I am requesting some info regarding wifi behavior from DNA owners. I currently have an Inc4G, and am contemplating upgrading to the DNA. However, I want to be sure that a particular behavior that the Inc4G and other HTC phones has regarding wifi is not present in the DNA prior to pulling the trigger. On the Inc4G (and other HTC pones), wifi goes into a sleep mode a few minutes after the screen goes off, regardless of what settings you choose. It does not come out of sleep until the screen comes back on. It does not disconnect, but will not transmit or receive any data. Since the phone will not use cellular for data when connected to wifi, no data is sent or received during this period. This leads to delayed notifications and issues with any app that uses background data. It does seem that the wifi will wake periodically and notifications will come in, but they are delayed, anywhere from 5-15 minutes, generally. The two main apps where this is the most noticeable is WhatsApp and TouchDown email. I use Exchange email, so delivery to my phone is real time. I would receive an email on my PC, but the notification would come later. However, if I turned my screen on, they would all immediately come in. This made it obvious it was an issue with the wifi while the screen was off. If someone could test this for me on the DNA, I would be extremely grateful. This is my biggest frustration with the Inc4G, and do not want to deal with it on another phone.
