I buy this phone, first time use this phone always restart problem? and off it self. After I update phone. Still I face this problem. Sound quility is very load and not clarify in sound. Phone is not user-friendly to use. Phone not support Video call properly. Camra quility bad, or seems little bit delicate. Battery backup is vey pathetic and bad. Look and style not comfortable to look. Worst phone ever. Is waste of money.
