Good phone for what you pay. Screen looks good, starts up fast, no issues with app or software so far. Went from a S7 active (whish they still made the active series) to this guy, I don't need anything fancy just durable enough for me, can run bank and basic apps and can do voice and text.
Only real disappointment was to find that the phone dose not include wireless charging capability, Samsung should included this capability as its a 50cent part that takes up almost no additional internal room of the phone.
I give this 4 stars for now. Just been a week. Set up was easy and the phone is working well. I am enjoying the fast speeds, great sound, and expanded space. Still getting used to the changes in swipes and the power button. But I will get there. So far, so good. I am pleased with my upgrade to the A51 --smart economical choice!
In general this is a solid smartphone. I like the form factor and the weight. The battery life has really impressed me. The only idiosyncrasies I have noticed are that the display seems to show a cartoonish aspect to some indoor photos and that the speaker is inferior for the quality I would expect from this phone. Aside from this, I am very pleased with this phone.
