Please download a different keyboard application from either Samsung Apps or Google play store. You can for example download a keypad with Large letters if your handset default keypad letters are to small. Enjoy :)

I have bought samsung gt-c6712 now while connecting wi fi it is showing dns failed please give me solution


Delete your wifi connection from your phone and re-create it.
Entering the wifi key again should clear this problem.

If you dont know your wifi key, you need to login to your router and get it from there.
