I have the same prob...there's no settings of any kind on my storage page. I tried long pressing on everything and hit the menu button but nothing. It pisses me off because ytf would u come out with a phone of not even 3gb of internal storage, And then on top of that u make it where u can't even save shit on ur sd card that you're forced to purchase because not only is it not even 3gb i only have abt 300mb left and that's because the default apps that u cant delete and the OS ..I have a 32gb card though.
I have one last thing I'm going to try...i have the Google chrome internet and just the regular Internet (looks like world) in my regular internet
In the settings under advanced it says select download solution. I'm going to try this on Google chrome...being android is Google, play store is Google, and obviously google chrome..lol I'll be back to give an update shortly...
