In the begining sorry for my english
So i have galaxy grand 2 duos (7102), but in aplications there is somethuing missing.
I dont have calculator, web browser, fm radio and many otherts basic things.
I check in ESexplorer path device\system\app, and there are aplications which can not be seen in both, the applications, and widgets.
When i try to install them from that path, there is an error: "application can not be installed"
If anyone had this problem or know how to solve it?
Restore to factory settings does not solve the problem.
problem resolved - warranty
