Did some research and this touchscreen issue is definitely related to the ungrounded charger supplied by the manufacturer.

Apparently it's a common problem with newer touchscreens because of the push for thinness. It produces EMI interference that causes a "ripple" effect to cross the screen outward from the charging plug. This is why the extra touches always seem to be in-line with your finger. A way to avoid it "temporarily" is to touch the grounded edge of the USB port or other exposed metal surface while using the touchscreen. It puts you on the same ground plane as the device and "mutes" the "ripple" effect.

The cleaner the power from the Mains the less you'll notice this effect. So a quality surge filter will probably help at the plug end.

You could also try one of these.. Which should filter the noise out and "mute" the "ripple."

I think I have one of those barrel filters at my house. I'll try to find it and see if it works for me. Touching the USB port works for sure as I've tried it myself.
[Windows 8 General] Buggster:
Magic gold rope, my basement visitor may appreciate that. Eew. Just kidding guy's! :)

What I have reckoned so far is that using 1.5a vs 2.0a charge would be beneficial to

lessen the interference when loading. So at this point I suspect using 'a' capacitor,

as already suggested, as the magic part. The extra benefit would be an longer cable!

It would slowdown the loading cycle, but don't see a problem there.

Anyone volunteering to make an schematic?

edit; good find thmagi. didn't see your post there.

Hi guys, I have a problem with the voyo a1 mini, my sister played with the bios setting and disabled the onboard video card. Can I reset the bios?

thanks
[Windows 8 General] xxLeoxx93:
No, I've the same Problem and the only way is to replace the bios chip.
[Windows 8 General] tobyax:
Ok, but the only thing that does not work is the screen, if a person keeps track of the steps to get to the BIOS where the video card is disabled, you may be able to reactivate ... No?
[Windows 8 General] ebsbow:
Did you try hanging it on a monitor yet?
[Windows 8 General] tobyax:
what do you mean?

one question. what is the difference between these two voyo?

this

[Windows 8 General] xxLeoxx93:
He disabled the graphic-chip, so no monitor will work.

Maybe someone can give detailed instructions how to reset and save the Bios blind.
[Windows 8 General] ebsbow:
Could be he/she only disabled the dsp. So external may work.
[Windows 8 General] ebsbow:
Assumption abased on circumstantial evidence ;)
[Windows 8 General] Downstar:
Mweahh i dont like that blue color..

if it was in a black/greyish color it was much better :P

Btw, guys..

I red that the voyo a1 mini ( and other devices like pipo w2 etc.) can charge by micro usb port.

I thought it should be work nice with my Xiaomi Powerbank (10400), but if i connect it, it isnt charging at al..

Even my normal power adapter for my smartphone (5v 2A) isnt getting the voyo chargerd..

Is this normal? i thought i could be chargerd by micro usb port?

Does anyone else has this problem? or do i need to activate something i windows/bios or something to get it work?
[Windows 8 General] nips:
Nope same problem here! .... i read too that the USB "trickle" charges the device but no luck here either!
[Windows 8 General] Downstar:
Well, i also see this feature advertised at other tablets like pipo w2 etc.

My friend owns a onda tablet, i will ask him if this feature work on his tablet..

Badly it doesnt work at the voyo, with a 10.400 mah powerbank you could have some great standby time :)
[Windows 8 General] Tonian1878:
dont know about other Onda Tablets but the v975w can only charge through micro USB.

wish it had a dedicated charge connection as well
[Windows 8 General] wlado93:
I wrote them and they wrote me this:

And in comments are wrote:

on more expansive: is info that it has Z3735D CPU

and that cheaper has in tittle: Z3735F

So this could by differences :)
[Windows 8 General] ebsbow:
You just need an adapter 2.xmm to usb female for that powerbank.

USB charge has been removed on the F version.

Is anybody using there tablet with an monitor, and what are your colours like?

From what I read, colours are exceptable but washed out in comparison to

normal HDMI out put. (I can confirm this)

---------- Post added at 06:27 PM ---------- Previous post was at 06:24 PM ----------

Banggood doesn't sell D anymore.
[Windows 8 General] wlado93:
And I ordered this tablet from buyincoins

I wrote before order message to support, which CPU is used. They can't correctly answer me a long time. They two times send me:

but another employee (Hana) wrote me this

So I hope it will be Z3735D :D I used 2% coupon, so price was about 121€ and I choosed original box. I ordered it 25th November. I'll write when it arrive :)

I want ask if someone tested this keyboard on Voyo A1 mini: http://www.buyincoins.com/item/44318.html#.VHiB7TGG_0w

It's for Ipad mini, but I read somewhere that it should fix for this tablet.

Tested someone 64GB/128GB microSDXC class10 memory card ?
[Windows 8 General] Downstar:
Hmm WHY :(! haha

well yeah, i think it should be faster with a 2mm to usb connection :)

But yeah sadly its removed :X

As far as i tested with my voyo tablet, the HDMI output on TV was just good.

Non washed out colors, my TV screen has better colors then the tablet itself was my conclusion..

I'm making some (video)review of the tablet, just a simple one to show people the features of an windows tablet.

It's in Dutch, but when i am finshed i can post it here aswell :)

---------- Post added at 07:02 PM ---------- Previous post was at 06:48 PM ----------

Why this keyboard wont work?

its just a bluetooth one, not any apple/ios only protocol or something

so i think it should work without any problem?
[Windows 8 General] wlado93:
I know that it's BT and it will works, but I don't know it tablet will fit into that space for ipad :)

And apple has dfferent ESC button, this button works like ESC ?
[Windows 8 General] ebsbow:
For some reason the tablet sees my monitor as an digital tv and there is an obvious

difference in colour reproduction. The video signal from my pc definitely has deeper blacks

an more vivid colours on the same 1080p monitor. Anyone else?
[Windows 8 General] wlado93:
Which HDMI connector has this tablet ? Mini ? Micro ? Or classic (like NTB/PC/TV) ?
[Windows 8 General] Downstar:
Mini
[Windows 8 General] ebsbow:
Indeed, a mini HDMI connector.
[Windows 8 General] Downstar:
http://www.ebay.com/itm/5Ft-1-5M-US..._USB_Cables_Hubs_Adapters&hash=item1c459b1c50

think i will buy that cable to connect to my powerbank, so i can use it to charge the voyo tab :)

this is the correct one right?
[Windows 8 General] ebsbow:
You'l need an 2.5mm connector.

Here you find some interesting experiments by a Korean hacker:

http://translate.google.de/translate?hl=en&sl=ko&u=http://mvapple.com/126

He observed the voyo a1 mini board is same as pipo w2 and he tries to flash the more recent bios of the pipo w2 to the voyo.

In another article he writes about the risks of setting quiet/fastboot mode in the voyo bios :

http://translate.google.de/translate?hl=en&sl=ko&u=http://mvapple.com/118

And in this article he describes how to recover from a bad bios flash:

[Windows 8 General] xxLeoxx93:
Thanks for these interesting links! I still look for a way to reset the bios after messing up some settings...
[Windows 8 General] wlado93:
I don't know how BIOS on tablet store settings, but if it's like PC/NTB you should try disconnect primary battery and press power button, or if you find second battery (like has PC/NTB for store BIOS settings) you should try remove that too...Maybe it will reset bios...
[Windows 8 General] xxLeoxx93:
Allready tried that, but without success. The Bios and it's settings is stored on "normal" flash-chips, so disconnecting the power doesn't have any effect.
[Windows 8 General] wlado93:
That's bad news. I definitely will don't do any changes in BIOS when tablet arrive to me :D

[Windows 8 General] oile:
When I bough it at the end of October it was very difficult to find a pipo w2 or a voyo a1 mini D version because they were discontinuing back then. I'm thinking of selling mine tough, so if anyone is interested in D in EU can contact me.

what you have? pipo or voyo?

and where you live country? nvm saw your profile italy, i live in france btw

im thinking about buying a cheap tablet to get stared. and when i have more money buy a 10.1" one.

---------- Post added at 08:49 PM ---------- Previous post was at 08:47 PM ----------

ow and there is no major differnce between. pipo w2 voyo a1 mini cube iwork8

cause voyo 114 euro gearbeast, cube 110 euro dealextreme, pipo w2 having found a site who sels it. but i mean they are like 100% the same so still voyo looks better

and i still can't see the differnce between the D and F series. realy

i know G and E are limited to 1gb ram. but why 2 different lettres for the same thing?

ow okay yeah like you guys sayed 15C° difference. but does that realy mather?

oww http://www.intel.de/content/dam/www...sheets/atom-z36xxx-z37xxx-datasheet-vol-1.pdf page 32. i dont understand sh it of it. but type 4 D and E seems faster higher numbers.

and can you charge the voyo via micro usb? or only the special charger?
[Windows 8 General] oile:
[MENTION=487710]jockyw2001[/MENTION] why skydiver? It is too much demanding. Ice storm unlimited on the same 3D mark version should give about 12000 points. That's the affordable test for integrated graphics. [MENTION=3259959]reggiexp[/MENTION] the voyo charges from 2.5mm plug, with a led indicator, separated from MICRO USB. Recharge from microusb on D version is possible although is a non-charge but almost a non - discharge (wich is good however when you have only the smartphone charger for example in your hands).

D version seems stronger in cpu power

okay thanks. so you thinking about selling? or didn't you mean that?

Im looking for a windows tablet with 2gb ram for like less than 100euro but all who are lesss than that are 1gb ram i cant live with that. But now afcors i want the D version. Faster is always better, specialy me who want to play some games

Btw cube iwork 8. Its for 110euro on dx.com

And they say its a 3735D. Dealextrem seems good.

Gearbest has voyo but the F one.
[Windows 8 General] reggiexp:
???

just saw on a site since 3dec they changed the cpu..

can any one give me a site for europe. where i can buy a 2gb ram z3735D tablet? for like 100-120 euro?
[Windows 8 General] paul89rulez:
F here, fast and with great battery life. D as i seen have touch problems , and bad battery managment.
[Windows 8 General] reggiexp:
Realy? ow yeah battery life is different what i have found is that the F version has a 5v charger. and the D a 9v charger acualy no idea if this changes alot.

Cause of gear best i can get the voyo a1 for 104euro.

Or pipo w2f 100euro but the pipo is different. Has no special charge port. (so you cant use usb otg and charge at the same time)

Ow and can you use hdd with otg i supose yes? And can you still charge a other device via the usb port? Like a phone? cuase the D can charge other things via it's micro usb. and since from what i understood the F version cant charge via micro usb (so im curious if that also changes that the port can't charge other devices.). The D could but slow charge it self via usb. So was curiois what els changed. cause if you can still charge a phone via the micro usb port with the F version than i don't mind that much.
[Windows 8 General] xxLeoxx93:
Is there a way to flash the bios within windows?
[Windows 8 General] Downstar:
Gearbest also have the coupon VOYOLG to get discount, so maybe you can het better price by that :)?
[Windows 8 General] reggiexp:
Did. The tablet is actually 112euro. But when i apply code it brings it back to 128 and pulls off 25euro so its 104euro. Not bad. Just curious how the import tax etc is. I've read onna dutch site some one who bought it he say he didnt have custom duty tax. But i want to be sure not that i have to pay like 40euro-60euro more. Than i can better get it from amazon for 165 euro

---------- Post added at 12:34 AM ---------- Previous post was at 12:33 AM ----------

Can any one plz answer my question about charging the tablet with the usb port. And charging a phone via the tablets usb port? With the F version?
[Windows 8 General] jockyw2001:
For importing a tablet pc, in most european countries the customs will charge you only VAT. I always ask the seller to clearly indicate that is a gift and value ("Gift. Tablet PC xxx US$"). In some cases I didn't even have to pay VAT.

The Voyo A1 mini with a F can not be charged via the micro usb plug.
[Windows 8 General] reggiexp:
Vat? That is How much?

And oaky yeah thats what i understood but you can still charge a phone or something els via the usb port? Like thr D version could?
[Windows 8 General] Buggster:
It is illegal not to pay VAT. You could be indited for tax evasion.

It's also

not allowed

to post or suggest this behaviour or

other illegal activities on XDA.

[Windows 8 General] jockyw2001:
Don't know in France just look for it on your french customs site.

[MENTION=2331334]Buggster[/MENTION]: nobody here is recommending evading taxes. It happens from time to time that customs don't charge VAT.

[MENTION=535343]all[/MENTION]: just contact your local customs office or check your national customs web site. In my country there is no import tax charged on a tablet pc, only value added tax on the total price incl. shipping

jockyw2001

Ow yeah i remeber is was from 150euro and higher you pay tax if im right. Was looking at it some time ago. Thanks any way. But just can any one answer my killing question? XD can you still charge something with the usb port. Like a phone? I know the tablet wont charge via usb port. But how about charging a other device with the usb port. (thats a nice feature the D version has charge it self via usb and can charge other device via usb but since yhe F cant charge it self via usb tought maybe that other feature is gone also.) its already 2days that im asking around still havent got a answer...

nvm its just with china post or air mail you have less chance to pay TVA 20%

every thing thats sent from out side europe u need to pay 20% of its price in tva at delivery. or something.
[Windows 8 General] jockyw2001:
Later today I will connect a few external 2,5" HDD drives and see if it works.
[Windows 8 General] reggiexp:
Thanks and try to charge your phone via the usb port also see if it works i supose you have the F version. Thankss. I know it all works on the D version.

Thanks in advance.

Thats the only thing i wanna know. If hdd and if you can charge a phone via the usb i will buy it. Than i dont care if its F and maybe slower.
[Windows 8 General] Dennis5:
Hello! I Received this tablet a few days ago with a chinese username and I don't know the password. Tried to contact the seller (from Aliexpress) but until now no answer! How can I perform a factory reset? Or where can I find its firmware/image? Thanks in advance.
[Windows 8 General] jockyw2001:
Charging my iphone 4s from the voyo micro usb works. Unfortunately my voyo's micro usb can't provide enough power for my WD Passport (320GB) and Intenso 1,5TB HDDs. When I connect the WD Passport the dingdong indicates the device is recognized, but then it immediately detaches, and so on. So it seems it can just not provide enough power. I also tried a 128GB microSD in a USB adapter and that worked fine.
[Windows 8 General] reggiexp:
okay thanks dude. you are my hero. realy no one could answer this question. if been looking to find a answer for 3days. i know all about hte D version. but thats old news now. you can only find F now.

ow so 2.5" hdd dont work that sucks. but your phone charges via the port. that kind of wierd. yeah usb sticks or adaptor works almost always.

yeah i tought so that there where differnces. cause the D version has more things. and i guess a better usb port power chip what ever you call it.

that why you can charge the D version via usb. and not the F one. its the chipset who is not as good as the D one.
[Windows 8 General] mirchichamu:
I am having the F version from another brand which charges via USB.
[Windows 8 General] reggiexp:
whats the brand name

yeah but has it a special plug for charging also? or is it only micro usb?

cause the pipo w2F looks like it only micro usb charging.

i mean voyo is nice so you cna charge and use the usb port at the same time
[Windows 8 General] sikica133:
using the port and standard OTG cable wont work, however if you're using an usb hub (it doesn't have to be externally powered, as you can see, mine isn't atm), it works. (3735D here)

I actually use this combo daily w my 250GB transdend drive and it's been working flawlessly. theese tablets imo, can do pretty much anything. been using one for 7months now and no problems whatsoever

oh yeah, and btw, this hub can actually charge the tablet if you plug it to wall charger, while allowing you to use 4USB ports. pretty cool imo, and there's no need to carry the original 9V one
[Windows 8 General] reggiexp:
thats the thing you have a D version.

the chipset have there differnces. the F version lacks some things. like i was thinking the F version doesnt provide as much power trought the usb port like the D version did. thats a reason why you cant charge it via usb. and i dont even think the F version can power a external hub with the power of the tablet.
[Windows 8 General] jockyw2001:
I prefer my F-type voyo since I can use it with my mobile phone for tethered mobile data, where the phone is charged by the voyo and the voyo is charged by my 5V/15000mah power bank. The same setup probably doesn't work with a D-type voyo which has a 9V charging plug.
[Windows 8 General] reggiexp:
ahh smart one. yeah that would work. but im happy to see that it can charge a phone. even if my oneplus one has a 3100 mah battery thats like 65% of the tablets battery still.

btw jocky you got i think my 5 thanks of the day. you realy helped me
[Windows 8 General] sikica133:
D doesn't charge drive either by default, at least mine doesnt. can F's be charged via standard USB port? if they can, they can charge the drive 99%, if you use a proper hub. can't be sure tho
[Windows 8 General] jockyw2001:
F-s can't be charged via the USB port.
[Windows 8 General] sikica133:
oh, bummer. well that's awful. explains why they are so cheap now
[Windows 8 General] reggiexp:
Yeah the F one is cheaper and not the same performance and has some features missing. Its acualy a downgrade the F model. Its kind of wierd from okay chip to a downgraded chip. But hey its cheaper ;)
[Windows 8 General] jockyw2001:
I really don't care at all because it has a 5V/2A charging plug which works great with any powerbank or any standard charger.

Could you please, if you have some spare time, run the same benchmark as described here? Anyone with a F or D please.
[Windows 8 General] sikica133:
true, then again, not being able to charge it via USB is just :eek: everything else, I can live with

will do tomorrow
[Windows 8 General] reggiexp:
Yeah but than again form 9v to 5v stock charger. So now you can buy a usb cable with 2.5" plug to charge it no need for its plug every time. But i was more curious about the usb on the tablet is its still able to give as much power as befor.

Now im sure im gonna buy it. I mean even if there we be import tax. Its still only 127euro total than. But if im lucky for once i can maybe save the 20euro extra and buy a bluetooth keyboard and mouse.

Btw any one know if you can use more bluetooth things at same time. Like a bluetooth keyboard and a bluetooth mouse. I know phones can send music via bluetooth and use a other thing at the same time. (don't want to use the usb port for a keyboard or mouse) saw a mouse for 10euro or 20euro and with bluetooth and maybe a keybaord cover case around 20euro also would be cool
[Windows 8 General] sikica133:
well, it's definitely a great buy for that price.

also, I'm not using voyo's charger, rather my G2's stock one @ 5V 1.8A so no probs there
[Windows 8 General] jockyw2001:
I think you can connect up to 8 devices via bluetooth. I just connected my iPhone 4s and an iMac. Connecting a BT mouse and keyboard and a mobile phone should be no problem.
