Hi, hope someone can offer some sane advice regarding my cherished Nexus 7. It's the wifi model, and since I installed Lollipop it has been the biggest waste of time known to man. It wasn't so good with Kitkat but Lollipop has reduced it to a glacial like speed of processing, apps such as Chrome, facebook etc keep freezing and locking to the point where I'm ready for binning it and getting a Windows tablet! I did try some things suggested on the Daily Telegraph site such as clearing cache and altering Window animation scale etc and it seemed to work, but just a few days later and it's dragging it's heels again. is there ANYTHING I can do to get this thing flying again? It used to be a joy to use, it could outpace my swiping and selecting etc but now it moves like treacle! many thanks, Lol.
