| 1. If you erase the persist on a device with a fingerprint sensor, the device will not be able to use wifi and sensors, some time phone lost internal memory.
2. Disabling finddevice(delete or do some thing with finddevice.apk) on devices running miui 10 or later may cause continuous crashes, with devices running miui 11 after connecting the wifi the phone will automatically download finddevice.apk and install it after reboot. you can only install custom fw on your phone to hide mi services but that requires unlocking the device bootloader. |
