[Moto G4 Plus Questions & Answers] Septfox:
I don't have a G4 (yet, considering getting a Plus), but I might be able to take a little mystery out of this, at least for those connected to a charger...

Ghost touches are generally caused by chargers or USB ports with out-of-spec voltage ripple. Most standard phone chargers put out up to 150mv of ripple; if the one that Lenovorola supplies has poor regulation on its output, or the phone has poor/no filtering on the USB port and/or has an especially sensitive digitizer, this sort of thing will happen.

If the charger is poorly designed, the issue will be worse when charging from a low battery because the charging circuit in the phone will pull as much current as it can from the charger, stressing the charger's components (and possibly operating them out of spec if it's under-engineered enough). As the battery gets closer to full, the problems might let off a bit because the phone's charging circuit tapers the current down to cater to how li-ion/li-pol chemistries work.

The best solution, assuming the above is right, is to use a charger you know is strong and has good regulation. Alternatively, charge your phone using the passthrough of a quality powerbank (hook it up to the output port and your charger into the input); Xiaomi makes some good cheap ones that output stably. Powerbanks don't really care how much ripple goes into them as long as it's not enough to overly stress or outright destroy their conversion circuitry.

As for you guys who have the issue while on battery: dunno : \

Lenovorola might be able to decrease the sensitivity of the screen via software if that's the problem, but I kind of doubt it...the digitizer is driven by its own IC, and its parameters probably aren't accessible by the rest of the system.

Same problem here. But I saw this only a month after I got my phone.

Did you get a replacement?
[Moto G4 Plus Questions & Answers] krsambhav:
You Can't Fix It Bcoz The Turbo Charging Creates An Extreme Pressure On The Device And The Device Lowers Its Performance To Combat Heating Issues As Much As It Can And Thus Generates The Ghost Touch Issue And The Lag Issue Is Caused Due To The Low Frequency Or Lower Number Lf Cores online That Time.
[Moto G4 Plus Questions & Answers] cerberusss:
I agree, it's related to the turbo charging, after I charge my device it becomes complety useless , now I use a low output charger, btw, it only redused the frequency of ghost touches. I'm pretty sure it's a ground issue.
[Moto G4 Plus Questions & Answers] saurav_k:
Yes, I was reading that thread on Lenovo forum and they are saying this can be fixed by service center. What makes me wonder is that they have been suggestging this ever since the phone is launched and even in the new lots, people are facing the same issue. Why can't they ensure this is fixed at the origin itself? I haven't bought this phone yet but planning to but hesitant due to this. Very irresponsible from Lenovo.

Hi,

Not much sense to post here now..not even sending them email about our problems.

I've tried everything, but there is no response from customer care support.

Looks like they don't care about the customers..they just want to make money.

Please spread bad reviews for Moto everywhere, thats only the way how we can deal with it now.

Did you visit a service center as the recommended solution? Others have stated that this fixed their problem.

[MENTION=995598]alphadog[/MENTION] - I have some specific comments and questions on this. I have been planning to buy this phone being a loyal Moto user since Motorola Defy.

But, I can see clearly that this is a very common issue which many buyers are facing and even after months Motorola is asking to visit service center.

Now, do you think a prospective buyer knowing this will feel confident buying this?

If service center can fix the issue, why is Motorola not ensuring that this issue is fixed at the origin in subsequent lots. I can see it has been almost 4-5 months since the issue is being reported and still new buyers are facing this issue !!

This is shocking and extremely irresponsible from Motorola.

I at least won't feel confirtable handing over my new phone to Service center as I want to keep it neat and scratchless.

I am really shocked that even after so many complains Motorola has not done anything to fix this at the core.

Been a loyal Moto user but this time, saying good bye and exploring other options. Guess the Lenovo effect has taken over.

Also, extremely annoyed by the fact that Motorola has decided not to give Android N update to 3rd Gen and Moto G Turbo. Moto G Turbo hardly released a year ago. Bye bye Motorola. (after 7 years of continuous loyalty)

My battery is charging very slowly with trubo charger ?
[Moto G4 Plus Questions & Answers] Sunderesh:
Hmm try changing the socket (voltage fluctuations) if that doesnt worl may b u should get ur charger checked up btw... this is probably the first time i've heard slow charge problem while using a turbo charger usually its fast charging(compliment) or battery drain(sometimes this happens)....
[Moto G4 Plus Questions & Answers] Prasoon_Gupta:
Use a Different Charger

First of all, that's not a serious issue that may happen with any of the devices with touch display. I will not go in deep working of screens but the work with the potential difference generated by our touch or sticks/stylus.

The Turbo-Power brick which is bundled in the box is the culprit, (Only for those users who are facing ghost touch while charging.)

Hereby I will like to say that "You may try using a normal charger and that check if the problem persists."

P.S.- Those users who don't have ghost touch problem while using Turbo-Power brick they will experience the same after 8-10 months. So Prevention is always Better than cure..

And I think, That bundled brick is just for emergency usage. As you described that you have chose a different charger, I would recommend that you may go for Samsung/Micosoft micro-USB pinned charger, they are Non-Fast Chargers..
[Moto G4 Plus Questions & Answers] joa8000:
that happens because the phone is overheated. i read that on the motorola web page.

Keep the temperatures below 45°C
[Moto G4 Plus Questions & Answers] tech virus:
hey hey hey fellas....atlast found something which satisfies everyone regarding ghost touch....the latest qualcomm has made severe changes inside turbo powered charger which couldn't able to stabilize the input voltage fluctuations. and that is why we all expirence ghost touch... i even checked my socket with Multimeter...hell yeah that was true....

atlast ive plugged stock moto turbo charger to the stabilizer, believe it or not i played nova 3 for exactly 44 mins beside charge was on !

so this caused ghost touch !

hope you guys understood :)
[Moto G4 Plus Questions & Answers] aulurion:
I experience the ghost touch phenomenon on my moto g4 while charging.

At least in my case it seems to be related to the buildup of static electricity on the screen.

I could completely eliminate the problem by sneaking a very thin strip of aluminium foil under the protective case in such a way that while charging it touches both the screen and the insulation of the charging cable.

Of course this is not a permanent solution but fine for me until I am in a situation to send in the phone under warranty.
[Moto G4 Plus Questions & Answers] tech virus:
never keep aluminum underneath active battery especially while charging ! that causes improper flow of charge which reduces battery life gradually....and that is why even in wireless charging pads no aluminum cud be found !
[Moto G4 Plus Questions & Answers] aulurion:
I said nothing about the battery. Top of the screen to insulation of charging cable.
[Moto G4 Plus Questions & Answers] aulurion:
Unfortunately I was a bit too impetuous. I have to revoke my statement since I experience the problem again in spite of the measures described above. :(

SOLUTION?

Some people are saying that if you enable DEVELOPER Options in Configurations and Disable Hardware Overlay, it works and the ghost touches cease to exist. Could anyone try and confirm? I donÂ´t have this problem. I have a moto G4 (not the plus).
[Moto G4 Plus Questions & Answers] daverobinson88:
From my discussions with moto it stems from going from the turbo charger to a basic charger. It messes up the battery I had to get it replaced. They suggested I do not use the turbo charger. Low and behold using the other chargers I have around have not had any issues with the ghost touch problem. Also my battery life has increased dramatically after the replacement.

snapdragon soc of moto g4 plus supports qualcomm quic charge 3.0 and it no way kills ur battery, coz its officially supported by quallcomm snap....u can use regular charger bt ur charging rate wud be slow...
[Moto G4 Plus Questions & Answers] daverobinson88:
I am going to play devil's advocate here and say just because a chip or software is supported by a manufacture doesn't mean the OEM recommends it. Perfect example. Just because windows 8 was supported by Microsoft didn't mean OEMs recommend it, heck they gave free rollbacks from it.

I tested charging and from nearly dead takes little over 1 hour to charge with turbo charger almost 3 hours on my moto G3 charger. When your sleeping it doesn't really matter lol. When I'm told not to use it by moto and why they had to replace my battery is my evidence. I see the change from not using the turbo charger on longer battery life and no ghost touches since.
[Moto G4 Plus Questions & Answers] derausgewanderte:
My son's Moto G4 started acting up with ghost touches after 3 months. He only ever used the turbo charger the phone came with. RMA'ed the phone and got it back working fine. If it's indeed a change between charger that causes the ghost touch then they'd have a recall on their hands. PS. I've been using my Moto G4 Plus with varying chargers for a few months with no issues at all.

That's my limited evidence that it has nothing to do with the charger, but rather with a small batch of poorly manufactured devices.
[Moto G4 Plus Questions & Answers] tech virus:
as i said its jus the voltage causes ghost touches... especially the change in rate of flow of current by turbo charger when the battery gets heat turbo charger will reduce the flow and will charge the device again after decrease in temp again the current flow increases....this causes ghost touch

u can use various charger. thing is the charging rate!
[Moto G4 Plus Questions & Answers] derausgewanderte:
Or your device is simply bad - like my son's, which works after they fixed it.
[Moto G4 Plus Questions & Answers] tech virus:
its not that device working gud after repair...may be your device wud ve been a defective piece and so its fine now after repair.... actually every moto g4 plus devices experiencing ghost touch

I understand that it's a problem, but we are told above that "every" Moto G4 Plus has the ghost touch problem, which simply isn't true. Also, I was pointing out in prior posts that it may not simply be the charger as somebody suspected. I come here to help, but I feel obligated to point out things that aren't true.

cheers
[Moto G4 Plus Questions & Answers] hite01:
You are right , it's not affecting all the devices but only part of several batches. You are also right pointing that this is not coming from the charger. Thanks for your time. It's been more than 6 months and there's still no communication from Leno except saying that this is not hardware but should be sent to support centers ...

One of my friends switched to a power bank recently for charging, and his ghost touches disappeared completely. Turns out, the voltage in his room fluctuates a lot. You should try using a power outlet with a built-in surge suppressor, or start using a power bank.

[Moto G4 Plus Questions & Answers] Shahbaz23:
Resolved: Ghost Touch

Hi all, I am having the same Ghost Touch issue while charging (only) with either Turbo charger or any other charger (tried various chargers at various homes :p). However this issue can be temporarily resolved by using a power bank as the source for charging. Apparently the main problem as to why this arises is some "earthing" (ground) issue, hence if u use a DC power source (like a power bank or UPS) rather than a AC source u won't experience any ghost touch at all. So if u don't want that customer care ****, u can simply carry a power bank and get going without any ghost touches :)
[Moto G4 Plus Questions & Answers] 3Rick99:
Well, i think it's a software issue, i have some random "ghost touch", even when the device its not charging, its fixed when you lock and unlock the phone. Or it's hardware issue?
[Moto G4 Plus Questions & Answers] ReeshabhRanjan:
For me only while charging. If the phone is unlocked before removing the charger, then it will continue the ghost touches till it is locked and unlocked.

Any solution for ghost touch?

Ghost...

Hello guys. I bought this phone from Amazon a week ago. I knew about the ghost touches but this was the only phone fitting in my budget at that time. But from the first day of its charging (with the turbocharger) it started having this ghost touches. They only appeared during the charge, The phone worked flawlessly when not connected to the charger. And the problem persisted even if I charged it with a normal charger. But after the 501 mb update (MPJ24 . 139-63) I noticed the Ghost touches has been reduced a lot. I mean before the update they were severe, I could not use the phone while it was charging. But now I am writing this reply while it's connected to a charger (normal charger not a turbocharger). Still it hasn't gone completely, It appears when I zoom in on the photos or use the touch for a longer period of time. Now I am more confused. I read the reviews, most of the people still have this problem even after replacing the phone. I am seriously loving this phone. It's a great experience. So do you think I should opt for a replacement or refund? Do this ghost touches get more severe in the future?
[Moto G4 Plus Questions & Answers] vinal:
I have the XT1644 and had the ghost touch issue often using a cheap charger with an 8" cord. I switched to a Moto X Pure turbocharger that has an attached long cord and haven't seen the ghosting at all in over a week.

Was an immediate improvement for me (that may not last). YMMV
[Moto G4 Plus Questions & Answers] sstamm:
So do you think I should go for a replacement? I don't have any other complaints with this phone except the ghost touches(Only when I charge the phone). And since the update the touches have reduced a lot. I have until tomorrow to replace this phone and I cannot decide weather to replace it or not?
[Moto G4 Plus Questions & Answers] vinal:
I've read some come back with same issue and might even be a refurbished unit. I was thinking of sending mine back until issue disappeared on my phone. I may regret that.

Hard to say if the inconvenience and success rate make it worth trying for a replacement.
[Moto G4 Plus Questions & Answers] sstamm:
Well I am still confused. Tomorrow's last day for the return. I have to admit though, Ghost Touches have been reduced to 5 to 10 percent since the update. I also found this thread about panels. Boe and lgd panels are used in our phone's display, the once with lgd having more severe issue like screen burn and Ghost touches while the once with boe panel are only experiencing Ghost Touches. I have boe panel and I don't have any issues like screen burn. Only Ghost touches. Here's the link

Hope this helps. It's funny that everybody except the phone's manufacturer Motorola have their own theory for this issue.

You can try using an earthed turbocharger.
[Moto G4 Plus Questions & Answers] darky_mtp:
Using an old Samsung charger or connected on a PC I never faced ghost touch. I once used another charger (no name chinese) and I had ghost touch.

I never used supplied charger (I don't want to turbo charge and wear out quicker the battery).
[Moto G4 Plus Questions & Answers] sstamm:
I will next time. But you know I've been experiencing this issue on both normal and turbo charger. I tried using Coolpad note 3 lite and Lenovo K3 note's charger but the issue still persisted. Still I will try the earthed turbocharger. Thanks a lot.
[Moto G4 Plus Questions & Answers] vram4891:
Go for immediate replace. I am from bengaluru , india, and i neglected replacing the phone with amazon and afyer 2 months ghost touch increased like any thing, even during regular use also it increased, (not only during charging),

I roamed around the se4vice centres and they simply say " software issue' after having big fight they replaced the display...again now during charging i am facing ghost touch...
[Moto G4 Plus Questions & Answers] Sebastian Ipe:
Maybe a solution?

Hey Guys!

Maybe I found the Reason/Solution for the Ghost-Touch problem. Motorola gave me the Information, that an electro-magnetic field interferes with the touchscreen of the Moto G4. I searched for the electrical source and thought if some uninsolated cable inside the device hits the back of the touchscreen then it could be the the reason for the problem. I found the source and I somehow tried to ground it. When I wrap a thin copper cable around the micro-usb frame (Like this: imgur.com/a/VkxkR) and touch the copper cable, the Moto G4 doesn't do the Ghost-Touches. Maybe someone can find a better solution because I think this is only a temporary solution!

Hope this will work for you too!

[Moto G4 Plus Questions & Answers] 701:
Mine suffers from this, but changing the charger fixed my problem. I use a HTC 10 QC 3.0 charger and a slow charger for the car. Charging the phone with external slow and fast (2,1, 2,4 amp) batteries bear no issues also. If you have a problem, just try a different charger.
[Moto G4 Plus Questions & Answers] sonvegeta:
I think I got a solution. It's the same thing as a Desktop: they don't work well without a stabilizer, and I think this charger can't regulate the voltage by itself. I bought one and it's coming, so I'll use a stabilizer and see if it works.
[Moto G4 Plus Questions & Answers] Sebastian Ipe:
What do you mean with stabilizer? Can you post a link?
[Moto G4 Plus Questions & Answers] sonvegeta:
https://image2.pricedekho.com/p/136...v-stab-13m-voltage-stabilizer-picture-big.jpg

It's a common pc stabilizer. Explaining: voltage isn't always the same, and it can have peaks above the necessary voltage and amperage. A stabilizer make the voltage stable always. Things like this are happening this charger and isn't with weaker chargers, so I thing it's better to use a stabilizer, like I would use with a desktop.

Probably This can fix it temporarily!

Fiddling around for a month now. One thing is for sure, there is something wrong with the Motorola Phones owned by Lenovo. Random crashes in Moto G4 Plus and now this 'Ghost Touch'

Here is a fix I recommend: (Found it after fiddling around, I hope this works at the cost of some battery)

> Go to Settings

> Battery

> Tap on More (3 vertical dots in top right corner)

>Choose 'Battery Optimisation'

You will see barely 2-3 services or apps with a title 'Not Optimised' (Means all other apps are optimised for battery)

> Click on the title 'Not OPtimised' and choose 'All apps'

> Scroll to alphabet 'S' to find 'System UI', tap on this and choose ' Don't optimize' (Warns about faster battery drainage, well you can check if battery really is draining fast or fine for your usage after a brief period of usage on this setting.)

Reboot and I am sure this issue wouldn't persist. But make sure if battery usage is a Hit, you can revert back the options to default.

Please let me know if I did miss anything.
