ok so here are my observations so far using two android devices, a nexus 10 and a nexus 5, both on kit-kat.
Still takes multiple attempts to connect to camera
No NTP service so have to do manually. Nothing on http://ip_address/eng/admin/adv_lan.cgi relating to NTP.
When app is in background on dashboard no warning notifications appear in foreground.
When app is in background on live view no warning notifications appear in foreground but you can hear sounds in the monitored room. Volume is very low though.
No notification sounds. I can select a sound in the settings, and test, but no sound is played when a notification appears on screen.
Notifications appear to take up to 40 seconds to appear on app and almost always come in pairs, i.e. 2, 4 movement.
If the phone screen locks I have to reconnect.
Android app still "stops" when trying to playback from device. This occurs just as calendar appears.
Android app camera function still does not work when trying to manually take video or stills.
Automatic capturing to micro sd card works and can be viewed from Chrome in combination with latest java plus eu.mydlink.com allowed in the java security.
Bizarrely, if I am charging my android device and unplug the charger, the app crashes. If I plug the charger in, yes, the app crashes.
Two way voice only works properly on the nexus 5. The voice on the nexus 10 drops out a lot, which would definitely not be reassuring to a child. Have tested the nexus microphone with voice recorders/ skype and it appears fine.
I'm sure if you look there will be more issues but I give up for the moment. I was hoping that the firmware upgrade would improve the overall package but I can't see what has changed, at least for my tests on android devices. Hopefully this is a prelude to updated, possibly better, apps, but then maybe it isn't. All I can say at the moment is keep the app up and running in front of you and keep your eye on it. You are not going to be warned that something is happening otherwise. Maybe buy a sound only device as a back up and run both at the same time. Big fail for D-Link at the moment. I am amazed that to have read D-Link was named an International CES Innovations 2014 Design and Engineering Awards Honoree in the Home Networking product category for the Wi-Fi Baby Camera (DCS-825L) and the HD Cloud Camera with Color Night Vision (DCS-2136L). http://www.dlink.com/us/en/press-centre/press-releases/2013/november/12/ces-innovations-honoree. Surely they must have tested it, or maybe they just looked at the specs.
