Hi All!
Need help. I've got a brand-new brick from my grouper charged with autodroid 1.2 and latest kangaroo v.2.
I had installed kangaroo over Autodroid 1.2 and was testing the fast-charge function while connected through a Y-OTG to a D-Link USB hub with a stick, easycam and DAC in it. All this time it was playing music through DAC. The hub was powered from the tablet as well.
The tablet was draining continuously. The amp.meter showed ~0.75-0.90A supplying from the wall, but if I was opening the battery settings, it was falling to 0.20-0.40A. Strange behaviour, isn't it?
While testing in that environment, the tablet was warm in the left side (I guess the battery is there along with it's controller).
At a moment music stopped playing, and the battery is off. It won't charge by OTG neither by normal cable - amp.meter shows 0A going to tablet. Of course, ADB doesn't see it. Any ideas?
So, does anybody know why this happens: grouper with Autodroid 1.2 and Kang v.2 on it while connected through a OTG-Y to wall charger and D-Link hub (with a couple of devices in it) shows "Charging (AC)" but the percentage is not changing or is slowly decreasing? Voltmeter shows ~5.1 V and most of time ~0.42A. Finally it may completely drain the battery while the percentage will show the same 30-40%.
BTW, when I first plug N7 to the OTG it shows up to 0.90A but if I enter battery settings it falls down to 0.20-0.40A and stays there. Why this?
P.S. I had found that the tablet in my case gets hot because of the chipset.
