    • A very good phone and a great value
Purchased for my wife and she is very pleased with it. Everything is as just as we hoped it would be. I never hear her complaining about anything so I would recommend this item. Battery life is very good and the value for the money is spot on.

    • Worth my money
So far good, I got tired of being t-mobile slave with payments. Bought this phone here and so far I love it. My main use is for calls and taking pictures here and there. So far battery life is good, it has lasted me for up to 2 days without charging with slight use. I have not tried to go beyond that. Pictures have good quality. Sound is good, no problems connecting through Bluetooth or wifi. I use it with t-mobile . ... show more

    • Flagship phone at great price
Great phone. Feels a bit lighter than it's predecessor. The price was good too. Taking the sim card out if the old phone and putting it in the new one went smoothly. Now, the delivery was a completely different story. The Amazon delivery person left my package sitting outside my apartment building. It really was a miracle it wasn't stolen! Press any apartment button to gain access to the staircase, is it that hard? ... show more

    • Doesn't come with all parts to recharge.
There wasn't a way to charge phone. I had to order cords afterwards. I can't get messenger to open articles that I send to others. It came only 18% charged so I don't know if my battery is as good as it should be. It was hard to find instructions on how to use, turn it on, turn it off,... I don't like that to take a screenshot, you push 2 buttons on the same side. Otherwise it seems to work well and I'm enjoying it. ... show more

    • Great phone for the money.
This phone holds it's charge usually the entire day and I am on it all day. I like the idea of facial recognition but quite a few times it doesn't recognize me. Not having luck with the finger print but it could be from the glass protection. The price is way cheaper than if I bought it at the telephone store. ... show more

    • Would not charge or turn on/Replacment won't accept SIM/Screen stopped working
Update 2: I love this phone!! Huge upgrade from my Galaxy A6. The setup process was a nightmare but it finally works. You most likely have to go to your carrier and pay an activation fee to use it like I did because simply putting my Sim card in did not work. I am giving 5 stars for the phone but I would give 0 stars for how this whole process went Update: Amazon sent a replacement phone the next day and it works! The graphics are great! Games run a lot smoother and it charges super fast. Keep in mind that this is my first S series phone so I am amazed to be able to run more than 2 apps without my phone crashing. New problem: My SIM card doesn't work. I am taking it to MetroPCS to see if I can get help. This whole process has been difficult. I was really hoping to just pop the SIM in and start using right away. Disappointing. I was super excited to get this phone because I have never had an S series Galaxy phone before. When I opened the box it would not turn on. It didn't come with a charger and I did not own one so I had to wait for one to arrive in the mail because no store had them in stock near me. Finally plugged it in and nothing happens. Even the phone store I took it to couldn't figure it out. Amazon is sending me a replacement and I'll update my review once I actually get to use the phone. I am very shocked and disappointed in Samsung. I seem to be the only one with the problem of recieving a dead phone. Hopefully the replacement will work. Update 3: This model sucks. The screen stopped working less than 2 years after buying it. Not sure if I'm going to buy a Samsung again. All that money for nothing special ... show more

    • Easy Setup
The phone comes with everything you need to flawlessly set up your phone. Had an AT&T SIM and set up my settings and apps from my s9+ with ease. Does not come with a charging cable, but it takes C-USB like most samsungs.
