[Q] Can not end calls - Verizon Samsung Galaxy S III

Every time I place a call it connects, but if the screen turns off it will not turn back on. I have to battery pull to end a call or the other person has to hang up. not terrible if all my calls get picked up but if it goes to voicemail there is no way to stop it. I started having this problem about a month ago, did not exist before. I originally was using cleanrom and used power button to end calls to get around this but am now on CM10 and having the same issue. I don't have the power button option this time. I haven't been able to find anyone with a similar problem and I'm not sure how to troubleshoot this one. any ideas?

Disregard this question. I found that it was the type of screen protector I was using. I thought it might have to do with the sensor, as the problem persisted through different ROMs so I cleaned the screen and replaced the protector, still had problems. However, after removing it completely and trying again bare screen, I found that everything worked fine.

[Q] Has anyone got a blank screen after moving around alot

Ive gotten it maybe 5 times since I bought it, although the latest updates have been stable. I still got it a few days ago though. Basically if I have the dock, and close the lid and say rotate the whole device or just move it a certain directions, it will make the screen stop displaying when trying to open it again. The lid opens, you hear a noise like it unlocks, but the screen is black. I try unlocking and locking, undocking, but its still black unless I reset the device via power. Anyone having this issue? It's not a serious one yet, but id like to know why it happens in the first place.
I have similar experience without dock.
I put it in carrying bag and drive to subway, when I take it out and the screen is blank and I can reboot it by power button. It happened 3-4 times under same situation.
I updated to 3.2 and problem didn't come back so far.

Proximity Sensor Issues Nexus5

I got my nexus 5 just last month and is pretty much in the condition that it came out of the box. Don't even have too many apps downloaded yet.
My problem is that every call I make I have AT LEAST two disconnects because my cheek seems to have pushed the disconnect button. When I look at my screen after the disconnect, the screen is zoomed in and sometimes is even making another outgoing call from my speed dial list. I once had about 8 call drops in one call
I used to have a screen protector which I have pulled off, but the problem still exists during EVERY SINGLE CALL. When I put the phone on a table during a call and hover my finger over the sensor, the screen goes black right away. But when I hold it to my ear I can often see my screen blinking because its changing screens at random. I've tried holding it only on my right during the call, still happens. Only the left side, same result. Am so frustrated.
Spoke with google help several times. Did a factory reset 4 days ago. That fixed my screen freeze problem , but not the sensor problem. Since I'm in warranty, my option is to send it back to google for a replacement REFURBISHED PHONE. I can't even get my money back. Am so mad at their ****ty customer service.
Does anyone have any ideas on how to fix this, since I really don't want to exchange my brand new phone for a refurbished one.

Two options I can think of: Turn the screen off during a phone call, or hold the phone so the proximity sensor is situated where your head/face is. The sensor is pretty far to the right so it can occasionally miss your head thus turning the screen on.
I'm bumping this instead of posting a new thread. I'm having the exact same problem on Mahdi rom \ stock kernel.
This problem makes me crazy! I'm disconnecting so many calls!
Hey, any help??

Screen randomly turns off but phone still on, backlight often stays on

Hey guys, i'll try to explain the situation as best i can below, hopefully someone can work out what is wrong.
My phone is about 16 months old. About 2 months ago i dropped it twice within the space of a couple weeks. There were a few cracks along the screen, however it wasn't very noticeable and i wasn't going to bother having it fixed. The problem started a couple of weeks ago when i went to grab it out of my pocket, however i found out the screen was black and it wouldn't turn on. I don't really know how to describe it but it was acting very strange...
- The screen would have white/gray bars all over it then turn off, then it would do the same with very thin vertical lines that were white/gray/other colours...
- When i get the screen on, it generally turns off again within 30 seconds, however it can stay on for a few minutes.
- If the screen is on and i press the lock button, it almost certainly won't come back on.
- Restarting the phone or holding the power and volume button nearly always gets the screen to come back on. It often then restarts but turns off again shortly after.
- The phone is otherwise still working when the screen goes off; the notification light stays on and i hear messages etc coming through
- The backlight often stays lit, revealing a gray screen opposed from total black. Sometimes it does not stay lit however.
- When the screen came on it was often unresponsive to touch
I had the screen replaced yesterday by a phone repair shop and the phone is still not right. I have factory reset the phone and also wiped the partition cache. Other than that it is still not working. IT seems to be working better... The screen always seems responsive to touch when it is on, and it doesn't seem to be turning off as often. It generally starts up and works fine when i start up by holding the power button and down volume button together... However even still it sometimes just flashes up with a few thick white/gray and black lines on the screen..
Does anyone know what can be causing this and how i can resolve it? If you need any more information please let me know and i will try provide it. I could try get some pictures of what the screen is doing when i finish work. Thanks guys, i appreciate any input.
EDIT: I managed to get a pic of what i mean by the thin vertical lines all over the screen. This just appeared when i tried to restart the phone after it the screen had once again stopped working. The imgur link is gIFMGD6
Anyone have any ideas?
Hey, did you ever figure this problem out? My phone just started doing the same thing. Can't find much info about it.

Yeah, i had the screen fixed hoping it would fix it, however that didn't work. Turns out it was the motherboard, don't know what was wrong with it in particular other than it was simply going faulty. Had someone replace the motherboard on it for $50 and have had zero problems since! Hope that helps you.
Thanks for the response. I tried replacing the screen too with no luck. Unfortunately the same place that replaced the screen said it would cost $400 to replace the motherboard!!! The phone cost less than that so it looks like I'm gonna buy a new one.

Nexus 5 really weird screen problem

Hi,
I have this really weird stuff going on with my Nexus 5 screen. I cracked it a couple months ago and bought a legit replacement screen for it and installed it myself (glass, lcd and frame). I fixed it with good instructions and it worked properly for two months. However though, now when I take it out of a pocket and try to turn screen on, sometimes it just doesn't light up. It's still on and every button works but the screen doesn't turn on. I have to give it a light tap or two on the back in order to make it light up again. Same thing happens sometimes when I'm using the phone normally, the screen just goes black and goes on after tapping it couple of times. Otherwise the phone works normally like it did when I bought it two years ago and after running couple of tests with screen, everything seems to work from touch interface to the graphics card.
Tried looking it up, no results.
I've noticed that the front camera doesn't work for some reason (probably just broken) and the battery lasts in use only 2-4 hours which isn't that much of an issue since I'm looking for a new phone. I just want this one to last long enough till I buy a new one.
It comes up when tapping the screen or power button? It could be a power button issue.
The screen comes back on when tapping the screen or the back of the phone. The power button isn't the issue. The screen just goes black but nothing else happens. It doesn't turn off or go to sleep mode.
Strange issue. I've never experienced it and any problems I had were related to the power button.
Could it be a loose connection inside the phone? Maybe an issue related to the proximity sensor?
Thats actually what I've thought. I have checked the phone's insides twice and didn't see loose connections, and the problem feels like it's related to proximity sensor since the screen going black happens exactly same way that when calling someone or doing something else where proximity sensor shuts the screen. It's really weird though...
Huh, I took backplate off and unscrewed the motherboard cover and took everything apart and rebuilt it and now the problem is gone. Seems like there was just some bad connection somewhere.
Glad you got it to work without having to pay someone to fix it

Backlight turns on, unable to display anything

I bought an Xperia XZs from a website called DWI Digital Cameras about a year ago (they've closed down recently due to the new GST regulations). I've had this issue since the day I received it and I thought it wasn't that big of a deal at the time, but it's gotten to a really bad point now.
The issue is that very often when I try to wake up the phone (like almost half the time) the screen does not display anything while the backlight turns on. The backlight might also flash multiple times as if it's trying to get the rest of the screen to wake up. This issue would usually go away for a bit if I either tried to open a camera app from the lockscreen (via double-pressing the power button) or rebooted the phone - the backlight would turn on and off a few times and the rest of the screen would temporarily work again. But now, it seems to be not working no matter what I try.
I'm pretty sure that there's nothing wrong with the screen itself, I even got it replaced once after I accidentally dropped and shattered it and the issue still did not go away. The issue also persists no matter what ROM I have installed as well.
Any experts on this? Cheers.
