Re: Screen protector
I never used screen protectors when Apple had curved display glass. Since the 12 series with flat glass, absolutely. Always got the full glass cover (ones with notch were awful). My 13 Pro Max screen has never been touched by a finger, as soon as it was taken out of the box the first thing I did was put on a tempered glass! Will do that from this point out as long as the glass is flat. None of my Samsung phones have had them due to curved glass as well.
Point is if you use a tempered glass protector, you will never have micro scratches and the screen glass will always look new which is good for resale. Also in the event of a drop, the risk of screen glass damage is reduced tremendously.
No need to over pay as well. Glass is glass and paying $40 for one is a waste of money. The cheap ones on Amazon that include the plastic alignment frame costing under $20 for 2 or 3 protectors work and look great IMHO.
