Proximity Sensor Issue in Miui and CM roms !!!

Hi All
Any one facing proximity issues here , i saw so many peoples reported in mi forums that when we make a call screen blacks out when we moved to ears( Thats normal) and won't turn back again , so i have to wait the other side person to hangup the call or screen won't turn on power button does work that time, i think this only affects with Sensortek stk3x1x sensor, Redmi note 3 pro comes with two proximity sensors one is from Liteon and other is Sensortek.... Liteon sensors doesn't have this issue, for temporary fix "Wipe proximity area with a cloth or reboot fixes this and it comes back after sometime....( Calibrated but same it works for sometime) no idea wats causing this , issues there in Miui and CM roms....
I found sometimes a flip case with a magnet can cause issues like this when folded right back against the back of the phone, the screen won't come back on because it thinks the flip case is closed.

yeah but i don't have flipcase, this sensor issues starts with those have "Sensortek Proximity Sensor" Liteon doesn't have issue i think....
Flash the rom again using mi flash tool u will find that yr issue will be solved
Or go to test mode amd calibrate the sensor... that's all
Fastboot flash persist persist.img from latest miui rom? I recently had a problem with sensors. The above cured all
@Hemphiz i think that method for dead sensors bro, this one working sometimes it doesn't mostly if we flash a new rom and use no issues but if we reboot the phone after sometime issue starts.... @ra.one i did that bro flashmiui and recalibrate sensor but that works for temporary please check which sensors you got from this app from playstore https://play.google.com/store/apps/details?id=imoblife.androidsensorbox
if you got Liteon Sensors mostly no issues with proximity, if u got Sensortek u will be having issues or once u got issue it will come back..... im not sure why is causing that..... this is really very annoying bug.... Thousands of people reported in Mi forums about these proximity issues on various devices even on newly launched Redmi 3s/ prime may be they have all got "Sensortek Proximity Sensors".......
This is not a bug, You can disable Prevent Pocket dials under Settings-->Lock screen-->Prevent pocket dials...
I had this since last miui 6.9.9 flash.
Disabled prevent Pocket dials and All is working fine
Edit: for a few hours it was working.
Now its the same again. Phone blacked Out After a call and wont turn on, After a few seconds its coming back. As i said , since flashing new 6.9.9

like i said it may be mostly an issue with Sensortek proximity, can u check which sensors u got from this app https://play.google.com/store/apps/d...droidsensorbox
I have sensortec.
But i think its Software related.
Its since last Update.
I calibrate the Sensor and the issue with calls is still there.
Sensor Works fine, test is okay.

Yes i think its software related but, one trick works clean flash the same rom and use it for a week without any reboot...... (DO CLEAN FLASH and Dont reboot the phone)
don't need to calibrate.... for me when i install new rom and use it for a week no issues , if i reboot the phone the issue starts after sometimes.... i don't knw wats causing it so many peoples with sensortek having issues and this bug is not resolved from Miui 7 to Now Miui 8 MM, the issue there in Custom roms im using RR rom i have issues....
Guys For those having issues Check which sensor you got from this app, if u have proximity issues while calling its mostly "Sensortek"

We need Permanent fix....
I also have exact same issue and i have sensortek sensor. But i can unlock the screen while on a call by pressing power button and then unlocking with fingerprint. Bit annoying

So its confirmed its an issue with Sensortek Sensor, no Liteon users reported here, like i told flash the same rom which you are in (clean flash) and don't reboot phone for a week there will be no issues it works perfectly, if u reboot a phone once the issue starts again after sometime so after reboot something is going on no idea what....
i am using this app(for rooted users) on official RR and it works fine

even me used, but i don't think its properly working..... this issue starts only after a reboot, when u flash new roms and after boot dont reboot or power off the phone for a week, not needed any apps, proximity will work properly but once u rebooted issue starts....
But this app's settings load every time phone boots up.so it will work after every boot.
press thanks if I helped u in any way

yes this app i tested earlier, but after sometimes may be in a day or two it won't work....
Found another related issue with proximity , i think proximity is not working properly when there is not enough light around us something related with ambient light sensor i think ..... Eg: if we are in a dark room proximity won't work correctly turn on the light and try it works properly.... i think Xiaomi messed up with something with both sensors Liteon and Sensortek thats why Liteon users face Gyroscope lag in games in dark room and now i think may be the same reason why proximity not working properly in dark room....
hello. I have the BUG but my phone has sensortek version 1 (not 2)
When in a call the screen wont turn off when placing the phone at my ears. With whatsapp the bug wont happend.
I think this is a BUG related to sensor + phone app
A functional workarround is to dial, then press menu (putting the call at background) and then putting the call at foreground again. It works 100% of the time.
Any news? I have this annoying problem too!

Fingerprint not working

Hi All
My fingerprint worker for about 1 week and then it stopped working. I had stock build 15s installed.
Now i installed Cuoco's build which is based on 17s but i still have the problem that i am not able to add or use fingerprint
Is this a software or hardware issue?
Fingerprints were defects. I think you will send to warranty or use it without fingerprints.

Fingerprint sensor problem

My MediaPad M5 (SHT-W09) has worked up well until yesterday. Now the fingerprint sensor is not working. I have rebooted, turned off & restarted it. I think the sensor MAy have worked again for a very short way but it is definitely does not work now.
The sensor does not work at logon, does not work for my banking apps and is not seen by other apps.Some apps say that there is no fingerprint sensor.
Has an app or something captured the sensor? If so how do I determine what is "hogging" the sensor?
Or is the sensor no longer working? Is so, is there any way to fix it?
Chris
Has anyone had the fingerprint sensor fail?
Chris
I also have the exact same problem.
It began a couple of months ago. The fingerprint sensor would show up for a couple of minutes after a reboot, but now it has disappeared permanently. Even the settings app won't show it after a restart.
Have you found a solution or some insights that could help us debug this?
I tried clearing the cache and sometimes it works for a while then the problem would reoccur. I did a reset to factory and this fixed the problem for a while.
I did cut back the number of apps.
Now it works perfectly and I don't know what caused the issue! It may have been a stray app.
Sorry about not giving a definite answer.
Chris
I have the mediapad m5 lite and I am having the same problem. It was complaining that the fingerprint hardware wasn't working and I restarted and now it is unaware it exists, even in settings. What was the cache you cleared? Did you have any luck further discovering what the cause is?
The fingerprint sensor works well now.
As I said previously, it must have been an app but I have no idea what
Sorry
Stay safe

Redmi note 9 pro raise to wake stopped working.

At first I thought it was because my gyroscope sensor stopped working. But I tested it with an app and it works fine. So it must be some software issue. Does anyone know how to fix this?

Hello, have you resolved the raise to wake issue? My problem is similar, my redmi note 9 pro on android 11 stock launcher has the raise to wake feature that stops working every 5 days, meaning every 5 days I reboot phone for the feature to work, then after 5 days it seases to work and I have to reboot phone again for it to work and so on.
Any idea what could be the issue? Gyroscope is working fine as well as accelerometer.
Appreciate any help, i haven't rooted the phone yet, so cannot do much from shell termux...
Regards
