I have a U25GT-C4W running Android 4.4.2 KitKat. I have managed to root the tablet.
The tablet has a separate charging DC 5V in jack as well as a USB Micro OTG connector. It connects to PC fine and I am able to detect it through adb.
It is also able to detect OTG devices connected to it such as a Keyboard, Mouse and a USB Stick/Flash Drive.
Out of all the China tablet clones that I have tested, this one has a peculiar behavior. See picture attached to understand this behavior.
If I connect DC 5V plug to tablet, tablet starts charging.
Then when I connect a USB Mouse, the tablet STOPS charging after 5 seconds (Not normal behavior).
Then when I remove the USB Mouse, tablet starts charging again (after 10 seconds).
I have tested other tablets with separate DC 5V jack and they do not show this behavior. This is not normal.
Tablets I have tested:
ValuePad VP112
King's Hong Kong H704A
When these above tablets are charging with DC 5V, and then I connect USB Mouse, these tablets do not stop charging like the Cube U25GT is doing.
Has anyone else experienced this type of issue? Has anyone solved it? Are there any custom kernels/system that I could use for this to solve the problem? I don't usually post questions on the forum because I usually find the answers I need after searching for a while, but this has been a baffling situation.
Hopefully someone will answer. Let me know if you have any questions about my issue.
Thanks.
