BLA, 11 Nov 2015Any solution to this problem?try to keep its buffer clean.
david, 10 Nov 2015m4 internal memory have 8gb..is that really enough??For light users it is more than enough with about 3 GB left and also that many apps can be transferred to SD card. For medium and heavy users it is not enough.
Mocca, 11 Nov 2015If u want several apps on ur phone, then don`t buy this one. I totally regret buying this one.... moreTake it easy, I hope Sony will come with more updates to resolve this problem and when they will update Marshmallow to this phone, the problem will get solved. Btw, I also sometimes regret by buying this phone.
bafana, 10 Nov 2015Sony must do something with its phones camera, they are very poor. I did bought this m4 but wh... moreWhat the hell are you smoking?
You had problems with your M4 but the Z series have 20+ MP camera, standing toe to toe with the Lumina handsets.
Guys how is the heating issue now?
Does it heat more than 55 celcius when using mobile broadband?
And does the focusing even slower than lowend phones like e1,e3,e4?
Thanks if anyone can reply.
If u want several apps on ur phone, then don`t buy this one. I totally regret buying this one. I did not notice it only had 8gb :/ It gets full very fast, and I only have 7 apps (Since I cant get more..!). Having difficulties updating them cause my memory is too full. And my phone is starting to mess up and gets hung up so I gotta turn it off every time that happens(often!). Primary camera is also abit too blurry would say. I know that its not supposed to be a great camera, but I got an older phone that takes much more clearly pictures than this. Front camera is allright tho.

But i agree the material used for the phone which is entirely plastic is not very strong compared to Z series.
My friends m4 phone got a cracked screen.
So definitely use a good tempered glass for the screen and somekind of back protection if you buy the phone.
this is the worst mobile. beware of your money . the first day i bought this device was dead and too much heating up. i have given it to service center almost two months gone not yet received my mobile.
every day i am calling to customer care they are telling 3 days or 4 days to resolve every time. but its more over two months i dint receive my mobile.
I cant believe I waited do long for this phone,I got it for cheap too.199.00 US dollars on Amazon.it feels like a toy.The plastic on the back is a very THIN plastic that has some give to it when you press down on it.Easily the cheapest feeling phone ive ever owned.Nice to look at but.

I did bought this m4 but when you compare its pictures with microsoft lumia 640 xl microsoft have better cam and the flash light pic are way below par.i love sony cause they were using better lens and cam like cyber-shot and carl-seiz optics .this G lens it does not do good job at all

Maybe you got a defective peice. Such isolated issues occur in iPhone too. Guys, this phone is fantastic and after the price fall out is the best buy. Heating issues have been solved and the phone is very fluid. Moreover it is waterproof and the screen quality is very good. 2 day battery life for me on moderate usage. On heavy usage 20% remains at night.
