Among the call phone company Nokia have the evergreen product from last some year. I am Nokia lumia 530 dual sim about 2 years above and till now it has no diffect I found. I show other brand phone which is more than its value having hitting problem and hanging problem and other some issue after one year or some days. But it has no effect till now.
Its one thing is that it has no front camera and it has no flash light otherwise everything is fantasists.
Its back camera is 5 Mp which quality is good. its screen is good and its look me very cool.
Its support also 3g network and its network quality is fantasists.
I think Nokia is the best brand phone among all the other.
