I'm using samsung galaxy A5 since months. It has never caused any trouble.
pros are as follows :
Picture quality is excellent
sound quality is good too
Latest android version 6.0
Long battery life
has niceuser interface that is easy to use even when I used it forst time ,
its total value for money ,
cons,
built quality could have been better,
fast charging is missing,
could increase inbuilt storage , and memory card .
better optivmcal stabilization could be a nice add to the phone itself
overall I recommend this phone as it is total value for money
