The update is not so good but there are some changes in the UI the icon size can be changed
But there are more disadvantages in the update
When you restart your mobile phone which is in silent mode it automatically change into normal mode when it is switched on
Phone is getting heated when it is continually used
Totally THIS IS AN WASTE UPDATE
Dolly, 05 Aug 2015Aftr update no applocks working.pls fix the issueyup ur ryt bro... really f***k up sony Aftr update no applocks working.....pls fix the issue
This phone does not support pendrive plz check specifications . Heating of phone is not a issue. All octa core phone heat it's not only sony's. Htc n Samsung also heat
When i am on call if i would need to note any phone number we need to open up the dial pad.
at that point of time if you mistakenly type any number there is no "BACKSPACE" available to delete the number. Is this a BUG in Aqua M4 dual.
