Have you tried a factory reset and re-installation of all your apps? That' probably what I would try under these circumstances.

Hello, thanks for the reply. Yes I tried a factory reset and it still does not work. The problem is the OS update and even a factory reset does not allow me to revert back to the previous OS version.... Does anyone know how to revert to a previous version of the OS? THANKS!

Can you provide me a list of apps you are having problems with? I will load them on my test systems and provide feedback to the Android team. When you say you did it a reset was that from within the OS or from the Droidboot menu? I normally recommend a wipe cash partition/ hard reset via the boot menu if you have issues after a OS update.

Thanks

Erin

Hello Erin,

Thank you for the response. Its nice to have someone actually try to help me instead of telling me its me or my app's fault.

I must reiterate that I had zero problems running my app before the update.

To answer your question. There is really only one App that I care about and that is my game: Puzzle & Dragons - Downloaded from the Google play store. I purchased the tablet for the express reason of playing this game and now it is the only app that will not run after the update. Every time I start it the screen goes black and returns to the home screen. no error message, just returns to home.

I Initially also had trouble loading my email and my contacts disappeared. But that problem went away after I did the factory reset. Puzzle & Dragons however, the ONLY app I care about will not work no matter what I have tried.

I am not entirely sure what you mean by wipe cache/partition or reset via the boot menu. I might be missing something obvious but I can only access the settings menu and that is where I found the Cache and cleared it. I also accessed the Back up and restore menu and from there I did the factory reset.

If there is nothing you can do from your end, can  you tell me if there is anyway to revert back to the previous OS version? Is that what a "Hard" factory reset from the Driodboot menu does? How do I access the Driodboot menu??

Thanks you for your help. It is definitely appreciated.

Update. I accessed the droidboot menus and did a wipe cache & hard reset. Then I reinstalled my apps and they still will not work. Is there any way that I can reinstall the previous OS? This would be the easiest fix until the problem is solved by dell. What a nightmare I should have never downloaded the new OS. THE APP I CARE MOST ABOUT IS PUZZLE AND DRAGONS. It is the only reason I bought this tablet and now it is worthless to me. 

I am having the exact same problem.  Please let me know if anybody has a solution.

Did you ever figure out how to do this?  I'm trying to revert back to an earlier OS myself to make some apps work.  Thanks!
