Screen lighting issue.

XDA-Dev:
I hope this finds you in high spirits and good health. Just a day ago my phone started acting peculiar regarding the lighting of the touchscreen.
Firmware: 1.6 // Build: DRC83 // Rooted: No
Damage: Slightly scratched hard plastic from dropping 2-3 times. Otherwise, outwardly pristine
Upon purchasing the phone, I immediately noticed that the screen would creak if it was pressed on the bottom right hand side (by the send button). The right side of the screen also protrudes slightly higher than the left when in the open position. I have owned the device for about 7-8 months now and have noticed that on the rear, when in open position, there is a scratch where the sliding mechanism moves. The paint is stripped and the underlying metal is displayed in those areas. And now on to the issue at hand:
When the phone is closed (touchscreen only):
- When pressing MENU, or any key that would normally illuminate the screen, this does not happen. The screen stays dim, yet the lights on the buttons bellow it brighten.
- If I slide out the keyboard while the screen is supposed to be on (meaning the buttons are lit up), nothing happens.
When the phone is open (keyboard presented):
- And the screen is off, if I press MENU, the screen comes right up with no brightness issues.
- At this point, if I close the keyboard, the backlight disables itself. The screen is NOT completely blank. If I reflect the light of the room off of it, I can just barely make out that it is indeed displaying whatever task it was that was open, but if I were in a dark room, there would be no chance of recognising what is being presented.
- Continuing from above, once the screen's backlight is disabled and I reopen the keyboard, it does not turn back on. I must turn off the screen and turn it back on for the backlight to resume normal functioning.
One would think that if the issue lies in a loose wire that once the keyboard is extended that the backlight would regain normal functioning. Because this is not happening and that it is only working under certain circumstances, I cannot accurately ascertain whether this is a software or hardware problem.
Attempted remedies:
- Soft reset (both rebooting the phone by powering off and on and by going into the reset menu)
- Hard reset (by going into the reset menu and hitting ALT+W, etc)
Neither of these attempts succeeded in restoring functionality of the backlight. I've also search high and low through the settings, but see nothing other than 'Brightness' under 'Sound & Display.'
It may be noteworthy that I have the paid application 'Power Manager' installed. Though, perhaps not since this issue was still occurring AFTER the factory reset when no foreign applications were installed.
If you require any additional details, feel free to give a reply with any questions. I'm sincerely hoping I don't have to deal with T-Mobile or HTC to have this repaired. Any tips, ideas or possible solutions would be greatly appreciated!
Regards,
Ian

Update on issue:
On the way home from work, as the battery was on it's last leg (less than 10%), I turned off the screen while the device was in the open position after finishing a text. Upon attempting to re-activate the screen, it would not do so. As always, the side buttons lit up, but the screen was blank no matter what I did. I could hear the vibration from receiving texts and the red 'omg I\'m dying LED' was still flashing, so the device had not died.
Returning home, I gave it a reboot by removing and replacing the battery. I've kept it in the open position since it has been plugged in and am quite afraid of manipulating the slide mechanism any further.
I'll be calling t-mobile to get their opinion on any further troubleshooting momentarily and report back.

Sorry for opening an older thread. do you remember what t-mobile said was the problem? i am having the same issue.

The ribbon wire in the slide mechanism is either broken or pulled out of socket.

display stays blank even when not near ear on phone call

Tried to find in forum but can't
When I phone then screen blanks when lifted to ear - that's good
However when I take from ear (say to enter number from keypad or to hangup call) the screen stays blank. Sometimes comes back at random time.
If I can't connect to something then simply don't get screen back - have to remove battery to reset
any ideas?
Jim

Found the problem !!!!!
I have a ZAGG screen protector. That one must be not invisible enough as it appears to keep the proximity sensor active when triggered (must be very marginal as it sometimes come back)
when I removed the skin it all worked ok - I will let ZAGG know (and wil cutr a strip off the skin in the meantime

[Q] Screen will not unblock during call

When I'm in a call and move the phone away from my ear, the screen will not come back on. Pressing the power button does not turn it on. The only way I found to get my screen back is to shake the device to trigger the camera, then go back to the phone. This makes it difficult to access the keyboard necessary during some calls. Today, I tried to turn on the speakerphone during a call but was unable to see the screen.
Is there something I'm missing about this? I don't know where to look. Anybody else seeing this? I do have a MIME glass screen protector installed but I don't think that should affect the proximity sensor.

I think I found the problem. I believe my case sometimes causes this.

proximity sensor issue?

Anyone else seem to have a problem with the ambient light/proximity sensor on their N6? I've noticed that a lot of times when i make calls, the screen won't shut off when i put the phone to my head... often with that resulting in my cheek touching something, and the person on the other end not being able to hear me. If i leave the phone at an angle against my ear so my cheek doesn't touch the screen, eventually the screen will shut off, but won't come on when i take the phone away from my ear, resulting in me having to press the power button to turn the screen back on.

Had that happen to me yesterday ... Rebooted and it hasn't happened today.

I'm having a issue now. Phone call comes in and screen stays on. I did a reboot, factory reset even installed custom ROM. It was working the other day. Anyway to calibrate this thing? Or do we have a bad sensor.
Also now my phone won't rotate screen.

Do any of you happen to have a screen protector on? As there have been some users that have been reporting issues with certain screen protectors. I believe most are tempered glass protectors that are the cause of the problems.

I took mine off and still nothing.

Did you try going to settings , accessibility , power button ends call, toggle that on and off.

We own two new Nexus 6 devices that are rooted and decrypted. We have the same issue where the phone screen stays on during a call. Rebooting fixes for a short period (hours or so) but the problem comes back. Other threads show this to be an issue with other phones (nexus 5) with Lollipop. Not sure of a fix. These devices are only a few weeks old so it is not a dust issue.

Having the same issue that just suddenly started. Rebooting does not seem to help.

Happening here too. Frustrating.

My screen turns off when taking the phone to the ear but it doesn't turn on again after i take it away from my ear.

It's pretty bad on my phone. The screen turns on when I am on a call making the notification bar drop down. Also, the phone doesn't wake up when I pull the phone away from my fasce 80% of the time. When I am on a call the phone randomly vibrates like I am getting a notification and when I look I have nothing. With all of this going on, making phone calls on this device is a nightmare.

Restore clean wipe did nothing.
nexus 6

The below mentioned fix is for brand new Nexus 6.
Did you try going to settings , accessibility , power button ends call, toggle that on and off.
After completing the above mentioned step. Reboot your phone and try making a call. I hope the issue get resolved.
I tried this step on an unrooted phone, which was recieved just yesterday.
I got this fix from some other thread.

What app

Orzly works fine... It doesn't cover the sensor. The Slimwrap orange vinyl (leather) face was a problem for me, had to enlarge the cutout to get suitable performance. I believe the sensor is longer than it is wide, the opposite of the factory cutout? It frames the face of the phone nicely with this screen protector on and I didn't want to take it off. The 24mm added height changes the profile of the phone alot, it no longer rests on the speaker bars/guards. This must also have effected placing the wrap on as well. The larger cutout box for the sesnor is a detractor, but the sensor works 100%. This is good , as it is my intention to run nekid with this phone but its size precludes using a case with any of the pockets I currently own.

Thanks I was just having a crazy time trying to install the front, similar case (glass protector in front) and ended up cutting a hole for the proximity sensor about 2 times the factory height, everything (seems) normal now. I used this program to help make the minimum cut, and align correctly. Did you run into any issues with the thin left & right vertical part of the front cover? Mine seems to "wrap" around the glass protector, not sure if it will stay there though

Question Extremely frustrated, screen activates in pocket, please help

Please help let me know if screen activating in pocket is a bug or if this is intended design (i.e., design flaw)?
Now that it's summer my leg can get a little sweaty. But my phone in pocket triggers off my leg due to the moisture! Then the phone will randomly edit various things as the phone bounces around in my pocket.
WTF, why won't the phone just detect the darkness and know it's in my F*ING pocket! My S9+ was really good about this, it knew when it was in the pocket and ignored my sweaty leg.
But with this retarded S21 Ultra, it doesn't seem to know when it's in your pocket. I've already lost several important appointments and tasks (my calendar and task lists widgets are on the main screen) because the dumb phone let my *LEG* edit/destroy/delete the important tasks and calendar entries.
I'm holding out hope that maybe this is not how the phone is designed to work, maybe I can fix it by doing a factory reset. But I recall other posts complaining about how the phone is too retarded to detect being in the pocket when it comes to the Always On Display (AOD) and just keeps the display on while in the pocket too. So maybe it's a fatal design flaw of the phone, where if it is hot outside and you have moisture on your leg, your phone will think your leg is typing and just randomly change things.
Please help me understand whether this is a fatal design flaw or just some bug or what!?

please disable the option to activate the phone/unlock phone via sensory detection
i believe you need to deactivate that first from the smart lock - on body detection
and then also go in advanced features, motions and gestures and deactivate lift to wake

Used to happen to me too. Ofter i would only realise phone was awake and messing around by the beeping sounds of the dialer going off in the pocket, or the increasing temperature of the phone against my thigh - screen on for God knows how long.
Pocket detection is dubious at best - doesn't work consistently. All this happened despite it being set to "on"
Turning off double-tap-to-wake screen helped me.
Now the phone only wakes up for calls and will show lockscreen only if I hit the power button (side key) - I have never used AOD, so screen stays off no matter how hard you tap away at the screen.
Unfortunaltely this puts a lot of mechanical wear on the side key (waking up the phone to unlock)
TO solve this, I have set my Fingerprint scanner "always on" enabled, so if i want to unlock phone without wearing out the side key, I just hit the screen with my thumb where i know the fingerprint scanner is, and it takes me to the home screen without showing the lock screen. I've developed muscle memory now and can hit the correct spot on the screen 90% of the time without the fingerprint icon displayed on screen. No perceptible differnence in battery life as opposed to keeping fingerprint scanner always on disabled.
This has worked for me. Maybe you can try it out and see if it solves your issue.

I dont think that would put any mechanical stress on the power key.
Phones are tested for upto millions of press of buttons which you woudnt be able to achieve in your lifetime .
I have my aod on always , and double tap to wake on always .
Best possible way to avoid accidental wakeup is to insert your phone with screen facing away from the body i.e towards the fabric of pants/jeans/lower

Yes, lift to wake was already disabled while the problem happens. The phone still wakes from "taps" caused by the leg.
I want to clarify, the problem is not caused by the phone unlocking or locking.
The problem is because the phone is not ignoring screen taps when in the pocket. It thinks I'm double-tapping to wake the phone.
I'd like to keep enabled the smart lock on body detection, and keep enabled the double-tap to wake. I can see how keeping the phone locked would help, but the root problem is still there - the phone wakes up even though it is inside the pocket.
Keeping the phone locked would just transform this to a new problem - how do I prevent my phone from waking up in my pocket and wasting energy while my leg enters various unlock codes by itself.

Yes, the S21 Ultra refers to this as "Accidental Touch Protection." The flavor text explains "Protect your phone from accidental touches when it's in a dark place, such as a pocket or bag."
Accidental Touch Protection has been turned on when I had the problems.
Does anyone know why Accidental Touch Protection is not working, even though it's turned on?
The setting is found under Settings - Display (scroll down, 4th from the bottom).

Keep the back of the phone towards your leg, problem solved.

Yup, you may be right. Ideally they should last a lifetime. But all mechanical parts are prone to failure. Same thing holds true with charging ports - they shouldn't fail, but often do. Doesn't happen to everyone, but it's something to keep in mind.
I've had my HTC power key fail on me due to constant use over 2 years, and ever since then I've stuck to using the screen for wake-up. Needn't happen to everyone, but once bitten, twice shy, right?
The screen facing outwards is a good idea and it was the first solution that came to mind when I was having accidental wake-up issues. Tried it for a few days but stopped using it because it's awkward for me (camera bump irritates thigh) and it was un-intuitive to take out the phone, then turn it around in the hand to start using it. I just wasn't comfortable using it that way.
Like I said, this set-up works best for me, everyone might have their own way of doing things
All I know is that with this set-up, I don't have any more accidental wake-ups while the phone is in the pocket. That was the main requirement.

If you'd like to keep the tap to wake feature on, then the best solution for now appears to be what @aj7400 and @blackhawk have suggested - Keep the phone screen facing away from the thigh.

The screen of my phone frequently turns on when it is in my pocket and the phone starts performing some tasks like playing music.
Does anyone of you experience the same problem ? Is there any method to prevent accidental touches when the phone is locked ?
Edit: sorry I didn't notice this thread, so I created another one for the same problem. I'll try some of the solutions you proposed guys, hopefully it will fix the problem.

Was there any pattern to when Samsung's "accidental touch protection" failed to keep the phone screen inactive?
I'm trying to find out if there is anything going on that might affect the accidental touch protection. Normally, accidental touch protection keeps the phone screen off when the phone is in your pocket, to protect against unwanted touches or "butt dialing."
But in my case, my leg was a little sweaty and the phone screen activated and deleted some of my important info.
Has anyone else seen anything in terms of a pattern when your accidental touch protection fails to protect against accidental touches?
Maybe you had see-through pants with white pockets with direct sunlight glistening off your sweaty thighs?

Nope. Happened to me in Dark blue denims as well as black trousers.
It's not consistent. Works most of the time but fails every once in a while.
For me, usually I become aware of it when i hear the dialer beeps (somehow the screen taps end up on the emergency call dialer screen) go to town.

Funnily enough, I turned the feature off and was roaming around the city for more than 2 hours. No accidental wake-ups at all. This is even after I have temporarily restored double tap to wake screen. Need to watch this for a few more days and if i don't get any more ghost wake-ups, i'm keeping it turned off.

Turned off Accidental Touch Protection

Have you also tried just initiating LOCKDOWN MODE via the power button before a run?
I'm guessing that your leg and the sweat and the fabric combine to give the electric feel of a skin's surface that activates the phone?
You could also use a Bixby Routine to disable double-tap to wake?

Let us know your conclusion...I went the EXACT ane route (before finding this post): disable ATP and created a routine button to disable double tap to wake when I take the phone out for a walk.
Seems to be working, but it's another source of frustration as my previous Huawei mate 20 pro had the ATP feature but never started playing muzak in my pocket.
Samsung...good hardware plagued by half-baked software.

The Huawei mate 20 has much more major issues than our SK allies flagship phones do in more ways than one
I don't have these issues on the 10+ unless a put the phone facing my leg on the display side.
You should have a good case that has side protectors slightly higher than the display plus end display protection in the case ie Zizo Bolt case. Otherwise a face plant can easily destroy the display. These phones need case protection... before they kiss the concrete.
This also help stop accidental touches both when on and off. It makes the phone easier to hold and use as well.
Face the display away from your body. That should be more than enough...
If it's really still a problem limit display timeout to 1 minute.
Use only the power button or volume control buttons to activate the phone.
-or-
Use a case clip holster.

Well, in conclusion I can only say that the setup is working... Haven't changed anything since then and no accidental pocket mishaps yet. ATP and Double tap to wake are still off.
BTW, your idea of a Bixby routine trigger to disable double tap when heading out to walk is quite neat
