Touch screen extremely unresponsive when charging - EVO 4G Q&A, Help & Troubleshooting

So when the unresponsive screen when grounded issue came about, I didn't really notice the problem much myself. However, recently, and I'm not sure when this started, the screen has become horribly unresponsive when charging any time! Doesn't matter if it's on desk, in my hand, stock charger, 3rd party charger, etc., if it's charging at all, the touch screen only accepts half or less of my inputs, making typing impossible. Is this due to the last software update? Anyone else experience this issue? I would exchange the phone, but not if it's not going to help anything.

this happens to me when i use my cheap ebay charger

The fps lifting kernels fix this.

+1 for symtoms seen when using a wonky charger/cable.

+1 due to cheap charger - anyone know why this happens? is the OEM usb cable different spec from the cheap ones?

Hate to beat a dead horse, but the same happens when I plug my phone into the charger I got from eBay. Kind of disappointing, considering that I would otherwise be able to charge two batteries at the same time.

I notice this issue with the stock charger.

I believe the issue was when its not grounded..
Being plugged in is just about the most grounded your phone can get.
That's not the problem.

Starting to do it to me also now.

Just to be clear, this happens to me with the STOCK charger.

I'm having the same issue. i just chocked it up to the new kernel.
one thing i did notice is it seems to be intermittent. Yesterday night, it worked fine. this morning(conveniently when my alarm went off) i could NOT get the dismiss thingy to slide down.

Anyone else experiencing this? I do think it got worse after last software update. Would be nice if the next one improved things.

I emailed support, they did not say anything about it being a known issue, and suggested a factory reset. If that doesn't help, they recommended using my warranty. Would like to hear from more people before going through with the reset.

It happens to me when charging via outlet. Charging via USB connected to computer does not produce the issue.
I think it has to do with grounding.

Same thing happens to me! I noticed it with my aftermarket wall charger.

Bringing this back up, happens to me with a Stock charger.
Is it really the kernel? :\
@Person who said charging is the most grounded, the stock charger is not grounded ( in AU anyway ) and therefore it is the LEAST grounded.

ive noticed this happening over the past month or so. i've got to admit i've only really noticed this when its plugged into a usb cord i got off ebay. relieving to think it might only be an issue with it being a cheap cable and not the phone but i'll verify tonight with the stock cable.

I've been plagued by this problem for weeks and just discovered that it only happens when charging. I use the stock charging cable and wall adapter. I'm very, very happy to know what the problem is. I'm going to start testing this at various locations.
EDIT: I've tried this on both the wall adapter at work and on my work computer's usb. Same problem, though it seems worse when plugged into the wall outlet.

The touchscreen is fine on my sprint brand car charger and on the usb charger on my laptop. However, it starts missing taps when I plug my usb cable into my usb car charger. I'm going to best buy tonight to buy a different charger and see if that helps.

I have these issues as well with the stock charger and cable regardless of which kernel I use.

Evo charging lag?

This isn't a problem but more of just a general question. So does anyone else experience your phone kinda lagging or having screen sensitivity issues (have to press hard on screen to scroll) while having the phone charge? This is like a 50/50 thing sometimes it does this sometimes not. So post your experiences with this

Yes indeed. In my case, it's caused by my HTC USB cable that came with the phone. When I use the charger from my old LG ENV3, i never get that problem at all. As soon as I switch to the HTC cable, it's nearly un-usable whilst plugged in. It's odd, because the HTC cable works fine for charging and transferring data, so I don't know, but there's something wonky with it.
Hmm interesting

Nope, you're not. It can certainly become rather annoying if you're trying to use your phone while it's charging.
Yea, using swype is IMPOSSIBLE when plugged in.
I never used to have this problem before, so I wonder if this is something that comes with age of the phone. I've run all kinds of roms/kernels and never had this issue until maybe a month ago. But I think I've successfully narrowed it down.
You need a charger that outputs 5v at 1000mA. Any more or less and you'll get the wonky response. I have an 800mA and a 1.5A charger at 5v and I get the laggy response. And I took it a step further and noticed that I get maximum charging speed (regardless of kernel, I've tried stock and custom/SBC kernels) with a 28/24 AWG or 24/24 AWG micro USB cable. If you still rock the stock HTC charger/cable combo you should be golden.

i don't think its from age of the phone because i just got my phone in december (hw 0004) and i am still using the stock htc charger/cable. so idk its a mystery. nice work finding all that out tho its good to know that i am not the only person who experiences this haha.
I only get the problem when I'm plugged into A/C power, but not when I'm plugged into the D/C car charger... I think it has something to do with how the outlet is grounded. Maybe the touchscreen gets confused by getting grounded through the charging port rather than through your body. I'm basically making this up based on hazy memories from an E&M class I took about 8 years ago, but I think it's close. Anybody with any actual knowledge care to correct me?

Stock Cable > Hard to Plug on the Charging Port of the Phone

I just purchased this unit. is it normal that the Stock Cable is Hard to Plug on the Charging Port of the Phone..
i need to try so many times before i can plug the charging cable to charging port of the phone before i can plug it successfully. i'm thinking of breaking the charging port if this is the case? Anyone who have the same concern? Thanks

I noticed this as well. hopefully if something gets broken its more likely to be the connector on the cable than the charging port. I have tried a few other cables as well and all are pretty difficult to insert.
Well the way I see it would you rather have it flop around and be loose, or have a night tight fit?
On a more serious note I had the same issue when I first recieved my F400S. After a week or so it got better, you can always try an older micro usb cable thats more broken in to avoid this issue.
when i first got the phone it was like what you've desribed. but after a while, it wasn't an issue anymore, i guess its a good sign that the phone is brand spanking new.
Same for me, hard To plug in ...

Hi,
I tilt the usb-connector up (just a bit) while plugging it in.
Greetz
It requires a downward angle tilting towards the device to insert.
Same for me, but once you're using qi charging and Wi-Fi file transfer, you'll hardly ever use the port.
got it! it was like virg** phone. haha..
wow same issue here.

Only way to get it in is by tilting the cable downward. Tried few cables, they are all doing the same thing. Exchange perhaps?

Tilting the cable to plug in seems to be the norm on pretty much every G3. I doubt exchanging it will help.
Once you've done it for a while, it should become pretty easy to do.
Tilting the cable and just dealing with it are fine, but what happens when you stay finding usb cables that don't want to charge your G3 properly? I have one (very nice) 10ft cable and my phone plays a game of connecting and disconnecting while trying to charge with this cord. This courts does not give me the same problems on other devices. However the G3 charges just fine on all my other cables. Not using this cable is an obvious answer but i worry that the problem could get worse and what if I start having problems with other chargers?
For now, the solution is to tilt the cord slightly downward (or upward, depending on your perspective) as the port is just sliiiiightly more flush with the opening. My advice is to get used to doing this. A broken charger port is really a PITA, so taking an extra 2 seconds to plug it in is the prudent choice. My dad gave me a lot of good advice when I was growing up, and one of the gems turns out to be "don't force things."
As mentioned, once we get some wireless charging back covers on a more accessible basis, we'll all just use wireless charging and never plug in again. Except in the car.
The cable from my old GS4 plugs in very very easily. I haven't tried charging with it tho. I use it mainly for usb mtp.
Posted from my LG-D850
Difficult at first. It did get better for me though. I too thought i had damaged it or that it had shipped that way. And I also thought I was just breaking it more each time I charged and contemplated exchanging LOL. Make sure cord is facing the right way first (im still trying to put it in upside down sometimes), then you do have to tilt it down a bit to get in initially and then it tilts slightly up before fully inserting. It was very diificult to do the first couple days. Day 5 and its way easy. Hope this has helped and put your mind at ease This is my first Android phone and i'm luvin it!
the past new phones i had. was always hard at first to plug it in.
just gotta lube it up
Any new updates on this? I guess tilting the cable a bit is working, but will it ever get to the point it will go straight in? It really appears that this is not a defect but a LG design for the port.
Sent from my LG G3
still the same.. still virgin after many charging cycle
I agree with what was previously stated, after a week with phone, I've become used to putting the cable in. I'm pleased with the tight fit as I've had devices where it feels loose and unsecured.

G4 Charge/USB port issues

I've had my G4 since almost launch day and within weeks the supplied USB cable stopped charging the phone. I thought it was a cable problem, but it worked fine with other devices.
I tried other cables with the G4 and these still charged it so I thought nothing more of it until charging degraded with every USB cable I own to where the phone would only charge 20-30% during an overnight charge and the phone would frequently not recognise it was plugged in at all. I contacted LG who did a repair under warranty and all was fine.
I've now had the repaired phone back for about 3 weeks and the same problems are starting up again and it's only a matter of time until I am forced to return again for a repair.
Is anyone else having similar problems? I thought I may have just had an unlucky manufacturing problem, and the LG reps confirmed that to repair my phone they basically replace all the internal circuit boards and components rather than just replacing the individual component that is faulty (in this case the USB/charging port)
Basic debugging includes asking stupid questions, so please forgive but still answer any of those
Are you using a different charger? If so, check if that one is within specifications and if you do send in for repair again, use a different charger.
Are you propping up the device at an odd/weird angle or in a dock of some sort with the cable attached?
(As they replaced the entire print, it's probably not this, just the USB-micro port bent or broken.)
You could double check the wall outlets being used, there might be some kind of electrical problem there.
Either using all kinds of fancy electical testing gadgets, or stick a USB light into the hub or charger, does it flicker?
When sending it back for repairs, did they check the stock charger as well?
Hopefully these questions help you find any logical or plausible cause.

Hi FreezyExp,
1. I am using the standard charger that came with the phone, but this has not been repaired/replaced. I have tried other chargers too, but all the same issue.
2. No weird propping up or anything like that. If I hold my phone while it is plugged in it is constantly vibrating as the charger connects and disconnects, and if I place it on the desk to charge I have to ensure that I have at least 3-4" of cabe "on the desk" to give it enough support to make the connection.
3. Wall connection is fine and I have tried it with a range of outlets around the home, both with extension sockets used and plugged directly into the wall and there is no different. No flickering light when using a USB light either.
4. When I sent it back all they asked me to return was the main section of the handset - so no battery or rear cover, no cables or chargers etc
It does seem to be the same issue as last time, a USB connection becoming loose from the main motherboard, but it seems weird that I have had the same issue twice in the space of 4-5 months.
I've been having some sort of problem with my G4 usb port. If I plug it in to a computer, it will lose connection and get a connection again if I barely touch the end of the cord at the phone end. I've tried many different cords and different usb ports on my computer, but it still has problems.
I can't fast charge, either. When I plug it in to fast charge, it actually starts discharging even faster. I've had some extreme battery life problems, too. It drained from 100-36 the other night with everything disabled, and it's been doing that kind of thing a lot lately. I'm guessing that the charging port is what's messing up my battery life because it won't charge correctly.
Never dropped it or anything.
I got my G4 on January 24 and my USB port has also failed. I am getting a replacement from Verizon, but am concerned that a six month old phone has this issue.
I also own a G4 H815. A while ago the phone started not receiving any charge from the cable and I would have to prop it up from right under the cable's micro usb end. Thought it was because it was bent inside the port and not making connection with the cable so I had the port replaced. Now I'm experiencing the same problem and I think it might be the cable that's already gone kaput and is effing up the port itself. I took the phone to the same place to get the port replaced again and bought new cables (I lost both the original adapter and the cable, which were charging slow anyway. Now using a 2A Asus adapter which works great) and when I asked the guy at the repair shop, he says it's a chronic issue with G4 devices. I don't really understand how it would happen twice in just a few months even with a new charger port. What should I make of this? Did they replace my port with an already faulty one, cahrged me full price and now trying to sell this bogus or am I really doomed with this phone?

Erratic Charging

As of today, when I plug in the charger it will show the Dash charging symbol, then cut in and out a few times before it stays charging. I updated to 5.0.3 yesterday if it means anything.
Is this normal? I couldn't find anyone else reporting this.
It happens to me too, even back in Nougat. It starts as regular charging and then a couple of seconds later, switches to Dash. I figure the delay is due to the charger and phone figuring out how much battery the phone has left to determine how much amps to push through. Dash charging operates at different amperages depending on the voltage of the battery. Thing is, that either that never seemed to happen on my OnePlus 5 or I never noticed it, but on the 5t it does.
I think I'd be more comfortable with your issue. When I see the charging LED flashing and the charging notification disappearing and reappearing, it's unsettling.
My Nexus 5X would do this as pocket lint would build up in the USB port, preventing the USB cable from fully seating. Every so often I would have to take a small needle (something non conductive would probably be better) and carefully clean around the edges to pull out the lint. I was always amazed at how much build up really does end up in the USB port and headphone jack.
I used to have that issue with old micro USB ports and this definitely reminds me of that. I'm concerned though because I've had the phone less than a week and the port is clean. I also get that satisfying 'click' when plugging in the charger.
Ah, well that probably isn't your problem then. I would try another charger and cable to try and isolate the problem between the phone, cable, and charger.
Remember the OnePlus cable is unique, you can't use just any USB C cable with the dash charger. I believe IIRC the OEM cable has a 10k resistor, while most in spec USB C cables will have a 56K resistor. However you can use another charger and cable and see if it cuts out as well.

We have three 5t phones here all purchased last week. I tried all three charges that came with the phone and it does this with each one, all plugged into different outlets.
We updated a 2nd one to 5.0.3 and now this one also has the charging notifications flicker on and off about 7 times before it stays charging normally. I haven't tested the 3rd yet because it was fully charged when I came home.
It's odd that it is two of our devices now doing this and I haven't seen anyone else with this problem. I would assume that we got phones out of a defective batch, but they were definitely not doing this before the update.
Just an update, I wiped system and cache and it still does this.
It didn't do it when I plugged in at 88% immediately after wiping. But it does do it when I plug in at around 30% like I usually do.
I'm wondering now if they all do this after the 5.0.3 update and no one really notices.

S9 Moisture Detected in Charger Port message, port is dry and clean, never been wet.

SO yeah, I've seen where people have had software issues causing this on the Note 8, and S8 models, is it a bug that crept into the S9 as well? The tech at the Sprint store verified the cleanliness and dryness of the port, thinks it's the port, and they won't have parts to fix it for probably a month or so. I REALLY don't want to send it in to be fixed, so I bought a couple wireless chargers.

It it showing constantly or only when a cable is plugged in? If it's with a cable, have you tried other cables? I had my phone give me that message earlier today when plugging in an incompatible hub. The hub wasn't even connected to anything.

Yeah, tried rebooting, wiped cache, power down all the way, multiple times. Tried plugging the cable in while booting. It looks to be charging while plugged in and powered down.
So, the message went away, and it would charge with 2 different chargers, normal speed, not fast charge. Would not work with a charger I have here at home. None are Samsung chargers, but all are QC 3.0, which will report as fast charging on the phone. Then today it charged fast in the truck, and the one at home works, but only slow speed.
I'm not going to stress over it as long as the fast wireless charging keeps working. The battery life is more than enough to get me through a day, and I'm ordering stuff to integrate wireless chargers into the vehicles.
Thanks for reading and trying to help!

I probably missed to ask before, but are you sure you are using the original cable, together with the original power charger?
As stressed by @DeadlySin9 the problem may be the cable. Try other cables.

Yeah, I had tried the original cord and charger. whatever it was effected the phone before even plugging it in. The message would be there in the notifications, then plugging the cable in would set off an "alarm" telling me to unplug it and let it dry.
A couple weeks later and it is working just fine, charging with pretty much any cord, and charger. Ugh. I hope it stays that way! LOL At least Sprint DID give me a pretty good discount on a 2 pack of wireless chargers, which is what I use most of the time, now.

Thumbs up!
So, I've had this problem with my new Galaxy s9 as well. Here's the specifics - this only happens IF the phone dies from running out of power. If I let the battery drain on accident, I plug in the device...new cord/charger, original cord/charger, doesn't matter...and it shows the charging symbol for just a second, and then warning there's moisture in the charging port. There's not... If I set the phone on top of a wireless charging pad for a few mins, it charges just fine.
All I have to do is get 3 - 4 % so I can power on the device and get to the home screen. If I can get to the home screen, I can plug the phone in with the cord/charger and no problems.
I just did a warranty replacement because this problem is real annoying. I don't let the phone run out of power often, but sometimes when I'm traveling for work or camping with scouts, it happens. So, before I sent my old phone back for the warranty swap, I let the new phone run out of power and then tried to plug it in. Same error!!
If anyone has this problem follow this trick. "connect the charger half to the charging port." that is it. works fine to me..
