Give you some facts before install that Miui 14 GSI:
- It has many bugs, you can read about it somewhere
- Bugs appear even flash fastboot rom (stock Miui) through PC. You will get some weird bugs that maybe can't fix even with PC
- Some reported that they just can open TWRP but can't boot in stock Miui and storage is empty
- So if you dont even have PC, you should know that once you flash this one, you will stuck with it maybe forever.
