It just took me 40 seconds to switch from Facebook to my SMS. (I got a message while I was in Facebook App, and I clicked on the SMS pop-up and it took good 40 seconds to make the switch)
While thankfully not everything takes this long, I am curious to try to diagnoze what could be the issue. I have no idea where to begin. Most other things take anywhere from good 2-5 seconds, like app switches, email send-offs, etc.
Can I have some troubleshooting steps I can use to make some steps towards speeding up my phone?
Factory Reset does help, but I have done 3 of those in the last 1.5-2 years and I would rather do something else now. Maybe figure out what the issue is rather than just postponing it again via Factory Reset.
