Now the UI interaction of mainstream brands is getting better and better, and some important functions are dominated by Android machines, such as application double opening, infrared remote control, etc. Most Android machines can easily reach at least two or three years of service life on the basis of ensuring smooth operation, but because the Android machine has more pre-installed software and cannot be uninstalled, it is recommended to choose a large cup of memory, at least 8 + 128G to start. In addition, you also don't forget to make reasonable use of the old machine, to transfer your idle flow, back to the blood to buy a new machine is not painful!
