My A3 doesn't "wake up" from stand-by.
If I reset it keeping pressed power up button, it correctly reboots, I can see all boot process and it correctly reachs the starting home page.
If I keep touching screen, open apps, navigate from various menu all works fine. But when I leave it without pressing any button/screen for 10/15 sec (display power off delay) the screen correctly goes black, but there's no way to wake up it again although it seems working. The A3 "under" works because plugging to AC Adapter beeps the sound of charging in progress, PC (Kies or SmartSwitch) detect it correctly; only the screen remains black.
I already tried to wipe and even reflashed last firware with Odin but with no luck.
Is there anything else that I can try (except send it to repair center...)?
Thanks in adv

P.S. When I call It from another phone, it rings but the LCD remains black and doesn't respond clicking vol +, vol - and home buttons
P.S. 2 Thinks become "funny": Home button, vol + & vol - don't work at all. Power button powers off display, but long pressing it, doesn't pop up power off/reboot menu. Softkeys don't work.
Sounds like SoD. Try installing the app "Wake Lock" and choose the PARTIAL_WAKE_LOCK option.

Hi all,
My new Nexus 7 (2013 model) arrived today, and it seems that it can only boot up through the bootloader menu, i.e. the power button does not work properly. When plugged in, the battery charging icon does appear for a few seconds before disappearing.
The problem is that holding down the power button does not turn the device on. Holding down volume down+power button works correctly and shows the bootloader menu, and from there selecting "Start" is the only way to actually boot the device. When plugged in to a power source (outlet or computer), holding down the power button causes the battery charging icon to appear, disappear, and reappear constantly. Holding down the power button when unplugged shows no response on the screen, even after holding down for a full minute. Once the device is booted, the power button works perfectly for locking, unlocking, and showing the power off menu.
I already tried doing a factory reset, which did not help at all. Is there anything I can do to fix this problem?
Your best bet is to ask in your device's forum section as this section is for the 2012 version.

My phone's battery died so i plugged it in and when i did, the bootlogo appeared for around 5 seconds then disappeared. This repeated for hours. I tried pressing Power+down for 10 seconds and this resulted in the screen turning off and the led flashing red. I tried again and this resulted in the bootlogo issue. After several hours of charging, results are no different. Phone is completely unresponsive when not plugged in. Please help.
UPDATE: Managed to boot into recovery and reflashed my rom (SOKP D801), but no change. Is this rom broken and will a different rom fix the issue? Also, i can't seem to enter recovery again. (Note: rom is discontinued by developer and website is gone.)
UPDATE 2: Phone randomly started working again for no apparent reason. To avoid the original issue, should I switch roms?
did you tried hard reset?...
If your phone is on, turn it off.
Press and hold the Volume Down and Volume Up buttons, and then press and hold the Power button at the same time until the phone turns on. You'll see the word "Start" with an arrow around it.
Press the Volume Down button twice to highlight "Recovery mode."
Press the Power button to start Recovery mode. You'll see an image of an Android robot with a red exclamation mark and the words "No command."
While holding the Power button, tap the Volume Up button once.
Use the volume buttons to scroll to "wipe data/factory reset" and press the Power button to select it.
Scroll down to "Yes - erase all user data" and press the Power button to select it.
Note: If your phone becomes unresponsive at any point during these steps, you can restart it by holding down the Power button for several seconds.
The button combination resulted in a hardware control menu, not recovery
Guys I was yesterday turned off the phone, now turns and reaches the black background with logo of Samsung Galaxy S4, then restarts, will not let me enter recovery mode, and if I enter download mode, gives me the option of pressing button increase or decrease volume and pressing any of these resets and returns to the above.

What can I do?
Your power button may be stuck.
when pressed, it feels normal

It just "feels" normal.
Try tapping it on a hard surface for a while..not too hard tapping though..
It should be fine. Happens with many here
could it be because the place you battery latches only
I just remove the phone to see if the buttons are locked, and there were none in this condition
I believe there are 3 connections on the motherboard for the power button. Do you have a multimeter to see if the power button circuits are constantly open or closed?
I opened it and pulled the internal button on and off and was constantly rebooting, I took a technical service and changed the internal button now works well; )

Fast fast try to return it before Trump wins . He will build the wall you know... Jk...
For my opinion LCD has to be changed. Due drop or in your pocked from high pressure i think its gone ...
Since as you said phone is working you can take pictures or receive calls but screen is always black.
Can you see its black color or screen isn't turning at all.
Sent from my ONEPLUS A3003 using XDA-Developers mobile app
Mine started with green stripes allover the screen and few days later - "black screen"
Samsung change the whole unit.
But if lcd doesnt work so, it wont recognize when i press the screen, can it?
Anyone with this problem

S7 Edge BSoD Extra Info. needed
Hi,
Phone: I have a Samsung Galaxy S7 Edge SM-G935FD
I was using my phone to send a txt (and at the same time I think I was receiving a text or call because the menu and back touch buttons were lit up) and all of a sudden the phone crashed as I tried to finish my text but the touch wasnt responding, then the backlight turned of like it does if the phone is not being used. But the strange thing was that the menu and back touch buttons stayed lit up (Solid).
I tried many methods to restart the phone:
Power button + volume down (FAILED)
Power button + volume up (FAILED)
Power button + volume down + Home (FAILED)
Power button + volume up + Home (FAILED)
So I thought I'll let the battery die and then recharge and hopefully the phone would automatically restart like normal, however the phone does not show sign of charging now.
So I tried to connect to the PC but it wasn't being recognized however when I press and hold the power button a sound of detecting a device sounds and then when I take my finger off the sound of detaching occurs. But I couldn't see anything happening, until I went into device manager, under "Other Devices" , "Exynos8890" appears which I know is the chipset.
This is as much as I know of the problem. How do I solve thins problem without trying to factory reset the phone and lose all my data?
PS: I didn't backup my photos (My baby children only copies) or Notes in NotePad, which has some very important info.
