Taking screenshots by the traditional Volume Down Button + Power Button way is more common and requires a little effort with both hands as well. This sneaky trick will let you take screenshots with a three-finger slide on the screen, no need to push any buttons or anything, just swipe the 3 fingers down and you are done.
1. Make sure the three-finger screenshot is turned on
Setting method:
realme UI 1.0 & 2.0: Settings > Additional Settings > Screenshot > 3-finger swipe down
realme UI 3.0: Settings > System Settings > Screenshot > 3-finger swipe down
ColorOS 6.0: Settings > Convenience Tools > Gesture & Motion > 3-Finger swipe down
realme R & Go Edition: not support
2. You can restart your phone and try again
3. Go to realme UI 3.0: Settings > About device > Up to date
realme UI 2.0 & 1.0: Settings > Software update
ColorOS 6.0: Settings > Software update
4. Back up data and reset factory settings to try again.
Path:
ColorOS 6.0: Settings > Additional Settings > Backup and Reset > Reset to factory settings > Erase all data, enter the password and click "Clear Data".
realme UI 2.0 & 1.0: Settings > Additional Settings > Reset Phone > Erase all data, enter password and click "Clear Data".
realme UI 3.0: Settings > System Settings > Back up and reset >Reset Phone >Erase all data, enter password and click "Clear Data".
If the above methods still cannot solve your problem, please back up your data in advance, and take the purchase certificate to a nearby realme Customer Service Center for testing.
