hi everyone, I got trouble with these keys
As before, when I double pressed the Caps Lock key, it was always appeared the sentence "Caps Lock is locked" or double pressed the Fn key, it said "Fn is locked" or pressed Fn + Ctrl, it would appear the tablet with %, <, >, etc
now these keys dont work
as many time I press on Fn + Ctrl, it dont appear the tablet anymore

Does anyone here know the problem?
pls help me
