Alright. Same friend. A smartphone for his dad. I suggested Nokia Lumia 620 largely because it is harder to mess up (no icons or widgets!) and is easier on the eyes (larger buttons and text).But my friend wants WhatsApp to work properly on the phone. Anyone here has a Lumia 620? How good does WhatsApp work on it? I keep on reading about problems with it running in the background? Is the problem solved yet?Otherwise, he would get Micromax Canvas HD for his dad.
