that's why i can't wait to get a hold of Z10, when it becomes available in the Us. i plan to sale my S3 and get the Z10. i am getting somewhat bored with my S3. its quick battery drainage also frustrates me. i really like its Personal/Work feature, along with other cool things, that isn't available on the my S3 phone. i am getting more concerned nowadays after downloading free apps on my S3, as who knows what personal information is stealing from my phone in the background.
Try the App 2x battery saver. It has increased my battery life double throughout the day. It does this by intermittenly turning off the 4g radio antennas and unnecessary background apps that are not actively used.
Yup with android say goodbye to privacy that's the whole point behind open source software, i just cant wait for it to come out here i was thinking of buying one on ebay but they go for insane amount of money so i am gonna have to wait too till its available here.
