    I have had good service with all my Samsung Phones and this one is no exception. I was reluctant about the size, but I actually like it and find it more functional. I do wish, I could use a micro SD card and be able to remove the battery.

    I tried to get my husband to switch to an iPhone. After 3 months we upgraded the iPhone to get this new Samsung and he absolutely loves it! He is able to do everything he needs to do for work from this phone. Absolutely recommend to others, and he is right, it’s better than the iPhone.

    Awesome phone, handles all tasks with ease. Im not super into photography but the zoom capability of the camera is very impressive. Coming from a s20 fe the increase in screen size has been excellent for watching videos and the embedded fingerprint reader seems to be much more reliable this time around even with a screen protector on.
