent SVD experience on Sprint&#8217;s networks based on numerous conditions.
  • SVD should not be guaranteed to our external customers.
  • SVDO is possible on Sprint&#8217;s LTE phones/handsets, without assistance of LTE or WiFi, utilizing 1x and DO.
  • Works only in optimal network conditions.
  • Experience not consistent with SVDO; in weaker coverage, voice will take sole priority.

  • SVD can be achieved with either LTE or WiFi coverage.
  • CDMA + LTE, or CDMA + WiFi should be the primary combinations to achieve simultaneous voice and data, as with previous phones/handsets.
  • If utilizing SVDO, the experience will vary, however, if in optimal conditions data speed will be consistent with EvDO speeds.


Back to top

(Under the Show button below are remarks I made previously. If you have doubts that the Evo 4G LTE can do SVDO, I may have played a hand in that. I hereby retract those statements and apologize for the confusion.)
No. According to the blogosphere the answer is yes, and there are rampant claims that FCC test documents show that.

I have two problems with that:

  • First, the modem built in to the LTEvo does not support SVDO.
  • Second, the FCC test documents don't show SVDO test results.


What it will support when Sprint is ready is SVLTE - simultaneous voice with data over LTE, Dan Hesse confirmed this at a recent financial community review (needs link here).




According to Qualcomm, here's the modem set built-in to the S4 SoC -

Snapdragon S4 Processor MSM8960 chipset includes the industry&#8217;s only complete platform that integrates all of the world&#8217;s leading 2G, 3G and 4G mobile broadband modem technologies on a single chip. This new integrated multimode modem is based on an advanced, programmable architecture that is performance, size and power optimized for the fastest combination of modems available for:
  • LTE FDD/TDD (Cat3)
  • 3G (DC-HSPA+ Cat 24)
  • EV-DO Rev. B
  • 1x Advanced
  • TD-SCDMA
  • GSM/GPRS/EDGE
(and)

For LTE handsets, the 8960 modem enables UMTS/GSM voice and LTE data (CSFB), as well as simultaneous CDMA voice with LTE data (SVLTE).

(and)

Mobile broadband technologies are growing increasingly complex in their implementation. LTE is currently being implemented in over 40 different radio frequency bands throughout the world. To complement its wide range of modem standards supported, Qualcomm has designed the Snapdragon S4 Processor MSM8960 CHIPSET platform to address all commonly-used frequencies (from 700&#8211;2600 MHz) and bandwidths up to 20 MHz, allowing its customers to address any mobile network opportunity whether the sim- plest single frequency implementation to the most extensive multi-frequency global mode, whether 4G, 3G or 2G.

(and)

Industry&#8217;s first fully integrated 3G/4G world/multimode LTE Modem: Supports all of the world&#8217;s leading 2G, 3G and 4G LTE standards. It also includes integrated support for multiple satellite position networks (GPS and GLONASS) as well as short range radios via Bluetooth, WiFi, FM and NFC.
From Qualcomm

PDF download required, so I'll include it here - View attachment QU_SnapdragonS4_White_Paper_FNL_Rev6.pdf



How about the FCC part?

Referring to page 6 of 45 of this document - https://apps.fcc.gov/eas/GetApplicationAttachment.html?id=1653714

It says:

6990296452_6c776b3476_z.jpg


No where does that indicate SVDO.

Hey Early, I have an update for the Sense 4.0 section. Today I figured out that there are two different ways to take screen shots. I think one method originates from ICS, and the other from Sense. Also, the methods have some key differences.

Here's what I've got so far, copied and pasted from the Screen Scene thread:

A screen shot may be taken by either:
1) Sense 4.0 Shot - Holding down the power button, then tapping the home button. Using this option:
- - the shots are saved into the 'Camera Shots' folder
- - you can only take a shot of the screen as it sits
- - the photo is taken instantly
- - there is a small popup saying that "screenshot saved to camera shots"
2) ICS Shot - Pressing and holding both (at the same time) the power button and the volume down button (for about 1.5 secs). Using this option:
- - the shots are saved into their own 'Screenshots' folder
- - a screenshot can be taken, while at the same time utilizing/demonstrating some other function on the screen with another finger (e.g. dropping down the notification bar, moving an icon, holding open a 3rd party folder widget, etc).
- - again, it takes about 1.5 secs to take the shot.
- - a notification is added to the notification bar that lets you view the shot when clicked.

I have downloaded my Outlook contacts and music along with some photos. The phone asked for an sd card so I inserted it. I can access the music and the photos and files I kept on it. I cannot figure out how to access and use the contacts. This may be a dumb question to you all. But I am brand new to Android phones. And so far this phone is blowing my mind... hope I get to know it well soon. I really want to get my contacts and favorites set up soon. There is really a lot to learn with this phone. Any suggestions are appreciated. : )

Well this was certainly bologna. Speakerphone on the EVO4G far surpasses the LTE.:(

^^^^^^^^^^^^^^ x2
The speaker phone and the volume of the ringer were better on the original Evo than the LTEvo. in my opinion as well

Weird variations. Mine is excellent, easily compares to the Evo speaker, a little less bass, but plenty of volume. Very clear more than a room away. :thinking:


I put my OG and my LTEvo right next to each other and played the same song through both. OG was louder at 100% & 90% volume, LTEvo only overtook it at 80%. It is loud enough for me for most purposes, but my OG was barely loud enough to listen to on stock speaker while in the shower, LTEvo I can't hear half the time.
