Tell Google what I think  well I'm not a great fan of Android due to incompatibility with this system .updates from any apps can cause problems  meaning an app might work on one device but not on another. You buy an app (but not anymore for me) then it gets an update and it does not work. I had a problem with the wifi icon greyed (wifi still worked even though grey means not connected) out rather than have a blue icon past several months. Googled the problem but not much luck with the solution. I deleted all the updates still no luck then deleted a piece of software called GOOGLE SETTINGS connected to GOOGLE PLAY SERVICES which was a previous update. By doing this it brought back the familier blue wifi icon to let you know you are connected. Unfortunately the latest update of Gmail crashes too on android so have rolled back to the factory version. I've been a great fan of Google for decades since they came on the scene  but Android versions does not cut it for me PLEASE FIX THESE ISSUES. Sorry to say if I can give no stars I would  so my score for this software 0/5.
