I will tell you how to increase the RAM by Android For people who are not strong in definitions, I will tell you what RAM is. This is a fast flash memory that is responsible for running programs, that is, during its operation, software is stored not only in the device's memory, but also in RAM, so that the operation of both the application and the entire system as a whole is responsive. If RAM is not enough, then it starts to freeze completely Android or at least work slower.
The main ways to increase memory
If in an ordinary PC such a procedure is carried out by adding or replacing strips with this memory, then in devices like a tablet, this possibility does not exist. Because this board is soldered to the main board to achieve the smallest possible device size.
When asked whether it is possible to increase the RAM on Android? The answer is depending on what purpose is being pursued.
If you need to increase free memory, then you need to remove some unused applications, they can unload your device.
If you add a physical volume, then this is unlikely, because initially such a function was not provided, if when buying a device it is written that it has 512 Megabytes, then they cannot be added in the future as on a PC. But there is one way.

SWАPitRАMEXPАNDER program
You can increase free RAM by Android by downloading the SWAPitRAMEXPANDER program. This product creates a paging file that can be 2.5 GB in size. This program creates swap files that manage applications that do not use a lot of resources, this frees up regular RAM for more resource-intensive applications. That is, you can run many small applications, and the RAM size will hardly change, which takes the load off the system and makes it faster.
Also, you can still make the amount of RAM on Android at the expense of an SD card, just by selecting External_SD in the settings. 
Note: For SWAPitRAMEXPANDER to work properly, your device must have a ROOT right.
