1) Display. It's a joy to enjoy video content on. To me, thank God, the world is as black as black and the world as white as white. If the Minimum Width is increased to 449 in the Developer Options, the display will mimic the appearance of WQHD + at FHD + resolution. The 6.2-inch model, which I initially considered too huge because of my little hands, turned out to be just right. I use it at 30% brightness with no issues, and I put about 50% brightness out on the street.
2) Sound. The high quality sound from the provided headphones is a nice bonus. I've installed Poweramp and customized the equalizer to my liking, and everything is peachy except that my headphones keep falling out of my ears and need to be readjusted every ten to fifteen minutes.
Thirdly, a jack measuring 3.5 millimeters. The headphone jack on most smartphones is either on the top or doesn't exist at all. I have always used this connector, and I absolutely despise it being on top, therefore this is not acceptable to me, and I refuse to inconvenience myself by bringing an adaptor everywhere I go.
Four) The power pack is to my liking. My typical phone usage consists of making and receiving calls, sending and receiving texts, using social media, listening to music, and reading the news. After the fifth iPhone, which "turned off" at 80% at temperatures of 0-5 degrees, this one appears to be a portable Powerbank, with 40-50% of the charge still present by 23:00.
5). Camera. Again, after the 5th iPhone, this high-priced Camera that can record every individual hair in a beard looks excessive. The images are exceptionally sharp.
The "Safe Folder" folder, number 6, looks great. Instead of requiring additional software downloads, native support for storing private information is now available.
7) The speakerphone's little speaker is surprisingly loud; I can clearly hear everyone even though they're on the other end of the line.
8) My phone picks up the signal just fine; I don't even need Wi-Fi to access the web when in the train.
