Hi All,
There is some hardware issue with my S4 that it will wake itself up randomly every few seconds. It has this issue with every touchwiz rom I put on, Kitkat or Lollipop (fresh install so that I know it's not caused by some apps installed later). I'm sure I have tried everything like disabling air gesture, every senor related function that I'm aware of.
I used wakelock trying to track which apps triggered the wake with no luck.
I also tried gravity screen, no luck.
The only fix so far is using a cm rom. I suppose it's because cm rom ignores some sensor info compared to touchwiz. I can stay with cm but I really like the stock camera.
Can anyone cast some light on how to fix this screen wake up issue on touchwiz?
Update: Finally got this fixed. The fix is very specific to this phone. As I mentioned this phone has some issue including home key not working and the random screen wake. After disable home key mapping in Generic.kl and gpio-keys.kl by adding # in front of key 172 Home, screen wont wake up by itself again.

Hi
I've been having the same problems with my phone, I think I've managed to fix the problem,
I went to settings, device, display, then at the bottom turn off 'ambient display'
Problem seems to be gone
Hi.
I have problem with proximity sensor. While making a phone call, display is always on.
I tried to enable it in settings. Turned it on, rebooted my phone and nothing happened.
Also tried *#*#6484#*#* solution, and when I open proximity sensor, there are 'test' and 'error' buttons on the screen and I can't click anything.
Does anyone know how to fix this?
In the engineering menu * # * # 6484 # * # * we find 27 - Proximity sensor
When approaching the palm to the front camera should show "0".
I always showed "5", did not want to be calibrated.
I pressed Error, went out and went to the engineering menu, a miracle happened - it was calibrated.

No, nothing happened. As usuall, screen is always on.
Yes, proximity sensor in settings was on and I have rebooted the phone.
I really don't know what to do. Is it because of bug in Global Rom or is it hardware malfunction?

Hold your phone with your left hand. The placement sensor gets blocked by your right ear when you make calls using your right hand. Give it a go and get back to us.

Ok, non-related to left and right hand.. Now my phone gets black screen all the time during calls. I can't put it on speaker or do anything while talking with someone. I really don't know what's happening...

I can't help there but left/right holding is an issue I guess with this phone. Or maybe it's the Pro. I forget offhand.

Obviously the proximity sensor is at fault. Enter the menu using the code mentioned above, then press the menu/options button and select Calibrate proximity sensor. Once you're there, hold your hand over the proximity sensor (to the right of the front camera) and tap the Calibrate button. That's one thing that could fix it.
Failing that, go to incoming call settings and turn off the proximity sensor (turn off screen in call). Restart your phone, go to the same toggle and turn it on.
If neither of these works, you likely have a faulty piece of hardware. Your last option is to have the phone repaired or try a different kernel/ROM.

Hi , are you on miui global stock rom? Or custom rom?
I just had the same issue , but in my case , I recently opened the bootloader and installed xiaomi.eu rom, everything was working fine. I got notification of update ,I downloaded the update , but flash it thru TWRP , and then with the new update, the proximity was not working at all. Flash again the new rom, but wiping everything , and now works.

Is the EU rom that better?
I mean is there any plane to compare the known issues between the global and EU ?
I'm using the miui global 10.3.3.0 PFGEUXM and definitely have some "issues" with the proximity sensor.
I'm still trying to tie down the exact nature of the problem:
With a quick test, or doing calibration, it seems to work exactly as I would expect; the screen switches off as you approach closer than about 2 inches.
However during a long call I notice the display start to flash "on" frequently in the corner of my eye and soft keys can get inadvertently pressed.
It kinda feels like it gets worse during the call, is it time or perhaps the phone warming up in my hand? Not sure.
hi @All!
is there still no permanent solution for fixing proximity bug?
its really annoying and making me crazy....
even after making it working again using quicktune app - doing one call it is broken again

Exactly what i've experienced.
Super annoying when you accidentally hang up during a call.
It happend countless times so far.
I'm on eu beta btw.
Wish there would be a solution.. . But afaik proximity is even more bugged in non miui custom roms.
I had this problem to. my proximity sensor what not responding at all. I thought it was defective because the calibration was not working to.
Then i went to the system update settings, downloaded the latest package and flashed it. After reflashing it started working with no problem at all.
Factory reset did the trick for me. Working normally now.
Install Quick Tuneup. Then do Sensor Celebration & Restart your device twice.
Two solutions

It turns out that the problem is because MIUI does not activate the proximity sensor when the smartphone is turning on.
To force MIUI to ALWAYS activate the sensor at each start, we can do two things:
1- Always have "Automatic brightness" activated
2- Activate the "Pocket mode" (the best choice)
After applying one of these situations, it is necessary to restart the phone.
Only by activating the pocket mode it is no longer necessary to have automatic brightness activated all the time.
In the video I show how to activate the "pocket mode"

I published this solution in a forum in my country (Colombia).

above is proof to SOLVE the Proximity Sensor no reaction in my Redmi Note 7.
I was having lots of TASKER Profile depending on whether or not Proximity Sensor is covered.
I found all those Profiles no more function due to the issue after I believe OTA to Global rom the latest ( August-2019 )
Thanks again to KMILO_PARRA

Actually, the proximity sensor for Redmi Note 7 isn't in the "usual" top-center position, it's a little bit on the top-right edge (if you watch the phone "against the light" you can actually see a small dot on that side).
If you're calling\responding try to put your ear at that angle, you'll never have those problem anymore.
I know it seems crazy, and of course the first times could be "unusual" to put the ear there, but it actually worked out flawlessly for me.

It works for me
Hi guys,
I have made a little workaround, using the suggestion of @KMILO_PARRA user. (pocket)
https://taskerprofilecenter.blogspot.com/2019/09/project-proximity-sensor-workaround-for.html
This is mainly for Tasker users, but I have generated an APK to be installed too. So any user can use it. But what is needed, by now, is root, as it needs to write to Settings table.
Please, report me back if it does the job or not.
Note1: For those users that don't know how Tasker works, just install the app, and give it root permissions, and allow Write System Settings permission (Android option). I recommend you to not set it as an app to be killed from the OS using the battery optimization, as it could be killed. It acts on every shutdown and device boot.
Note2: It will generate two permanent notifications: Place holder, and the one that is the mini-Tasker code monitor (required). Just, disable the Place holder one, as described in the same notification (click on it), and disable notifications completely for the installed app to get rid of the last one.

What it does exactly?
Well, as I explained on my web, it just changes the value (0/1) from the 'enable_screen_on_proximity_sensor' Global Settings table, that makes the pocket option to be toggleable in an automated way.
So, be sure not to use that option as a daily one, as the project/app uses it to allow the sensor be available at startup. And do not forget that you will need root too! Sorry.
What to download if I don't know what Tasker is?
You will only have to download the APK from the 'Kid App (APK)' link, provided under the 'DOWNLOAD' section. Nothing else.
If you know Tasker, you will know what to do.
Does it work really?
I'm currently testing this workaround, but as I could see, at least on my device (lavender too), seems to be working as expected. But needs to be tested a little more.
So, if it does not what it's intented for, please, report it me back.
After installing the app, giving root permissions, and allow it to modify system settings, reboot the device to take it effect.
