Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
When it comes to the keyboard, try to clear data for Xperia keyboard under settings > apps> all > Xperia keyboard > clear data.
If you still experience any error/fault in the camera after a software repair, I suggest that you have your phone examined by a service center. Please contact your local Xperia support team for more information:

Sell it on half price and buy something from notable brand. Front and back cameras won't be fixed with software, because of Sony's expertise on hardware design - they are crap in one word. Enter key is working on 4.1.2 based stock roms - either try to downgrade phone software or install any keyboard which you like from Play Store.
Nah i wont, the enter key is okay now after i update but the camera was the big issue.
