Similar to the S8, but battery life is great
5 years ago
Coming from a Samsung S8, this phone is nearly identical functionally, with the exception of the upgraded cameras, and the 5G, but the noticeable difference is in battery life. My phone runs all day and still has plenty of gas at night, much better than the S8

Stop trying to be an iphone
5 years ago
They eliminated the ability to add an SD card. And it doesn't come with a charger. Stop copying Apple by making your customers suffer! Android users don't buy iPhones for a reason.
