Mostly while take call it's switch its network automatically and if continued call a lot its like stuck so go to settings, connectivity network and choose 4g lte and then again change to 5g then it run in 5g again
Mostly I suggest do use any screen protector..Because phone strong itself for some falls under 1meter and I am using from a year with out any screen protector..If u think u going drop then it will..But stay use too it..It will give best experience
