The gestures are awesome! The best part of my old moto was turning on my flashlight just by shaking the phone. So convenient. Turning it on with any other phone is a whole process that takes forever.

About 6 montha ago I wanted to replace my S21 battery and checked with Samsung, who redirected me to iFixit. The only genuine Samsung S21 battery they had was only sold with the screen, which cost ~$130 or something. I didn’t need the screen…

Last month I checked again and saw they had a third party replacement battery for ~$30, same capacity. I bought it and popped it in. It’s been working fine.

Was it Samsung’s requirement that the battery only be sold with the screen? At the time, I would have rather had the genuine Samsung battery and would have paid a bit extra for it, but not $100 extra.

No one really knows how osmosis works.
