Hello. I've had this device for awhile now and it's probably the best phone I've ever had.. except I started to have problems with regards to calls just recently. I actually rooted the device about 2 months ago and am currently using the Rombie mod v2 (JPC), if that helps. Anyway, the problem happens in the middle of a conversation, where the proximity sensor somehow disappears and the speaker mode is activated on its own (or maybe it gets in contact to my skin, I'm not sure, since the screen is supposed to remain blank). After that, the device becomes unresponsive: the touch sensitive menu and back keys don't work, and neither does the screen itself..but the hard key home button works and I could still hear the other caller via loudspeaker. I force a reset and everything goes back to normal (I mean this call issue doesn't happen all the time). I don't have any screen protector to affect the performance of the sensor. Anyone can help me out with this? Thanks!
Hi!
Because I didn't get any answer in the help-thread I try it this way.
When you receive a phone call on your XZ, does the screen turn on again when you move the phone away from your ear?
This problem drives me crazy! Every phone call (active and passive...) the display of my phone turns off (as it should) when I put the phone to my ear. When I put the phone away from my head, the screen doesn't turn on again. I always have to press the power button to enable the display again. In rare cases, the display turns on as it should. But when a phone call is longer than a few seconds, the display won't turn on again.
The only reason for this problem I've found on the internet is the usage of a screen-protector. Actually I have a screen protector installed, but is has a cutout around the proximity sensor. I've also tested the proximity sensor with an app - it turns on/off correctly when I move my hand in front of the phone...
Does anybody of you experience this issue? I've tried a lot of firmware versions, but it's everytime the same... No matter if I use CM10.2 or different stock roms...
I hate it so much - not being able to stop a call before being redirected to an answering machine only because this piece of shi*** refuses to turn on the display during a call.
I'm looking forward to your answers - I can't imagine that my XZ is the only one that shows this behaviour.
Regards
is there really nobody with any screen on/off during call problems? can't imagine that my XZ is the only one... or is there an android-"feature" I donn't know?
I've already removed my screen protector... but nothing has changed...
I also have this problem frequently, i enabled power button to end calls under accessibility setting so if i press it, it ends the call, so could be partial solution to allow you to end calls, but not a real solution at all if you want an option not to end the call but to have the screen turn on only. Let me know if you find any other solutions

Actually stopping phone calls isn't my main problem. But it annoys me that I can't check the current time by removing the phone from my head for a second. Also when I have to interact with an answering machine (windows activation hotline for example^^) - everytime I have to input a number during a call this f*cking screen is off and I have to press the power button.
Don't people use their XZ for making telephone calls? Am I the only person on earth who uses the phone for other things than watching movies and surfing the net?
I also want to know if this is a general Jelly-Bean problem... If so, replacing my phone with another one would be meaningless.
Press the power button twice to activate the screen during call.

Pressing the power button ONCE also works to turn on the screen during a call. But that's the point. I do not want to press this damn power button. What does the phone has a proximity sensor for??? When I start a call and remove the phone from my head after a few seconds, the screen will mostly turn on itself. But after a while (a minute or longer) moving the phone away from the head will not turn on screen anymore...
Is it too hard for phone manufacturers to build a phone that can be used as a phone? If I wanted to have a tablet I would have bought one...
Problem solved. I have a Nexus5 now and it is just awesome. May the new owner get angry with this piece of sony sh*t.

Hi,
Have not posted in here in a while but i'm having a huge problem with my HTC one M7.
Had the phone for a year now and suffered a problem with it once before. The problem before was something to do with the phone locking itself and required me sending it off to HTC to repair. It kept bootlooping and wouldn't allow me to do anything at all.
This problem hasn't occurred since repair however last week the phone was working fine until the next morning when i woke up. My girlfriend used my phone to send herself some photo's and then put the phone on charge as the battery was running low. When i woke up the screen stays black and wont allow me to do anything. If i hold the power button the bottom two lights flash and i can hear the phone booting itself back up. I have a feeling the phone works since everyday at 6:15pm my alarm goes off and i am able to deactivate the alarm by swiping up (i remember the location of the dismiss function) it would appear i'm also able to receive calls and texts since i can hear my message and ring tone going off however cannot see the screen.
I have tried a few things such as holding buttons to reboot, shining a light onto the sensor during a reboot and fully charging etc however nothing.
I should also add i have a slight hairline crack in the screen which occurred about 9 months ago but didn't appear to affect the LCD at all or the digitiser either. Any help would be highly appreciated or any tips on stuff to try.
more information available if needed.
Many Thanks

It looks like you tried all of the usual methods, sorry but it might just be the screen is shorted.

I thought as much, i have ordered a new screen and once its delivered i am gonna attempt to fit it and see what happens, thanks for the reply.
Hi all, I have an old Sony Xperia V that's been working perfectly for a good few years now, but recently it's developed this infuriating problem with the touchscreen, where it randomly acts like somebody is holding down the onscreen back button, and you have to turn the screen off and then on again to make the problem go away. Sometimes it also does this with the homescreen button, but most of the time, it's with the back button. This problem has gotten to the point that the phone is almost unusable, as it does it every single time I turn the screen on, if I turn the screen off and then on again (as mentioned earlier) the problem usually goes away for a few minutes, and then comes back again, making the phone extremely frustrating to use. Any ideas on what the fault could be? I've never put custom firmware on this phone, and I've never used it underwater. I've cleaned the screen many times with no effect on the problem, and I do not have a screen protector covering the display.
Non rooted, T mobile branded 3 month old note 8. No water damange, no drops etc.
Using chrome one miniute, set the phone down to watch a movie on my tablet, picked up the phone to check messages and boom. Screen is off. The phone works, I can even answer calls because I know where the answer button is on the screen, haptic feedback works, all indicator lights work. The phone screen remains off.
Tried a soft reset (tried hard reset too the best I could being I cant see the screen) and the phone seems to reset based on the vibration and indicator light patters but the screen remains off. It's as if a physical connection between the screen and the brains of the phone has been severed. Literaraly the weirdest thing that has happened to me in a decade of Android phone ownership.
Googled all the black screen issues with these phones and most of them are resolved with just a soft reset... some said that the phone is in it's lowest dimmed state and go to a dark room and i'll see it faintly and then can increase brightness... no luck...
Has anyone experienced this?
I would say it's a warranty job, just tried turning my brightness to zero and you can still see the screen.
I did have a similar problem on an old note that had root and custom rom though but I had somehow set the volume rocker to control brightness and it had lowered itself to minimum in my pocket

Try pressing and holding Volume down and power button for 5 to 7 seconds to force power off, then try to boot to download mode Volume Down + Bixby + Power button and see if the download mode screen shows......if not then probably a bad screen.

so I had it replaced under warranty through T mobile. Refurb phone will come in today. One quesion. Should I let the Tmobile techs do the data/settings transfer from old phone to new one or just do everything myself from scratch (which will obviously take longer).
This happened to my phone twice for the past month or so. (both in Nougat and Oreo - Non rooted) Black screen but phone seems to be responding -- I can receive calls and notifications etc -- And force reboot doesn't fix it. I've also tried drainging the phone when it first happened to me but doesn't work. HOWEVER, it gets okay so randomly. Like I just left it for couple of hours and it just worked when I hit the power button.
I did tried bringing the device to Samsung but what they did is to just manually upgrade/reset the software in their end which I could have done in my part but I just let them do it. They told me to come back if it happens again which is kinda BS.
I can conveniently say this is a Hardware issue. I will wait for it to happen again on my phone and request for a replacement. Phone is 4 months old when it first happened.
I have the same issue with blank screen but phone is working.
It started couple of weeks after i dropped my phone on the ground. There is black dot on my screen and broken glass but phone was working ok and was still pretty usable. But then it started:
Display works fine but when i switch display of, lock the phone or display switched because of its timer it didn come switch on... But phone works, i can use it with blank (black) screen.
I had to do force restart so the display will turn on with samsung logo and booting screen, and keep on till another switch of.
I was trying every setting (but no hard reset) and then i found a little hack:
When you turn on the "Always On Display" (AOD) function you can let the screen switch off or do it manually, wait for 1-2 sec and always on display will come up to the screen. Then when you press home button or lock button screen will swtich on normally. YOu can type pin and use phone witch screen working. But when you try to unlock from "AOD" with your finger or your eyes it unlock but with screen black.
So i was using it like this. everytime you need to wait second untill AOD comes up, but it was working fine.
Problem nu 2 is that now it stop working, AOD is working but when i want to switch screen on from AOD it shows black screen and phone is working on blind.
So everytime after my screen goes black or to AOD i have to unlock the phone blindly and "Force restart" it and have to keep waiting until boot, and then have to never let phone to screen of.
Its not usuable.
¨
Now what do you think? Is it hardware problem or software problem? Because screen is working but randomly. The black dot of dead pixels on the screen is getting slightly bigger in time (about 1 year) but its like 1.5cm round. Maybe this cause the problem? And why hack with AOD was working for half a year and then stoped working? There wasnt any updates right before, but i tried to install some apps (non display related) so ill try to uninstall them.
Hawe you got any idea if i can repair it on my own even if i loose the waterproofability?
Or can it be replaced for free if i have a warranty? (I dont have insurance)
Thanks for your tips guys.

If you're under warranty it will likely be a free repair, unless they find other damage. Like moisture damage.
As far as fixing it yourself, it's just about as cheap to have Samsung do it than it is to buy the parts yourself. It's $229 for Samsung to do it, and you'll maintain the water resistance rating.
same has happened to me

This has just happened to my note 8 too. I was about to update it and had started it. set my phone down and picked it up and phone screen is black but can hear the haptic feedback.
I can only see the lock screen and the notifications. Everytime I try to unlock my phone I only get to see a glimpse of the notescreen and then the screen turns black. Even when I try to go to camera through the lock screen the screen goes black too. When I charge my phone it heats up so I haven't really charged it as well. Has this also happened to anyone? It seems as if the phone's sensitivity still works in all places but when I unlock it the screen just goes black.
I also have problem of freezings and always rebooting. Tried soft and hard resets/factory reset. Still same problem. This phone has hardware issue. Do not buy.
I realize this thread is quite old but I have this exact same issue now. I have managed to discover some other information by playing around with various settings which are noted below. To begin with, I was able to used the AOD hack posted above for a while but it no longer works. The only way I can get my screen to come back is with a soft reset - but as soon as the screen times out or i turn it off, it goes black, with or without AOD enable. All the on screen buttons still work as well as the haptic feedback - I just can't see anything.
Now on to what I have found:
One thing I have found is if I turn off adaptive screen brightness and crank the brightness slider to the right, when it goes black I can faintly see some of the buttons - enough that I can turn the phone off or restart it from the power menu (If I switch the default setting to night that also helps to see the buttons a bit better). Also, if I enable night mode I can also see the brightness slider faintly but when I slide it left, it just makes the screen completely black and when I slide it right, it only returns it to the very faint brightness level.
So at this point I am stuck. To summarize the issue:
1. When the screen either times out or turns off, it is still "alive" but goes black. It will not return to normal brightness.
2. Turning off adaptive brightness and cranking brightness slider to right allows you to see faint buttons after screen times out but won't return to normal brightness.
3. Enabling night mode helps to see the faint buttons, in particular the brightness slider a bit better. However the screen still cannot return to normal brightness.
4. The only way to get the screen back to full brightness (albeit temporarily until the next timeout) is to turn off the phone or reset from the power menu; or soft reset holding volume down + power simultaneously.
Hopefully someone else has figured out a way to recover this. I am on Android 9 with Samsung UI 1.0
Phone is completely stock, never rooted and completely out of warranty.
