Z10 keyboard input not working.

My sister an avid z10 user just had an issue with her phone.
Does anyone know how to fix keyboard input issue. Letters and numbers on keyboard not responding, sound is produced when keys pressed but the letters don't appear in text. Emoticons work perfectly. Battery pull and reset has been attempted but no use. Is there an easy fix without reinstalling the OS. She's running the latest 10.2 os.
Ps. Could use of instagram b the cause. As she recently installed the app.
Any help would b appreciated.
Thanx.

Possible the Instagram app did it. Go Native app and install Igrann for Instagram.
Try the new OS http://forums.crackberry.com/bb10-le...evices-953873/
Also a hard reset may fix the problem, Try Vol up and Down key at same time 10 seconds does a hard reset.

Thanks for suggestions, tried everything, nothing worked. Security wipe was the last option. Since security wipe all works perfectly.
Thanks anyways.
