Welcome to Android Central! Try wiping the cache partition:

Diddy, your instructions were not correct you have to go to storage hit that then go to internal storage hit that then you watch it calculate and then you hit cached data and wipe out the cache. I did it and I had 2.14 gigabytes in there so that was substantial and then I tried to restore Facebook and play a video that kept failing. I if failed badly again and then Facebook crashed and wouldn't start after I closed it. So I uninstalled it and reinstalled it. Facebook takes about 17 seconds or more to load into the tablet & it takes about a half a second on my Galaxy Note 2 and the Galaxy Note 4. Something is wrong with this tablet
So, with the new cache settings, after I uninstalled and reinstalled , and the install process took quite a long time comma I tried to open up Facebook which it did and I tried to play that same video and it crashed again immediately. So it doesn't appear that the cache is the problem. Like I have been saying it's the design of this tablet with only one gigabyte of memory it cannot handle the programs that are out today such as Facebook. I'm trying to run these very big programs with 20-30 and 40 megabytes of RAM and that's not possible.
I want LG to take this piece of garbage back and replace it with a new model that has 2 gigabytes of RAM I believe it's their B model. This is completely inefficient and insufficient and should not have been released. It is garbage and it's time LG steps up.
As you might have noted I sent this tablet back to LG months ago explaining all the problems that I was having and they fixed an antenna that had nothing to do with the memory problem. An interesting thing I noticed this morning was there is a picture on Facebook that's 3D and I could see it in 360° on my Galaxy Note 2 and Galaxy Note 4 but no 360° on the LG G Pad 8. There isn't even a 360° icon.
Plus, the earphone jack doesn't seem to work properly and the SD card keeps unmounting and unmounting and remounting and unmounting. I was really thinking about getting the v20 but when I saw I could get a nice note for, I decided to stay the hell away from LG because they produce garbage.
Let's see if LG reads this and swaps on this piece of crap for the newer model. I know sending it back for factory repair will be a waste of time and then I'll need a day to reconfigure. If LG doesn't fix this situation I'll go to Twitter and tell everyone about it. At least Samsung is standing up with their Note 7.
