I just got my phone, and I am downloading some new apps, and I noticed that the speed is very slow. There are times where the wifi won't even connect, and i get this retry prompt in the app store. I used my older iphone 7, and there was no issues. Youtube app is also very slow. I am not sure if there is something wrong with the phone or the phone is still configuring itself(sorry, don't know the exact terms for this) itself.
