Hi everyone, it is possible to create a page, just for GSI treble for CHUWI Hi9 AIR ?

Someone to already test :

1) ROM AOSP phhusson ? there are bugs, if yes, which ones ?

2) There are others "ROMs gsi" compatible for (CHUWI Hi9 AIR), if yes, which ones ?

Project treble is just for update android, so :

3) CHUWI Hi9 AIR, ROM of origin or ROM GSI, for the moment ?

Thank you in advance for all answers.

Hi,

I have same issue. When SIM is OFF or WiFi is connected, I have no bluetooth issues.

When I am on mobile data, Bluetooth stops working and headphones disconnect.

I hope next update will fix that.

hi all, I have a problem with the tablet "CHUWI Hi9 AIR".

I recharge my tablet with a solar panel and after 3, 4 minutes, the tablet turns on and stay open all the time.

I put the sleep mode ( NEVER ), but I still have the problem, she charges, but with the screen turn on

I do not know what to do.

Thanks for all the answers.
[Device Reviews and Information] uncleabubear:
Hold the power button until it shuts off.
[Device Reviews and Information] LUYULKMOIO:
Hi uncleabubear, I was wrong in what I meant, sorry.

I tested the STANDBY MODE with 1 MIN / 2 MIN / and / NEVER.

And when I recharge the tablet with the solar panel, the tablet wakes up after +/- 4 MIN and does not return to STANDBY MODE, while she continues to charge.

I want to charge the tablet with the STANDBY MODE, but not with the extinct tablet.

With the power plug it works, the tablet charges with the STANDBY MODE.

With the solar panel, I think that has to do with the variations of the sun, which makes the tablet turn on, but why she does not go to STANDBY MODE, while the standby mode is on 2 MIN, for example.
[Device Reviews and Information] Yeharley:
perhaps charging by solar panel is like always new plug the charger, so it will always be turned on...

[MENTION=5845407]uncleabubear[/MENTION]: Thank you for all your hard work and contribution to help us out. You were absolutely right about the smoothness and the antutu score with latest update.I never got it running as well because i was clean flashing the second update, thats why it was so laggy, once i flashed the first stock and subsequently the second one, there was no lag and i managed to get similar antutu scores as well. EvenPhh-treble only manages 8x,xxx. Thanks again for everything man

I've had no issues flashing modules with magisk so far.

After flashing the patched_boot.img, install magisk manager, then install magisk 16.0, reboot then install any modules you would like
[Device Reviews and Information] Rosetti:
I flashed patched_boot.img. After reboot system was erasing all data. Then I restarted and I installed latest Magisk APK. Then I tried to install Magisk 16 but it freezed and i got a reboot. Its still not possible to install it. Also when I try to install modules it takes very long to install and at the end it says that "unable to extract zip file". Root Checker is OK.

I still have this message when power on tablet that my system has to be erased. (Something like that)

But I still cant flash Magisk 16 because it is stocking at Flashing Boot Image.

Is it because of the message at startup: "Your Device has been unlocked and cant be trusted"? Booting system takes also longer before root.

ALLDOCUBE (M5), Binai (G10Max/G10Pro) and Chuwi (Hi9 Air) are the only budget Android 8.1 options as far as I know (they are all using the Helio X20 SoC). Teclast will probably produce an Android 8.x 10" tablet as well.

I know a think or two about app dev. The problem is that the serial number is not being generated at first boot. You can look at About -> Status -> Serial Number. Something is not right with the build. Most app that support multiple present check that to distinguish between devices of the same user.

[Device Reviews and Information] iuss:
The APK is already included in current phh-treble images.

But even so I had display and touchscreen issues. Root cause is that the original Mediatek firmware rotates the display by 270 degrees based on ro.sf.hwrotation, which is long gone from AOSP.
[Device Reviews and Information] turbotomato:

I have only tried the 180627 phh-aosp build; for me the display orientation was wrong to begin with, so I haven't done much more experimenting with the touchscreen - I don't think I got it to work, so I guess we've got the same experience.

Well, by building phh's AOSP with SF: Squashed hwrotation support applied the display is rotated to the correct position, meaning the touchscreen and accelerometer are correct as-is.

That makes it usable, though the rotation animation is still incorrect. Trying to solve that, but I'm having a hard time grasping the SurfaceFlinger internals involved in rotation. Doesn't seem to be documented anywhere in detail.

Only difference is that glass and touch is laminated together with OGS, so if you break the screen then the touch will stop functioning.

I'm used to alternative android ROMs, but I'm not a developer.

If I read correctly, GSI TREBLE ROMs are generic firmware that works on any SOC,

then to optimize the GSI ROM for the tablet CHUWI Hi9 Air, It will take a good developer.

I would like to help as a beta tester, but do we have a developer for our tablet?
