Working superbly than samsung phones I had used two android phone which sucked up me but this phone is better then those.works perfectly no strucking and simple for those who want to buy a phone under 9k, amazing apps, graphics.but the only problem is thet no sefliee, no cortana.its just simple smart and short.it has 8gb internal memory and external memory only single sim.so why late guys go to your near by store and get this phone.
