My iPhone 6 Plus was glitching out and a restore wouldn't help, so I took the easy way out and bought an iPhone 8 (not a Plus this time, I was sick of stuffing it into my pocket for years). I didn't want to buy a case at the T-Mobile store because they are grossly overpriced. Instead I went to Amazon and found that the Amazon choice for a no-frills clear plastic case is on sale today for $5, including shipping.
