[Q] Weird touch behavior while charging the One E8

Hello there folks,
I notice that the touch input of my One E8 behaves weird while charging. It responds to some other input for a specific input. For instance when I'm unlocking my phone and I press 3, 8 or 9 is taken as the input, or when I press send on WhatsApp, the menu gets activated.
The issue is not specific to any app and is seen in general throughout the phone while charging. What is strange is that I see this issue only while charging from a USB charger either connecting it to the wall plug or a USB port on my PC (happens in both cases).
I also have a charger that has a direct cable (no USB port) and if I charge with this, I don't see this problem. Any one else seeing this strange issue? Any solutions to this?
Thanks in advance

Touch issues occur when the phone receives an incorrect amount of voltage (usually high) from the supply while charging. It's best suggested to use the supplied charger or one of similar readings to not encounter such issue.

Hello there,
I see the problem with the supplied charger even if I connect the cable to a USB port on my PC. But I don't see the problem on a Samsung charger which is a direct one (not having a USB connectivity).

You might wanna talk about this to the customer service then. Chat online on the HTC website, or visit a sevice center.

i have the same problem. i turned on pointer position from developers menu and ghost touches appear mainly near the app drawer icon location. it stays like this until i lock and unlock the phone. also while typing pressing the space bar presses another letter with it. it's almost impossible to type anything. this problem appeared just today without changing anything or installing new apps.

Same problem here and mine s6 is only 26 days old.... support told me it's the cable but refused a replacement... what the hell right?

I have the same thing and have tried a few cables. Did you get to the bottom of the issue? My laptop is a dell xps15 and it happens with W8.1 and Mint17 (on the same laptop).

its the cable.. same issue here..when I use a ps4 controller-cable i have no problem

Yea... I think it has a lot to do with the placement of the port on the phone and and a filmsy input. I tried tried a sturdier cable and it works waaaaay better.
Samsung support did offer to send me a prepaid envelope for my cable. ... then wait 2 weeks for testing... then if it was found to be defective a replacement would be shipped free of charge, but if it was defective due to user abuse then they said they'd send me a repair bill........... SERIOUSLY wtf?
I'm not kidding, this was their solution when I spoke to support.

Well it really was the cable, went out and bought a new one, exactly the same and it works fine, so the one i got in the box was faulty, after some googling it seems this has happened to a fair bit a of people already,
i still use the crappy cable to charge with... although it did stop charging half way through once :silly:

I tried this and still it doesnt work. I changed the cables , I changed the PC which I am connecting to and still no fix. I keep getting disconnected continuously.

I'm having the same problem with Galaxy S7. It keeps disconnecting data after it has been plugged in a few seconds. It's not a cable issue, I've checked on 8 different cables.

Flash a different ROM. I had this on my s6 e+ on stock nougat. I went to Dr ketan ROM and it stopped

I heard it could be due to using a fast charging cable. The phone attempts to draw out more current than the USB port of the computer allows, forcing it to disconnect/reconnect repeatedly. Try using an older/less-current-rated cable. Alternatively, if you don't actually need to access the files and are just charging the phone, you can go to Window's Auto Play (search in start menu) and set your phone to "Take No Action"

I wanted to throw out a few other tricks to try, for whoever comes across this old thread when googling.
I don't 100% have an idea of why this happens, or why this worked, but it did.
First thing is, the cable really does matter. If you're using a cheapo cable that doesn't do fast charging, or a data-only cable, get a nice cable. If you're using a nice cable, try a non-fast-charge cable or the one that came with the phone.
My fast-charging cable has worked for a while but I recently tried to transfer a large 2 gig movie to the phone's secondary SD card, and it kept disconnecting / timing out.
What worked for me is go to developer options (google it, there's some code you have to enter to unlock these settings) and then usb debugging. It was disabled and I enabled it. The transfer then worked smoothly.
Weirdly, another transfer right after did NOT go smoothly, and the fix for me was to disable usb debugging, then enable it again. Then the file transferred normally, even though it took a few minutes.
Lastly, one file refused to transfer that was sitting in a particular folder. I'd get an error instantly. The folder was the cache folder for a popular video downloading app. Even a tiny text file from that folder, refused to copy. But files from other folders worked. I finally figured out that for whatever reason, the phone (or maybe windows) didn't like copying straight from this folder. Not sure why. Some permissions thing? Anyway - I copied the file I wanted from the cache folder, to a folder I use all the time. Then from this new folder to the phone. Worked smoothly, no error.
Hope these tricks help someone.

Galaxy S6 charging issue

Having a weird issue with my GS6. Unrooted and has been working perfectly. The other day I noticed when I plug the charger in, the screek flickers and goes black & some female voice starts rabbiting on about Gear VR. My phone stays in a black screen, doesnt respond to anything and only works when i force off & turn back on. I then check the open applications & Gear VR Setup Wizard is the first app thats open. Checked in application manager, won't let me disable these (options greyed out).
Any ideas? Tried clearing cache, yet to try a backup & full reset as phone does not want to connect to computer either. Still charges when connected, just doesn't show up in the file manager.

I have the same issue with my device.. what did you do with yours ?

I managed to figure it out. Basically it was down to a metal frame type case I had on my phone at the time. When this case was on & the cable was plugged in, it must have caused some sort of short when the metal from the cable made contact with the metal case, tricking the device into thinking there was the galaxy gear vr headset attatched.
I removed the case. Now every time I plug in, the phone charges normally. Every time I plug it into the pc, the file manager shows up. Back to normal operation & no other signs of the Gear VR application.
TLDR: Metal frame cases interfere with the micro usb cable connection.

I took it to service and they changed the charging port. It was still in warranty period. Now everything is back to normal. I hope it stays this way..

Smashed screen/backup question

Okay so, the screen on my Z5 smashed, the LCD is fine but the digitizer doesn't work at all. I was thinking I could USB OTG a mouse, but the device isn't picking anything up. Quick google and I found that you have to do detect USB device in settings, however I can't touch the screen to do that. I'm trying to back everything up and wipe the device to sell on for spares/repairs but I can't do this because I can't touch the screen and I can't plug in a mouse.
I tried using okay google to turn on bluetooth and connect to a bluetooth remote but I have an alert on the screen about updating which is blocking okay google so that's not working either.
Does anyone have any suggestions?

Yea it's an old thread and everything but it would be nice to find here answer as well.
Since the phone can't be properly controlled without screen or external devices.
And OTG connection have to be activated in the settings it looks like there is no much else to do about.
Well fortunately there is at least one more easy way to activate usb OTG connection.
All you have to do is:
- Turn off the phone by holding power + volume up button
- While phone still turned off connect usb device with OTG cable
- Power on your Xperia Z5 and you're done.

Unable to connect to PC in any mode

Hi all, I'm afraid I already know the answer to my question but I'll still ask if there's even a slight chance to get this fixed on my own.
I had this issue on Android 8.1 where my Pixel kept saying "Supplying power to connected device via USB" even without anything connected to it, (it started doing that one day without any reason) tapping the notification allowed me to switch to "Charge this device" and then turn on MTP mode, battery life was terrible but I wasn't that much bothered by it because I am an Android developer so I kept it connected in USB Debugging mode most of the time anyway.
When I got the notification for Android 9 update I decided to update hoping it'd fix the USB issue but after the update it now always says "Charging connected device" and tapping the notification does bring up the "USB Preference" screen and it allows me to switch to "USB Controlled by this device" and it starts charging but there's no way to switch "Charge only" mode to anything else, ADB does not see it, fastboot does not see it and there's no persistent notification on the phone about it being connected via USB at this point (in any mode). My understanding is that this is a hardware issue but Oreo still allowed me to workaround this and get the USB debugging connected.
Is there anyway I can get back to Oreo without using fastboot flash or any other solution to this?
Thanks for reading.
PS. I'm on Ubuntu but I can access a Windows machine if required and bootloader is already unlocked.

I'm curious if you're able to connect to a USB OTG storage device.

I'm having this issue connecting it to my windows 10 laptop.. the cable recognizes it.. starts charging.. shows option on phone to change type of connection.. but not matter which one i change it too, the computer will not pull lit up as a drive to see the files..

Same here! I plug the cable into the Windows 10 computer, I even can change the mode from charging to MTP file transfer, but the device won't show up in the Windows Explorer. It appears under connected devices though.

My Pixel 2 XL would not connect to PC for file browsing if USB debugging of Android Apps was enabled in developer settings. Didn't matter which option I chose to connect. IDK if that is expected or not, but it took me a while to figure out. Happened Spring 2018, idk if Google fixed it.

I don't think i've tried to turn that mode off.. i'm so used to needing it on for the computer to recognize and connect to all my previous Android Devices.. thanks for the recommendation...

Couldn't find any OTG cable to try that but strangely enough a few days back I connected it to PC for charging and Nautilus popped up, same cable, same USB port and it started working all of sudden. Did verify with a couple of other cables and different ports and everything is working fine since.
"Charging connected device" notification never appeared again, only thing different (when it started working again) was that I was out of the air conditioned room most of those days, might it be moisture or something like that?
I'm back to my normal routine for a few days now and it's still 100% normal, will have to see if it stays that way.
Sorry for late response.

Here's an update in case someone else runs into this situation, I can say this with 99% certainty that is caused by the blackish residue build-up around the USB port over time. It's not too much that it's visible just by looking into the port but it's enough to make the device behave like this.
Here's what I did to get rid of it, took a match stick (don't use anything metal) and broke it in half making a sharp edge on both broken pieces, took the non coated piece and inserted sharp edge in the bottom side of the port and gently wiggled it around while applying some pressure towards the connector (just a little bit, make sure you don't break anything), did this for about 45 seconds then took out the match stick and the part that was touching the connector had turned blackish (I guess this is when you know you have 'cleaned' it enough?), repeated the same process on the top side of the port with a new match stick piece (guess you can use the same one after cleaning it with a tissue), the only difference was that this time applied the pressure in opposite side (other side of connector), device was on during all this time.
It builds up again after a while (~3 months) so I had to repeat the entire process again when it started doing that again at the start of December but it wasn't that annoying this time because I knew exactly what was wrong and how to get rid of it, device is still working fine 100%.
I'm simply sharing my experience and not encouraging anyone to do this but if you do decide to try this be sure not to use anything metal and don't break the connector inside the port (turning the device off would be a good idea too) and you'll be fine and if something does go wrong I won't be responsible.
