[Q] New Android User Having A Lot Of Problems
Well hello first I'm new here I was an iPhone user so I'm having problems with the whole OS that is Android I don't understand anything here, I bought a Galaxy S4 (M919) from T-Mobile cause I wanted to try something different and I tought the Galaxy S4 was the right choice for me, I don't want to regret switching to Android mainly because almost all the apps I used on my iPhone are not on Android I have looked so much for like tweaks or stuff like that that I used to do on my iPhone with cydia but I can't find anything, almost all the themes I find are so ugly well I come here to find help and make understand all the capabilitites of Android.
So I bought my phone from T-Mobile paid full price for it to get it unlocked unfortunately they haven't helped at all with unlocking it, I found a guide here that was dialing a number to go on service mode and change some settings I have tried this method so many times and it hasn't worked I even accidentally deleted the backup on the last step, I'm so lost I would appreciate some help on this matter.
I have been looking for ROMs mainly to help on battery life and movings app to my sd card any recommendations on which ROM should I pick and some guide on how to install it.
Any help intoducing me on the Android OS would be gladly appreciated and thanks for reading this.
