The highlight of this smartphone is the 8K video recording which is one of the best resolution out there if you are into vlogging and you can edit videos straight from the phone without a need of a computer. Although all this performance comes with a cost which is overheating, not a big issue if you use it for casual gaming or simple multitasking. There are different variant to choose from like in the internal memory or RAM but expect it will get quite expensive if you opted to choose the top end specs.
