Works very well. Some disappointment with the software changes. Have not figured out how to set separate tones for different app notifications. Also not able to insert SD card. They want you to use the "cloud".
I got the s21 after owning a s8. I like the finger reader on the 8 better. But im getting use to the 21. The google assist pops up to much even after you turn it off. The square at the bottom is to sensitive. Better after you get a case. I miss the jack for earphones. Be ready to spend more money for the extras.
I give it 4 star just because the battery doesn't last at least 8hrs with normal use! If you use it more than usual by 9am you just have 40% left o battery life. Other than that storage, screen sensitivity, picture quality and the speaker is remarkable.
