Fixed!!! Flickering keyboard issue!
This has affected numbers on my iPhone 13 max. I do not use any 3rd party messaging apps nor do I use any other 3rd party browsers.
I fixed my blinking issue
step 1
close all open apps
step 2
go to “settings” > “general” > “keyboard”
turn off “predictive”
restart iPhone
If this does not correct issue:
step 2
Go to “settings” > “transfer or reset iPhone”
select “reset”
select “reset keyboard dictionary”
hope this helps!
