    Decent phone , love the oled 120 hz buttery smooth screen and the insanely nice fast and responsive camera and interface BUT ..... it’s a Samsung Prodcut , Samsung ecosystem is orettt terrible , the phone is amazing and very handy with all the tools , definitely for a independent contractor , don’t buy used best buy won’t help you if it has even minor problems

    Personally did not prefer the S21 coming from a Note 9. Returned it and got an IPhone.
