I've been using android since 2012 up till now, and I've changed my phone almost every year.
The phone if somehow fluildly fast in the first two big update and became extremely slow throughout the year.
The pro's is for those who frequently used SD card storage find it very useful (Files, document, emergency pendrive, lanun music and other)
Xperia S (1yrs) -> Samsung mini something (couple of month) -> Xperia T2 Ultra (2yrs) -> Xperia Z3 Compact (almost 1 yrs/current)
Experience with android phone is Screen replacement problem, Flap glue dried, Lag during emergency situation(call/navigation/etc), slow update, unpromised advertisement, bad customer service,etc.
People who used Iphone seldom change their phone every year and might still hold it onto them for 2-3 year. this one i very butthurt.
This is the reason i changed to iphone.
have been using my 4s since 2011 dec till now and still working good, main reason to change now is because of 4g, camera and battery life, so can say ios device is really not bad in quality
