I brough this product at 2013 at approx 4k price, frist time its works really good.but after 2 months, I see sometime memory card automatiacally removed.so I re connect that memory card, then memory card working good.suddenly one day I saw this phone is automatic on and off.that mean auto restart.then I go service center they solved this problem but take 7 working day.to much time.now arrived a new problem when I connect the charger, then blink "charger connected" on screen repeatedly.Screen touch is very hard.so overall this phone is not a good phone.its very bad.
