If you move the caret to the middle of the text, when you type the keyboard copies a section of the text.
If you type aaaaabbbbcccc| move the caret inbetween the a and b aaaaa|bbbbcccc and type d, you get aaaaabbbbccccd|bbbbcccc instead of the expected aaaaad|bbbbcccc
The problem is noticed on an android with Google keyboard. No problem editing text on PC. I will be very grateful for the help
