Sense I updated my iPad to 8.2 I can no longer run apps that are memory intensive such as the NVR software I use to monitor surveillance cameras. Also Facebook is very slow to load and I can no longer multitask as running 2 or more apps will cause a crash. I think it may be a ram issue but don't know if it can be replaced. Any ideas? I should also mention I have also performed an additional update to I think 8.4.
