Touch issues when fully charged and pluged

[Tiago Conceição]

Hello again

I have recieved today the replacement, i test it again and still same problem… Touch issues when charging.

This time i have buy a good USB-C Charger and use it directly on tablet and problems gone, no more touch issues. From now i will use alywas the USB-C Charger. They should build cube i7 and future tablets with usb-c charger in box instead of crappy power supply

Since you have the same problem with the replacement I would think it’s probably something to do with your electricity supply or house wiring. Seems like quite a rare problem, I’ve never experienced it with the stock charger. Good you got a workable solution with USB-C.

I doubt about that but i will try on other houses too. If is a housing AC problem should type c have same problem? both chargers are not grounded.

But yes they should drop that DC jack and provice already a good type charger

Now i got other problem (i think and i still testing) when i get this tablet it have 0% charge, it took a while before i can turn it on. As i know lithium can’t be discharged to low levels or damage may occur. And i think is the case… I charge to full 100% then i disconnect and windows report 50% battery only, automaticly drop 50% after remove the jack, and windows battery report show same result from 40.000mW to 20.000mW. I fear i get even a worst tablet because this one may have a battery that is already damaged. At least other table come with more than 50% charge at first use 🙁

I will try another cycle to test

I’m sure your unity is faulty, mine doesn’t have any of those problems. Even the touch works perfectly when plugged.

It’s the secound time in row i send a china table to warranty for a replacement and i get a worse unit 🙁

[Katagiri]

Oh, Lord! Where did you buy it?

[Tiago Conceição]

Chuwi from Gearbest with same touch problems, returned and get a worse unit with serious problems

Cube i7 book from Banggood, touch problems, and now they sent me a unit discharged over a month or more

Battery report says 11% wear, 2 cycles with me

And the fun fact was in both times a fear that could happen (get a even worst replacement

Note: First Chuwi i get from gearbest havent touch issues when charging, but scren cracked, my luck i guess

Oh, my… I bought my Cube i7 from AliExpress, no issues so far, only Windows issues but those I could fix by myself.

[Tiago Conceição]

I only buy from gearbest and Banggood because no EU Tax, otherwise aliexpress all the way too.

And i can say Banggood have the best service for return, because they instant refund postage fee and send replacement before recieve the faulty unit, after i have sent the photos of package and receipt they sent another replacement. Gearbest is trying to scam me, 1 month after they recieve my tablet and still they say not recieved, full tracking and they still saying not recieve and have to wait…

Also i will not send this back, if battery goes worse i will build a pack my self and replace it using the pcb and wire from the original.

I already have done the heatshink mod, getting 20-28ºC idle and max 70ºc burn test

No matter where we buy here we have high taxes. I friend of mine bought a phone and received it with no taxes and he was bragging about it on Facebook. How lucky!

What is your country?

Now i have plugged a usb c hub to test it (HDMI/USB3.0/USB-C/RJ45) and it works. After disconenct i see sparks from tablet USB-C connector and screen do some horizontal blank lines and disconnect the keyboard xD This tablets have a very high quality 😀

New update: Tried a good stabilized 12V transformer and works without touch issue!

I’m from Brazil, the tax hungry Country.

I’m glad you are managing to solve your issues.
