The lifecycle of electronic products is getting faster and faster, and there will be new products in almost a few months. The three tablet systems also cause headaches for OEMs. IOS is not open and cannot be done. Windows 8 is copyrighted, high cost; Secondary Development of Android is difficult to innovate; the Ubuntu tablet syst

storage space is very large, such as 16g or 32g, where 16g and 32g refers to the total size of the disk, the equivalent of your newly-bought computer a new hard disk. When the phone comes out of the factory, it will burn Android on this disk, the Android system will partition the entire disk, part of the Android system can be used to store system files, similar to the Windows system disk, but more than the

My suggestion is that when the memory is not 8G, the memory is twice
