I bought a sonyc4 model January 2016, everything was alright till the 8th month of the phone. I started having touch screen issues. I brought the unit to Sony service center makati first but they told me it would be quicker if I sent the phone to Sony pasig. With that I brought the phone in pasig and they diagnosed the phone to be having ghost touch screen/touch screen malfunction. Luckily my phone is still on a 1 year service and parts warranty. And luckily the necessary parts are available at the service center (some we're not lucky because they have to wait for a month or two before the parts arrive). Indeed, my phone got fixed but for how long will it be OK??? Im saying this because on the day I received my phone, there was this customer who only had his c4 for 5 months then tochscreen malfunction, sent to Sony pasig for repair, then after 2 months touchscreen malfunction once again. Also out of 10 supposed customers who went to the service center for phone repair almost 7 of which possess a c4 model. My point is, Sony should recall all c4 models and replace it with other model handsets. It's not OK for us customers to think that anytime out phone may breakdown .

so far so good when I update my sony c4 to 5.1 , i think it depends on how you update it there many things to consider to have errors and problems after updating the unit.
since 5.1 update touchscreen problems, dont update to 5.1 remain on 5.0, using custom room fixed problem
About one in four calls, I can hear the caller but the caller can't hear me. Problem persists until the phone is rebooted. (Fortunately it reboots fast.)
Hands free randomly turns off during call, usually when screen sleeps.
Answering machine app freezes the device from viewing or making calls and texts for 2-5 minutes after taking a message.
Other than that, it's OK. I don't dare update the software in case it makes it worse instead of better.
this phone is piece of crap. switch offs automatically and will not start till you connect it to the charger. severe touch problem. Touch at some point of display and it gets automatically pressed on other parts of screen. evan can't unlock the phone. 1 cm of display at lower side is unresponsive to touch. Don't buy sony phones.

I bought a Sony Experia C4 and used it for one month after which I started having problems with the camera. Whenever I tried opening the camera application it couldn't. Instead it showed that the camera or flashlight was in use by another application (which was not the case). I honesty though sony products are genuine and quality but I was proved wrong by that awful experience. I ran at a loss by this phone.
bhagwansable, 16 Jul 2016Worst phone ever i had use. Its come with touch screen problem and sony know it that Xperia C4... moreI absolutely agree. Sony also promised about updating this device to Android 6 and skip Android 5.1 but now it is in Android 5.1 and it seems that they do not update for this device anymore. They do not tell anything about touching issue. They ignore consumers. Do not buy any Sony products. I also understand why my friends and people in my country stop buying Android Sony phones. They made it very bad with over prices but warranty is very worst.
If there is any touch problem, thats because a software bug, I have also faced to touch problem, so after that I put my phone to safe mood,still I didn't got any touch issues.. Try it guys!update with android marshmallow bugs fixed.. Still not yet released, This phone is good device, I can satisfied with c4..
sony xperia c4, one of the worst phone ive ever had, same problem with the others, overheating, touch screen dont work, fast draining battery. what the heck. . . im so disappointed with this. . .
Nick, 05 Aug 2016Do anybody face this problem,all of a sudden Sony C4 is getting heated???Yeah.... It gets heated and also runs fast out of battery
