using the latest crdroid and everything works perfectly. Therevis a bug in music app that music files cant be played unless you clear the cache of music app. My battery also says pluggin cant be charge at 100-95% even though i already pull out the cable.

    Flashing Instruction :

    • Always Have a full functional Backup. Just in case!
      [*]First time installing crDroid to your Redmi 4A, or coming from another ROM:

      ** Make sure you're running a proper working Recovery ( TWRP) Treble supported
      1) Copy crDroid zip, gapps zip to your device
      2) Boot into Recovery
      3) Wipe cache, system, dalvik cache , vendor & data (or just cache & system for a dirty flash).
      4) Flash ROM
      8) Flash gapps
      9) Boot up

      [*]Upgrading from earlier version of crDroid:
      The only difference between clean flash as above and upgrading is you just wipe system & cache, leaving data. Everything else is the same. ***Remember to always clean flash before reporting problems. Clean flashing is always the best method of ROM install.
      You need to flash GApps every-time you flash the ROM.
    Don't expect any support if you:
    • are not running the included kernel
    • have installed any mods such as Xposed!
    • have modified system files

    Is there any solution for device decryption unsuccessful error im also getting this error other Pie roms as well. :crying:

    Dose the phone ask you for pattern on boot ?
    If yes, go to TWRP -> Wipe -> Format data
    Then type yes

    Thank you for this awesome ROM: it works very fine! Reading mode tile, Gcam woks, good signal strenght, battery life, notification lights, only works very well form me. Little error: I have an internal error message, when turn on the device and UI is loaded, but it has no effect on the operation of the phone.
