I have a bit of a strange issue! I am using the preinstalled OS 4.1.2 and when i got it, everything worked fine. I bought this in the UK before christmas and i live in ireland. I was asked to do an update, which i went through - at one point, it stated that it was not completed sucessfully (can't remember the message exactly) but when i left it work away, it completed and restarted as normal. Since this point, i cannot use Google Play Store. I get error 406 whenever i try to install anything new or do an update of any application. I have ruled out an issue with the gmail account as it works on other android devices. I even setup a new one to see if this was the issue but it made no difference.I cleared the cache on the tablet - no difference. I did a reset of the tablet through the Settings - no difference. I booted to the boot menu and did a factory reset - no difference. I tried downloading apk files using the web browser and although i can browse the internet, when the file downloads - i get "cannot open file" I have checked and checked the box for Unknown Sources in Security - no difference. One thing i have noticed is that if i look at the Google Play application, it states 0.00KB for its size which is obviously not right but i can do nothing with it.No option to clear cache on Google Play. I tried alternatives to Google Play but again, i cannot open the files. I have now tried rooting the tablet which has worked but i have the same issue. Any ideas on how to resolve this?
