[FIX] Proximity sensor on Redmi Note 7 and Note 7 Pro (NEEDS ROOT)

[mr_techno]

1) Install File Explorer Root Browser
2) Go to System folder
3) Scroll all the way down and opet build.prop file
4) Add these 2 lines at the end of the file:

ro.lge.proximity.delay = 150
mot.proximity.delay = 150

5) Save the file
6) Reboot

is this a permanent fix or what?
and how did u figure it out?
thx by the way

 

[mr_techno]

It should be permanent. Waiting to see will it stay fixed after rom update tho.
I did a lot of research, tried some apps but it did not work, and finally found this fix on some chinese forum.

Delay is already set at 200 in build.prop. I doubt just changing the delay fixes much.
Keep us posted on the fix…ya never know

Well I did not have delay in my build.prop (using pixel experience plus rom) and so far, no more issues with the sensor. Maybe try and change it to 150? What rom are you using?

PE 10.
AFAIK the instable proximity sensor issue is due to a poor driver released in a Xiaomi firmware, nothing so easy to solve.

Just registered to say my formerly non-operational proximity sensor now works perfectly (Pixel Experience)! Thanks very much.

if this fix doesnt work and youve tried all kinds of "fixes" you may want to check out this if you have previously changed the screen or frame or had any hardware repair done to your xiaomi redmi note 7, there may be small peices you forgot to install. https://forum.xda-developers.com/redmi-note-7/how-to/fix-xiaomi-redmi-note-7-proximity-t4008965

Did it, seems that solved my problem to hear whatsapp audios outside in the sun. Ty

For now works like a charm in MIUI 11.0.3.0 Global, thanks.

:good:

Just want to say thanks for this fix. Works with PE10 with latest Delta update. For those who don't want root can uninstall magisk after editing build prop no problem at all

CR Droid 6.2 12JAN release. Nothing has changed unfortunately with this trick :crying:

 

[abidalishakir.khan]

[AmulyaX]

Well, this can be included for sure, if y'all can let me know this actually works, I'd add the prop to the device tree. Thanks!
