As thread title? Is the tablet’s memeory upgradable?
If you mean storage, no, there’s no expandable capacity. However, with this “On The Go” cable
and this USB microdrive
I doubled the storage capacity on mine to 64Gb for £20.
If you mean RAM, no, unless you’re prepared to break the device open and know what you’re about. Even then, still probably no.
BTW, to use the usb drive I have the Nexus Media Importer app
