Smartphone with smarter UI, ambient light sensor works well specially in light, fast charging is not really fast takes two and half hour to get fully charged but lasts long and that helps a lot. Fingerprint sensor works perfectly and more better than galaxy a5 2016(my friend owns one and had to take a pic from another phone). All apps open quickly and no lags and no error messages till the date.
if you want sound quality and fast action than I think this is the best mobile. you need to use it first after you can feel that how you found in this mobile.
