[Windows 8 General] NexusRunner:
Hi,

I finally settled with X80h Dual Boot version (Teclast Model ID:FB5M) and I'd like to share my experience.

I originally wanted a successor to Nexus 7 2013 for my family, better equipped with Android 5.0, GPS, ambient light sensor etc... but failed to find a suited one. Seems it have to wait for months. So I think why not try a cheap Intel tablet for a while? The Bay Trail platform seems tempting, hmm...except most of them lack those features I mentioned above.

Then I bought an Onda V820w 16G Win, RMAed once, two models I received both have some screen deficits so I finally returned them. Couple things I should mention:

1. The display is G+P, not G+G It's cold these days, during initial charge the heat generates a fog on the inner side of the touch screen, which lasts for several minutes. I don't have much time playing it before returning so I don't know if it will fog up every time or not.

2. the model I bought is Win8.1 single OS, which is fun but I personally prefer the better touch friendly interface of Android. Onda is releasing a 32GB dual OS version soon, and their OS switch solution is a bit different: you have to run a special app in one OS to reboot to the other OS. They said old model can't update to dual boot. (after all 16G is too small even for single Windows)

3. shortcut key combination for snapshot is not working on Windows, on either V802w or X80h.

4. eMMC seq. write 57M / read 173M. The brand is either Samsung or Hynix, I couldn't remember which.

5. Bosch gravity sensor, realtek WiFi+Bluetooth

6. It says 10 points touch, but again I couldn't remember the brand.

7. Insyde BIOS. Don't know why they keep bragging about it.

Upon returning V802w I saw X80h dual boot was coming out so I immediately ordered one. And here are my findings:

1. Mine is with Toshiba 032GE4 eMMC seq Read 165.0 MB/s Write 72.53 MB/s

2. Goodix 5 Points Touch / Realtek RTL8723BS Wireless / Koinix KXCJ9 Accelerometer / AMI BIOS

3. It's like two separate OS and two separate BIOS share the same hardware. When turned on, You choose which OS to boot, if it's not your last boot OS, the BIOS configure itself for a couple seconds(screen displays BOM configuration switch bla bla bla, guess it's UEFI feature), reboot, then directly boot into your chosen OS. The Android OS has all the partitions like a bootloader (called droidboot), a stock recovery etc. Also when you reboot from Windows, the OS choose screen appears; however when reboot from Android, it boots directly back to Android. Poweroff is also different: if you power off in Windows, the screen goes completely dark, there's no way you can tell the current charge state, and when your short press power button it powers on; when you power off in Android, if it's not charging it's the same as Windows. The weird situation starts when it's charing: the battery animation will appear, and short press will get you to another (different) battery animation. at this time it's all like Android phone, short press=see (the 2nd) battery animation long press=power on, but when you power on it goes back to the first battery animation... I sort of stuck in this weird boot loop for several times before I realized I can always bring up the OS choice screen by holding volume-up while powering on.

4. Due to Windows set RTC clock to local time while all other OS set it to UTC, unless you live in UK, the old glitch of system time drift several hours when dual boot between linux and windows occurs. The workaround is also that old registry hack.

5. Windows C:\ is 12.9G (wimboot) Android /data is 7GB (/sdcard is emulated in /data/media)

6. both OS support OTG, Android doesn't support exFAT. I don't have 64GB TF card to test but 32G is fine.

7. Windows is easy to start with and config, but not so easy on touchscreen. stock Android adb shell is rooted (backdoor?) I'm still reading the Teclast X98 thread on this forum, seems they have a lot in common, Xposed is finally working with the same workaround, but strangely some apps have to initially run with Xposed disabled for the first time or I'd get a system reboot...

15/1/16 EDIT: Xposed is fully working with the X98h hack. That reboot I previously experienced is due to an incompatible module.

8. Mic is really quiet, on skype the other side can't hear me, especially on Android. The X98 sound conf made it louder but too much noise.

After more tests I think it's because the mic is placed physically near both speakers, so during video call the OS automatically turned volume down. The mic hear the speaker louder than I speak! When a earphone attached , the x80h built-in microphone works great, on both OS.

9. I only test it on Windows for a few minutes and I think Battery drain while sleeping is OK, after all even the music stops playing while screen is off. But on Android, just like some common Chinese SoCs, the system can't sleep while keeping WLAN connection, which results 33% battery loss during a night, CPU clocked at 500MHz. I turn that feature off and the CPU finally goes to deep sleep state.

That's all I find out right now. If you want to know anything I'm willing to help as long as I can.

Tablets at this price it's not the specs but the details that matter. So far I see no detail that make it unusable. Actually I'm quite comfortable with it. I should say I'll keep it.

Er... real quick, does anyone know a good tool to check charging current on Windows OR Android? My beloved CurrentWidget on Android Platform failed to detect the current, so I don't know if my charger and USB cord are good for fast charge speed. Both V820w and X80h I bought come with no stock charger in box. They are so cheap that I don't mind reuse an old charger :)
