    Phone work fine. Looks like the lcd screen was replaced. The problem was the sim card tray can't read sim. Kept saying there isn't any sim when there was. Tried another activated sim and still couldn't read sim.

    Prefer my S7

    I needed to get a new phone now rather than later because I had a hardware issue with the camera on my S7 which affected everything and anything that used the camera. I had planned to get a new one this year because the battery was losing its oomph & replacing rather than fixing was an easy decision. The the camera problem. I liked my S7 so I figured I would stick with Galaxy. I looked at all 3 S21's but decided on the S21 5G because I didn't need all the bells & whistles or the screen size. Now don't get me wrong, it is a nice phone but I will just say that many of the "upgrades" actually make the phone less desirable for me personally (like knobs vs touch screen on cars). The cost for me is intuitiveness. The slight width & weight increase make 1 handed use extremely difficult. Overtime ...

    Newer doesn't always mean better

    The phone does not have SD card capability, screen is smaller than my S9+ and really is no faster than the s9. Wish I had done more research on the model before I ordered it. Good phone for the price, just not the improvements over old models that I was expecting.

    Samsung on steroids!

    beautiful phone with nice feel to it. Amazing features and abilities but still a familiar Samsung. Using online tutorials is helpful as there are a lot of layers in this phone. The camera is a bit challenging as it has more options and features than i was used to in my old S7 but i'll just learn. clarity of photos and screen is amazing. this is a lot of phone for the price- a real high end model.

    Phone is stylish with easy to use features.

    This is my first venture with an android phone and I am very pleased. The size isn't too big. The battery lasts long. I'm still learning all the features. But navigating them has been easy. I would definitely recommend this phone to family and friends.

    small, lightweight, great features and at 70yrs. old very easy to use and understand.

    Exactly as I read and researched. I had a Galaxy JV3 for years. Not a man of change I wanted a new version. Simple to use and same format as my old phone. Excellent phone.
