Just bought a second hand GS3 from ebay, the screen had a small crack but otherwise was meant to be OK. I am finding that the sound will work fine after a restart for as long as I use the device but then, after it has gone to sleep (screen off for five seconds) all sound will stop working.
I've tried clean wipes/formats etc. and also checked all relevant settings I could find (including turn off all sound in accessibility; what an odd option).
I've tried two ROMs and three kernels.
I've tried searching google and xda for hours but haven't found anything that wasn't related to the headphone port; this affects both speaker and headphone, although when the headphone is in and the sound has died I can hear some strange static noises when it's meant to play sound, could be interference or a clue.
I've dismantled the phone and inspected for damage, nothing obvious. While dismantled I tried applying pressure to the speaker flex cable and various other IC's to no effect.
It really seems like a software glitch since it only happens when the device goes to sleep;
You can turn the screen off and unlock within 3 seconds and it will be OK.
If you wait 5 seconds with the screen off - boom, no sound.
Any ideas? Is there some deep idle sleep setting that kicks in after 3 seconds I can disable or some way to log audio errors or... something?
Thanks

I have encountered some strange issues with Galaxy R during the past few days. The first issue is when I plug in my headphones when the phone is idle (i.e. screen off) the menu key often fails to wake it up. Only the power button wakes it up. Sometimes, it wakes up but after a greater than normal delay This happens only when earbuds are inserted when screen is off.
Secondly, sometimes my touch screen and capacitive buttons loose their sensitivity for a couple of seconds (say about 10 seconds) and then come back to normal. The menu and power button works fine but the touch controls are lost.
Has any of you encountered the same? Please comment. Thank you!
Mine Galaxy R doesn't have any of this. I'm on 2.3.4 and you? I think its a defect. And where you wrote this:

I think that is normal because you cant unlock the phone by using the back or menu button.
Device: HTC One M8 running Liquid Smooth from may 13th.
This is rather odd - All day, my phone was working just fine. As I was listening to some music (through the speaker... or should i say speakers boomsoundhighfive:highfive, I pushed the power button to unlock the phone to text somebody, except all I could see was the music app (apollo) in the background with a dialogue saying that android system UI has stopped. Every time I hit "ok", it popped right back up. I'm assuming that that was because it was trying to restart, and it just kept crashing.
A bit later, it was still doing the same thing when all of a sudden I could no longer turn on the screen. However, my music is still playing, and I can control the volume with the vol buttons. The only other thing I can do is double tap the screen to get a bit of hepatic feedback from double tap to wake. Also, the low battery notification LED is now flashing, as it was at fairly low battery when this started (around 30, it's been about 45 minutes since this started).
I can't reboot through ADB as usb debugging isn't on, and I tried holding down the power button for about a minute with no luck.
Anybody got any advice? My current plan is to wait for it to die and hope it reboot normally... Otherwise I might boot straight into recovery and restore a nandroid...
Alright, sorry for creating this thread - it died, I plugged it in and turned it on. It appears to be completely working. Anybody know why this would happen? It seems a bit odd.
Hi,
I have a MTCD-KGL for over an year now. The only issue I have with the device is that after power up, sometimes, not always it freezes after start.
Precisely:
- This happens once every 2-3 boots
- This happens regardless if it does a real power up or wakes after a sleep
- The freeze usually happens 10-15 seconds after startup, however sometimes it might happen immediately or take up to 3-5 mins to freeze
- When I set it up to sleep instead of shut down (after car power off) and the radio app has been turned on before shutting down, after power up of the car and device it would usually start the radio app again and turn on the sound and freeze only after this. Same is true for my navi app (Here to go) i.e. it would start the navi app after boot and then freeze. Sometimes I'm able to make a click or two before it freezes
- If it makes cold start (i.e. had been shut down) then it shows the launcher UI
- When it's frozen I could reset it via the reset button, however I can't power it off via the power button
- When it's frozen, the touch screen doesn't respond at all, while hardware buttons only make beeping sound. However nothing changes, no matter what button I press. Turning the volume knob makes multiple beeps, however the volume doesn't change. Pressing back, home or anything else also makes beep but no effect
- Shifting to reverse doesn't show the revers comer either
I have updated to numerous different firmwares, both KGL and others as well numerous KGL MCUs, however with all combinations the problem persists.
The device is not rooted yet, I could do it if it would be from any help.
Any idea? I don't know what might be causing this freeze, which is keeping the last snapshot on the screen and buttons beep, radio plays, but nothing else happens. Apparently it's not software problem, because updates of the firmware and the mcu would have solved it. So it should be a hardware one. Any idea where to look at?
Thanks and regards

Its an older unit and I would tend to think that your system is running out of memory.
I tried doing a System Update on mine but the dang head unit can't find the .img file in any slot nor usb port.
Hi,
This problem occurred about a week ago.
When I hold my volume up or down a few seconds to adjust the volume, suddenly the volume bar maxes out or hit the bottom and gets stuck there.
If I try to adjust it on-screen (without the buttons) like when it gets stuck at the maximum volume it jumps to the maximum volume again. (Same thing goes for the opposite).
Now About the power button.
It just doesn't work sometimes. Like it won't turn on my phone or turn it on.
BTW I changed my ROM to AOSP extended for about 2 or 3 weeks ago but this problem just happened as I mentioned before a week ago.
What should I do to fix this?
Thx in advance!
Your buttons are probably broken, go see a technician..
Hi, I started having the strangest issue 2 days ago. Phone model is Samsung Galaxy A50.
I have been unable to unlock my phone once I pressed the lock button or if it went to sleep (screen off).
The only way out of the issue is to restart it by pressing volume down and power for 5 seconds. I put the screen timeout to 10mins (which is the maximum). But no long term solution. Whenever the screen turns dark it stays dark. If a call comes in, the phone vibrates (or ring) but any interaction with the phone is impossible. If I play music, the music continues once the screen is off. The sound can be turned up or down, but it's the only thing that can be done.
While the screen is on, changing the volume via the buttons affects the actual volume of the music, but there is no UI indication that the volume changes, no popup nothing.
So all physical buttons are working correctly.
I have trie "reset parameters", I have tried "reset all data" (backed up everything through Smart Switch). It doesn't change a thing. The phone is reset (still on android 11 though, although I bought it on android 10...) but the issue remains.
Now something very interesting :
Just now, I setup Phone Link for windows 10, so that I am able to see and answer texts and phone calls while at the office. Which works, it sort of defeats the purpose of a "cellular" phone but well...
HOWEVER : while my phone is connected to my desktop through Phone Link. I can lock and unlock at will, change volume and see the UI pop up (via the windows interface or directly on the phone, same behaviour) It's basically fixed. I thought it was fixed for good, so I disconnected my phone from Phone Link. The screen went black as before and there was nothing I could do except reconnect it via Windows 10 (then it immediately starts behaving as usual again...).
My guess is it's definitely software. I just don't understand why a factory reset didn't do the trick...
I wanted to try and reset through the bootloader, but I never managed to effectively get into the bootloader (through volume up and power while the phone is off).
I do not recall making any updates or installing anything just before these symptoms occured. I did install a firmware update that was available after these symptoms started but to no avail
Has anybody seen this before ? Thanks in advance
