Ive been using this phone for almost 3 years, the sound is still pretty good as it has the dual front speakers. The phone is a bit laggy sometimes but I have no serious issue with this phone. The phone is updated to android marshmallow and the user interface is great. The best thing about the ohone is its camera which is really good and still works great with great quality pictures. The only thing which is an issue witg this phone is the battery life which sucks to the core. I have to charge the phone twice or even thrice a day. But even after 3 years the phone is pretty solid and gets the job done
