I have a Galaxy S3 from sprint and lately it is getting really slow and freezes up about every 5-10 minutes and it's really starting to bother me because I'll be in the middle of doing something and I have to set my phone down for a good 10 minutes before it starts acting right again. I've tried restarting it and deleting a bunch of unused apps. I really don't wanna factory reset it. I've had it since June 2013. Is it age? Any help is appreciated. Thanks
Also make sure you don't have tons of stuff running in the background. Over time you download things that you forget about, but they're set to start when you turn the phone on, so it's still running all those things you've forgotten about.
