Touchscreen issues whilst charging - Nexus 6P Q&A, Help & Troubleshooting

Hello
I bought a 2nd hand 6p yesterday that came without a charging cable (it was super cheap). I got a 3.1 USB-A to USB-C data sync cable, from a reputable shop, to charge it and have put the phone is a TPU case.
The issue is when I am charging the phone the screen becomes very flaky. Double taps and sensing the wrong spot. I have trouble shot this and found that if I touch an exposed metal part (through the TPU case) the screen comes back to normal.
My Question is, does this mean that the USB cable is dodgy? or is it standard behaviour when insulated in a case?
It appears to be similar the an issue that 5x users had when fast charging.

Car charger does not work

Q: Suddenly my car charger (cigarette lighter plugged) is not working anymore. After 5 mins. my device stops charging..... is there anybody having the same problem and knows how to solve it?
If it's after a period of time maybe a battery contact issue?

If you've already read the sticky posts relating to car chargers and your (mystery brand) charger isn't one of those, then maybe your phones battery terminals and connectors need careful cleaning with a cotton bud moistened with contact cleaner or IPA. I had a problem with my mains charger ceasing to charge my TyTN II after a minute or two a long time ago and after cleaning as described, the problem went away. Be sure not to spray the contact cleaner or IPA onto the phone or battery, only the cotton bud/Q-tip and then gently rub that on the spring contacts and battery terminals. How does charging via mains adapter or PC USB port go?

It still could be a battery contact issue as voltages may differ slightly when using the car charger compared to the other forms of charging. As an example if the Kaiser is set to stop charging when the supply voltage drops below a certain value and the car chargers voltage is lower to start with (and fluctuates with normal driving/electrical usage) then that may explain things. It's well worth doing this cleaning every so often anyway as a matter of course so give it a try and see what happens.
Additionally, could heat be a factor eg if it's sitting on a hot dash or near heater vents (the device is designed to not recharge above certain temperatures)?

Thanks for the advice, i will give it a try
if you have any adapters that allow for another usb input, nice a headphone adapter, or the HTC Multifunction Audio Cable YC A300, a ycable or anything with a USB in, try that first.
if that doesn't work, take the unit into your retailer and they will give you a new (or refurbed) unit, as your USB port may have a pin or two out of whack.
This may be weird, but my tilt used to charge just fine from most USB chargers(car, AC, usb cords). One fine day it quit charging off most chargers except the official AC charger from AT&T. I tried to fiddle with the USB pins inside as one looked like it might be a bit bent/damaged. No luck.
However, yesterday I noticed that My Settings->System->Power->Advanced settings page had following option checked:
'When device is turned on, do not charge the battery when connected to the PC'.
Once I unchecked it, it started charging of PC USB cables (obviously), but strangely enough also charging from my car charger(s). Hope this works out for you or someone else...

It is probably because your normal USB pin 4 and 5 in the cable of your other chargers are not shorted to signal that there is no data connection. So your phone thinks it is connected to a PC (or a device which might send it data), hence not charging the battery according to that setting
I have a similar infuriating problem, i have had a MDA VArio III for over a year now, had an issue with my last one and had a replacement issued in October. Now i have used the Brodit active holder (ciggy lighter version) since day one over a year ago and wit the new MDA as well. now all of a sudden phone will not charge in the holder, borrowed a friends active cradle still no charge, used a no brand usb ciggy ligther charger and charges fine!!!!
When phoe n is placed in the holder orange charging light comes on but phone does not charge and the light goes out 5 mins later!!!
any ideas anyone???
thanks
Matt

Problem solved - Pin 5 on my phone was ever so slightly out of alignment, bent back into place and all is now well! strange it only affected the brodit holders, nothing else!
Car charger failure explained
I also experienced this same problem and actually broke my phones mini usb plug in frustration at lack of charging. Got it fixed again though
The reason for this problem has become apparent since my phone was repaired. In your car, like my car when the heater is switched on it will gradually heat up the cigarette lighter socket. My charger cable like yours has a thermal safety circuit built into it. So when the ciggy socket heats up the heat is transferred to the charger plug and breaks the elec charging circuit. You might see me driving around London with my charger plug hanging out of my window (to cool it down) on a Winter's day!!! Honk if you do.
The solution would be a cheaper charger without the thermal circuit built in. Go into Maplins or PC World and ask them for that..... They dont know what your talking about, because I have already tried.......! Good luck
You just need to make sure to enable your phone to charge when connected to PC.
Start->Setting->System->Power->
UN-CHECK the box that said "When device is turned on, DO NOT CHARGE the battery when connected to PC"

slow / laggy when charging S2

have anyone got issues with S2 when plugged into power?
ie when I start recharging direct from 240V adapter, my S2 started getting VERY laggy and slow.
It immediately goes back to normal response when I unplug power.
I have never problem like you

Try using an alternative charger...probably your mains charger or the usb connector on the charger is damaged.
I'm pretty sure its a issue with the s/w as I have used the charger on another phone without any issue.
unless its one of the apps I'm using, not sure how to narrow it down.
mtrax...
I have the same issue.
You´re not alone...LOL
FYI the common issue I have when plugged in is that its not easy to unlock screen, takes me a 2-3 swipes to unlock screen and after that it seems that it ignores every other key press..
Any one reported this to Samsung? I will try to log a ticket to see what happens.
Try do a multi touch test while its plugged in see if the screens acting funny.
how do I do a multi-touch test?
what will that prove? as the screen works fine when unplugged.
I have the same issue but only when charging with the usb lead (with usb power adapter) instead of the standard mains charger. Think it might have stopped now that debugging is enabled and the Samsung kies screen doesn't come up when i connect the usb.
Sent from my GT-I9100 using XDA App
Took my phone 2 hours to charge from 36 % to 100 %
note this issue doesn't occur when charging via PC ONLY via 240V mains, but let me try with USB debugging on.
edit tried USB debbuging still has issue.
Note is the 240V USB cable different from a normal USB cable? ie perhaps the device thinks its a PC connection
the phone is laggy because of the electrical interference from a faulty charger or some other electrical equipment in the near vicinity...
Please note that actually the capacitive touchscreen becomes laggy not the applications/services...
keep it away from the electrical interference...use the samsung original charger..gud quality USB cable....and the issue will be gone... for sure
looks like its the charger, the A/C adapter I got with the phone was UK which is why I didn't use it to begin with, but tried the samsung one with a UK/AU adapter and its fine..
hmm who would have thought that was the issue...
interesting it didn't affect my other HTC phone.
Same issue here, but something special:
I ebayed another charger for my sgs2, original samsung one. Same serial number, same description, same style.. but i got the charging problem only with the new one.
With my original charger (the one, which was delivered with the phone) works fine. No slow and no lag.
The new one was about 5 euro, seems to be an original...
to demonstrate my point that its the electrical interference from the dodgy chargers onto the capacitive touchscreen... do this and report back...
plug the faulty charger onto the socket BUT DO NOT charge the phone with it...
keep the phone near to the charger wires etc....(not in charge)... you will see the screen lagging sometimes unresponsive...
now move the phone away ...it will work fine..
you can keep on using the dodgy chargers for charging...but use the phone only after it has been charged and is away from the charger...

I am not able to reproduce that with my original charger. There is no lag or any other problem. Switching to my second "original" (ebay 5 €uro) samsung charger leads me direct to the lag and your description. First i thought my second one is not an original one, but because of your description there seems to be a diffrent quality on the original charger depending on it production date.. unit.. charge.. or whatever.
I bought a sgs2 from the UK, and have a UK to AUS converter on the stock charger and I have no lag when it's charging or near chargers.
Sorry. Not a problem here. Writing now and plugged. Very responsive.

The electrical interference with the capacitive display is bullcrap since it needs electrical properties to respond. So it depends on whether your body has enough electrical properties.
So back to the point:
It is due to CPU reducing the clock speeds to prevent the phone from overheating as the battery itself produces enough heat anyway.
Many other people may not notice it since they may not perform intensive tasks while the phone is plugged in and the variation itself is also almost unnoticeable.
I have the same issue but as I said, it's almost unnoticeable to even bring it up in this forum. I haven't done any testing myself to prove this, but the same safety feature is implemented in most modern phones.
I have the same issue - I also had this issue with my Atrix.

battery/charging issue??

I recently purchased an n9005 (note 3) second hand. Everything was fine except it looked like the charging module was on the way out. It wasn't inclined to charge at all with the usb3.0 connector and I had to wedge the usb2.0 connector at an angle. ordered up a replacement charging module - and swapped it out.
All good ...or so I thought!
A few weeks later and the phone shows as 'charging' but it may or may not be charging in reality! I always leave it charging overnight - but now I simply don't know whether I'll wake up to it being completely flat or charged.
I'm not at all sure whats at play here - but it's definitely not the same problem as I had with the charging module. There's no necessity to have the cable inserted at an angle or anything like that.
other than confirming that, I'm at a loss as to what's at play. Could it be some sort of android issue...or....could the battery itself be on the way out?
Any troubleshooting steps or suggestions would be very welcome.
I was away over Christmas/New Year - in Spain. During that time, I recharged using the old micro usb cable - via the mains - and also via a power bank. With both, there was no charging issue whatsoever.
When I came back home, I tried to charge via the mains (with the micro usb cable and the usb 3.0 cable) - but same issue.
Is it possible that the charging module that I bought online and installed - is geared towards continental power supply only - and not the irish power system?
In the meantime, I've simply been charging the power bank up - and in turn, charging the phone via the power bank.

And secondly the phone is charging really slowly and not show "fast charging" only "charging"
i test with Ampere and i get very low mA (picture added)
i tried lg g5 charger but again the charge is slow and show "charging" only but it's charge in Both sides

thnx and hope for help
My guess is a gummed up port. Use a magnifying glass and bright light to inspect USB port for debris, corrosion, or damaged pins on both sides of connector. You may also notice some pins less shiny than others. They're dirty. Or take pics of the ports with a good camera and zoom in. Do the same for the unplugged cable. Clean by turning off the phone, dipping toothpick in isopropyl alcohol and wiping pins with toothpick. Allow a few minutes for evaporation and give it a try.
You could do a RMA
If it's charging on both sides with one cable and not the other, it's probably the cable. I recently had this issue of slow charging on my wife's phone and found the best way to solve it is with amphere and grabbing all the micro USB cables in the house. I ran amphere, and plugged each cable in and let it test then used the one with the best draw. Ironically the one with her phone (LG g3) was among the slowest at about 200.. And the one for her Bluetooth earpiece came in at the highest at just over 2000! I'm guessing it was a defective cable cause we had previously rarely used the one that came with her box cause she had the Galaxy s4 cable still as it was like almost 3 feet long! The Bluetooth one is alot shorter but charges so much faster she just leaves it be for a bit and can charge it fully in alot less time. Difference is a couple hours versus overnight. Give it a try with whatever ones you can find around the house!

USB connector not sitting snuggly in the USB port?

Occasionally since I got the phoone I've noticed that the audiobooks I've listened to have suddenly stopped, and prompting me to press play again; it always seemed to happen when I had a hand in my pocket, so I probably just assumed I had touched the screen or something. It was annoying, but I just continued on.
Then late last week after it happened while I was at my desktop and just moving the phone, I investigated a bit more closely.
I found that I could wiggled the headphone USB dongle, and the fit was not as solid as you'd expect (of course, I hadn't really checked this earlier, just putting in and taking out USB connectors up to this point). As I wiggled it, the audio would stop as if my headphones were disconnected and reconnected. Which must've been what had happened before.
Then I checked with my charging cord. Same kind of fit, I could wiggle the connector a few degrees. Enough for me to raise some concern about it being a faulty USB port, or it having somehow gotten loose in the shell.
This is probably RMA worthy, I'm guessing. The question is what will OP do? Replace the whole phone? Repair it (repair what exactly, I'm wondering)? I've not dealt with their support before, and I couldn't really find any suitable thing under their repair service categories.
Could some people check how snug their USB connector fit is and report back to me, so I could find out if this isn't how it's supposed to be?
First check your USB port for lint. I typically use a needle to clean mine out (Don't short any of the pins if using a metal needle). Lint will prevent the cable from fully seating and cause it to feel loose.

The USB port is totally clean. Couldn't even spot any dust particles under a bright light.
I know the 3.5mm headphone jack isn't technically rated for as many cycles as a USB C connector but I still feel it held up to abuse like being in a pocket better than any type of USB connector.
