1 Insufficient storage space?
Before installing new software, please make sure that your mobile phone has enough storage space. There is not enough space, of course, the software can't fit in! Try to delete some unnecessary files or applications and "slim down" the phone!
2 The system version is too low?
The mobile phone system is too old and the new software may not be compatible. Upgrading the system is very simple. Go to the phone settings, find "About Phone" or "System Update" and see if there is a new version waiting for you to download.
Is there a problem with the installation package?
The downloaded installation package may be damaged or not suitable for your phone at all. Then download from official or reliable channels, remember to choose the appropriate mobile phone model and system version!
Give a chestnut
If your Xiaomi mobile phone is MIUI 12 system, but the software you want to install needs MIUI 13, it will definitely not be installed. Similarly, damaged or mismatched installation packages will also fail.
solution
Check the phone and system version first. If there is no problem, it may be the installation package. Try reloading or changing the source file. Be sure to understand the system requirements and compatibility of the software before installation to avoid making mistakes again!
