Now am using this phone. Have a good look. And very slim. It having a 4 gb ram so there is no issue of hanging due to overstorage of applications. And also its having a 64 gb of internal memory. So no need of external memory card. Although this mobile has a 128 gb off accesing a external memory. My mobile having the excellent battery back up I can use over a day by using internate on it. And only for a calls, it can sustain for 2 days The mobile has a name of motorola so its a brand for the android phones.
