A tip to anybody buying any android phone - if you don't want to have any battery problems or strange bugs that people complain about after some time of use of any new phone then install CM security, and ONLY CM security, do not install any other antivirus or additional battery management apps like doctor or DU. There is no need for anything extra on your phone for protection and good battery management, only CM security, one app does it all and doesn't slow down your phone. You can add Greenify, don't have to be rooted, just the normal mode to shut down apps you use rarely after you opened them. That's it, other tweaks to make any phone faster are simple and general but you can find it easily yourself.
For those whose screen goes blank during calls..
Jst remove the scatch gaurd from sensors on top of sony label..
At times creates problem, although a very good phone for trained users having ample knowledge of operating an android phone.

One of best phone launched by sony.... Great camera quality of both back and front..... No hanging problem....smooth in performance...battery backup is also good....
Overall...must buy phone :-)
Any body from Sony Listening? I was a big Sony fan but I am disappointed after buying and using C4. Sony seems to basking in its old glory, little realising that a smart phone today is more of an office tool than just a Camera than can call. From that point of view, it is very unprofessionally (rather amateurishly) designed. I have used Samsung, Nokia and LG and they are all feel very professional when using various features. I rue the day when I gave up LG G4 stylus for C4. For example, the messaging screen in Sony is very unclear and sharing a contact number is a headache. Two months after purchase, I am yet to be able to share a contact. Even phone and search features require more touches. Organising various items like Photos, videos and screen shots is again very cumbersome. Sony must upgrade its softwares and provide them to its buyers if it is to save its market.
Hello i am planning to get this phone but i need some extra feedback, i only use social media apps and some apps that is important,, im not a heavy user, do you think its a good investment, i like sony for camera wise since photography matters nowadays,
