This started happening about two weeks ago. During a call when I pulled the phone away from my face in order to press the end call button, the screen did to wake up. I could not end the call. This has been happening quite regularly now. The screen simply does not turn on after or during a call. Even if the other person ends the call from his side, the screen on my phone does not start.
I was using the stable version of the official CM7 at that time so I flashed the rom again. Since that did not work, I did a clean installation of Mebitek's CM7 without restoring any backups. But I am still having the problem. I am now using the power button to end the call like a handicap person would.
I think something might be wrong with the proximity sensor or my battery. Since, I have absolutely no expertise of how the phone functions, I seek help from you guys. Please give me some suggestions.
try changing the proximity delay
Flash new rom.

AW: Screen not waking up after call ends or during call.
Do u use a screen protector? I heard some might cause problems with proximity sensor.
Screen protector and wakelock

I used to have this same problem. The problem seems to be a combination of the screen protector/case getting in the way of the ambient light sensor and therefore not allowing the phone to accurately measure ambient light, and the phone going into some sort of sleep mode. I usually wipe my ambient light sensor off, and adjust my silicone case to allow the light to come in, but the thing that solved the problem for me permenantly was running the small app called wakelock to keep the system from going into complete standby. I am sure that this solution affects battery life, but I still get 10-12 hours between charges which is enough for me.
This thread talks about a similar problem, and this is where I got the idea to try this fix for our problem: http://forum.xda-developers.com/showthread.php?t=1491223

No no no guys.. don't bother with reflashing and stuff, that's not the problem.. I had the same problem and I googled it for months until I've learned its a Samsung wifi hardware related problem and mostly Galaxy devices are affected. Something is wrong when phone goes in standby. It continues to work but you can't wake it and you have to reinsert battery to get it on again.
The solution is to install a tiny app called Wake Lock, it's there on market.. it keeps phone awake even when you lock screen. My phone doesn't shut off anymore and I can finally rely on it. I don't have to think anymore and check all the time if the phone is off and if I'm going to miss a call...
The alternative is to turn off wifi before you lock screen but I think that most of us need wifi on all the time to get mails and messages on time

Galaxy mini doesn't have ambient light sensor.

I am of course mistaken. It is the proximity sensor that is malfunctioning due to the screen protector and case.

Where to locate that setting?
Hi,
I just got my XZ a few days ago and experience only one issue: When doing a call the display turns off immediately, but when I put the phone away it's still off and doesn't turn on again. Service menu says the proximity sensor is turned on.
Anyone else with this problem and maybe the solution?

Most of the time with proximity sensor not functioning is because some Screen Protector is blocking it.
Make sure your custom screen protector isn't blocking it first, then if it still doesn't work properly maybe it's a hardware failure, should contact SONY then....
If it's the sensor or the screen protector (which has cut outs for the sensor), then why does it turn off the screen correctly the moment it put the phone to my ear?
It was the screen protector. Strange, other people don't have any issues with it.
So sorry Sony, your are great
Might be a little bit late, but maybe for others
worked pretty well on my Samsung S4.
download the app "proximity fix" from the playstore and run it.
Job done.
Hope that helps you or anyone who stumbles upon this!
I just got the phone last week and it’s always had a screen protector on it. I know many have issues with the proximity sensor covered but I don’t get how the phone should work. All my other phones turn off the display as you put the phone to your ear and on again if you move it away to look at something or end the call. The Nexus 6 just stays on until the screen time out and then I have to tap the power button to get the screen back.
I installed a proximity sensor app (Proximity Sensor Finder) and it seems to work fine though I don’t know what the readings would be without the screen protector covering it. It shows 5.000305cm until my hand gets within two inches or so and it jumps to 0. The app says some sensors are discrete so seems ok and the readings are very consistent and fast. So why is the screen not turning off?
Also, the Ambient display setting says it will turn on the display when you pick up the phone or get notifications. Never worked. ???
Bad phone, software or setting?
Thanks.
P.S. Why in God’s name are the volume buttons and to a lesser extent, the power button, dead center of the phone? I hit them every flipping time I pick it up. Is there a way to disable the volume buttons when the screen is off?

my suggestion would be to take your screen protector off. when you pull away from thd phone, the screen should pop on, but it not doung that for you. over the past 8 months or so, ive been reading about this same issue. and its always fixed by raking off the screen protector. im fuessing that your screen protector is covering one of your sensors.
Understood but:
"I installed a proximity sensor app (Proximity Sensor Finder) and it seems to work fine though I don’t know what the readings would be without the screen protector covering it.

Can someone without a screen protector on chime in with naked sensor readings?

your phone has its own proximity sensor thats being blocked by your screen protector, probably. im telling you that of the very many that have been reporting thus issue, have no more issue when they remove the screen protector. its worth a try, isnt it?

for most ppl it stays off, a few that ive read stay on non stop.
for example.. if it doesnt "see" your face get close, it wont turn off the screen.

Kewl. He needs to make sure ambient display is on in display settings. Also the buttons are in middle of phone so you can reach them holding phone normally.

Yea, but the protector would not be usable afterwards and it was really hard to get it on clean and lined up and the sensor readings are the same. I thought the folks that had problems had stuck or sporadic readings.

Mine can be toggled on and off with the power button, never gets stuck. It just acts like the proximity sensor mode during a call never activates. It only powers off after the normal screen timeout if you are still on the phone. The sensor does see me and sets the value the zero.

It’s on, even tried toggling it.
The buttons should be higher. I understand you can’t reach the power button on larger phones if on top of the phone but putting the volume at the center of gravity is crazy. It’s actually noticeably difficult to hold the phone without it dipping when grabbing it lower and that’s after training myself to grab it lower. I still forget and grab it in the middle like any brick sized object. I'm old, hands weak.
I have read here, somewhere, that the proximity sensor does not have a variable output. It's either off or on, so to speak.

Probably yes but everyone who had a screen protector without a sensor cut out had to change it for one with a sensor cut out.
This is step 1. Even if this isn't the cause, it will cause problems later.
You say not variable. Sure on or off. That said, a protector can limit how close the "close" reference can be identified at.
Step 2 is a factory reset.
Unfortunately, can't troubleshooting without doing these steps.

That is my understanding also and someone posted above that they have the same readings from the sensor without a screen protector. They did not say but I’m assuming their phone works as it should when on a call. Again: "I installed a proximity sensor app (Proximity Sensor Finder) and it seems to work fine though I don’t know what the readings would be without the screen protector covering it. It shows 5.000305cm until my hand gets within two inches or so and it jumps to 0. The app says some sensors are discrete so seems ok and the readings are very consistent and fast.

I know, I know. I’ve read that many have had issues with screen protectors but I thought the folks that checked saw that the proximity sensor readings were also bad. Mine seem to be just what the phone would want to see.
I will take it off at some point and I guess I’ll be the first to verify that even if you use an app to monitor the proximity sensor readings and they look normal the protector can still cause an issue or it is something else.
I did find that the Ambient display will not work without screen lock turned on.

True, because it needs a lock screen to display it.
The screen worked as it should randomly the other day. Only on the one call. I pulled the phone away to look at something and it turned the screen on. Put it to my ear and what do you know, it turned the screen off. Not worked again so far and I ran the sensor app right after the call and it showed just what it always has, zero. Anything close to the phone you get a zero every time, right away. The phone app just ignores the zero reading.
did anyone notice the Always on Display dims, but doesn't turn off when turned face-down or put in your pocket?
Yes and looks as though that is how it will always be now. I read an article about how they did proximity sensor on this phone. The process sensor causes a white light to blink when it's on so it is only used when on a call.
Wait ... So the ALWAYS ON display is on ALWAYS and that's a problem??? Hmmmm
Try Gravity Screen.

This is bull s h i t! WTH!!
Yea, I was looking into this. The "behind the glass" proximity sensor isonly on when in calls etc. You'l see it's on by the flashing white dot near the battery icon when in a call etc. All other times it seems it's off. So AOD is always on as it doesn't use the proximity sensor any longer.
Really stupid on their part.

I agree, Also I used the lift to call when in a persons sms thread in the stock messages app, now that does not work either because of this.... I can't find an option to turn it on. Never had an option on my prior galaxys as it just worked...

Yes because I want it always on WHEN I CAN SEE IT, not when it's in my pocket.

Have you tried it for this case?
This sucks... Only way I understand this it's that they decided that AOD and proximity sensor always on consume almost the same amount of battery.
I cover the proximity sensor on s9+ and turn off AOD in 30sec and then i try that on my s10+ and nothing happened and for now i turn it off because is all the time active.
Screen On In Pocket
My phone doesn't arrive until tomorrow so I have no report but, I am wondering if anyone has noticed accidental screen on in pocket or seen a setting to prevent. Older Galaxy phones had a setting to prevent this which relied on proximity sensor.

Accidental touch is still an option on the S10, i have mine enabled but it never turns AOD off. It doesn't work like before. I'm hoping they can fix this as its getting on my nerves that I have to keep disabling AOD when leaving in my bag else it'll stay on wasting battery for nothing.

So basically if I use a wallet folio case then then AOD doesnt turn off when I close the cover?
What would be causing this?

Probably need to be connected with proximity sensor but this time is under the screen who knows.
I just ran the Samsung inbuilt test *#0#* , there is no test under Sensors for the proximity sensor for this model, if I'm not mistaken other Galaxy devices did have this specific sub test under Sensors test menu

Anyone else having this issue? I have to either tap phone or tap power button to get screen to turn on, then face unlock will work. Previously I would be able to just hold it up to my face with screen off and it would just unlock. After most recent update it no longer does this. Very frustrating.
Check maybe lift to wake phone is turned off in the settings.

Mine was doing that too...along with auto brightness stuck and the proximity sensor wasn't turning the screen on and off during calls. As a last resort before sending it back (since I had to wipe it anyway) I tried the first android 11 beta (not 1.5). It almost completely fixed everything but the proximity sensor. Still had to occasionally tap the phone or power it on to face unlock though. Google replaced it because of the proximity sensor. The replacement phone is working fine on latest update of 10
