So a couple of months ago I finally got to install the new update for my Insignia Flex 8" Tablet to Kit Kat 4.4.2. But apparently for some reason it has been working extremely slow, and its performance has greatly dropped. I thought this might be happening to everyone after installing this update, but it turns out that my friend who also updated his to Kit Kat works perfectly fine and there are no problems with it. I believe there might be a problem in the OS, if so, does anyone know how I can reinstall it? Thank you
