I bought Nokia Lumia 530 when it was launched as first it worked like a carm, All apps were running smoothly, Pictures taken from its camera was perfect. And Ofcourse Nokia is a trust worthy brand and will always be but In my case it changed my mind about it, I thought Nokia is now specialized in windows phone so there will be no problem in them but Just after 6-8 months, Phone started to hang and games were running slow.
Even dialer took about 15-20 Seconds to open. I got frustrated and I sold it on OLX after a week when this problem started. I would recommend ASUS or other companies that are manufacturing Windows phones. But this phone had an amazing camera quality with low battery backup.
