From last few weeks most of the apps (whatsapp, IMO,windows central, YouTube, etc) are not running. I have hard reset several time but result is same. Help plz. I am using Microsoft lumia 430.
Mate, that is too much load on a budget device that is 2-3 years old and has an old processing system. these apps are constantly updated and I just feel your device is too outdated to function properly and give a superior performance for all these apps which are optimized to run on high end devices. Get a Lumia 950 on ebay or amazon.
