Given, how terrible the QC has been in this pandemic era. I would rather sit tight and won't update not alone for 120 hz and under display scanner.Are you suggesting it would be wise to skip the 12S/13 this year? Possibly not a bad idea, especially if there are intentions to go to 120Hz displays and under display finger print sensors. Gives Apple an additional year to iron out glitches.
They have ****ed up the calibration of normal 60 hz display this year, God knows what will happen with 120 hz and UD scanner.
I guess, best way to guard yourself is not to be the 1st one to buy and wait for couple of months, and watch out how fairly they have done with the new phones and to make sure that their is no "GATE" or something.
