The letters and numbers on the keyboard on my BLU STUDIO 6 keep disappearing every time I start typing , can someone please help me with this problem?
Go to settings»applications»all, find the keyboard you are using and clear the data and try again. If the problem isn’t resolved, install a third-party keyboard and see if you have more luck that way.
My phone came without a keyboard installed, I would like help in installing one. Remember no keyboard means I can’t type on my phone.
just reset mobile the all old setting will be working fine.
