its possible to return to previous software before update because new update battery discharge very fast
If you buy your M4 in South Africa it wont have any problems because they were tested before they were released so there is no factory defaults mine works perfect
I'm using this phone since one week.when I charge my phone more than 2hrs then it hangs I'm not satisfy with this phone
Indeed the heating issue is horrible. Camera is barely decent and the battery life is so bad. Only good thing is the water proof function and the light weight. Design sure is nice but catches much fingerprints.

humi, 13 Aug 2015Hi;I would like to know how long does the battery last on the M4 Aqua;according to the box it ... moreBattery life is greatly dependent on how you use your device. With heavy usage, it will only last for a day. With stamina mode and average use, it can last for 2 days.

I've been using dis phone for two weeks I returned it a week ago I had a problem with the speaker people can't hear me when I answer a call, even after repair it's still doing the same thing they said it because of poor signal, any1 with the same problem?
I upgraded to Sony Xperia M4 Aqua but had an isue cause it wont charge so had to take it back. It was replaced with another one which I have been using for 4 days until it just shut down with more than enough battery life. I put it on charge anyway but nothing. After 3 hours of charging still nothing. The charge light is not even on but the phone is warm from charging...its completely dead...nothing is happening...now I have to return my second one to my service provider. I fell inlove with this phone when I saw it the first time but I'm definitely not taking a 3rd one! Major factory defects! I had a sony xperia M before this one and had no issues for 2 years...but this is such a disappointment!
