I have only had it for a couple of weeks, but I am very pleased with my hi12. I don't notice any sensitivity problems. I have seen many suggestions to remove the screen protector - I just removed the outer layer that was left on over the screen protector, but not the projector itself. I also installed the SwiftKey keyboard, so I'm not using stock.

sumdog are going to work on a fix fingers crossed should be sorted in a week.

next problem is the screen sensitivity:

Hello,

I've just got this tablet and already run into an issue with the audio apparently :D

With Windows 10, every time i press a key on the virtual keyboard, or even when speaking in the mic to cortana, I can hear a cracking/clocking noise from the speakers. Could it be some kind of interference? Maybe some driver issue?

That'd be a pity since the tablet is performing very well otherwise.
[Device Reviews and Information] Frank-HRO:
The same problem here. In android all is okay with the both speakers. In Win10 cracking noise on the right speaker.

Left speaker is okay. Is this a driver problem?

I had the same problem

White noise only in Windows all the time. Just Uninstall both the audio peripherals and install them again...

Hi,

can you post your Sound card(s) driver version/date and hardware ID please? (I'll post mine later, since I'm at work currently)

Just so we can see what is the difference between tablets with/without crackling.

Because my has absolutely 0 problems with sound on speakers, headphones, bluetooth... I even installed Equalizer APO (you need to disable sound hardware acceleration to 'enable' equalizer), to make the tablet louder in Windows, and sound is perfect.
[Device Reviews and Information] Frank-HRO:
After Installation of the new Windows Update 1607 all is okay. Sound works super. Thank you for your help.

Good day everyone,

I am planning on purchasing a chuwi tablet dual os...

I have a few questions...

I wanted the hi10 because of portability but read that it only has 2MP back camera, yet when I look at some sites, it states it has a 5 MP back camera... which is true?

Another option is to go for the hi12 for a bigger battery... now I had been reading alot that you are not to update your hi12 using the windows update for it may brick your device, how true is this?

Which of the two, hi10 and hi12, has less headaches with regards to updates? The only difference from what I read is the screen size, battery, resolution, but they are identical in available ports... is this correct?

...
[Device Reviews and Information] alesi80:
hi. the wrong automatic updates that bricks the tablet is now safe since almost a month... it was a single and isolated problem now gone.

I can't be sure about the hi10 but I have a hi12 and I would buy it again...

what would you use a a camera for in a tablet that weight almost one kilogram?

SD disappeared!

I have two microSD cards (128 and 64GB), same problem with both of them:

1) At the beginning it worked! Win10 was able to see the card, I was able to install apps and dropbox on it. Speed was OK.

2) Then the card disappeared (after few days of working). Not only the drive letter, it wasn't visible even in the DiskManager. And no driver problems were noticeable in DeviceManager.

3) After the week the card appeared again! And it worked well.

4) But after few days it disappeared again and remains invisible.

So the driver is able to work, bud mostly doesn't. STRANGE!

The card is visible when I boot to Android and ofcourse is visible in other devices (pc card reader).

So it doesn't seem that Chuwi is not able to make a working driver or fast enough driver. It seems there is some problem which under certain circumstances blocks the SD reader.

Is it really that big problem to solve it?

Any idea how to make it work again?

I do! and I would buy it again... consider that with the price of a surface pro you could get two or more hi12 and won't have a keyboard dock that good... sure you need to fix some little issues but it is funny too if you can do that!!!

I am really tempted... maybe in a few more months they would release new units that are already worry free... or maybe one with 3G capabilities... that would be nice.

I justo wanted to say that I have this tablet since yesterday and love it so far. I won it in a contest, never had a tablet or a notebook (I have a powerful pc and smartphone), thought and I'm tech savvy. I'm debating if I should buy the keyboard, the metal new one. Anyone got it? Any tips? For instance, how can I disable intel powersaving mode the YouTube reviewers talk about so I can have maximum performance?

Edit: I found out its in the graphics properties and it's nice to boost the brightness of the screen when we're outside.

I just ordered a glass screen protector from eBay for 9 bucks. It's essential, imo.

I'd like to factory reset both Windows and Android system.

But I'm not sure if doing it in the regular way is ok, since it's a dual boot device.

Anyone did it yet?

Working fine?

Great! I'm eager to hear how did you fixed the problem with 128GB sdxc card!

The anniversary update turned my tablet into a snail, it's super sluggish and freezes. I deleted the old version of windows to save some space, is there a solution or will Microsoft launch an update that fixes this issue?
[Device Reviews and Information] JirkaToksa:
Well still not bad! In my case the anniversary update killed my windows totally (infinite cycle of boot-restarts)!

I had to reinstall it (fortunatelly the Android partition remained intact).

There is a guide in this thread (I guess at page 4):

http://forum.chuwi.com/thread-2019-8-1.html

It describes how to install a clean Win10 system - aready with the Anniversary update and all Chuwi drivers (image prepared by apt forum member).

After flashing this image the system is stable, clean, fast - and there is 34GB of free space, which is very good value for dualboot version.

Ofcourse you need to backup your data, the system will be clean and you'd have to install all the apps again.

---------- Post added at 09:36 PM ---------- Previous post was at 09:22 PM ----------

There are lot of topics about this problem but no real solution :(

I've found just one workaround, not the real solution - one user suggested installation of old (Win8.1?) SD drivers, but it has significant disadvantages:

1) Card reads and writes are super slow then (max 10MB/s)

2) It only works temporarily asi the driver will be automatically updated sooner or later

So it definitelly isn't a reliable and stable solution especially when I need to use the SD card regularly and intensively - as an extension of built-in eMMC storage - I mean for installing apps, for hosting the Dropbox storage, atd...

I wouldn't bother so much if it just wouldnt work at all. But the SD card worked aproximately one week! I did install apps and Dropbox storage there. It worked well, it was stable and fast enough.

But then suddenly the card disappeared. Not just the drive letter - it isn't visible even in Disk manager. But in Device manager it looks like the driver is correct with no errors displayed.

So that's why am a bit angry - because it aparently CAN WORK, because it DID.

And ofcourse I can see the card when booted into Android the whole time.

Many other people had the SD problem from the beggining, I started to have troubles after a week spent without problems.

It's just very strange.

Why isn't Chuwi or some skillful forum member able to fix it? Could it be that big problem if it was able to work the first week?
[Device Reviews and Information] Badelhas:
So you don't believe that a future update from Microsoft will fix this? I explain you what's happened to me: I received the tablet days ago (I won it in a internet giveaway) and the first moment I turned it on I proceeded to doing the update (I had already do it in my home pc a week ago and everything went fine - even though it's a very powerful pc). I don't have anything to backup since it's completely new and unused. I had little time to try it before the update but even though the specs are very low end (processor and storage particularly) it definitely didn't feel this much sluggish. Does yours feel slow and freezes just by using Edge or chrome?

Regarding your issues there is a moderator the Chuwi forums if you need help from someone a tech representative. I asked a couple of questions there but haven't received a response yet but there's a moderator (Moto-something) which appears to work for chuwi, maybe you can ask him directly.

Cheers
[Device Reviews and Information] k818mn1:
I did the windows 10 anniversary update last week with no problems. The update certainly didn't make it sluggish. Since you deleted the old version of windows your only option is a clean install, which isn't too difficult.
[Device Reviews and Information] Badelhas:
Thanks, I did it last night and the smoothness seemed much better but then I did better two cumulative updates to 1607 windows anniversary that were available that seem to broken Edge Browser again since it's freezing again (webpage stopped working) and UI is a bit slower as well, but I don't know if it's my impression or not.

Should I just uninstall them or will windows install them again automatically?

[Device Reviews and Information] TMSxXDA:
Can anybody express his opinion on stylus writing quality? there is very few unclear reviews on YouTube that says it is problematic, in sense it is not vey accurate at edges as Wacom or N-Tiger of Surface, and some times there is gaps in writing, and sometimes needs to be pushed hard.

I will need it to write complicated formulas, so I need it to be pretty accurate to write small letters\numbers without zooming in and out, If you can compare it to Cube Stylus i7 experience will be thankful.

Also please indicate your tablet production date, as it seems there is differences.. thx
[Device Reviews and Information] pr0xZen:
Plenty of youtube reviews on it already, just google it. It seems fairly ok, and a very welcome addition to a tablet not only this large, but also given its high display resolution. Just note that the correct stylus for Hi12 is Hipen H1. It uses an AAAA battery. Some shops claim it is battery free, this is NOT correct. Quite uncommon battery (compared to AAA), so might want to pick up a couple of extras and have on hand, rather than find out once the included one is dead that none of your local stores carry it. It'll work fine with whats available, if you're one of the unlucky ones that got a Hi12 with "less than ideal" touch response, and the driver updates didn't fix that - neither will a stylus. Given that there never was a "Stylus" edition as indicated earlier, but all dualboot Hi12 units should support the stylus. Afaik, the only hardware change with the dualboot is the digitizer - if this is correct, it is possible to change the digitizer and flash dualboot bios firmware with an eeprom programmer directly. Don't really feel thats a financially sensible mod though.

If you need WACOM precision, you need to pay the premium required to get a tablet with a (well integrated) WACOM digitizer. Preferrably a fully laminated one to eliminate the gap, if you're looking for an optimal writing/drawing experience. While this tablet is a fairly good deal for the price, its still a relatively cheap unit. Don't expect premium features at a budget price, and you'll be less disappointed.

TL;DR

The Cube i7 is a WACOM unit, the Hi12 is not. So no, it won't be near WACOM precision. If you need WACOM precision, you'll have to pony up and pay the WACOM price.
[Device Reviews and Information] luca.costantino:
do you know if it possible to replace (expand...) the eMMC to 128/256 GB?
[Device Reviews and Information] Badelhas:
I don't think so. But you can insert a 128GB micro sd card. Just don't know what's the fastest speed supported. Anyone knows that?

Cheers
[Device Reviews and Information] luca.costantino:
Thanks.

Last question.

Is there already a guide out there to completely wipe the device and reinstall windows and android from scratch to readjust the table partitions and get rid of unwanted programs?
[Device Reviews and Information] Badelhas:
There's no unwanted programs besides the normal ones. What do you want to get rid of? There's no Spyware or bloatware, it's been checked.

There's a guide for a complete reinstall on Chuwi forums. You need to follow their tutorial otherwise it gets bricked because of the lack of proper drivers.
[Device Reviews and Information] luca.costantino:
OK, I just assumed it was full of the usual bloatware/crapware/spyware...

[Device Reviews and Information] anunknwon:
My tablet not arrive yet but as I know its trouble with your root device by supersu version. try to wipe and flash again with correct supersu version (this tablet using android 5.1 you can't use supersu beta 6 or late 5.1) (someone also said do not update supersu app. turn off auto update in play store)

Hi guys i just sell my nexus 10 and im thinking in buy this tablet how is android on this tablet do you think that will be custom roms available? do you recommend the tablet to android?
[Device Reviews and Information] Badelhas:
The tablet is a bit slugish in android, touch responsiveness is not the best, I tried it a couple of times and never opened again since Android is not particularly optimized for such a big screen, windows 10 in tablet mode is much better, in my opinion. I did the touchscreen mod (check the Chuwi forums) and bought the metal keyboard/dock and now have a notebook as well ;)

I'm surprised to see people complaining about Android on this device, as I find it particularly good. Sure, I'd like a newer version but even at 5.1 it's running really smooth and is responsive as hell!

Using Caustic to make tunes on a 12" tablet is so much fun. I'd really like to see some shared drive space so I could use Caustic (Android) and Acid and Fruity Loops (Windows) all together, but meh. I can live with using Drive.

I'm loving this tablet.

I am sorry, but my guess is not your real problem. let's analize better your situation

1) does it happen evey time you are on 50%?

2) does it happen on android as well as windows?

3) have you tried to completely discharge it and recharge for at least on night?

4) have you tried to let a movie go when battery is about 60%, to see if it happens suddenly or only when it is in sleep or deep sleep mode?

I've test the battery to be sure it was more than 3.5v, necessary to boot and necessary for the BIOS to charge.

unfortunately, my tablet did not boot again.

So after reading on chuwi'forum discussion, i've realised i've bricked the BIOS.

So i've bought accessories and i will see this weekend if i can save this tablet.
