MY PHONE IS INSANELY LAGGY

Ever since I installed the new update and/or experience a glitchy app (Followes app for Instagram, which is now deleted) I have been experiencing these things on my iPhone 7+:

1. Camera is gone on locked screen. I did go to settings to enable it and it was never restricted. Camera icon is on home screen but does not exist on locked screen.

2. My phone is insanely slow now. When I text, my typing is so slow it sends the text incomplete, because it cannot keep up with my fingers typing out words.

3. Text messes sometimes do not send.

4. I notice that when My my phone is connected to a WiFi, it is slower. Instagram takes forevwr to load, Facebook, a web page... and when I type a comment on Facebook, it takes forever to submit the comment and sometimes comments the same thing twice. This also happened with Venmo. It took so long to submit a payment that the first transaction didn’t work, so I submitted a second one, and the first one finally went through, thus paying twice.

Keep in mind, I do turn my phone off to restart it. At this point, I might have to recover the old update and wipe this one. But is that my only choice?
