Hello. I just got my quantum yesterday and upgrade to Mango 7.5. The problem is that i am unable to download most of the apps. When they are downloading i get an error midway saying that app cannot be downloaded since my network is too slow. The internet works without a problem on my laptop. Can this be a issue with the device's WiFi? However, when i surf the web and use the apps already on the phone, they work without a problem. Any ideas?
