My phone is a little over a year old. I keep my casch clean & my files are not fulk if crap, I have optimized my phone, & I have anti-virus. My phone is running sooooo slow. It takes 15-30 sec to load my contacts, some apps pull up fairly quick but nothing is running like it should. Typing sometime there is a 5 sec lag time between my keying & it showing up. Is this something that happens to force you to buy a new phone, because you get so frustrated you just do or is this something I may be able to fix? I have an 8g sd card but the only thing thats on it photos cause apparently the galaxy rush doesn't want you to store anything to the sd card but photos & such. Please help. Do I need to do a factory reset or can I boost function another way?
