Just thought I should share this hopefully it will give people advice on the hopeless phone called the Sony Xperia M4 Aqua. The phone is a nightmare with sony not really giving a dam with its faults from new it has had a problem with the camera now if you have this phone it will tell you that the camera is not working, this is a major problem with the sony xperia m4 aqua (just look at the Sony forum). Vent over now if you have a phone like this make sure you have a PC/Mac as you will be using the PC companion software a lot my phone has had the repair program run 8 times and still has problems with it. If only I was not locked in with this phone I would change to another.
I have the M4 Aqua, It has a variety of faults that range from heating up to like what you have said about the camera which is probably one of the worst I have seen, The video is a waist of time and has focus issues, It cannot function properly in any low light situation, I am finding memory to be a problem and sometimes whilst in an app it jumps out of it, The keyboard is a bad experience on this device and have experienced lots of lag, I think an update to enhamce the camera and video will rectify that problem, The processor is why the back heats up the only way to get around this is not to play games on it, Overall I am not happy with this device whilst it does look good I think the handset should be removed from sale until it works as it should, At this time the handset could set you back £170 which is a disgrace as it is not worth £5.
I have the same camera faults,it will not store at all - just a little pink line going round and round. Not able to take video and mine keeps saying the storage is full and move to SD but it doesn't let me! Bought a new SD card and still it doesn't let me. It now boots my off apps as well. Funnily enough my partner has the same phone and CAMERA PROBLEM with his phone too!. I've had mine since Nov 2015 and he since Jan 2016.
I sent mine into Virgin as it was still in warranty but they didn't fix it, not even sure if they looked at it! Instead they sent my phone back saying there was a crack in the case and that had invalidated the warranty. They also said if I wanted to pay £66 to fix the crack they would then sort the fault. Ha ha that's funny was my reply and...as far as I was aware there was no such crack. I told them I wasn't bothered about a crack and that I hadn't even seen it. Asked them to just sort the phone as it had been getting worse for months, they said they couldn't repair the fault unless I paid £66. I said no because that wasn't the problem, they sent my phone back.
On receipt of my phone I immediately searched for the crack and surprise...NO crack to be found. Passed it to other members of my family and NOPE, they couldn't find the crack in the casement either...hmmm. I'm thinking - cop out by Virgin. I have however found a small scratch on one corner only - which was a surprise as the rest was perfect as I'd always kept it in a case.
I phoned Virgin twice this evening ( on a borrowed mob ) and asked for the Technical dept email address as I have no phone during the day and that dept is closed when I get home after 5pm. TWICE the phone was put down on me when I said I didn't need to give them my details as I was asking for email info.
Two phones with the same problem !! I AM taking this further
Similar faults with heating up on mine. It was still in warranty but Virgin wouldn't fix it. Instead they sent my phone back saying there was damage to the case and that had invalidated the warranty. They also said if I had to pay £66 to fix the case before they would sort the faults out.
When I sent it I KNOW that there was no damage to the case Now there are four ridiculously small pinpoint pressure marks (in a rectangle) with radial thread marks - bumps UPWARDS coming out of the surface of the phone. I feel conned so I'm not paying £66 in principle and will revert to an old phone. I do wonder what trading standards experts will think about it when I show them the bumps on my phone.... Well what else can you do?
Also had problems with this phone super heating when charging. Virgin said they would fix it, charged me twice to have it fixed due an administrative errors then sent it back and said the crack in the phone was the reason it would no longer work. There was no evidence that the phone had been examined. I suspect that it was a simple case of not wanting to replace as it sounds like the overheating is a common issue.
It is a shame as I really liked the phone and thought the camera was good
