Worst phones ever. In a year or half your motherboard will be damaged and if you are not under warranty period it will cost you 5000 rupess. And when it comes after repair you will definitely have low battery backup reduces camera quality and degraded software problem. We 5 friends together brought the same and all of us are going through the same problem. And it really costs too much to get sony phones repaired ie not less than 7000.
check your preferred network types(LTE preferred) under mobile networks inside data usage menu. because sometimes it is changing to GSM and other type, hope this helps.

Satyr79x, 21 Nov 2016God, why are so many people complaining? I just bought this last week and has been working gre... moreAlso loved the phone during the initial months...until it broke like the rest. Our experiences are not unique, this phone is destined to break a few months down the line. Wait for your turn.
My first and last Sony phone. POS died after 10 months. The phone reboots in a loop whenever I connect to a charger. The battery drains from 100% to 0% in a matter of minutes. Seller won't honour the warranty but they say its battery related but reading other users with same problems after battery replacement made no difference. It's hardware/software related.
Do NOT buy this phone. Great for a couple of months and it becomes a lemon. Never buying another Sony, worst phone ever owned.
RAFIQ , 05 Jan 2017Plz tell me sony Xperia C4 dual is LTE OR VOLTEIt's LTE not Volte
worst phone Battery malfunctioned after 9 months. Would charge to 100%, but the discharge very quickly to say 90% and switch off. Restart would show 100%, but real state would be 90% or less. This would continue many times until battery fully discharged.
