Hi,
[Device: Lenovo ZUK Z2 Plus, PixysOS v2.4, Android 9.0]
My device stopped charging with my original charger, and also with PC, after I charged it once with Oneplus dash charger (due to unavailability of my charger at that time).
When I tried it again with Oneplus dash charger, it charges really slow (but it charges at least).
I have PixysOS custom rom. After I found that sometimes kernels also do contribute to charging problems, I flashed it with Nameless kernel [4.4.178, R29]. But, the charging issue still remains.
Any work around?
Solved the issue
Just had to buy a new One plus dash charger. Fast charging works.

Hi
I have owned an lg g4 T-Mobile for a few months now and it's on stock marshmallow and it's been working fine up till recently.
Here is the issue
1) phone sometimes doesn't recognise the charger, I tried different cables and chargers with the same result, although the problem was more consistent with a quick charger 2.0.
2) phone sometimes recognises the charger but I leave it plugged for an hour and the phone doesn't charge at all.
3) I used to charge my phone using a quick charger 2.0
4) no change in battery life
5) everything else is fully functional.
6) I stopped using the quick charger since and the phone has mostly been charging normally, I don't know how to explain it but after stopping charging with the quick charger, other chargers started charging normally again.
I can use the regular charger with no problems but I really miss the fantstic quick charging.
Could the quick charger have actually damaged the phone, is it safe to use it ?
I was about to buy this phone, but then i saw this: https://youtu.be/l-MmWqNrCH4?t=195
Can anyone confirm there are touch screen issues when the AC charger is connected?
This seems to be pretty big hardware issue and i wonder if it does affect all Zuk Z2's...
Can anyone test this please?

Depends on the charger and socket output.
Like when I'm using it with qc3 charger plugged into 220v output socket, there is no such issue, but when plugged into 110v (tried on train's socket), you can see that problem.
This problem is basically with every phone.
Indian Lenovo Z2 Plus here on Stock Nougat
No issues here (stock charger on 220V AC)
Oh well, maybe i have to reconsider it then
Anybody using the device had this issue(Ghost touch)?

This is common for all Zuk Z2 devices.
Its a issue with the charger & not with the device as such. Try using any other good quality charger, this will not happen or if you want to be sure try charging with powerbank you won't face the ghost touch.
try different socket in different location. sometimes ground wire has problem in home which leads to this problem.
I recently bought the phone, and yes, I have experienced the issue quite a few times. But, only a few times. Most of the time, device touchpad works normally while charging. I think thr problem is with the old sockets. I use Stock provided charger. I have heard that it's common in many phones, so I'm ready to ignore it. Because anyways phone should not be used while charging.
With reference to my previous message, I noticed now that the device shows ghost touches while charging, only when device is charging at max speed and is quite hot. While charging, when the phone was between 50%-80%, it had become quite hot (Not too much though), and it gave me ghost touches quite a few times. I think device charges at it's max during these percentage. But when the phone crossed 85%, the device started getting a bit cooler, and I didn't experience the ghost touches at all.
Issue solved
Hi buddy I had the same issue .one day while I connect my z2 with laptop I see that its charging but no touch issue then I realised it need low power charger than that given charger .After that I use my tablet's 5v 1amp .It works nice and it take 2 and half hrs to fully charge .After that I did not face any touch issue.Thats why they does not provide fast charger.I brought my z2 6/08/2017 from flipkart

This is not a phone issue. Lenovo is selling **** quality chargers and cables. If you happen to know (https://www.amazon.com/gp/profile/amzn1.account.AFLICGQRF6BRJGH2RRD4VGMB47ZA) this guy then see his recommendations and buy a good charger or you might even fry your device. This is very dangerous. Shame on Lenovo.

I'm using motorola original fast charger of cellphone of my wife.
I'm also facing this problem. I have divorced parents, the charger that came in the box was a US adapter that I couldn't use. My brother used to have a ZUK z1 and I use his stock charger Together with the original Z2 charger. That one works well. I bought a Blitzwolf USB type C cable, a Tiegem QC3.0 cable and a wish.com charger with great reviews supporting Qualcomm QC3.0, but I recently discovered that zuk z2 uses a different type of fast charging. On the blitzwolf and Tiegem cable i have ghost touches and the phone gets very laggy, does anyone have recommendations? thanks in advance
How will an iPhone charger work.
My proposed solution
I bought this mobile few days back and since then I also have realised about this issue. This isn't ghost touch but the touchscreen becomes ultra reactive with higher input.
I used several apps and found another thing that if any charger inputs anything more than 1.4 amps, the mobile's screen becomes ultra reactive. But if the charger inputs upto 1.3 amps, it is ok. I keep using a charger that gives max output of upto 1.3 amps and I can even play games easily without any issue.
To measure the amps, I use app from play store which is free called Ampere. I am nowhere related to this app, you are most welcome to try this method out.

Hello Everyone,
I am looking for a dash charger for z2plus , I just used my friends OP5 dash charger for z2 plus it works like a champ. But OP5 dash charger is expensive like 2k, any other suggestions on chargers ??
Thanks in Advacne !
I would say.. don't go for anything except original charger.. it can fry some important diodes on your board and I am not kidding happened to me twice...
First time, battery was empty, and phone never woke up, I had just installed custom rom maybe because of that...
Second, exchanged phone, new phone, stock everything.. and it happened again..
Then I realized it was because of the 3t charger...
Read few posts, and found out if used some qc 3 chargers it can fry the diodes cx68 something..
Better read those post before investing money...
Nonsense! QC tech and Dash Charge tech are totally different. If used, any oneplus dash charger will charge your Z2+ like a normal charger and not any faster. Dash Charge Tech is Oneplus's Proprietary and won't work on any other company phones. And Regard to Best QC3 Chargers, Only and Only buy & use Qualcomm approved QC chargers. They are tested by Qualcomm and will almost never cause any issues. The List of approved chargers can be found on Qualcomm's website.
After buying the Qualcomm Fast charger can this device charge quickly ???

The Zuk Z2 plus cannot quick charge (No QC2/QC3), atleast yet. Some say the hardware isn't present in the device but i believe with the other group that say it's locked in kernel. In the Fans page, a dev has posted a mod to enable QC 9V charging on kernel level. If you or anyone has QC charger feel free to try it (UNDER YOUR OWN RISKS). At Stock Charging Capabilities, the device can charge with 5.25V 2.5A max. You don't need QC chargers for this, the lenovo charger that comes in box is more than enough.
zukfans.eu/ community/ threads/ request-quick-charge-support-qc-3-0.2526/
1.5A on screen en 2.5A off screen all by 5V are the best charge number the z2 plus can do, so it does charge good but it's doesn't benefit from a dash or quickcharger like one plus phones do.
Quickcharging is charging at higher voltages for the same or sometimes even more amps. and since A*V= Watts you put more and faster the power in your battery
on sm-n9005 aka Smasung note 3 Lineage 14.1 latest nightly (dec 13) reports charging slowly
However it turns out it isnt.
If i can trust "ampere" app at least a little here is what i found with different chargers:
800ma - charging
900 ma - charging slowly
500 ma -charging slowly
1200 ma - charging slowly
1800 ma - charging slowly
anyone else have similar on their devices?
maybe its my old possibly dead battery or is it a bug ?
btw testes with follow chargers:
samsung original
nexus (htc)
samsung (very old)
LG
noname (chinesium)
On my OnePlus One running CyanogenOS (Marshmallow) it displays "charging quickly" when plugged into an appropriate charger.
On my LG G4 (h811) running LOS 14.1 (Nougat), it never ever displays "charging quickly" despite the fact that the G4 supports Qualcomm QuickCharge (the OPO does not) even when using certified QuickCharge chargers.
So I have assumed for a while now that this is an LOS issue of some kind. (When I used to use the original LG-provided Android build on the G4, the "charging quickly" notification worked fine)
Hi all.
i bought a lenovo K8 note and also it was working perfectly and now i have a problem in charging.
its already providing a turbo charger with this device. since before two day i connect OTG on my phone and after that when i connect charger all are showing charging over USB and its deadly slow to charge my device. it takes almost 9 to 12 hour for 0% to 100%,
i tried changed cable with new 2.4A fast cable. try with USB 3.0 Ports, Try With Wall mount Chargers 2.0 AMPS, 3.5Amps etc.
I reset the device and also i am flashed my rom with 7.1.1 (Stock ROM). nothing was helpful. still now my device showing Charging over USB while charge with any charger on battery screen. deadly slow to charge up device (almost 12 hour need to full the battery before it was 3 hour maximum time)
So anybody have the same issue. I hope our teams got a solution for this
let me know the solution please.

I am having the same issue
I was try to change the all are like charger, cable, etc. But nothing was helpful. Basically i am a electronics tech. So I just bypass the charging Lines directly to battery with a suport of and diode.
After that it was much better (but can't see the percentage while charging)
Now I sell the product to some shop..
Now happy with asus zenphone max pro m1
In my finding i got a Final report.
It's battery response issue..
The battery have turbo identifier inside. T+ t- mark ups. (I removed back cover and checked all)
You can see the turbo controller in battery.
Maybe if you are in warranty quickly visit services center and ask for battery replacement.
Have a good time ahead.
Admins This thread is now resolved my self. So please close this with my solution.
Thanks.
With love
