Issues multitasking (white/black screen, etc) on the HTC EVO 4G LTESupport

    I can't believe that an app designed to be run in the background (a service app), like System Panel would be killed. these should NEVER be killed automatically by the OS. Are people also reporting that their music players (especially non-Sense players) are quitting in the middle of other multitasking activity??

    Yep, the minproc value is set a little too high - all sorts of apps bailing have been the subject of complaints here in and the One forums (where Sense 4 lives, iow). We had an HTC press release covered by Phandroid a few weeks back saying, thanks for the feedback but it's working as we intended.

    Merged threads as this has turned into the multitasking discussion, maybe a few tidbits in posts above, including a tip for rooted users.

    Still curious if switching launchers works around the problem. Can't see how it would... but surely we have users out there running 3rd party launchers that could give us some data points?

    App bailing is controlled by system parameters (there are several that you can see running some of the various monitoring apps).

    If you get less of a system load on memory for any reason, including some 3rd party launcher requiring less ram than Rosie (the Sense launcher), I can see how that would alleviate the issue.

    I installed Apex to try it out, and after a reboot I do see more ram available.

    Stock, I would have ~170MB free.

    With Apex, it jumped to ~210MB.

    HTC Weather also takes up a lot of ram. About 50MB. I switched to BeWeather, and this one uses 25MB.

    I tried switching between Facebook and Instagram, and it does seem to work better.

    It's crazy but true. You should've seen my disappointment and dread when I noticed that SystemPanel was constantly getting killed and that even Sense itself was frequently reloading -- I could go to AndroidForums, open up several threads as new tabs and then watch as my brand new phone started to freak out (I would get the "toast" notifications multiple times about how SystemPanel App was starting the monitoring service -- it was struggling to come back after dying).

    When I was using Sense as a launcher, it was consuming ~200-250 MB of RAM, but with Apex, I'm at ~60-80 MB. I'm a little astounded too because I would just imagine regardless of how much RAM the launcher is taking up, that other apps would get kicked before High Priority ones, but it's really not clear what is going on under the hood. At any rate, using a new launcher has increased my happiness notably.

    When I have time this weekend, I'll film a few videos of the memory management in action to help diagnose (and to get HTC off their butts with this whole "working as intended" garbage).

    I actually experienced it freeze up a bit today when I was on a call, a call was coming in, and it was trying to sync to my email. Only lasted a couple of seconds.

    Really glad to hear that reducing mem footprint relieves the issue somewhat. This is near dealbreaker for me, since I know I would not be able to tolerate the malfunction for very long.

    If this is indeed working as designed, the designer(s) should be summarily terminated. This is unacceptable. If this must be there to support Sense on ICS, then my logical conclusion is that Sense should be scrapped.

    Then again, I'd prolly prefer the Sense Camera app over any AOSP app... can't win.

    For those unfamiliar, some of the ram goes to a ramdisk used by Android, and some goes to support the display and memory mapped i/o.

    On a 3vo, of 1 GB RAM, about 830 MB was available to the os and user.

    On the LTEvo, that number is 680 MB.

    It appears that quite a few processes attach to the Sense launcher, that's why it's footprint seems so high.

    I can confirm that using Nova Launcher made my experience much better today. My Sense was starting to reload and show me a "Loading..." screen every time I hit the Home key.

    Thanks to everyone who has contributed to this thread. It's helped me keep my sanity :)

    I've had Sense reload once so far, but I am not web browsing much, that tended to trigger it on my 3vo.

    I was doing a good job avoiding problems until I started surfing on the browser. It didn't take much. 2 different sites on 2 tabs, and my System Panel disappeared. Exited the browser, and System Panel came back. Interestingly, I didn't notice exactly when SP went missing, but Tasker sent me a notification saying memory was low. That was when I noticed it was gone. Time to give the customer launcher a try.

    Strange but I am not experiencing any of this but it sounds like some of you are trying to run/do to many things at the same time. I know Apple has limits like this in place too and why it "sort of" multitasks the way it does.

    I did have a problem with Tango hanging the other day and trying to use voice in SMS but it turned out to be another app EVA not releasing the microphone.

    Android has always been this way, it was simply harder to force the condition before.

    It seems to be the combination of less available ram and a higher threshold setting for minimum free memory.

    It's going to affect some people not at all and others quite a bit because it does depend on how much the user is doing at once as well as the size of the tasks involved.

    Coming from the Evo 3D, I'd guesstimate that, all else being equal, we've lost the ability to load the equivalent of a few extra web pages.

    Well I'm not sure where I am going wrong here. I read that HTC multi-tasking link that says not to keep too many apps open. However, I can't keep a single task open.

    I try and back out of everything I am not going to use anymore. I even checked running apps and the only ones on there are the ones that always run like "maps". However, when I play the game 'Cartoon Wars' I can't leave the game for anything. The second I press the home button or the task button to check a text or change a song, it restarts Cartoon Wars... almost every single time. There is almost never a time I go back to the game to have it sitting the way I left it. Mind you, I only leave the game for a few seconds tops and I never "back out" of it, always use the home or task button...

    Needless to say, not being able to do anything but play my game out of fear of losing my progress is REALLY frustrating.

    this new sense/ics and how it wants to much RAM space... is a big deal for me.
    i know, i can use custom ROMs that might help this.. or go full ICS, but then i am also loosing a lot of what i like about evos. I like sense and what it gives me.
    so..it actually has me looking at the S3.

    but the radios history in past samsungs have me on the fence.
    I am waiting to hear more from sprint users review of the new S3.. GPS performance.. after release.

    they never make it easy!!

    So... you don't want to load any custom roms because you like Sense so much and your solution is to get a Samsung?
  18. dan330

    dan330 Well-Known Member

    I am saying.. Since I am looking at going custom ROM without Sense.. Then I should look at S3, which has 2Gb of RAM too..

    Or, if you like Sense, try viper's rom - debloated Sense with the minimum free memory value set to something less agressive, some say that does the trick.

    Or the SGS3 - that's shaping up to be a nice phone, too.

    I'm going to stick with Sense, debloat it, tinker it, and then decide if I want to try anything more radical.

    Please let us know if/when you come up with something that works. I am still waiting on my LTE, but discussions of its camera ("all marketing, it's a blur-fest with grotesquely over-sharpened edges") and multitasking ("there's only 600MB ram free due to gfx mapping, and sense takes 500 of that") leave me absolutely horrified. Since I got mine secondhand and am still waiting for it to arrive, I don't think I can return it. I was so excited for this phone... is it really that bad compared to the SGS3?

    Looks like Samsung is more than hype this time. The RAM makes the multitasking issues disappear, and the camera samples look incredible compared to the LTE, both zoomed out and zoomed all the way in (though I haven't seen comparisons with turned down HTC's ridiculous sharpness/contrast/saturation settings yet). Sure, I'd lose a kickstand, better screen (more accurate colors and resolution), Sense (I've gotten quite accustomed to it), and HTC's build quality (Though scratched by sand?)...

    What to do?

    EarlyMon The PearlyMon Moderator

    Nah, the camera is really great, you may want to dial back saturation under settings (depending on the lighting, etc). Check out the images thread here, nothing blurry there (except maybe my quick and dirty drive by snap, lol), and Sense does not take 500 MB of the 680 available.

    I will going with the Chameleon rom, to get my buttons my way, and then applying any of viper's mods by hand, then debloating.

    I was fully prepared to return this to go with the SGS3 if I was in any way unhappy, but the unhappies I have are too minor and too easily addressed.

    The screen is simply amazing. Calls are crystal clear. Impromptu snaps of the family are absolutely fabulous.

    The multitasking woes can be dealt with.

    And all screens will scratch easily with the right sand - the active ingredient in sandpaper and sandblasters, very little can stand against sand. ;)

    If you haven't already, you should take a look at
    http://androidforums.com/htc-evo-4g-lte/554045-user-reviews-htc-evo-4g-lte-first-impressions.html

    Great opinions from great people.


    I've tested a few games and have found no lag.
    I do get that pesky Menu button on the screen though.
    But this is the app dev's problem and will probably show up on other ICS phones too. I didn't see it playing Temple Run.

    After browsing with like 6 tabs opened on the default browser with "View Desktop Site" enabled, I do sometimes get Sense to reload. Web browsing consuming a good amount of RAM is to be expected (even on the PC).

    The LTEvo is an excellent phone with great build quality and camera. I am a Sense fan. Don't let all the opinions and gripes of the phone get you down. I dislike TouchWiz but like the 2 GB of RAM on the SG3. But when I fiddle with my LTEvo, I can't help but fall in love with it again.

    That's odd.

    You aren't using a task killer, are you?

    Can you - reboot your phone with fastboot off (settings, power), open a text message, tap home, then open your messaging app again, let us know what happens?

    Thanks for the wonderfully encouraging response! With a custom ROM, debloat, memfree tweaked defaults, and eventually zram-enabled kernels -- especially with multitasking increasingly looking like a conditional bug in some handsets under certain conditions -- I'm quite heartened.

    On further inspection, it seems all of the LTE's shortcomings can be fixed in software (save for battery replacement, which is a non-issue for me; in fact, I can't count the number of times I dropped a phone mid-call just to have the battery pop out, sometimes corrupting data). Even the internal storage 'shortcoming' can be mitigated with my 32 (and soon, 64/128GB) microSD[H/X]C card.

    Samsung's shortcomings compared to the LTE (flimsier plastic design, gimmicky TouchWiz UI, lack of kickstand or shutter button, hideous PenTile + blue tint + 300%LCD power white pixels) aren't nearly so easily overcome, however. When you get down to it, a phone is made up of its hardware and software, and in both respects the LTE wins hands-down (save for the Sense multitasking glitch which I'm confident will be fixed/worked around soon enough).

    In sum, to compensate for the few GS3 specs it falls short of, the LTE simply needs software tweak(s) and an SD card. However, to compete with the LTE where the GS3 falls short, the Sammy would need a whole new screen technology devoid of PenTile, inaccurate blue-tinted colors, or black-creep; an entirely new metallic/solid outer chassis; a glue-on kickstand (or one integrated in some bulky case); a hardwired camera button glued onto the side; and a driver-level UI overhaul (either Sense or "senseless," anything not taking a "touch-whizz" on the user experience). See, it's harder for the SGS3 to live up to its pitfalls with respect to the LTE than vice versa.

    At the end of the day, the LTE as a multimedia phone seems the better (and sturdier) choice with a more accurate screen -- both in terms of color and effective resolution, where its 1050x590 effective dimensions take 300% of LCD's power to render white regions of equivalent size and relative luminance (that's organic diode tech for ya) -- white remains the vast majority of the internet, by the way, especially for mobile sites.

    The SGS3, thanks to PenTile, has an effective pixel density nearly identical to last generation's Evo 3D (259 vs 256ppi). This is not cool, especially since I can make out the 3D's pixels easily enough when zoomed out. Compare that to the LTE's screen with an incredible 312ppi. That's close to retina display (326ppi) level, folks, spread out over 4.7 inches, with accurate colors to boot.

    Coupled with Samsung's shoddy history with GPS and radios (despite great whitepaper tech specs in the chipset) and patchy customer service (repairs, pushing updates, etc) since the Galaxy S (1)...not a Rosie picture. True, neither of these points are yet substantiated in regards to the S3, but history just may be worth more than a grain of salt. HTC certainly isn't flawless in either arena itself, but at the very least this isn't a point in Sammy's favor.

    I doubt the numbers matter, but fwiw, the LTEvo is 312 ppi. ;)
