M2 is currently a futures, which is generally unavailable, so don't consider it. The currently recommended model is Samsung note. This is Samsung's first cross-border phablet, which is of milestone significance. Dual-core cpu with built-in Samsung A9 architecture is absolutely top-notch. The 5.3-inch AMOLED panel is gorgeous, and the resolution of 1280*800 makes the effect clearer. You can't see any particles when you zoom in. 8 million cameras seem a little insufficient today, but the effect is absolutely first-class. Due to the listing of note2, the price of note has been greatly reduced, and now it can be obtained for less than 3,000. Don't worry, it is the king of the older generation, and it is definitely a second kill to deal with the current mobile phone software.
