Update in Post #19 (Listen to me now and believe me later).

Problem:

Sporadic heat and lag issues

Theory:

Flash is the culprit (or a big part of it)

Rationale:

Things that normally make an Android device run hotter are N64 & PSX game emulators, Flash, and wifi tethering. I have played both emulators and some sustained time with wifi tethering, but none have yet made the DX2 run very warm (this is very nice).

It almost seems like there is an issue with Flash, since it does seem to be what instigates both the warmer temps and the lag issues. My gTablet has Froyo and 10.3 Flash, but does not have the heat or lag issues. Something appears needing tweaked within the DX2 firmware.

If I stay away from Flash, I do not appear to have the problems. Even when using Flash, the heat and lag issues do not appear to happen consistently, but are sporadic. I do notice that Netflix does not have any heat or lag inducing issues. Runs quite nice. Seems like Flash sometimes hangs in the background after using, even though it does not show in the task manager.

I am determined to keep the DX2, since luv the build, display, radio reception, sound quality (sans the skips), form factor, wifi tethering, dual core for emulators and battery life.

The jump from the Incredible is truly as big as the jump from the G1 to the Incredible. Pretty big jump, to say the least.

Still, VZW had better update with fixes ASAP and not wait for Gingerbread, since GB apparently does not like dual cores in the current version.

 

I use Flash on demand only. Seems Flash is a key issue and like Russian roulette if it happens or not.

 

The point is when using Flash, it sometimes seems to lock onto resources (even after exiting Flash) and that may be why people are apparently having sporadic heat and lag issues.

Try restarting the DX2 and not use Flash at all, plus make sure Flash is set to "off" or "on demand". I have not had any lag or heat problems since leaving Flash alone. Flash seems to sometimes work fine, but then other times it can go nuts with the DX2's resources (hence the lag and heat).

All the usual suspects do not get the device very warm: N64 & PSX emulators, higher def vids and wifi tether. This kind of stuff usually makes a lot of devices run hotter, but not the DX2.

It seems the issues are either Flash in general, or 10.3. Whatever the case, I hope it is fixed soon in the firmware.

 

I sent a formal note suggesting this may be one of the issues, but does not hurt for all people to be vocal to VZW. Nothing will get done if a lot of folks are complacent and assume things will get done. Not referring to people here, but a general statement.

 

Assuming Flash is the issue, all you have to do is set Flash in all browsers as OFF or ON DEMAND. No need to freeze it or uninstall.

I see what some of you mean that some games run very warm. Riptide is sweet, but fancy graphics come at a price. The non Tegra games do not seem to do this. Pinball seems okay for Tegra games.

 

I think bug is Java fed.

 

After two days of testing, I can about confirm that the root to a lot of the lag and heat issues is Flash.

1. To test this, restart the device and do not mess with Flash & make sure set to off or on demand in any browser you use. Then see if you have as many lag or heat issues.

2. The DX2 gets up well over 110 degrees when running Flash and sometimes "hangs" in the background (you can tell, since the CPU % will sometimes still be high, even after exiting the Flash content).

I do not recall these issues until installing 10.3, but need to find 10.1 (I think that is what was on it?) to confirm if either Flash itself, or 10.3 is the issue.

The Droid 1 and Incredible do not get this hot and neither does the core temp of the Tegra 2 gTablet.

Seems some updating needs to take place- pronto, buy Motorola and VZW.


Added: Anybody have 10.1 and 10.2 links?

 

One thing is for absolute certain. Flash 10.3 SUCKS THE LIFE out of the DX2. I tested the Revolution for ninety minutes today and compared to the DX2 and TB (mainly the DX2).

I could not help but notice that vids I tested on Dailymotion.com performed MUCH better on the Revolution. Smooth as butta and herky jerky on the DX2 (all vids were in HQ mode). One example is a CES 2011 preview via IGN that is linked on the Dailymotion site. No comparison.

One interesting point is both devices ran at 103 degrees during playback, but the DX2 seemed hotter- due to the metal back cover. None the less, it was a jerky mess on the DX2 and smooth on the Revolution.

I downgraded the DX2 from 10.3 to Flash 10.210.2.155.67 (only one I could find in short time). The good news: Performance is much better and on par with the Revolution. The bad news: I get random but common device resets now when playing Flash.

I like Flash on my device, but Flash does NOT appear to like the DX2. This is not a Tegra 2/ Froyo issue, since my gTablet plays Flash sites very fine with no heat spikes or resets.

 

The picture quality is not as good using Skyfire and less sites work with it. Besides, Flash works great on the Revolution and the gTablet, so proves Flash can behave. The gTablet proves without a doubt that Froyo + Tegra 2 = great Flash performance and no heat spikes. Something is wrong in the firmware to be causing these issues on the DX2.

Be nice to get Gingerbread and see if the issues are fixed with it (MP3 pops too).
