The amount of crazy things that happened whenever my S20 FE would turn itself on in my pocket (Note to Samsung: Accidental Pocket Protection does NOT work!) is well, crazy. I tried turning off tap to wake, raise to wake, Always-on-display at certain times when my phone is in my pocket (Bixby Routines), and even then I'd feel a hot sensation in my left front pocket and I'd discover the phone was on for hours, battery at single digits, and having sent two texts with the message 'deajojofaeujofaoje' to a few contacts which made for awkward moments, opened a few dozen apps, and activated Samsung Pay.
It got so frustrating I ended up going to 2010 phones for a bit then when they couldn't make phone calls anymore, went to a cheaper A series with none of that. The battery is even better on the $150 Samsung than on the $700 Samsung. You explain that one to me! I thought paying more gave you more. I feel miffed the touch sound is so silent and subtle, as whenever my S4 would turn on in my pocket I'd know by it loudly going 'BWOP BWOP!' over and over again.
