Hello, When I tried to update my tablet I went to the play store and to my apps then to update all. That is when I got the message about the file. I was wondering if one reason is that my tablet is running 4 .21 instead of 4.22 like my phone. If that is the case then even though, I just bought the tablet in July it might allready be out of Date. Is that a possible? Thank you in advance, Bill Deatherage
