Update - 2018-05-30: I have opened a support ticket with Chuwi about this issue. No response as of yet.

Update - 2018-05-31: I received an e-mail response from Chuwi regarding my support ticket:

So, maybe they are working on a fix for this issue, and others. Fingers crossed... :)

Hello, everyone. I received my pre-ordered Hi9 Air from Banggood this past Saturday (May 26, 2018) in the United States, and it is mostly working OK.

Many thanks to uncleabubear for the extensive review and information about this tablet.

A problem I am experiencing is that the tablet is changing the MAC address for the WiFi networking to random values, each time WiFi is enabled.

The first 6 characters of the MAC address are always the same: 00:08:22. The last 6 characters are randomly reset each time I enable WiFi.

I have my home network set up to "white-list" devices with specific MAC addresses, in addition to using WPA encryption. The Hi9 Air is not working well with this setup, as I need to update the MAC address in the white-list each time it changes on the Hi9 Air.

Is anyone else experiencing this issue?

I see from Googling that this kind of issue has cropped up in the past with other phones and tablets. It could be related to recent changes Google has made to randomize an Android device's MAC address when it sends its initial probes to WiFi connections, in an attempt to prevent sites from tracking users. But, Android should then use the "real" MAC address of the device (whether set in hardware or software) when it actually establishes a connection.

I could abandon my white-listing of MAC addresses, as some people say it is an inadequate barrier to prevent unauthorized connections to a WiFi network. But, I live in a less-densely populated area, and I doubt too many people are trying to hijack my WiFi. Using the white-list makes me feel like I have some control over my WiFi setup, even if it is an illusion . :)

Thanks for any assistance.

My tablet preordered from Banggood on 23 April, left Belgium today. Hopefully should arrive in the UK before Sunday when I’m off on holiday!!

Just started a new football manager save on my hi book pro to keep me busy till then.

Fingers crossed for no issues...

My bugs

Does anyone have these problems?

- Power button does not wake up the tablet.

- Screen is brighter in the center area like a rectangle shape.

- FM radio not working

And the well known WiFi off after restart
[Device Reviews and Information] Yesfan001:
Hi, moksone.

For me, the power button wakes up the tablet, and the FM radio works. I'll have to check mine, regarding a brighter section in the center of the display.

Regarding your last point, by "restart", do you mean powering down the tablet completely and booting it from scratch, or do you just mean waking up the tablet after it goes to sleep? In either case, I'll also have to check mine.

I'll reply again after I check these things. Thanks.
[Device Reviews and Information] moksone:
> Power button doesn't wake up... [SOLVED] after a factory reset

> I don't know how to explain the brighter screen without posting an image but I can't cause of the forum restrictions.

> FM radio, what kind of cabled headphones are you using? I tried with a pair of Sony and Samsung, the ones with microphone… without success.

> I mean reboot completely.

I am scared for the screen and scared to write to banggood customer service, does anyone tried to contact them for a problem like mine? I mean "change the tablet because is defective and the quality control team was sleeping " kind of request.

I got the power button issue too! pretty annoying…. I might try a factory reset

Chuwi Press Release.

Dear customers,

We thank you for your support greatly.

The announcement below is a bit explanation about the GMS certification on our HI9Air.

As of today, our branch has contacted Google to obtain the GMS license, and permit will be granted by Google in early July, on which all our Hi9 Air devices will receive update through OTA.

The current Hi9 Air devices have access to all the normal Google apps since Google has provided us the consumer permission until we are finally certified in early July.

Sincerely yours

May 25 2018

FM problem solved

- FM not working [SOLVED]

I managed to solve the problem with my FM radio. It was an hardware problem, a defective 3.5 mm jack socket on tablet.

SOLUTION:

DO IT AT YOUR OWN RISK, I AM NOT RESPONSIBLE IF YOU DAMAGE YOUR TABLET.

You have to remove the SIM/microsd/camera cover, insert GENTLY and CAREFULLY a flat screwdriver between the case and the first golden pin of the socket to use it as a lever to bend slightly ,VERY GENTLY, the pin towards the inside of the socket. I used a SL1.0 screwdriver.

Practically the pin wasn't making contact with the jack plug. That's all. Bad manufacturing.

I am working on display problem, it seems to be a glue problem between the digitizer and the screen, it is resolving by itself with use. I'll keep you informed

Update 2018.06.04

Just contacted Banggood for the display problem, it turns out they will replace my tablet, I have to send it back.
[Device Reviews and Information] DanteXXL:
Received my tablet today and it's very laggy, anyone has the same problem?

It's on the latest update but the scrolling is not smooth at all, and watching video is almost impossible because of how jittery it is.
[Device Reviews and Information] YuriRM:
Try a factory reset.
[Device Reviews and Information] DanteXXL:
I did and nothing changed. It's not bad when used horizontally, but whenever I hold the tablet vertically it starts lagging.
[Device Reviews and Information] THFourteen:
Which apps are laggy?

I got mine yesterday and so far its been really fast and responsive. I disabled the animation in developer settings, maybe that's why?

Using Nova Launcher and Chrome. No noticeable lag on either.

Must say I real love this tablet for £160 absolute bargain. Screen could be a bit brighter but its still useable outside so all good. Haven't tried 4G yet but WiFi is nice and fast even though it only shows two bars.

Main gripe is the screen protector which is awful. Need a tempered glass one but can't find one that fits.
[Device Reviews and Information] DanteXXL:
It's not just one particular app but the whole tablet, scrolling and animations were sluggish whenever I use it in portrait mode.

Twitch was a bit laggy as well, it's not even as smooth as the Fire HD 10 in my drawer.
[Device Reviews and Information] madsurgeon:
I've had my share of Android tablets, and the Hi 9 air is by far the best among them. It's very about smooth and fast, the install time for any app/apk is stunningly fast.

Installed and running phh-Treble. Everything is great except for the accelerometer/screen rotation no bug, which I've curb circumvented with a rotation control app. No other issues to report.

I got one of those 360°universal 10.1"tablet cases, not very impressed with the fit and not stable in landscape mode, have ordered the one from BG posted few pages back.

Thanks again guys for all the reviews/tutorials and support. Cheers!!
[Device Reviews and Information] YuriRM:
First disable animation in developer settings as suggested. Then consider the possibility of malware in your device.

My suggestion is to install the beta version of the Intra app by Jigsaw Operations LLC (an Alphabet company, the owner of Google). It provides Private DNS over TLS. You can find easily which apps are calling back to China or elsewhere.

https://play.google.com/store/apps/details?id=app.intra

How to Get Android P’s ‘Private DNS’ Mode on Oreo and Nougat

https://techtrickz.com/how-to/how-to-get-android-ps-private-dns-mode-on-oreo-and-nougat/

You can also check with NetStat

https://play.google.com/store/apps/details?id=com.rinacode.android.netstatplus
[Device Reviews and Information] DanteXXL:
Already tried disabling animation and it's still sluggish.

Followed your instructions and there were DNS requests to several questionable sounding addresses like yiqiziku and taobao, but I'm not sure if they're just ads or malicious malware.

I bought this from Chuwi official store on AliExpress, should I contact the seller or try to get in touch with Chuwi for warranty? Although chances are no one will take responsibility for this.
[Device Reviews and Information] YuriRM:
Try first the NoRoot Firewall by Grey Shirts

https://play.google.com/store/apps/details?id=app.greyshirts.firewall

Allow only the apps that you need and trust based on the Intra and NetStat results.

Run a few Antivirus apps too!

EDIT- you can submit a ticket to Chuwi. Elsewhere in this thread there is a link to it.

EDIT2- get a new launcher. Nova launcher and Chrome have been suggested.

Alberto96, you will not make any more ROMCUSTOM for the chewi Hi9 Air ?

I have one with latest builds installed and I am not happy with SW quality. Mine also has problems with wake up from sleep mode, i have to reset to factory mode to fix it and i am not sure whether this problem hits the device again, but i think so. I also problem with scrolling performance in browser, youtube, etc., it is not smooth as expected, but this issue i accept, unacceptable is vsync problem because renderer scatters horizontal lines when scrolling.

Nice rom!

I have one problem though:

when I want to add an additional user to the tablet (for my wife), there is no keyboard to enter the account details (Google account + password).

Any ideas on how to get a keyboard there?

Note: the keyboard works well for the primary account (my account).

On the site https://www.needrom.com/ , you have to pay, Why ?

I still do not install the latest firmware 20181123, because I find it weird, that the firmware is not on the official site of chuwi.

Does anyone have an explanation to this ?

From Facebook 7 October 2018

All CHUWI tablets with Helio X20, X23, X27(or higher verison) will be updated to Android 9.0 in 2019 (edit Chuwi is not updating to Android 9)

I tried incremental system update from OTA Wireless Update Stock Rom Build number O00623 release-keys 20181010 but it results in some typo problems, but without impact to functionality.

Then i flashed Stock Rom Build number O00623 release-keys 20181122 today and i did not notice any issues yet. I subjectively feel some performance gain and it also looks that device can play louder then before.

[Device Reviews and Information] LUYULKMOIO:
Hi amg314, I downloaded the new firmware Version 1122, but I will not install.

Why the firmware Version 1122, is not on chuwi's site ?

I will wait android 9, before reinstalling a new firmware, hoping it will be on chuwi's site.

For the moment, it I stay on the version 0809.

Well done for getting to 1000 posts everyone.

For all it's faults and a pretty off hand Co. in the name of Chuwi, I am still mostly happy with this slate.

I have not replaced it with something newer yet so it must be good enough for now!

Is it possible to upgrade from V2 to V3 Gearlabs ROM? Or do I have to go back to stock ROM first how Alberto mentioned?
[Device Reviews and Information] ivanfix:
With latest stock, sometimes, power button does not wake up the tablet.

I have already done the factory reset…

Does anyone have the same problem?
[Device Reviews and Information] fasty:
Yes, I had the same problem. In fact, every time I have done OTA update I get this problem.

For me, factory reset has fixed it on previous occasions. I can only suggest to you to try it again.

Mine is OK at the moment, but I shall not be confident for weeks.. We know that this problem can return after a few days.
[Device Reviews and Information] amg314:
I have heard about 'Power button' issue with other 4pda.ru users.

My experience on this: I caught this problem while playing with the Xposed Gravity Box on August ROM. Factory reset fixed the issue)

That is why I am not hurry to switch to the latest firmware versions.
[Device Reviews and Information] FrenchSparda:
Still happy with mine, simply perfect for the use in my car (music over bluetooth, waze/maps). Except the issue with my screen, no other issues so far. Too bad there's no kernel sources. Once i'll receive my new SSD, i'll try to build a GSI lineage new ROM. Too bad there's no kernel sources, i would love to have D2TW feature ln the Chuwi
[Device Reviews and Information] LUYULKMOIO:
FrenchSparda, even though we have (kernel sources), we would need a developer like "Alberto96", to make a good firmware.

The GSI, can not be possible, that if we have the source code.

Is this the latest official update? My one has build number 000623 release-keys 20180616. When I try to update via wifi it says tablet is up to date.

Where can I get the latest firmware?

[Device Reviews and Information] orbec:
My Chuwi no longer appears in my devices list on the Play Store since the latest FW update!
[Device Reviews and Information] FrenchSparda:
Where is the kernel source code ?

Chuwi is treble compatible, so why do you say buiding a gsi treble ROM isn't possible ?
[Device Reviews and Information] LUYULKMOIO:
French Sparda, GSI treble is ( os generique for all SOC ).

There will be no GSI treble compatible at 100%.

(kernel sources of chuwi hi9 air ) + developer (Alberto96) = GSI treble personalized for chuwi hi9 air.
[Device Reviews and Information] rippledrums:
Does anyone know if the existing TWRP in this thread also works for the newer Helio X23 version? I'm close to ordering one and would like to know that.
[Device Reviews and Information] Gumka1977:
Yes, works with magisk. For full service you need to decrypt partitions.

---------- Post added at 11:26 AM ---------- Previous post was at 11:02 AM ----------

Evidently we need Alberto96's support for the GSI project for our miracle Hi9 Air (Alberto, please!). Many editions are already working on other devices (see also 4PDA).

I am looking forward to doing something with impatience.

Hello everyone,

I´ve sent a message here earlier about constant crashes on august ROM because the fota.application thing but now I got my device updated to 20181122 updated via SP Flash tool and everything went well on update.

But after a couple hours first crash happened I noticed a Play Protection notification which told me that it has disabled Font Manager app because " The APP can allow unauthorized access to your data or device"

And right after that the device rebooted again.

WHAT TO DO!? I´m getting desperate with this tablet as before I´ve liked Chuwi tablets and owned a couple of U64G tablets and was about to order 2-3 of there Chuwi Hi9 AIR tablets but it this is the case they work, I most certainly won´t order more untill this is resolved.

Ctrl+C to break logging after your tablet will reboot spontaneously.

2. Or use adb command

adb logcat -> my_log.txt

3. Use CatLog app
