Now the Chuwi Display on Android is Sharp!

Wow guys I can't believe what I've found for the blurry display on Android. I've been searching high and low to find the fix for this problem.

Lo and behold, I finally find one! And it's not a solution for Chuwi but for a Lenovo product.

Just download the apk, install and enable the Switch off blur filter in it. Now your dislpay will be as sharp as when you use windows.

You can google it "Yoga 2 Sharpness Fix".

Share your experience here too OK?

Now I'm searching ways to adjust the hue and saturation for Andoid...
[Device Reviews and Information] LuxZg:
I've planned to do that, but by the time I found a tool to make the image I've already put some of my own data on it. I'm planning to make some upgrades/updates (Win 10 for example), and I plan to try to do a restore of that Macrium Reflect image, as well as Refresh of the Windows. I'm just waiting for an USB hub that actually works, as I had huge troubles making this one image I barely succeeded to make, just because of USB hub. So for now, I won't be uploading anything, but if I make a refresh, I can also make a factory reset, remove all my personal data, or whatever, and than make one image with KitKat+W8 Bing (as originally) and one with KitKat and W10 (after upgrade), and I can than upload those two. It will take a while though, I'm still waiting for hub, not sure when it will arrive.

First off, I wanted to try this right now, but ended up opening my Chuwi instead. Tried to wake it, but was dead, and would not charge. Since I've already read that it's easy to open, I took one of those plastic phone-opener tools from old Nokia dumbphone days, and removed the mask, unplugged battery, waited a bit, and plugged back in. Now it's charging and I'm just rebooted to Android. I'll try it in a minute and will edit this post. I'll also make few snaps of the insides but will post that some other time.

EDIT: I've downloaded v1.2.1 from XDA thread and 1.2.2 from GIT page, if that's what you used... but both APK files say "can't open file" after I download them and try to run them on Android on Chuwi

Are these the links for Yoga fix that you've tried? Is your Chuwi rooted?

I bought one of those USB OTG hubs with charging-while-hosting capability ( http://www.ebay.com/itm/171910156352 ), it's probably from different seller than others I've seen mentioned, but by images it looks as same device.

Others reported that they got it working by cold-booting to Windows while hub was in "Charge" mode, and it was charging, but Windows would recognize USB keys and whatever connected to USB hub.

Well, not in my case. Any other suggestions? I've tried few things I could think of, but it's always either charge or USB-OTG hub.

OTG hub part works fine on it's own, I'm currently doing another backup on it (keyboard+mouse+USB stick, booted, recognized, copying data as I write here).

Charging also works, when on "Charge" I got from 80% to 83% in few minutes while I was testing.

But I'd really like to have hub that allows charging while using USB, because I plan to use it as a media player for TV (so USB HDD + charging would be necessary)

I'd be grateful for any ideas whatsoever to try out, anything that does not require opening and soldering devices :D
[Device Reviews and Information] Darth Ziggurat:
I had that hub and used it to install Windows 10, though it didn't work much after that, it partially then fully stopped functioning.
[Device Reviews and Information] mrkć_majstor:
I also bought Vi8 and for now I'm happy with it, except one thing bothers me. When I'm typing some text on tablet's touchscreen, almost never I don't get correct output if I tap two characters on on-screen keyboard at the same time. Sometimes there's no output at all and sometimes I get some other variation of character I probably pressed first (of the two I pressed). Is anyone also experiencing mentioned problem or this is the problem only I have?
[Device Reviews and Information] CosmicDan:
Windows or Android? On Windows 10 I can't say I've had the issue, I've used key combos fine.

[Device Reviews and Information] mrkć_majstor:
[MENTION=1844875]CosmicDan[/MENTION]: On both operating systems. The problem is appearing only when I type on touchscreen keyboard, with normal keyboard connected to USB OTG there is no such problem. Is there any software center from drivers, which may have settings to correct that? I believe that there is some setting which disables more taps at once.

EDIT: How long can you use tablet on battery with Windows 10 (if you compare to W8.1)?
[Device Reviews and Information] CosmicDan:
If its happening on both, that sounds like hardware issue. I have not had any issues with multitouch capability at all myself, but I am only using Windows 10 - could be a huge coincidental bug in both Win8 and Android, bit seems unlikely.

Try to find some app/software for testing multitouch. I don't know of any, so have a Google. That will at least rule out digitizer problems, if its OK.

I have no comparisons for battery life, I got rid of Win8 ASAP. But it's not great, battery life in this tablet is it's biggest flaw.

[Device Reviews and Information] CosmicDan:
Regarding deleting Recovery partion, I don't recommend it. There are actually two, the larger one you can delete but the other one is tiny and is WinRE - if you delete that and have unbootable system you will *need* an external USB Win10 disk to perform any repairs.

did windows update 8.1 with bing for windows 10 home, formatted to remove the Android and installed windows 10 home (downloaded from the Web) so that is not automatically activated (it says it will expire in three months "11/18/2015"

like the original iso vi8 Chuwi (only Windows 8.1 with bing) .to not lose the original license and upgrade to Windows 10

ps: There is an iso windows 10 home compatible with the license of vi8 Chuwi

I'm seriously considering this device for basic use. Not looking for super fancy. Have any of you experienced any issues with it out of the box? How is the performance of this device? It looks great on paper, fast cpu, 2Gb RAM, 32Gb eMMC.. The specs are amazing, just curious how the real world use is. I want to use it for an ereader, browser, email, etc... Thanks in advance...

just writing from vi8. for your usage it has enough performance. but be ready you can get tablet with dead pixels or dust under the glass. low quality speaker is not good too. but it is still fine device for that price and even battery is pretty good.

I could also not get root on the Vi8. Tried everything (Also CWM and SuperSu).

Found out that if you put the device in recovery mode, you can mount the file systems in R/W mode and remove the suspicious packages that way. For me this was enough.

I was able to obtain root using vroot or iroot. Once you have root google vroot super user removal, to replace the installed super user with supersu.

Could you pls do a root guide for me?
[Device Reviews and Information] krkspds:
Use Google. It works. Search for iRoot. It has instructions. Then search "replace vroot superuser with SuperSU". You will info in these forums as well as YouTube.
[Device Reviews and Information] mordydd91:
Iroot work fine... But some app don't recognize it

HDMI problem

Hi, i'm having issues getting the HDMI to work. It doesn't work on android and windows. I have tried many different cables and adapters and screens. Also i tried resetting windows. And even tried reinstalling the graphics driver. But i'm still getting no output and no screen detected in the settings. The website where i bought the tablet (banggood) doesn't respond to my emails. Any ideas?

Thanks in advance.
[Device Reviews and Information] LuxZg:
Chuwi has a "deep HDMI" issue so to say. On the cable's micro connector cut the rubber/plastic a bit, just a little, so it can go deeper into Chuwi's own HDMI port. It's weird issue, and McGyver style solution - but it works fine.

Thanks, I can't seem to be able to find instructions on how to enter recovery however, holding the vol up button send me to OS boot and holding vol down does nothing. Am I doing something wrong?

I've tried searching the thread for this and I can't seem to find it.

Update: Managed to get to recovery somehow based on the flash tools posted on first page. Sometimes it just puts me into CWM. I've managed to flash a supersu zip and the Kingoroot Superuser app is gone. Now I need to update my binaries and doing it through Super SU doesn't seem to work. I still never to figure out how to get into recovery.

Whats wrong with SuperUser ? Working well.

What is the difference between SuperUser i superSU ?
[Device Reviews and Information] mrracs:
I need to remove windows completely and make it an android tablet. Is it possible? and how? thanks
[Device Reviews and Information] BlueFlame:
CWM is (if I remember correctly) recovery mode. If you connect to the tablet using ADB Shell while in this mode, you can mount the filesystems in R/W mode and edit/delete. System is what you need to remove packages (SuperSU for example, but don't forget the malware packages that Chuwi puts on there by default).

After you removed these packages (and SuperSU) try the iRoot option a few posts above (I have not tested this, I gave up after I found out that I could do what I wanted in recovery mode)

SuperSU binary's cannot be updated because the device is not successfully rooted.

What commands do I need to type in to remove the Kingoroot and malware packages?

[Device Reviews and Information] ma_c:
How I can recover all partitions on the chuwi vi8?

[Edited]: Solved
[Device Reviews and Information] BlueFlame:
Get the devide in recovery mode, then with file explorer go to the directory where you installed adb. While holding the SHIFT key, right click on the platform-tools directory where adb is in and select "Open command prompt here" (or something, in dutch it is "Opdrachtvenster hier openen").

in the command prompt, type:

adb shell

mount system

cd system

cd app

You can now give the commando "ls" to view all packages in this directory.

delete the packages that you want to remove (command is "rm filename" while in the correct directory). I removed the following packages:

system/priv-app

XFota.noicon.9106.apk

XFota.noicon.9106.odex

system/app

FileManager.apk

FileManager.odex

OpenWnn.apk

OpenWnn.odex

VideoEditor.apk

VideoEditor.odex

GooglePinyin.apk

GooglePinyin.odex

system/preinstall (aka. chinese gift pack)

aiyude.apk

baidushoujiweis.apk

jiuyouyouxizhognxinHD.apk

MXvideoplayer.apk

shoujibaidu.apk

taobao.apk

tengxunshiping.apk

Please note that this is potentially dangerous if you don't know what you are doing! If you accidentally delete a complete directory out of the system directory, your tablet could no longer boot in android!

Please first read up about the commands described by me before you use them.
[Device Reviews and Information] hollowsmart:
Thank you!

OTG not working

Hello,

someone before me has upgraded from stock 8.1 to Win10 on this tablet. As a result, touchscreen is not working properly and OTG cable (USB mouse/keyboard) NOT working. Therefore i am unable to do anything to repair the damn thing (which is what i am supposed to do).

I can´t even go to bios (esc on boot NOT working).

Is there any solution to this strange problem?

[Device Reviews and Information] falihax:
In advanced settings during Windows 10 setup I chose Add Driver and selected the I2C driver.

After completing I just clicked on all of the devices with missing drivers in device manager and selected to add from local computer (including sub folders) and let it install them all. Without doing the add driver during setup it would not work correctly.

I used the drivers that were saved using the dd.exe tool, that you probably have if you have multiple driver packs, but did not use the tool to restore them, just used device manager to point at the folder.

Yes. I partitioned my 64 gb to use 10 gb for Android and the rest for windows. Though switching is not so smooth. Windows to Android is OK, but going back to Windows you need to shutdown first, then physically remove the micro SD card, put it back in, then boot to Windows. Otherwise, Windows cannot detect it.

As for updating, I did it manually (followed the instructions in the Windows website) and went without any problems.
