Hi, Thanks for this how to ! It worked like a charm !

I've seen the issue reported already but no actual solution : I have a issue with notifications.
Sometimes, the notification with messaging apps (whatsapp, signal, maybe others) are displayed only when I open the app, which is anoying.

So far I have :
  • Disabled battery optimisation for those apps
  • Checked that notifications are enabled for the apps

I'm sorry if it's off topic, but since I did not notice the issue with the latest standard ROM nor with the Lineage ROM, it may be related.

It appears to be an issues acrossed android 11 OEM firmware phones (Chinese?). Happens to my Blackshark 3 too running Android 11. For some reasons, its a new way of the firmware how to improved battery life (or bugged). I've observed that keeping the app running in the background solves some of my notifications issue. Or if you can get an app drawer that has an option to PIN the app in recents tab preventing to kill the app process. Just try it for yourself goodluck

Install the Gboard apk and Qinpad apk from the zip download > open Gboard app and set it up.
Everytime you will type, an input notification switcher will appear on your notification bar and choose Qinpad as input. That will fix your keypad

Thank you. Is there any version with auto spell/type whole word? As opposed to qinpad which can only type a letter at a time? Thanx

Wao thanks a lot : i did that too and it works like a charm now (Proton mail, gmail, signal and whatsapp).

For systemizer to list my apps, the version available in magisk was not working (17.3.1), I had to switch to 17.4.1 - seems to be an issue with android 11.

Haven't tried that coz mine came with bootloader unlocked already. Try to flash it now. Someone said he got a bootloop after using the tool but it still unlocked the bootloader.

the firmware is a custom OEM firmware. the official update still intact. its normal to fail because unlocking the bootloader of any phone will brake its system updates. I just ignore it

    TalkBack not working in this phone. BUT..... there might be a work around using Google's voice assistant. It could read messages, direct call a contact, open apps, compse sms, compose and read calendar entries, etc... Everything could be hands free with a pair of earbuds!

    Install these apps from Playstore

    Key Mapper - a more better app to assign anything to buttons to open apps, command tasks, and navigate normal functions on your phone. The quick short cut assignment in settings is good but too little features and it will only works when you're in Homescreen. This app makes button shortcuts works even if you're INSIDE ANY APP

    Key Mapper - Apps on Google Play

    Unleash your keys! Open source!
    play.google.com play.google.com

    Google App + Assistant App - Hey Google/OK Google may not work but assigning the Assistant App to our button will be the work around

    TUTORIAL UPDATE!

    MY DEVICE IS 4/64 with unlocked bootloader

    Unofficial Qin F21 Pro (MTK chipset) firmware, version 1.1.1 multilanguage.
    Thanks to @redsat, @gaguga and the whole 4pda community.
    Install at your own risk and responsibility.
    For testing purposes only, will be updated or changed if necessary.
    Use SP flash tool for flashing, bootloader should be unlocked on the phone (via @mlgmxyysd tool or Ubuntu boot image). Having the full own ROM dump is highly recommended in advance.

    Changes:
    -Removed chinese applications
    -Decrypted data partition
    -APK installer with no restrictions
    -System partitions are writable
    TWRP recovery 3.6.0_11-0 is added
    (In TWRP the phone memory is accessible via path: /data/media/0)


    WARNING: FLASHING THE FIRMWARE WILL WIPE EVERYTHING! I SUGGEST BACKUP IMPORTANT FILES BEFORE DOING THIS. I WILL NOT BE HELD RESPONSIBLE IF YOUR PHONE DONT BOOT, SOFT/HARD BRICKED! THIS TUTORIAL IS TO DO AT YOUR OWN RISK!

    ALL FILES REQUIRED FOR WINDOWS     https://www.mediafire.com/file/tl8hv77gl0vo6sd/qin_f21_pro_mtk.zip/file

    1. download and extract zip
    2. extract "F21PRO_1.1.1 (2).zip" (the firmware)
    3. extract "SP_Flash_Tool_V5.zip" (flash tool)
    4. install drivers
    5. open "flash_tool.exe"
    6. select scatter file from the firmware folder
    7. click download
    8. turn phone off
    9. hold back button then plug usb cable to pc. It should start flashing
    10. after download complete, unplug then boot to TWRP then reset factory
    11. Congrats! You now have chinese free apps firmware with TWRP Installed
    12. If it wont boot "DEVICE ENCRYPTED", just go to TWRP and FORMAT DATA then reboot (it should boot to system now)
    13. transfer "boot_2.img" phone or transfer it to a USB Flashdrive (more easier to locate) (FOR 3/32 VARIANTS TRY TO USE THIS BOOT IMAGE BOOT.IMG 3/32)
    14. boot to TWRP once again
    15. go to device path /data/media/0 or USB storage path using OTG
    16. FLASH IMAGE "boot_2.img" to boot partition to fix the device twrp path to /sdcard (IMPORTANT! boot is an IMAGE FILE not ZIP FILE. by default, TWRP is set to check for zip file and will n0t se IMAGE FILES in the directories. YOU NEED TO TAP THE INSTAL IMAGE BUTTON so image files will appear)
    17. reboot and proceed to installing ROOT and Google services
    HOW TO BOOT TWRP:

    * + heart button (upper left) + power on. once douqin logo appears press up button + power on immediately. TWRP first boot is in Russian language. just change it to english change twrp language


    HOW TO ROOT + GAPPS with playstore certified + fix keypad annoying issue

    1. transfer all the app APK from the "APK" folder youve download
    2. install everything (QinPad be a more stable keypad input)
    3. open gboard and enabled both gboard and QinPad (this should give you a quick switch of input in the notification bar everytime you will type something)
    4. open MAgisk app and update the apps to 22.1. phone reboots (DO NOT UPDATE TO VERSION 24.3)
    5. Open magisk again then Install Magisk > Select a patch file > choose "boot_2.img" in your directory (path where you transfer it)
    6. transfer "open_gapps-arm64-11.0-pico-20211217.zip" to device
    7. boot to TWRP
    8. FLASH IMAGE "boot_2.img_patch" IN THE BOOT PARTITION. then reboot. should be found in download path in TWRP
    9. go TWRP again and flash "open_gapps-arm64-11.0-pico-20211217.zip"
    10. reboot > SYSTEM
    11. you will see playstore. you will have an annoying message "device isnt playstore certified" just ignore it
    12. open MAGISK app go to settings and enable MAGISK HIDE, search module and install "Busybox for NDK" then reboot
    13. open MAGISK app, search module and install "MagiskHide Props Config" then reboot
    14. open Terminal emulator app
    15. type "su" enter (grant permission)
    16. type "props" enter
    17. type "1" enter
    18. type "F" enter
    19. type "30" enter
    20. type "25" enter
    21. type "2" enter
    22. type "y" enter
    23. type "y" enter (phone reboots)
    24. after reboot wait gapps to update (around 5-10 mins) then sign in to playstore
    25. you've now enter Playstore
    26. go to playstore settings > about > click update playstore
    27. wait for it to update the version and keep checking in playstore settings > about > IF DEVICE IS CERTIFIED
    28. If the updated playstore still said " DEVICE IS NOT CERTIFIED", proceed to manual
    29. install device id apps from playstore and copy your GSF ID
    30. register it manually here > https://www.google.com/android/uncertified/?pli=1
    31. go settings ~ apps and look for playstore and play services and clear data. reboot phone and Playstore should be certified!
    Congats! your phone now is rooted with twrp, no more chinese apps, and with fully working google services. I suggest perform a TWRP backup and store it somewhere safe for future use.


    HOW TO FIX NO/DELAYED INSTALLED APPS NOTIFICATIONS

    Thanks for JawadEly for the info, it works!

    1. Install all your apps
    2. Install terminal emulator app and system app remover app from playstore (this will give you the apk path you want to systemize)

    3. open magisk, search and intall "APP SYSTEMIZER" module then reboot.
    4. open terminal emulator app
    6. type "su" and grant the permission
    7. type "systemize"
    8. You need to set Selinux = TRUE by choosing "s"
    9. once its set to TRUE, you can now systemize any app provided you know the apk path of the apps installed.
    10. enter "3", here is where you put the apk path of the app you want to systemize
    11. to get the apk path of installed app open the "system app remover" app you installed.
    12. go to user apps and LONG PRESS an app you wish to systemize.
    13. copy the apk path then go to terminal emulator and paste it. Type "1" to confirm.
    14. Go to settings > apps list > clear storage of that app you transfer as system app
    15. done! just repeat the proceedure for each app you wish to fix the notifications.

    BEWARE! Be careful using system app remover. Don't uninstall system apps required for the android system. You might end up in a bootloop. This app is also used to remove bloatwares of OEM firmwares.

    I made this tutorial as DETAILED and as EASY TO FOLLOW as posible. Credits to 4pda community group and for individuals who contributed that made all this posible. Sorry if my English bad. Not my native language. If you lke the tutorial, you can buy me a beer.

    I bought a cracked version of the 4/64 version of Xiaomi Qin F21 Pro unlocked bootloader, rooted, and with preinstalled fully working Google Playstore and Play services running on the official firmware 2.0.8.

    But lately there's a very nice update development from 4PDA website for the device! It took me a while before I made it work and a lot of trial and error.

    I will make a full detailed easy to follow step by step tutorials on how to do it with all the links for the files required.

    The results will be:

    • A fully converted v1.1.1 custom firmware without the chinese apps
    • TWRP Recovery
    • fully rooted
    • certified playstore and google services fully working
    • THE PROCESS COULD ALSO UNBRICKED THE PHONE

    Requirements:

    • PC
    • UNLOCKED BOOTLOADER Xiaomi Qin F21 Pro (MTK soc) V1.0+ V2.0+ (4/64gb ONLY)
    • Files (will be provided)
    • working brain

    CREDITS:

    • 4PDA FORUMS device thread
    • Telegram Group
    • DEVS for the unlock bootloader tool
    • DEVS for the Custom Firmware
    • DEVS for porting TWRP
    • testers
    • many more I probably forgot
