It fell from a tall place…and you're wondering why the screen won't come on? Are ya serious? My car hit a telephone pole and now the engine won't start. I added gas. Radio works. Key turns but engine won't run. Dude, you either killed or disconnected your screen. It's Miller

Before you try, download a ram meter app. See if you're actually fully utilizing the ram. Might be an internet connection that's slow. Or that you've got stuff running in the background slowing it.

Nope. It's a wish, a hope and a dream of every tablet owner that upgrading ram could be as easy as on a laptop or desktop. But these little buggers are a one time creation. Best you can do is add memory card (SD, micro SD) to expand STORAGE, not ram. Apples to oranges. Storage isn't speed. Maybe some company will see the potential and create an upgradable tablet. But cost to produce that, for the limited amount of ppl who would take advantage of it, is not worthwhile. Buy today for future proofing. Go ram heavy.
