New updates are being added at the bottom of this story…

Original story (published on May 15, 2021) follows:

There has been a bunch of reports from users of the Xiaomi Redmi Note 10 Pro, Poco X3 NFC, and Poco F3 about proximity sensor issues. Kind of odd to see several devices affected by the same hardware-related bug.

For the uninitiated, proximity sensors are what that help turn off your screen when you keep your phone close to your ear when taking calls. This is done with the use of an infrared LED and an IR light detector.

The advantage of this is extended battery life during calls, not to mention prevention of accidental touches so that your ear does not open some random music video on YouTube while you’re on call, much to the surprise of the one at the other end of the line.


Proximity sensor on RN10 Pro global: The proximity sensor sometimes does not work. Here is a test I did in which I put my hand on the phone in intervals but sometimes the light turned on and sometimes it does not. The light should turn off when the hand is on the phone.

@POCOSupport Hello I have poco X3 device and after doing April update it has some issues with proximity sensor when I am on call. Need your help. How can I resolve it? Tell ASAP

As clear from the above complaints, users of the Xiaomi Redmi Note 10 Pro, Poco X3 NFC, and Poco F3 are encountering some serious proximity sensor-related issues.

This includes the display lighting up continually during calls or the proximity sensor not working at all causing the display to be lit for the entirety of a call session. Pretty annoying to say the least.

Xiaomi Redmi Note 10 Pro

While we do believe that these issues are one of those that arise due to the software being a little rough around the edges since it’s new, it does not seem entirely true.

This is due to the fact that while the Redmi Note 10 Pro and Poco F3 may be recent releases, the Poco X3 NFC is obviously not, being launched over half a year ago.

Either way, the proximity sensor problems are all set to be annihilated as Xiaomi has revealed with their recently published MIUI Weekly Bug Report that they’re working on fixes. The company even gave out the ‘root causes’:

And as for the Poco F3, a community moderator has stated that the fixes for the proximity sensor issues have been merged into the next stable update and should hence roll out soon.

AFAIK, Touch issue exist in some 3rd party app, which is being analyzed. P-Sensor, Screen Dimming patch is merged into next Poco F3 stable Update which will fix it. Stay tuned!

So all you need to do now is sit tight and wait.

Update 1 (June 26)

11:49 am (IST): The Xiaomi Mi 11 Lite is yet another addition to the list of devices affected by proximity sensor issues. Thankfully, an acknowledgment for the same has been given.

Update 2 (August 23)

05:20 pm (IST): Xiaomi has allegedly ended its deal with Elliptic Labs – the OEM’s supplier for the software that drives proximity sensing, and instead struck a deal with Minghao Sensing. It’s unclear when the new solution will be making it to Xiaomi devices though.
