Hello everyone please help request - G2 Q&A, Help & Troubleshooting

Recently there is a problem with the device. The power button does not turn the device on and off, sometimes vibrating but the screen does not wake up even when connected to the power supply.
Double tapping does not respond. Sometimes the screen will turn on for a second and turn off.
Sometimes everything looks right.
When this happened, the device warmed up around the power switch.
So I replaced the lighting component and now the problem continues random without the device warming up.
Does anyone have any idea what the problem might be and how to solve it?
Thanks so much everyone.

bluetooth keeps phone awake - how can I stop this ?

When my touch dual is connected to my bluetooth headset, it causes the screen to be constantly on (rather than going to sleep).
This causes problems for me because when it is in my pocket, things are accidentally touched on the screen.
How can I stop the phone from staying "awake" with the screen on when it is connected to a bluetooth headset ?
Thanks
press the power button for it to shut down the screen ?
Thanks but I should have mentioned that when I press the power button, it turns off then just turns itself straight back on again.
unknown problem, but i know niki will turn on inside magnetic field. try if you're not holding anything magnetic close to the screen?
niki seems to think you slide it open when magnets come close to the device.
Did you ever fix this?
My AcerDX900 with winmo6.1 does this too and it's killing batterytime....

Overzealous slide mechanism

Hey guys,
I've recently flashed the latest AMP (Wm 6.1) onto my G4 and i've noticed an annoying problem.
I don't know if it's the ROM or the fact that i've not used the device in a while, but it seems the slightest nudge on the screen will turn the device on and light up the backlight.
This is really annoying and will kill my battery quickly. Is there any app or registry tweak that can disable the slide mechanism from activating the power i.e. if the power is off, opening the slide will not power the device on - ONLY the power button will do this.
Any suggestions?
Well, that IS the way that the Wizard works! It shouldnt be turning on when you slide the screen if the device is in sleep mode...so I would say that it has something to do with the ROM. Try hard-reseting or flashing again my friend and see if it helps!
Yeah, but we are talking the slightest tap or millimeter and it turns on.
I'm going to try a reflash and hoping that it's not a hardware fault.
Im sorry, I said that wrong. The Wizard SHOULD NOT turn on when you open the keyboard, if you have powered it down with the power button or it has turned off automatically via time-out. It should only wake from sleep if you press the power button, sorry for the confusion!
Though it does indeed still seem like a ROM problem to me!

Screen Turning on delay !!!!

Rom: Olyfr sbf upgraded to 4.1.5.7 from 4.1.2.6 via OTA
Not rooted
I have not yet modified the power button.
'Cause I set up the fingerprint unlock,Im used to swiping my finger after press the power button.
after pending or standing by a while(maybe),It vibrates once after my unlocking through scanning fingerprint.But!!!! The screen is still black!!!
Meanwhile,touching the four buttons on the bottom,it still vibrates!
And waiting for seconds,Screen on~~~~~
Symptoms sound a lot like my Bell Vibrant before it died after the Froyo upgrade.
Have you tried resetting your phone yet?...
Okay,I have flash it to 4.157sbf,and temporarily nothing goes wrong
I have the same symptoms. Sometimes when I push the power button it takes 3-5 seconds or more for the screen to light up. I did a power off and on and it works better. Not sure what is causing this but it is annoying.
I've had this on.both my atrixes and it seems to.resolve itself as the phone gets older

I have had the same issue on mine. It occurs intermittently. Not always, but sometimes. And when the screen is turned off, I push the power button and nothing happens for about 3-5 seconds. Sometimes longer.
I do also have the fingerprint security feature on, though I am not sure if that that has something to do with it. However there is another problem with the fingerprint security.
Sometimes I want to check the time so I just turn on my screen and quickly turn it back off. But the screen turns right back on cuz it recognized my click as a fingerprint. However since it is too short to be recognized, it just turns my screen back on and says to try again. I try to turn the screen off again and the same thing. This also happens on occasions.
They need to make the power button better so that ways it does not recognize a screen turn off as a fingerprint swipe.
I have had similar problems. Rebooting has usually fixed them, at least for a while

Screen blank on power on

I've had a problem with my E900 since I got it with regards to the screen. I was hoping Mango might fix it but it doesn't seem to have.
Sometimes if I press the power button the screen backlight comes on (i.e. screen goes from off state to powered) but there is nothing on the screen. No amount of button pressing will cause the screen to show anything.
If this happens I have to turn the device off again (backlight then goes off) and try again. Sometimes it can take 2-3 times before it turns on successfully with the lock screen.
I also have this if an incoming call attempts to wake the phone and also alarms too.
Does anyone else have this issue?
I confirm this one popping sometimes. Not that often that it becomes annoying, but nevertheless.
Did you find a solution to this problem? I am experiencing it too and it is very annoying!
I've recently inherited one as well (E900 that is).
The one I have has been dropped, the backlight powers, but no drawing on the screen.
I've disassembled and re plugged everything (bugger stripping down!) but still no luck. I've done a VolUp+Down+Cam+power hard reset, and when I plug into PC Zune says setup needs completing (so it has reformatted) but still no luck.
I cant see anything fried, and no damaged ribbons as far as I can see, any ideas?
I sold the phone a while ago, and never solved the problem. I think it's a firmware issue.

hi.
What do you mean "somethimes if I press power button"?
Is it pressed with purpose to lock the phone, press it to turn off phone (background slider shows to power off - on Mango and beyond version) or press it accidentally?
Cheers.
So, I did a phone reset. Unfortunately the issue is still present!
Sometimes when I press the power button to unlock the phone the screen is lit, but stays blank i.e. no lockscreen wallpaper, no nothing. The same happens sometimes when I get a phone call - the phone rings and vibrates, the screen is lit but stays blank.
When this happens I have to press the power button to put the phone into sleep mode and press it again to wake it up.
What I found is, when the issue occurs the screen is actually responsive. For example I can slid up and unlock the phone then I hear the unlock "pop" sound. It's just that nothing is drawn on it!
I was wondering if anyone else experienced the same behavior and found a resolution. Also I am not sure if this is a software or a hardware problem. If I could confirm it was a hardware problem I would call LG and have the phone repaired or replaced.
i have exactly the same issue as you, it gets really annoying.
i heard from someone online that the only way to resolve it is to replace the motherboard

I am pretty certain this is a hardware issue. I am calling LG tomorrow and hopefully they'll take the phone for repair/replacement.
I sent my phone for repair. Today I got it back, and guess what?!
The issue is still present! It seems, they "couldn't reproduce" or something.
What should I do now?
EDIT: If anyone is interested, here is a video I just captured which clearly demonstrates the problem. http://youtu.be/38kF9RYs_bU
I'm sending the phone back for repair tomorrow with this video attached.
Hey, might not be an issue at all, but in the video, I saw that the two times you were able to get it to go blank you had your finger on or near the proximity sensor. I wonder if there is something that could be the trigger.
Just wondering if you can duplicated it or cause it only when you have the proximity sensor blocked, or if it truely is random.
You are right, it might has something to do with the proximity/light sensor.
On the other hand, this issue occurs even on incoming calls when the phone is placed on a table, screen up and nothing around the sensor.
Today, I visited my local carrier shop and left the phone for repair again. They told me, since this is a second claim they'll run it through the process faster, so I expect to get it back next week.
Will post an update.
UPDATE: My phone was replaced. Yesterday I got a brand new unit, yeah! It was stock wp 7.0. I plugged in my sim and used the phone the whole day, no sign of blank screen issues. Last nigh I installed all the updates (total 5 I think) up to OS 7.10.8107.79, FW 1.0.16.10. Guess what?! Same issue!
I am crushed

Sometimes screen freezes then phone reboots (¿battery problem?)

Hi, first of all this is my first thread, i hope you guys can help me. Sorry for bad english
I own a S5 G-900F. The phone was working fine until the screen started sometimes, ramdomly to turn black (with ramdom pixels in colours inside) like 5 seconds, then turns off and the phone restarts. This can happen 1-2 times a day while im browsing or doing anything, or even when i turn the screen on to unlock the phone, it turns on and this happens.
I think its a battery problem, it has 2 years and it might be giving low voltage (i have no idea), or maybe a motherboard problem? some water entered inside the case but im not sure.
Another thing i have to say, the "back" button works, as the menu button, but the "back" button has no light. This is weird and i think its related to the water problem. Both buttons work good, but the back button sometimes doesnt light up.
Thank you for the help
