[Q] Galaxy S4 slowed down
I've noticed lately that my S4, which I've had since June, shortly after Verizon got it, getting slower and lagging when I press the home button and when I open the app drawer. I've also noticed it slow when I'm using Google Play Music and switch songs on the lock screen, there is a visible delay but the song switches promptly. Another thing worth pointing out is that when the screen is off and I wave my hand over it for the briefing, it shows it for a bit then switches to the lock screen.
As a side note, I do have about 3.5 GB of Google Play All-Access music cached for offline listening on flights and such. In addition, I've notice that my mom's S3 has no lag despite having it longer and way more apps on hers. How can this be?
How can I fix the slowness without wiping the entire phone?
