[Q] Backlight issues - G2 and Desire Z Q&A, Help & Troubleshooting

I'm having an odd problem. When my G2 is sleeping (screen off, not charging) the backlight intermittently turns on and off. I'm currently running a CM7 nightly (#21) but have attempted to troubleshoot this by flashing several (non-CM7) ROMs, and the problem remains.
I've been unable to see anything in a logcat dump showing the screen or backlight activity.
Another symptom is that pressing any of the "hard" buttons (besides power) cause the backlight to momentarily activate, then turn off.
It behaves this way in any mode--airplane, wifi on/off, bluetooth on/off.
Otherwise everything else seems to function normally--as long as the screen is supposed to be on, it's great. Sitting on the table or nightstand flashing the backlight all night, no so much.
Anyone else had this problem, or is it time to start hunting for a "donor" device?

[Q] phone freezes after screen off

After lots of flashing it has caused my phone to freeze with the screen off after about a minute (So I cannot turn it on, to reopen the phone I have to hold the power button to force reset) , the notification led stays in the some state as when I turn the screen off. the strange thing is that if I am listening to Music , this does not happen.
tested multiple android versions of android , kernels, roms and even using a stock rom
factory resetting. etc.
nothing works. the only thing I havent tried is pit flashing.
Any ideas guys?
help would be much appreciated.

[Q] Screen randomly turns off after KitKat update (Note2)

I was browsing through the forum to see if anyone has a similar problem, but this doesn't appear to be the case.
Since I updated my Note 2 (UAE version) to 4.3, my screen keeps turning off completely randomly (even when in the cradle). It just goes blank. Now - the phone doesn't go to sleep and I know that because if I play video, it still keeps playing (I hear the audio). When the screen goes off, I then need to push power button to turn off the screen and turn it on. If the video is playing, pushing the power button will of course lock the screen, so I actually first need to push home button to get out of the video, then power button to turn off the screen and then power button again to turn it on.
Am I explaining this well? So, the problem is not that the phone goes to standby, the problem is that the screen stops functioning and i need to push power button to put it into standby and then back from standby.
It is completely random - I can sometime work on the phone for hour and nothing will happen, and sometime it will happen after few minutes. It doesn't matter what I am doing, whether playing video, browsing web, checking email etc.
Anyone with a similar problem? Anyone, class, anyone? Bueller? Bueller?

Hi, got a SGH-T889 with the back lit led screen keep go out once in deep sleep (happen over night or after not using for a period of time). This can happen during charging or not charging, the phone is cold or warm, its environment warm or cold.

-Any button or combination of buttons pressed will wake the phone.
-Pull battery and pop it right back in, phone turn on but screen and backlit buttons lit up for a micro of second and turned off. The phone still function.
-Pull battery and leave it out for a minute, pop battery back in.
-Phone wake and function normally until the next time it happen.
After problem, I've notice I've got some new files which I don't know what are they but they're seem to relate to the issue. See attached.
I'm running sammobile stock 4.3 ROM: T889UVCMK7
Phone is rooted, have teamwin touch recovery v2.7.0.1
Does anyone experience this? and hopefully have a solution.

[Q] Weird problem with ambient mode

Hi guys, I bought a new zenwatch and am experiencing a weird issue. Occasionally, when the watch is in ambient mode, it is not responsive to touch. I turned off wrist gestures to wake up the device, and need to tap it to wake up. Sometimes I tap it and nothing happens at all, it stays in ambient mode. Pressing the power button at the back will wake up the device and it will function normally. It is just slightly annoying to have to press the power button which is on the back a few times a day. Any input to why this might be happening is appreciated.
I have the same problem, but sadly no solution. I've had the watch since Jan and it only recently started doing it, last month or so
At least its good to know I'm not the only one, probably a software bug.
Mine does that occasionally. I find that rotating it back and forth a couple of times (even though Tilt to Wake is switched off) before touching the screen clears it.
Mine did that just a little while ago. I do still have tilt to wake turned on, though, and after waking once that way, it's back to responding to taps now.
Also, selecting a different watchface from the phone seems to clear it.
Pretty sure it has something do to with the latest update. Maybe they are using more aggressive power saving settings on the cpu governor, making it take longer to ramp up clock speed and be responsive.
