Hi All,
I have an LG Optimus G E970 on the AT&T network, all stock. I recently dropped it and, of course, the digitizer glass cracked. The screen still worked just fine, and I could turn it on and off without a problem but no touch at all. As I was trying to shut it down without using any buttons by just holding the power button, it started acting strangely. I would turn it off (screen timeout) by just pressing on the power button, but when I would wake it up (by again pressing the power button) the cap. buttons on the bottom would light up, but the screen would stay dark. I chalked it up to the digitizer being messed up.
I have since installed a new screen/digitizer assembly, and it works great when I turn on the phone. However, as soon as the screen goes to sleep, I get the same problem - cap. buttons light up, but the screen stays black. All the buttons are working, as I can here them clicking, and I can turn up the volume, etc, I just can't get the screen itself to light up.
Has anyone run across this problem, or have any suggestions? I've already, reluctantly, tried a hard reset, which did not solve the problem, as well as any other little fixes that I found in this and other forums. I'm thinking it's a software issue of some sort, since the screen and everything work great when the phone is on, but I don't really know. I wanted to see is there were any answers out here before I tried rooting and installing a new ROM, which might be problematic anyways if the screen doesn't come back on.
TIA,
George G.

Hi everyone.
I dropped my phone today, and the screen broke.
The phone still seems to work properly, but the classic signs of a broken LCD are present: purple screen with many many lines and nothing legible.
I have ordered a replacement screen already, but I cannot get the phone to shut down and stay turned off.
Since the screen is broken internally, it does not respond to my touch.
I can hold down the power button for 15 seconds but that does a reset, and the phone automatically turns back on.
Is there anyway to keep the phone off other than by draining the battery completely?
I need to keep it powered down so that I can disassemble it safely.
Any ideas?
Thanks!

I don't know of any way, but as long as you are careful while disassembling you should be fine. You should be able to pry the screen out enough that you can disconnect the battery before disconnecting the screen. I doubt disconnecting the screen with the phone on would damage anything anyway. I believe people do this iPhone screens all the time to test them.
Hey, new guy here.
So about 2 weeks ago my EVO 4g LTE's power button started acting crazy. I would have to push it really really hard to make it turn on. Sadly it has gotten to where now it just doesn't turn the phone on at all. I have since downloaded an app from the market to use the volume keys to turn it on from sleep mode, but cannot turn it off without being able to turn it back on (the app only supports waking the phone up). I've taken it apart, cleaned it and still no luck. No matter how hard I press it, it just won't turn on. The button also no longer gives that slight "click" when pressing it.
I ordered a new button, took it apart, replaced the button and still nothing. It still doesn't even click. I'm wondering what the part underneath the power button is called. Would that be the power button flex cable. I'm speaking of the part the button actually touches to produce the power on/power off effect and the mild click it gives when pressed.
I bought the phone used and when I took it apart, it appeared to be tampered with at this same location. It looked like this section had a black coating on it where the power button would touch but had been rubbed/scrapped off, showing copper.
If anyone knows what this part is please let me know so I can order/replace it.
Thanks in advance
So about 3 weeks ago, I dropped my HTC so now I have a large crack running down the middle of the screen. However I haven't had any other problems up until last night. The ringtone volume turns itself up without me even touching the phone every now and then and once it does that, the power button stops working. But it does work again once the screen is switched off, meaning I can turn in on but not off. The power button functions fine until the volume button acts up the first time after restart.
I factory reset my phone thinking it may have had something to do with the software but the problem came back within the hour when all the updates started rolling in. Once it did, i booted it into safemode and the problem seemed to stop but I don't know what's causing it. Could it be an actual bug in an update or is the damage to the screen simply too much for the phone itself? Has anyone ever dealt with a problem like this? Any help will be appreciated as I know it's expensive to fix these things and I don't want to go to the shop to get it fixed only for the problem to come back as it's software related.
[AT&T] V10 Screens won't power on but phone vibrates once when power button pushed
BONE STOCK ROM. One day my V10 screens were unresponsive. The mini screen was updating time correctly but wasn't responsive to touch, and the power button would not wake the main screen.
I removed the battery for 30 seconds then replaced, pressed power button. I had one short vibration then nothing. Neither screen comes alive. Removal of battery and replacement followed by pressing power button always gets a single vibration like it's powering up, but screen never comes alive.
Has this happened to anyone else? I am also wondering if in repair, someone could somehow access my data... I have sensitive information but the system is security locked with screen pattern.

Sounds like your LCD and digitizer has went out need to get it replaced . No they can not access your phone all they will do is replace the LCD digitizer and power it on to see if it comes on once it does there job is done . Replacing or repairing repairing screen will not erase anything because all your info is saved on the motherboard
The title almost says it all,
If I leave my phone running for a while, even at idle, my Galaxy sII's screen sometimes goes black and the phone doesn't respond if I press volume buttons or the power/home button, the screen does not light up and it is as if the phone is dead, but it is running because my computer recognizes it upon plugging in and I can transfer files.
If I had music playing while the problem happened, the music continues playing but the screen is black and the buttons are unresponsive. It seems that the phone works but after a while of usage, it just turns black and I have to take off the battery to get it to reboot and work fine again.
It was running on android 4.2 if I remember as it was a secondhand phone, possibly rooted and experimented around by the previous owner. I tried flashing it to CM12 but the problem still persists.
Has anyone ever ran into this problem? What might be the cause and cure?

If it's doing that even in other ROMs then I'd say it's a hardware issue, maybe proximity sensor, under normal circumstances the screen stays black and won't wake when you press the power button, when the proximity sensor detects something close or when the sensor is covered it keeps the screen off, it could be faulty and acting as if it detects something even though it isn't there.
Or it could be the battery maybe?
