My SCH-I500 is lagging and really slow. I rooted my phone using oldin and the only reason I did it was for wireless tether... Ever since I started go sms and go launcher ex it slowed down and always restarted into safe mode. I dont want to lose all of my apps or app data or all my data. I have no clue what roms r and didnt wanna mess with them because I didnt want to mess up my phone... Any ideas?
