Xiaomi, a Chinese smartphone manufacturer, is a hugely popular smartphone brand which has established a stronghold in Indian and Chinese markets among others. Its flagship series Redmi and Note smartphones have taken the world by storm. Its smartphone wiz Redmi 5, Redmi Note 5, Redmi Note 4, Redmi Note 4A, Redmi 4, Redmi Note 4A are just a few of the eccentric and widely popular smartphones currently available at a staggeringly affordable price. But it not all sunlight for the smartphone users as recently, many users have asserted common complaints regarding poor proximity sensor performance.

We curated all the comments regarding users’ claims about the poor proximity sensor performance which has been common for all Xiaomi users irrespective of models which is a big problem to tackle. The proximity sensor is an important sensor which prevents accidentally disconnecting the calls or pressing any button while on a call since the sensor disables the screen when the user interferes with the sensor. It is like when the user holds the phone at a length, it doesn’t activate, however, when the user calls someone, the screen will automatically turn off temporarily that disables assessing any feature like mute, hold, add another caller accidentally.

But turns out, it is a common problem in most of the Xiaomi smartphones since a lot of people commented and complained about it on this website as well as a bunch of other websites and forums. Don’t worry, GetDroidTips is happy to help since we have compiled an explicit list of troubleshooting tweaks and tips that would kickstart the sensor and induce it to start working properly.

Restart the phone

This seems to work for almost every minor software glitch or minor issues and that is why it is one of the easiest and most recommended methods to fix any sort of software-related issue which includes fixing poor proximity sensor performance. So, simply press the power button and reboot the device. This will erase the cache, temporary files and registry as well as free up most of the clogged and hoarded resources on your phone. But the catch is, it is just a temporary solution. In order to keep the component up and running properly, you’ll need to frequently reboot the system. I recommend a reboot once a day as a part of the temporary solution.

Update the firmware

Outdated firmware can cause the proximity sensor to perform inferiorly. This is why you need to update the MIUI in your Xiaomi smartphone and Android operating system in other smartphone brands which can also introduce bugs to lower its performance as well. Thus, simply update the firmware by following the procedure mentioned below.

  • First, go to Settings and proceed to About Phone section.
  • Next, tap on Software Update or Updates and search for the available updates.
  • In case the update is available, download the file to install it on your system.
  • The process could take several minutes to complete.

Troubleshoot the Proximity Sensor

If you are having a poor proximity sensor performance issue, it will be handy to check if it’s faulty or not. There is a hidden feature embedded in your Xiaomi devices which lets the user check the various components which include proximity sensors too.

  • You need to type in ‘##64663##’ in the dialer app on your phone.
  • Next, a list will appear on the screen where you need to search for the proximity sensor.
  • Now, place the finger on the sensor to check if there is any reception or not.
  • The test results will come fails if it is faulty.
  • This is where you need to report the issue to the service center.

Perform a hard reset

This is the last resort where all the data ever saved on your system will be deleted once-and-for-all will have the tendency to fix various software glitches too.

  • Switch off the phone.
  • Press power button, volume up/down button and proceed to the recovery mode.
  • Scroll and tap on ‘wipe data/factory reset’ and then, select ‘Yes – delete all user data’ to initiate the hard reset.
