the Hi8 Pro Dualboot has a deep sleep problem (SOD - Sleep of Death) on Android.
Let me explain. If you use Android and the device gets into deep sleep/deep standy, every time it doesn't wake up when pressing the power button. I am not 100% sure if it happens on Windows, cause i don't use Windows much.
You have to do every time a hard power reset (Holding the Power button more than 10 seconds).
The problem is reproducable and highly discussed on the techtablet forum.
It is not possible to do a usable logcat to locate the problem. If you use the power chord, the tablet does not enter deep sleep mode.
If you do a logcat only on battery in a terminal APP after the crash, the logcat is empty, better said the old entries are gone and only the new entries are present after the hard power reset.
There is a workaround, using the APP SOD Killer, but you will have much more battery drain over time, due to the tablet not entering deep sleep mode.
It is not a Workaround to do a Hard Power Reset every time!!!!!!


Please contact your developers to try to solve this problem, because the tablet is not usable at this state.
I can speak for all Chuwi Hi8 Pro Dualboot owners/users that we are very disappointed that this device is sold with a defective Software/firmware and Chuwi does not recognize it.
We spend a lot of money for this imported device and it's very expensive to send it back to the reseller in China.
We would be very grateful for a quick solution.
If you need logfiles or dump files, please show us the steps how to do it. We are willing to upload the logs, so we also can help you and speed up the process to eliminate the problem as quick as possible.

Best regards

Hi, I had the same problem, I had to wait some minuts to get the tablet turned on. During this time I put it in charge and the light was on, but now even if I put it in charge the light is off... Since it is 2 days off, I am afraid it is dead! Do you have any solution? (I'm so furious, I saved lot of stuff there...)

I have the same issue (as have many people on the tech tablets forum). I'm hoping for a fix from chuwi to make Android usable on this device.

I do have a work around it seems.. go into the advanced settings of the wifi and set it to be always on. I think that the wifi module is slightly flakey when turning on and off. Hope this helps someone.

Same issue, worst of all, the product I bought here is not returnable or refundable. One week exchange window, it's gone. The problem is a defective design issue, every device they produce has the same problem until they can fix it before they sell it.
