I installed IOS 14.6 this morning. it looks all apps/functions no longer slow or laggy.


However internet speed is slower than before (IOS 14.6: Over 200 Mbps) after the restated


internet speeds are ranged from 100 Mbps to 130 Mbps.


after having waited for 10 mins to 20 mins, it comes to the previous speed.


at this point, my phone doesn't have any issue after installing IOS 14.6
