Home and Back buttons not responding please help

Hello,
This issue began about 2 days ago, i noticed every once and again the home button would not respond but i figured its just a glitch or something. It got worse and worse till the point i am now, both the home and back button wont respond at all, earlier today they would work randomly and not often ,ive rebooted it ,reseted it 3 times, but the problem remains. I did not root it, or install any dubious software. i dropped the phone once,about a week ago from my hands,no scratches and it worked fine after that. Im really dissapointed about this, can anyone offer any advice?Thanks

[Q] TP2 'Align Screen' Infinite loop

I was running MightyRom for almost a year, no problems. Suddenly about a month ago my screen alignment was occasionally wacked, by a 1/4 inch or so.
But the alignment screen function no longer worked, I had to restart the phone to exit the application.
Yesterday I flashed back to the stock Sprint ROM and removed the SIM card, I'm giving the phone to my kid so I wanted to reset it to factory specs.
So the 'startup for the first time' sequence begins and the align screen application simply will not 'align'. The crosshairs just prompt me to keep pressing for alignment but I cannot get past this to get to the Home screen.
I hard reset the phone several times from the bootloader screen, even tried to re-flash the Sprint ROM again, but no avail.
Any suggestions? I've been all over google looking for solutions.
I should also mention that it's a brick since I can't make calls/text, etc.. I'm stuck on the 'align' screen.
I took it to the Sprint store, they confirm that it must be a hardware issue.
Rep ordered me a new one, says it will be in by Monday or Tuesday, just have to activate an old phone for the weekend.
0 deductible!!
I'm glad that I got that Sprint ROM back on it just in time.

screen not responding to touch inputs? (not sleep of death)

anyone had problem with the screen not responding after waking up?
There's no way to turn off the phone / make it respond unless to unplug the battery and plug it in again. Had this problem on the first GN and my second replacement GN.
Yep, happened to me the other day as well. There was a crash right before which made the phone reboot. Once it came back, the hardware buttons responded fine but the touchscreen was dead until a battery pull.
Hasn't happened since though.
Had this at lunch today also had it a few days ago.
When returning from sleep the touch input seems to be completely unresponsive.
I left mine for a while to see if it recovered, it did, it came up with the crash report for "System Process" The screen was then responding fine.
Weird. This is indeed different to the sleep of death, because the screen comes on.
Although maybe it's related in some way?
This just happened to me, and so I googled to find an answer. It thankfully led me here. It's like you guys described: I just tried unlocking my phone, but the screen was completely unresponsive. Not a single touch would register, even when trying to touch the Power Off option.
I read robaldred's comment, so I decided to try the waiting game. Thankfully, after a few minutes the screen just came on and the device was ready to use. I don't believe I saw a crash report though.
I hope this won't become a serious issue. I'd hate to be stranded at a point when I need to use my phone.
I had this problem too. have you guys used custom notification sounds?

I had this exact problem and I found it was due to Juice Defender (I have the Ultimate version as well). It kept happening after I installed and but since removing it over a week ago no problems.
Just had it happen here, had to pull batt. Using BatteryXL but will keep it on and see if it happens again.

[q] screen is glitchy after dropping!

Two days ago, my T-Mobile Samsung Galaxy S3 dropped out of my coat pocket as i was running for the bus. I picked it up and saw the screen was cracked along the top left and bottom left hand side. Everything was working for the past two days and i figured i'll just wait till Christmas to get a new phone. This morning i took my phone off the charger and turned it on. The Samsung logo flashed, and then the boot animation for Slimrom (the custom rom i'm currently running on) flashed for about a second but then the screen went black. I did a battery pull but the weird thing is whenever i put my battery back in, even without touching the power button, it boots up by itself but then the screen goes black again. I can access TWRP and download mode but they both go black after a few seconds as well. I was able to successfully turn on my phone and have it fully function for about 15 minutes after putting it back on the charger, but it quickly blacked out again. It also keeps randomly booting up by itself which is weird. Im guessing this is a problem with the screen itself, but could it be a software issue because the device keeps booting up by itself? If it is the screen, will i have to buy a new one or is it not worth it? I've also tried using a different battery and i have the same issue so it can't be that. Any help is appreciated!
Sounds like an issue with the power button, it probably got stuck somehow either when you dropped it, or after you dropped it. Do a simple search for power button and you will find ways to fix it!
Holy crap i didn't even think of that! It makes total sense since every time i even tap my power button, even for just a second, it turns on. I've read around that clearing the cache or a factory reset could work. Is this true?
Unlikely, unless it's a software issue but it's always a possibility. Slam the phone against something to try to get the power button back into place, or open it up and try to see if you can fix it yourself, or replace it
The problem seems to be gone. I haven't had any issues for two days now. All i did was press the power button really hard multiple times. Thanks for you help man!

LG G3 unresponsive/extremely slow

Hello there. I have to write this again becuase the last topic I wrote didnt get posted...
I have a big problem with my G3 and I have tried everything I could but nothing helped so I hope you can help me.
First of all my phone is only stock. I didnt try rooting it or installing custom roms on it.
Heres the whole story of what happened:
A week ago my phone started to act strangely. When I tried turning the wifi off it restarted or froze for a bit and then went on normaly as if nothing happened. I didnt even have to input my pin. Then one day I got home and the phone simply started reseting itself constantly. Always loaded up to the pin screen but I didnt even have time to input the pin and it reset it self again. This went on for like 15 reset before I lost patience and pulled the battery which didnt help at all since after being turned back on it went back to the reseting. I found online that it was probably a battery problem but I was impatient (shipping to my country is over 2 weeks and buying a battery in stores here costs twice the normal price of a genuine battery but only for a "fake" battery) so I factory reseted it via power button+volume down. After that it worked normally but I lost all my data.
The day after this I spilled ice tea on the phone. I opened it, cleaned it and let it dry out. Turned it on after an hour of drying and it worked but after maybe 2 hours it began freezing. When I tapped on the screen it didnt react, when I pressed the power button it took more then 10 seconds to react to it. It turned on, didnt react to touch and then in mere seconds it went dark and then turned off. I couldnt even unlock the screen. Tried pulling the battery but then it wouldnt even turn on. It stayed on the LG logo. I left it on the logo and on the charger and after an hour or so it turned on and worked normally so I took it apart and cleaned it once more even under the screws and such and it worked after that. Until today.
The freezing problem returned. I was playing a game on it and chatting via messenger when the phone stopped reacting. I had signal, wifi, I got new notifications and basically everything on it worked but the screen didnt react to touch and when pressing the power button it took over 10 seconds to light up the screen, then it went darker and then it shut down. Couldnt do anything. After I pulled the battery it would get stuck in a boot loop for maybe 10-15 minutes and then load but the phone couldnt be used. Just as before the screen turned on with a delay but no reaction to touch whatsoever.
I tried factory reset, downgrading to a lower android version (from 6 to 4) with LGUP and lg flash tool, and I bought a new battery. Nothing worked. I managed to get it to android 4 but that didnt help either. I though it was a problem with 6 because the problem started after the update, before that I didnt have a single problem with my phone.
Now its in a state where it doesnt work. The phone is running, apps are upgrading after the factory reset and all that but I cant do anything with it. Once in a while it will work normally as if nothing but that is rare.
Could you please help ? I love this phone and I dont want to have to sell it for spare parts.
EDIT: I left the phone running to see what would happen an after several hours an error message appeared saying "Process system isnt responding". After pressing ok it worked fine. How can I fix this. I googled it but all I found was a problem with sd card (none is inside), with battery (I have a new one) and with rooting (mines not rooted).
