Well, it's all the more reason for me to hang on to my S20 Ultra. I use BT buds, but it's the principle.
As for the external sd card, I very definitely use it, mostly for backups with smart switch & up to the S20 Ultra, it's always been much easier to restore your old phone to your new phone with the sd card backup.
The Notification LED removal served no purpose but to annoy people, & again, Samsung *said* that they were working on something, they never did.
Yes there's some alternatives on the Play Store, aodNOTIFY for example but it's not as good.
I'm just really disappointed in the direction Samsung is going.
Worst of all, what's the reason for making these regressive changes??
If I had the S9+ (awesome phone!), I'd probably get the S20 Ultra, right now it's the last good, ie: fairly complete Samsung phone, except for the HR sensor, for that you'd have to go to the S10+.
I've said it many times now, but there's no way in he-double hockey sticks, that I'd get the S21 Ultra!
I haven't checked the prices, but from my experience Samsung phones don't hold their value anywhere near as much as they used to.
