Although MIUI already had to be practically mature, there are still many users who encounter problems, since little by little the new updates are reaching new users. The last ones that have appeared have to do with the screen brightness in MIUI 12, leaving Xiaomi, Redmi and Poco mobile users affected.
However, it is not the only version of the Chinese customization layer that has been dragging different problems with the mobile screen looking dark or always having the brightness at its maximum and not being able to adjust it. There are several devices that have encountered these errors after updating their phone to a later version. We have known this through the Xiaomi, Reddit and social network forums, from where users have explained their errors, which change and, therefore, also the solution. Although do not be discouraged, because the way to fix it may be faster than you imagine.
Most common problems
Now we are going to see the two main errors that are repeated the most in Chinese mobiles . Although with the passage of MIUI updates there are many improvements and new features that have been integrated into Xiaomi, Redmi and POCO mobiles, the truth is that the bugs are also more present than ever.
It can not be changed
One of the errors that has caused the most confusion and that has been repeated on more devices is the one that has to do with the manual control of the screen brightness . Apparently, the renewed control center that MIUI 12 offers is not polished in all terminals and users have been left with the fact that they cannot move the brightness bar when the panel is fully deployed.
Auto brightness goes crazy
The bug with the brightness of the mobile screen in MIUI 12 has caused many to complain through Twitter about problems, where the brightness level drops inexplicably even though we are in broad daylight. They have also complained that the brightness control changes quickly when we are at home, causing it to constantly go down and up, which can make it very difficult to use the mobile panel.
How do I fix it?
Unfortunately, these bugs with screen brightness in MIUI 12 may be a bit more complex. Although, we will tell you the different ways to solve it as soon as possible.
Activate day mode
We can choose to access Settings> Display> Brightness level and remove the automatic brightness to replace it with the MIUI daytime mode, which improves the brightness behavior when it is daytime based on ambient light and can be a good way to replace it without complication.
Although, this solution may work for you, so we will tell you how to find the best way to fix the screen is too black or the other way around, fully lit all the time.
Get to modify the brightness
In this case, there is not only one solution, but there are several depending on what we prefer. The first and easiest thing is that the control center does allow you to move the brightness manually if you don’t slide it completely. The second thing is to remove the new control center in MIUI 13 to return to the classic, which does not cause this type of failure and will also give us easier access.
Test the sensor
However, in case the problem continues anyway and the update never managed to improve it, we will have to check that the light sensor is working properly. We will do this with the app from the Play Store called MultiTool Sensors that offers us a graph in which we can check if when placing the mobile in the dark and in front of a light, it detects the light variation, since it could be the error and not the software. Therefore, here we leave you the following link so that you can try this app on your Chinese mobile:
Don’t use screen protector
There are also errors that increase or decrease the light of the display. Here the sensor comes into play again, the one in charge of ensuring that the brightness of the screen on Xiaomi smartphones works correctly. However, in mid-range and entry-level phones it does not exist as such. This uses software-based options and we can only remember not to use a screen protector to avoid this chaos with the dark or light panel of the device.
Update your Xiaomi
There will be many times in which we have seen this error repeated in countless Samsung, Huawei or Xiaomi smartphones, just as we are seeing now. However, its solution is also repeated, since we have found that the failures related to the light sensor were due to a software bug, in this case, the problem comes from MIUI 12.
This has a simple solution through an operating system update, so the first thing we have to do is go to Settings on our mobile> About the phone> Click on the MIUI version option> Check for updates . Hopefully, the Chinese manufacturer will have released a patch that puts an end to the repeated failure with the brightness of the Xiaomi, Redmi or POCO mobile screen.
format the phone
In case the sensor does vary, we will have to think about the software error that most users seem to be suffering from and which is only solved by formatting the mobile with MIUI. A process that will erase all the data on the mobile and therefore we have to put our files safe first. We will do this by going to Settings> About phone> Factory reset > choose the option to delete all data. In this way, we will return to the original version of the terminal’s operating system, so we will say goodbye to the bugs that this new version of Xiaomi’s customization layer is causing us.
