If you read this before you buy a Sony M4 aqua then heads up. It's packed with unremovable apps you'll probably never use. The constant update nags will drive you nuts. Stay away from this phone unless you know exactly what you letting yourself in for.

If you need to store a lot and do multi-task jobs, then you need a mid-range phone.
Anonymous, 22 Apr 2016my battery doesn't last long. not even a day and it's 3weeks old. what could be the problem.May be you need to fully charge for a couple of times, in the start.
Most of the new phone battery is not fully charge.

sorry to say that all the time i am buying sony only but not anymore.At home i have got 3 phones lenovo,lg and sony aqua 4 .it has been observed that it hangs a lot.browing speed is a painful one and camera too malfunction occasionally.so I strongly recommend not to buy any sony cellphones to avoid huge disappointment.

It has a great camera and I like that it's waterproof. But as a phone it is almost completely useless: if you make a call the screen goes blank so you can't end the call. The memory is far too small, and if you add an SD card you can't transfer much of the data or many of the apps, so i has very few other uses. Overall, this is a complete water of money.

Really crap...... Don't waste your money..... Worst phone ever.. Heatup quickly.. Lag alot.. Camera is not good.. Overall totally waste
Anonymous, 10 Apr 2016My sony M4 aqua is not working good too. Heating problem them the camera suddenly stop. What s... moreIf camera suddenly stop working; due to heat, battery level low, memory low.
Heat problem is most probably due to too many apps running.
Don't forget that listening to music &or video would also affect the heat of the phone.
Battery is one of the main cause to increase on heat. Don't charge & use the phone at the same time, as i always see people using the phone while using power bank = Heat.
Feel the phone hot, then stop using the phone for a while.
rosa, 11 Apr 2016that is awesome phone... memory problem will fix with android 6.1 waterproof is superb in ca... moreDo note that not all phones come with OTG.
No need to wait anymore.
If it is OTG, it could work on any Android version.
Also, not all USB cable is acceptable for OTG usage, unless it is specified.
