Well I do thank you for posting this.. I tried but could not find Touch input,, I did find Android keyboard,, ad cleared the cache.. no good.. I then went to Settings.. took a deep breath and cleared that cache also.. still no good,, I rebooted the fone,, still wont open the keyboard..so.. last resort i took out the battery as there is no Reset button or hole on this fone,, so removed the battery,, and using the metal tip of charger connector,, shorted out the battery connectors on the fone.. This cannot damage the phone, but will remove any small charge still lingering inside..
I replaced the battery..restarted the phone and BINGO.. keyboard is back.
So.. dont know how long it will last but fingers crossed.. phone is MITO A 100 Android 2,3,6 2013 model
