I bought a7000 before 2 months and its keyboard sucks.. is there any option to change my a7000 ? how can i change?
Of course you guys can. Simply download a new keyboard from Google Play store, there's a lot of them free to download there. After installing a new keyboard, (this may differ in your phone, but should look/sound similar) go to Settings > Language & input > enable the keyboard you just downloaded > Change the default keyboard to use.
