Good day, ladies and gentlemen!
Actually, I list the bugs found:
The fingerprint scanner stops working after a reboot and you cannot add a new fingerprint.
The cellular receiver catches the network signal two levels lower (if not more), compared with the stock firmware MIUI 9 - v188.8.131.52
GPS very slowly determines the location.
I express my deepest gratitude to the developer @GuaiYiHu for the great work on the 10th version of the android for our Redmi 3. Indeed, thanks to the hard work of the respected GuaiYiHu, we(owners of Redmi 3) can not worry about buying a new smartphone.
I hope that the esteemed person under the nickname GuaiYiHu will be able to overcome the above bugs.
Thanks again for the work.
