I have a functional Samsung Galaxy Tab 3 SM-T210R, but it is too slow. Is it possible to upgrade the motherboard to have more RAM? I saw this motherboard containing 8GB, but I am not sure if that is RAM or storage space. This is the link: Galaxy Tab 3 7.0 Motherboard
@karu28 no you cannot. the memory is actual a few IC’s that are soldered to the logic board and are not replaceable (well yes they are if you have a rework station, an IC programmer and the right chips etc.). the only thing you can do is a 64GB SD card for additional “memory” 8GB is your internal storage. They run at around 1.5GB of Ram for the OS etc.
