Hi guys first of all I'd like to tell that i have been a Lumia 520 user for 2 years now. I got it the day it launched. It was my first phone. I love everything about this phone and the WP OS. But the only problem i have is the "App Gap". I don't mind apps like snapchat but there are some others that i use which are not available. I want to buy a mid-range phone and narrowed in on the HTC desire 820. I want to know if it's a good phone and how are HTC's phones in general? I trust this community and that's why wanted to ask from you people. Please provide your opinion.
