I have used this since last five month here, I say why this is not best, and why it is better this is because when I started to use it. I felt very good but one day. Please read this before you buy while I was browsing through the many websites. it suddenly started to vibrate continually about one to one and half hours I dint understand what is going on I got astonished , I didnt know what to do I took my another mobile and started to browse through about this that why it is vibrating thank god it gave me answer that keep on pressing the volume button and power button so it will be cleared so I did like that it was normal but every other things are worthy and best , mobile was fully charged I thought it will blast I was panic. I suggest my readers not to buy China models I future. Thanke you for reading network is very good , customer service is worst idiots they will not available on festival days, is there any rule that my phone will not spoil in that day. , charges are OK.
