The Redmi 9 is one of the cheapest Xiaomi phones, which we can find on portals such as Amazon around 140 euros. But because it is cheaper, it does not mean that it has to have more or less problems than more expensive smartphones. High-end or entry-level, on our site we continually see how no mobile on the market escapes from suffering different types of problems. For this reason, we are going to take a look at the most common problems suffered by the Redmi 9 and their possible solutions.
It is not necessary to reach too high price levels, to find balanced and complete options like the Redmi 9. The hardware requirements of each mobile can be very different, and therefore, the problems can appear in very different ways, despite counting with the same operating system or even processor. In the case of the Redmi 9, it has just been updated to MIUI 12 and Android 10, although however modest it may be, it has been chosen by Xiaomi to be updated to Android 11.
Faults and problems on the Redmi 9
Many of the users who report problems with the Redmi 9, go to the official forums of Xiaomi to try to seek the support of other owners of the device. So let’s take a look at all those problems, and the solutions that have worked the best.
The screen does not rotate
One of the problems with the Redmi 9 has to do with the ability to rotate the screen when applications are opened. This problem requires that the mobile has to be restarted every so often so that they can be enjoyed horizontally.
Solution: The solution in this case is to delete the cache of the System Launcher , which can be found in Settings / Applications. In addition, we will also have to clear the cache of the affected games or applications and restart the mobile. Ultimately, and if all else fails, we can make use of a screen rotation tool.
Performance issue
The Redmi 9 is a modest terminal in terms of its hardware. The more modest variant, i.e. the one with 3GB of RAM and 32GB of internal storage, may experience performance issues. The user experiencing these problems notices a general slowness throughout the system, such as when opening applications or playing certain games. The problem is that the terminal can quickly run out of internal memory or RAM resources to run applications in the background.
Solution: In this case, the solution is to keep the terminal as up to date as possible. That is, we will have to free memory, deleting unwanted applications, close the background tasks to free RAM and restart the device at least once a day to free the cache. By doing so, we will notice an improvement in performance, which should not be neglected the internal memory available and the apps open in the background.
Problem with SIM not activated
Some users of the Redmi 9 report that the activation of the SIM card does not occur correctly. However, the solution goes through a simple method and is common to many other terminals.
Solution : click on the notification that appears in the upper panel. A verification message will be sent to register the SIM card. If it doesn’t work, we restart the mobile and repeat the process.
Touch screen problem
Although it should not be the usual thing, some users have problems with the touch screen as soon as the device is released. In some cases, when turning on the terminal for the first time, the Redmi 9 does not respond and it is not possible to advance in the first configuration screen. In this case we find two possible solutions:
- Solution 1: remove the plastic from the screen and the initial protector. In addition, we will remove any third-party covers or protectors that we may have put on before releasing the mobile.
- Solution 2: keep the power button pressed for at least 10 seconds until the mobile restarts. When you turn on the mobile touch it will work correctly.
WhatsApp problems
This problem has to do with the photos that are taken within WhatsApp. When seen in the gallery, they appear crooked on some occasions with a strange color.
Solution: go to Settings / Applications / WhatsApp and clear the application cache. Verify that WhatsApp does not have any filter activated. Then we restarted the mobile and the problem should have disappeared.
Problem with “Lift to wake”
There are many users who report that the mobile screen turns on by itself when moving it. This makes the battery drain faster and there are users looking for a solution. This is not really a problem, but it is a function that sometimes does not work correctly.
Solution: we will have to enter the Lock screen Settings and deactivate the “Lift to activate” function. The problem is that many users have it disabled and the same thing continues to happen. So we must reactivate the function, confirm and deactivate it again. Then we restart the mobile and test if the problem has disappeared.
Camera issues
Another of the most common failures is having problems with the camera, such as the native application not appearing or the message “No system camera found” is displayed. In this case we have several solutions to make it work as before
- Solution 1: enter Settings / Applications / Camera and click on clear data and cache. Then we restart the mobile and test if the problem has disappeared.
- Solution 2: If it is activated, deactivate Parental Control from Settings / Digital Wellbeing and Parental Control and try again.
- Solution 3: if the above does not work, we will have to download the official Xiaomi camera apk application again. We can do it from this link.
