ColorOS users with device decrypted or rooted should have Red blinking on status bar which is quite annoying. So here is the solution, I have patched SystemUI.apk which shouldn't display red blink.
Bonus: Upon request by few users I have also removed Blue Blink too which was supposed to be triggered when Hotspot is enabled.
The below zip file works for A20, A21 & A22. Download, reboot to recovery & flash. Enjoy
