Ok so I installed a Japanese keyboard on my phone and I just wanted to know if I'm using it correctly. I think I know how to use it and how it works, but obviously I can't read kanji or actually speak Japanese (except for a few random words in romaji) so I have no idea what I'm really spelling xD

Sound on my iPhone 4S isn't working?

It stopped working today and I don't know why. When I have the headphones in it will play for a few minutes or seconds then stop. And when they're not in, it doesn't even give me the option to turn it up or down. I can't play anything out loud either.

How to recall deleted texts from an iPhone?

I was at a party the other night, and was texting my girlfriend. We got into a huge fight, but I was drinking and don't remember what it was all about.
I woke up the next day and I assume my girlfriend deleted out conversation because it wasn't on my phone anymore!
She was so mad at me, but refused to tell me what we were texting or what I said!
Is there a way, maybe on the net, that I can access deleted texts to see what she and I wrote to one another?

Improve iphone 5 battery life?

I've had my iphone for nearly a week now from brand new and the battery is just literally draining all the time. I've looked on the Internet and done most of the tips like turn off location services, Wi-Fi, iCloud, Siri, turned brightness down etc. But it still hasn't made a whole lot of difference. Does anyone else have another solution to the problem? I was thinking of just resetting the whole phone and seeing what happens. Or maybe I'm just being impatient and need to let the battery kick in more. Anyhow any advice would be real helpful, thanks
