Question Rear screen problem - Xiaomi Mi 11 Ultra

Hi guyz,
I have a problem with rear display. Normaly, I set it to show display the time. But, it stops working completely after a while. Double tap is not working, either. Notification is not showing at all. Only camera app is working.
When I restart my phone, it start working again, but, stops again a few hours later. I disabled battery saver, set battery limitation to no restriction, updated to latest version but none of them helped.
I am on chinese rom 13.0.9
Rear display app ver 1.4.6
Any solution?

Simply update it to latest version, on global version we are on 1.4.7, so on china version you'll find high than that for sure.
Think link should help

Thank you for answer. I updated the latesr version (1.4.7). But, it didn't solved my problem, either.
Rear screen stops working for a while! But when I restart the phone, it start working again. I couldn't find a solution yet.

proximity sensor not working?

Hi All,
My proximity sensor isn't triggering during calls (Possilbly at all?) causing me to accidentally put people on hold.
(very annoying! at least make a tone so I know I hit the button)
Is there a switch for that?
What's weird is that I don't see a HW test for the proximity sensor in the diagnostics screen (tapping on kernel version)
Edit -> settings -> system apps -> phone -> incoming call settings -> proximity sensor is ON.
Can someone whose proximity sensor is working download a sensors test app like https://play.google.com/store/apps/details?id=com.wered.sensorsmultitool&hl=en
and tell me if that detects your proximity sensor distance correctly? (or whatever app you want, just tell me which one).
- Frank
Go to Settings - About phone and tap 5 times on Kernel tab. You will get into test menu. There you can to test and calibrate proximity sensor.

I don't see it. What is the test called?
What Rom are you running? I'm on 8.0.10.0
See pictures below. Test menu works on any firmware.

Just looked at mine and I have prox sensor as number 9. Sounds like you may need to flash an updated build.
I updated to developer rom and proximity appeared and was working.
I then re-updated to stable rom (8.0.12.0 i.e latest) and it dissapeared again!

You already have the answer you're looking for. Guess the sensor is broken in the stable build. In this case, you may have to wait for the next stable release or use an alternate ROM.

Confirm proximity sensor missing in 8.0.12.0
Unfortunately, it is also missing in 8.2.1.0 stable
On Chinese 8.2.3.0 and the settings are missing from the CIT list also ... with that said I don't depend on it anyways lol. Just checking things.
for some thick case the proximity sensors might have problem... need to reboot phone with case on to "register" the case thickness...
hi mi mix fans , I came through lot of applications,proximity sensor tests, procedures, secret codes etc . to get solution for "screen off during call and not on automatically" but i found the real solution in this is .. remove back cover which almost users use . , tpu transparent also and see whether it work during call ..yes,finally got solution. check yourself all test works properly and screen on during call when device is away from ear..if not ?? pls consider to clean sensor ..
Wanted to test it. I can see the test, but not sure how to test it. I still don't.
So I tried to the front microphone test to learn how to use these tests...
But it scared the s**! out of me. It's such a haunting noise! Is that normal?!
I'm on global stable, CIT proximity option doesn't show too. I think my sensor is bugged by my cover since when the device isn't covered the sensor works fine.

Yes, such an annoying noise.
i have same problem i just updated phone after proximity sensor not work why xiaomi not try before update this f*cking fw.

What I observed is after resetting when I tested it I came to know that sensors sensitivity distance increase up to an inch but starts dropping again as I move object in front of sensor 8 to 10 times and is reduce to 1 cm finally which is very less if you hold mobile in left hand ear but it works on right hand ear as proximity sensor is placed left of mobiles front side.I think it is a software problem which xiaomi should look in to.Sensor keeps on calibrating till it reduces distance to 1cm from nearly 1 inch that is 3 cms.This is very shameful for xiaomi that after so many years of experience they have not yet resolved this for Mi A1.
My proximity sensor also isn't working. I've tried to do this test we find on kernel tab, but I couldn't test it, it shows no options for me to calibrate or sth. Help me please!!
Same issue here. Phone just turns black, when I am calling people - difficulties to restart the display afterwards. Using Lineageos 16 - no chance to tab the kernel there. Dialing * # * # 64663 # * # * shows no results. Wandering, if this is a hardware or a software issue.

Rear Camera and Flash not working. (Possible Camera Firmware problem)

Ok, the rear camera doesn't open. I can't switch to it in the camera app or snapchat etc. Flash doesn't work either, and if I do the "V" gesture for flash when the phone is locked, it restarts. I have:
* Cleared cache/data
* Disabled and re-enabled the app.
* Dirty flashed OOS 4.1.7 multiple times and have also flashed Franko's Kernel which I normally use (currently running stock kernel though).
* Google camera app multiple times. (had this before too, then I deleted it after this camera problem arose)
Not sure if relevant but TWRP has been giving me some error I haven't been able to fix for some time, and can't delete the file that it says it can't open (through twrp itself or cmd+adb) . Relevant SS attached.
Thanks.
You may want to try to flash the phone using the unbrick tutorial. Make sure you have a backup of internal memory
Hmm, I haven't tried that. I just did a clean install with no success. I deleted everything except USB OTG from TWRP. This has become much harder to fix than it should be . I didn't even do anything to set it off, I was in snapchat and took a pic and then it stopped and the rear camera/flash haven't worked since.
Just to update, I just tried a clean install of NLOS Lineage OS and the rear camera/flash still didn't work. Also, if I try to take any type of video with front camera the phone says "Low memory, adjust the picture resolution or delete some files" even though there's only 3.3 GB of space used.
Also, after a clean flash and wipe of everything the error reported by TWRP no longer exists. So that wasn't what was causing the problem.
Just used the unbrick tutorial. It worked perfectly however the problem still persists and remains unchanged. Anyone have any other ideas?
After some deep diving through forums I decided to use the phone's inbuilt hardware tests, in particular *#808#, as the camera test given by dialing *#*#34971539#*#* doesn't work. Firstly, the flash works through the hardware test (although quick settings still doesn't). The "foolproof camera test" gives BackCamera PASS and FrontCamera Fail. This makes sense as when I go to the individual tests the "backcamera" shows the front camera image, while the "frontcamera" just says "cannot open camera". The PDAF/Cam_EEPROM info test says "FAIL Qualcomm", which I believe is the camera firmware not working. The storage test says "sdcard is unavailable" which I assume is why the camera isn't allowing me to record any video through the selfie camera and says "Low memory".
In summary, how do I fix the camera firmware problem and the sd card error?
RMA your phone, hardware fault.
Ok Thanks.
So there is no way to update/fix the firmware problem?

Im having the same problem on my one plus 3...did u find any solutions??? if yes plz lemme know.
I haven't found a solution.i replaced both The front and back camera and even played with old/new cameras in different configuration (old front + new back / new front+old back / no front + new or old back and so on) varying the result from "Back camera pass/Front camera fail to both Fail ) .the funny thing Is that if you just remove back camera and do the diagnostic menu *#808# > foolproof camera test it still says back camera pass
I have the same problem... And my camera before of this beta worked awesome... Beta 24 **** our phones...
Experiencing the same problem with the front (away) facing camera and the flashlight.
Same Problem for me since the latest official Beta. Ich tried resetting and reflashing the Phone with the last official stable rom. Did not help.
I think I solved this. I let the phone cool down then i powered it off. I let it cool down a bit again and then booted it back up. The camera and FL work.
It seems that this happends when the phone gets heated, at least in my case.
I have the same problem, camera was working fine yesterday. Foolproof camera test shows front camera fail. But the front camera works

Issues encountered so far

Hi,
I am seriously considering returning this. Its so nearly great but my unit is suffering from the following:
1. Stuck on Android 8 and Feb update. See seperate thread.
2. Touch screen touch sensitivity has some real issues. Scrolling around will occasionally "jump" or reverse direction briefly. I see this a lot on cheaper Android devices.
3. The default notification sound is a ringtone that goes on for 20 seconds approx. I have to change this for every type of notification for every app.. Its maddening.
4. Camera is... meh. Good for the price, but a long way off the top tier.
5. Auto brightness isnt good. Changes too fast, too often. Its all over the place.
UPDATE! 6. Developer Options seem totally broken. Settings dont persist or they do and the UI doesn't remember selections. What a mess.
NOTE - there are lots of positives, but these are well covered elsewhere.
All in all... this feels like any other cheap-ish Android phone. Needs updates, and dont kid yourself that this is the bargain of the century. Its good value, but its clear where compromises have been made.
Lot of bluetooth issues with 8.1. Sound is lagging when paired to my Sony WH-1000XM2. Other devices might loose connection after a while and needing to be re-paired.

2. Is the touchscreen a software issue?
3. Surely there has to be a better way of dealing with this notification ringtone? - Anyone got any ideas?

For 3, I may have solved this myself - there is a default notification sound option which can be changed from the 20 (approx) seconds ringtone. I changed this and still got 1 of the long notifications, but the rest were normal.
As for 2), hopefully this is a software issue. The touch panel has a firmware version which is why I am so keen to get the 8.1 update (as it *may* have a newer version?) as mine is stuck on older software.
I have problems over several apps:
- Instagram no sound in stories
- Snapchat video quality is very very poor and pixilated
- Camera Zoom in Instagram, Snapchat and Whatsapp sometimes works and sometimes not.
- Stock Camera app, sometimes there are glitches when the camera is switching from wide to tele in lowlight.
- Playstore and Recent apps window sometimes lags
Anyone else experiencing those bugs?

I just checked your first 3 issues, I don't have any of them. I didn't notice any glitches with the camera either yet, but I haven't tested it that much. Only thing is the lag when switching between recent apps, Playstore works fine though. Maybe try and clear the cache of the apps you have problems with? Or maybe you didn't update them?

i just found out that my instagram audio is not working when i have my phone in vibration mode instead of ringing mode, although media volume is on max.
As soon as i change into ringing mode the sound in my instastories is working! Should be a software bug, but not sure if from instagram or nokia.
EDIT: are you able to do a smooth zooming in snapchat or only "1 step"? Because after reinstalling the app i was able to fully zoom in, exactly how i am used to it. Afterwards i started the stock camera app tapped the x2 button to zoom in. Then when i went back to snapchat i was only able to zoom "1 step" like i would press the x2 button in the camera app, instead of a continuous zoom.
My volume key temporary disabled after use instagram or some local apps. Uninstall TalkBack help me this. You guys who had trouble with sound should try.
I can agree to some of these issues.
The most annoying by far is the auto brightness. Sometimes when I unlock the phone it turns the brightness all the way down, even when I'm outside. Makes the screen all but unreadable. More interesting is that it makes the adjustment even though the auto-adjustment is turned off.
The bluetooth sound is choppy sometimes.
No complaints on the screen or the camera from me.

yeah, the auto brightness does not work as good as it should. Just had a 2 hours call with a bluetooth headset and everything was just fine! Maybe you could try a different protocol in the developer settings for bluetooth codec?
Hey everyone !
I received my N7P a few days ago and i noticed that everytime i record a video, this message pops up : "OZO audio is deactivated".
I live in France and this the European model.
Do you have the same problem ?
I noticed that they also removed the face unlock. Any news on that ?
Thanks for the support guys ! :good:

Hey, I am curious about how the WH-1000XM2 sounds in nokia 7 plus. Is it better or worse than your other devices except for the lag?
I'm in the UK, just the received the phone and am also stuck with the 8.0 + Feb security patch. It's saying I'm up to date.
Also, is anyone else's system storage taking up 14GB? Should it be that big? It's already using 22% before I've even installed an app. Tried a factory reset and same thing.

Screen Recording Slow Down (BUG)

Does anyone here know how to solve this problem?
When I'm going to do some screen recording and everything is slow!
Can anyone give me an advice?
Bought my Red Magic 3 12/256gb Global Rom.
For the first month it was okay until some bug appeared.
My bug was the recorder settings.
I can't record at all even if my record settings are ON. And it's always ON. I can't turn off my recorder.

Aod ?
toniq1 said:

Always on display. Sametimes it's help but it's probably fault of ambient light sensor or screen.
It is the same If aod Off
Not good
That's a common thing with faulty oled screens, it is a hardware issue
I have the same flashing screen when I turn the screen off before the aod is displayed. It does not happen all the time. Turning off aod does not help. I doubt that it is a hardware issue as the flashing started after updating to MIUI 11 - at least for me.
I have also this problem, started a while ago when I was on MIUI 10 after I installed some kind of dark theme
This indeed looks like a AOD fault cause turning it off solves the problem, and the latest version of AOD with custom picture customization, reduced this issue for me
But it also seems like it mostly happens when the ambient light is low so the automatic brightness reduces the screen light and AOD starts to flash
I hope it won't be a hardware problem
One other thing that I want to mention is sometimes it goes really bad and the screen starts flashing for a long time, in this case phone seems to become unresponsive as not touch and not the fingerprint sensor and infrared camera doesn't work at all

It is used for past time if you're asking
So a little update on the flashing screen situation
I disabled auto brightness and set the brightness a little below middle of brightness bar and so far so good. No flashing here for a while
Also disabling the AOD completely solves the problem
Another update on the state of this flashing issue, after Android 10 update haven't seen any flashing so far, AOD display works fine, light sensor and automatic brightness work just fine.
I guess it was a software issue after all
I hope you have solved it. Do you have the anti-flick on?

Nope I don't
Anyone else who has this issue:
Try disabling hardware overlays in developer options, also check to see if the Game driver option within Developer options is set to default. Although its possible that this could be the beginnings of a hardware issue, it could also be a software related issue.
If none of the things that I mentioned work, i would try reflashing the stock fastboot rom. ( must be fastboot version)
Similar happened to me but i think this is not recoverable.

You need to return to stock using a fastboot rom, using a recovery rom will not work.
Most likely you have corrupted files. but sure it could be an hardware issue, especially if you have dropped the phone or installed something to increase the refresh rate. If you flashed a refresh rate mod, then you need to flash the DBTO image from the fastboot stock rom.

I have TWRP installed and thought of checking it out but it simply flashes there as well. Right now i have the display on, set never sleep in Developer options and simply keeping it up until new phone arrives. Once i am on new phone, i will try factory reset on this first and go from there i think. Not sure how to get to fastboot when display is not working.
Due to such weird nature that nothing really helps i tend to think that this is HW issue.
EDIT : Turned off display by accident (because phone call happened) and now it's back to flashing disco with absolutely nothing working. Fastboot (power + lower volume key together) is of course flashing as well so inacessible.
Happened to me too. Turned off AoD, restarted, turned on and it was ok for a while. Now flashed again. Dont know what is causing this :/

I also got the same issue on my dipper. The only solution that works perfect is by flashing to LineageOS 17.1. I know it's an OLED screen faulty but Lineage really fixes it. Been using Lineage for a few months and never have this display issue again. Other custom ROMs can't fix this display issue.
