Do not purchase M4 AQUA ever.
I regret. it has a list of problems. and sony customer care support is worst.( I visited sony support center @ gomtinagar. executive there were really unmannered rascals).
I have purchased it in january 2016. ithas started showing problems from the next day.
The phone has following problems:
heating issues ( means it gets extremely heated).
battery gets drained out within 3 hours ( I must tell u that I have taken all measures like switching off nfc, wifi, BT, sync, internet , uninstalling facebook and other battery hungry apps and switching on power saver mode).
automatically gets switched off and on4. hangs alot5. charging problem ( it usually gets automatically off withing 3 hours andwhen u plug it with its charger it do not response 20-30 mins.
And then shows 1% 6. charging time. ( it takes 5-6 hours if u switch off phone and then charge.if u try to charge it while switched on, then it would take around 8-10 hours.
