With the arrival of new smartphones in the Xiaomi mid-range, such as the Redmi Note 9, Redmi Note 9S and Redmi Note 9 Pro we had the opportunity to meet a series of devices with much to offer and also much to polish. Previously we already managed to solve the first failures and problems of the Xiaomi Redmi Note 9 but the truth is that they have been repeated.
All of them have received updates that to a greater or lesser extent have solved some of the problems, while in other cases instead of fixing them they have made them go further. Most of the performance, display and connection related inconveniences have a relatively simple solution that we can implement ourselves with the help of MIUI 11, the latest version of the Xiaomi layer.
Proximity sensor issues
These are not the first Xiaomi mobiles to face this problem, previously we have also seen how when making calls sometimes the proximity sensor does not work as it should and we are forced to think of solutions. In this case, the Redmi Note 9 are the most affected since a message appears on the screen as if we were continuously covering the sensor.
Luckily the solution is simple, basically, we have to go to Settings> Lock screen and choose pocket mode to disable it. This should fix it until in the next update the firm finishes correcting it and we do not have to resort to other solutions for the Xiaomi proximity sensor.
Some applications are closed continuously
One of the errors of the Redmi Note 9 that more problems is giving is the unexpected closure of some applications. A problem that appears from previous versions of Android is very present in some users and prevents it from being used normally. For now, it has not been possible to find a solution that works for all users and the only thing we have left until it is fixed is to resort to the Xiaomi cleaner.
Within the security application, we have the cleaner and the speed increase that allows us to keep the RAM memory up to date so that these failures are not repeated.
WiFi connection is lost
In the MIUI forums, we have also seen problems with the WiFi connection that affect the message options. If we do not have mobile data activated, it is likely that we will stop receiving messages because the WiFi connection stops working. This problem is already being tried to solve so that it does not get older.
Manually we can try to fix it by entering WiFi> WiFi Assistant> Traffic mode and we will choose the normal mode. In the previous tab we must also try to enter the best networks automatically and disable the option so that it does not disconnect alone.
Errors to be corrected before MIUI 12
The large number of failures that are present in the three Xiaomi Redmi Note 9 models worries users, although many of them are more aware of the arrival of MIUI 12. By the company, they are aware of all of them through the forum and of course, you should fix them as soon as possible so that they are no longer complicated with MIUI 12.
A joint MIUI 12 update dragging these bugs could mean forcing users to perform a hard reset so that the errors are no longer present and further complicate their existence. We hope that by the time the latest version of MIUI reaches these models, all will be resolved.
