The lock feature is a saftey/privacy mechanism so that someone doesnt use your phone if unattended. Kind of like a screensaver if you want to use an analogy. Windows continues to run in the background and outlook continues to download emails despite your screensaver protecting your system from prying eyes or loose unknown fingers. Simple procedure--- if you dont want to run the DLINK app then shut it down. Also, YouTube videos have fixed duration and do not represent a continuious connection by default as does viewing your cam remotely. I think it works for its internded purpose and is designed properly for normal usage under normal circumstances. I suppose we could ask DLINK to make it an option to close the way you want for special situations.
Sorry, this is a mobile app, not a desktop and it needs to take bandwidth and the mobile restrictions around using a phone into consideration. There is zero warning this occurs after a phone lock. Zero. It drains your battery and sucks your data dry. This is simply a bad design. They designed it like its a desktop app, and shouldn't have.
There is zero benefit to keeping the stream going as you cant rewind.
So why not just make the application "pause video stream when phone locks or user hits the home button"? Seems simple enough and prevents this from happening. I have never seen an app eat resources like this after a phone lock. It's clearly an oversight by dlink.
No application should ever use your battery and/or data when not physically being used.
I would really like someone from dlink to comment.
