I bought a parallel Motorola XT702, originally the phone RAM was 256 and ROM was 512

Normal,Android system is like this,Background running programs take up a lot of space,And XT702's RAM is already small,256RAM is actually available without 256,This is all like this。 My defy's RAM is 512,The actual usable is about 470M,Hit about 40 software,Usually the RAM is more than 100 left.,It's okay to kill more processes.,Release the memory to clean up 200M.,Add useless programs to the automatic end.,So you can clean up a part.,256's is really too small.。

ROM is the installation space, which is equivalent to the C disk of the computer. You installed the system, and you installed other auxiliary software, and it is normal to have so much left. How much ROM is left does not affect the speed of the phone, so don't worry about this. As long as it's not full.

RAM is the running memory of the mobile phone, which is equivalent to the memory of the computer, and the principle of the computer, as soon as you turn on the computer, there must be a lot of processes occupying memory, so how much RAM is left, this will affect your running speed.

Your hardware hasn't shrunk, don't worry. You can uninstall some useless auxiliary programs to make space. The system is so much, there is no way. The XT702 model is older, don't upgrade to a higher version, you can't run.

Hello,ROM is 512M plus some system programs and software are not much left,There are 190M is about the same,Your hardware is not shrinking,An Android system is about 200M,Plus Moto's software is about the same,I hope mine is helpful to you。

In fact, the system will remove part of the RAM, 100M RAM is normal, and even the RAM of 512 is about 300 left. As for the built-in memory, you can see if there are any junk files.

The 198M phone storage space is part of the 512M ROM, which is at the user's disposal. The difference between 198M and 512M of storage space is occupied by the system, preset programs, clients, etc.

The mobile phone ROM is the storage space of the mobile phone, including the storage space occupied by the system, the storage space occupied by the preset programs and clients, and the memory space at the user's disposal. A ROM is the equivalent of a computer's hard drive.

Mobile phone RAM is the memory called when the mobile phone is running, which mainly affects the system and program running speed of the mobile phone and the number of multi-threads, that is, the number of programs that can run at the same time. RAM has nothing to do with your phone's storage space, it is equivalent to your computer's memory.

Eh, this machine needs space to run the Android system, Eh, let's say this, RAM is equivalent to the C disk of the computer, which is the memory of the mobile phone.

System resources need to occupy memory, please be patient and wait for the official release of the upgrade package Add an 8G SD card to solve the problem 711 is the version software for the time being, and it cannot be installed or stored.

The data refers to the one that is not turned on.,After starting, because the system will occupy a step.,So it's only 198M.
