Random screen behavior while charging

It's probably easier to show what's happening with a video:
This happens when charging my phone. But only when placed on a hard surface.
Also when the phone is resting on a surface, it doesn't respond to my touch input.
It acts as if there is an invisible hand touching the screen in random places very rapidly.
I hope this isn't a defective screen, because I'm sure this isn't normal behavior.
My problem is almost exactly the same as this: http://forum.xda-developers.com/showthread.php?t=846941, but the explanation doesn't fit in my case, as it's very hot here (high 30's C), with almost 100% humidity, and the phone isn't the same as mine.
Has anyone had a problem like this with the DHD?
On a side note, does anyone else think of "Dial Home Device" from Stargate when they see DHD, or is it just me?

Mine started doing this a while ago. Also only when charging, and only on a hard surface. Bit annoying, but I can get round is easily. Would be interesting to know what causes it though...

Mine does this when I'm using a cheap ebay charging cable. It's ok when using a genuine HTC cable.

Just tested mine again, and it seems ok. Very weird. Was using the same cable too (HTC one). Maybe it bugs out sometimes when it's next to my PC. Seems ok right now.

Anyone confirm this?
I've just bought 2 cables (cheap, retractable) from ebay for emergency use... :'(

Seen demo/display phone acting like that in best buy although phone wasn't flat but on sort of a stand and always on charge...

It has been discussed and confirmed earlier. It happens with cheap non-genuine chargers.
The solution is to use only the genuine charger.

I should add I do have a cheap charger and data cable from ebay that do work ok, so this problem is not universal across all non-HTC accessories.

Lol!
I only use genuine charger and battery no matter what but I hope the cheap cable would not cause this. It's just a cable anyway...
By the way, can you provide the link for the said discussion for my joy reading?
Thanks!

I had this the other day I was holding the phone and had it plug in the HTC charger. I was browsing the web and could not move up and down it just zoomed in or out like I had two fingers on-screen I restarted the phone but still did it I then unplugged it and it was ok.

Just some extra details here, the charger I was using in the video was a generic usb charger, but using the genuine charger doesn't stop the problem.
The screen is in perfect condition, not a single scratch, phone is less than two months old and I only have a genuine cable.
Also this happens on ANY hard surface, a book, tiles, wood, but soft things like wool or upholstery don't cause any problems.

Sounds like a proximity sensor issue.

I had this exact same problem as shown on the video on both the HD2 I had previously and the DHD. In both cases the culprit was not the cable but a cheap charger.

What the...never seen s.th. like this before...

Same **** here ;-(
Happens when using a eBay noname docking station! Phone is not laying on a surface! The last time i charged with this docking station there was no problem.
I will try the htc charger...

Slightly off topic but whilst my DHD is charging, if I run my fingers across the aluminum body it feels like its vibrating. I had this on my Hero too.
I'm almost positive its the current, as unplugging it stops the "vibration".

the erratic behavior of the DHD is caused by improper grounding, as the small current from the ungrounded charger is passed on to the phone's body, mostly by a other then HTC cable, there will be a current on the phone, small, but none the less there, as the digitizer measures the electric resistance against the screen on spots, as a human finger(flesh somewhat differs from nothing or non organic objects touching it) it measures a touch, this small current also can give a false touch, thus creating this erratic behavior.
hope this explains it clearly to you all.
so, if you properly ground the phone somehow, it will stop

A cable saved my Epic...

I just wanted to share my story so that others might learn from it. You will read in almost every thread about flashing via ODIN, one-click rooting, etc. that if you have any issues you should try a different cable. You might also read in various threads about how the stock Samsung cable is a piece of garbage, yada yada yada.
I heeded that advice long ago and replaced my Samsung cable with some quality and yet inexpensive cables from monoprice.com and went about my flashing/rooting way.
Flash forward a year. Gingerbread started leaking and after a long time of being on midNIGHT my flashing/rooting activities started to pick up again. After some initial success I noticed that my ODIN flashes started taking longer and longer and that the percentage of successful flashes was falling. I chalked it up to leaky Gingerbread.
It started getting worse and worse and at one point I thought I had bricked my Epic. That when I noticed that my cable was no longer attaching to the phone with that satisfying snap. It was easily sliding in and out. It had started doing this after I had inadvertently pulled the cable and the phone fell off the table. So I went and grabbed another cable, fired up ODEN and voila... ODEN raced through the flash like The Flash and I was up and running on the leak of the day.
So let that be a lesson to you. You may read "try another cable" over and over and store it in the back of your mind but never really know what the symptoms are that would lead you to know that it's time to do so. Hopefully my story may add some color to those simple instructions and maybe, just maybe you might save your Epic like I did!

I completely agree...but for some reason the stock cable hasn't failed me. Never. If you take good care of them, I don't see why not use them.

Stock cable never failed me either but I just received BB cable from amazon for 2.50 and the quality difference is very noticable.

The stock cable fails on my wife's epic but not mine. Same with her cable. I have since been using my old palm pre's cable and even it's wall charge adapter. It works for both of our phones.
I wonder if the reason is due partly to the cable and partly to the port itself.

Stock cable never failed me either, but I copped 3 BB cables in case **** happens!

Stock cable never failed me either and I flash a bit more than most. The funny thing is the cable that came with my Moto Finiti Bluetooth is twice as thick and fits much more snug. The stock cable works but they could have included a better quality one for a phone that was considered top tier at the time.

d'oh... wait thats not right either. damn auto correct gas a filthy mouth.

I wish we were allowed to thank multiple times. New cable is good cable. Thank you good cable. Dropbox and a good internet connection rarely fail me either, unless I'm rerooting.

I will have to admit that I was gonna call bs... because my phone has fallen off a ledge a few times. I attempted a ninja "catch a fly with chopsticks" as it plummeted to the ground, only to see a micro USB cable in my hand and an epic on the floor.

Blackberry cables are a bit too sturdy for this phone. I have 2 and recently I've had to revert to the Sammy cable because the bb cable won't maintain a snug connection. This happened to me and the phone constantly drops the connection if the wire is even budged a bit. Went back to the Sammy cable and all is good. Of cource I use the bb cable for flashing and just keep it really still lol

Same thing happened to me, could never odin my phone or use usb mass storage. Other cables would not work. So I went in and sprint gave me a new phone. It still wouldn't work untill sprint gave me a new samsung cable. It worked right away.

The OP speaks the truth. I can odin with the stock cable anymore so I've been using the one that cam with the gf's G2 and it works like a charm till I wear it out too.

My intent was not to disparage the Samsung cable. Mine was great for quite a while. I just wanted to let people know some symptoms that might point to a bad cable. I haven't tried the BlackBerry cables but the ones at monoprice.com fit well and work great. Until of course they fly across the room with the phone attached and get bent.

Woke up to a [possibly] bricked Atrix :(

Yup. Left phone on charger overnight - woke up and the camera was flashing every 2 seconds. That's all it will do. Whether it's hooked up, unhooked. As long as the battery's in that's what it does. No rom changes in over 2 weeks. No damage of any sort.... no recovery or anything

Well you can probably do a warranty exchange.
I voided my warranty and your mum.

I had something similar with my nexus one. Except it wasnt the camera but the trackball... changing kernels around seem to help a bit but eventually i took it for water damage. Take the battery out and let it dry off for a day or two. You can also try to pry it open and have your hand at any corrosion if you find any. However i wouldnt recommend that unless you know what yer doing.

I realize that but like i said i had the same experience and my phone didnt get noticably wet at any time could have been a single drop of water and corrosion takes a while to build up.
Still...
Im wondering if you used your original charger when this happend because i can personally say ive seen my atrix behaving strange when connected to some cheap random charger (touch screen not working for example). Didnt believe it could cause permenant damage though.

It was hooked up with a Blackberry charger, actually.
Still acts the same.

Check the charger to see if its power ratings are different than your otiginal one.
Also... does the device boot up in any way or is the screen simply black and the flash flickering no matter what?

Looking at it today, I noticed that the charger port (or inlet if you will) is very structurally loose. The voltage on the blackberry charger is about 3/5 that of the stock Atrix charger, if memory serves me - somebody at work switched out the chargers the day after I got the phone. It took a good 6 hours to charge...
ATT said that it would be full cost of phone, because it's personal damage.
I'm looking into the Mi-One.
EDIT: No, the screen will not even begin to come on. Camera flashing is the only indicator of any power. Used an external battery charger, and two different batteries.

The MI-One looks sweet!!!!

Moto will probably either fix it or send you another phone. I know people who bricked from trying to downgrade and they got another phone. I'm sure you could too. I would try that before you buy another phone.
ETA: Now that I think about it not being able to put the rom back to stock would probably be an issue if they can get it to turn on but if they can't they might replace it.

I also think you should bring it up with motorola. Waking up to find your phone bricked is hardly what id call personal damage. You also shouldn't bring up the charger issue. And as for the usb port i'd say it would take too much effort to discern the connection with that and the phone acting as it is, and im sure they would rather just send a replacement unit.
A usb port malfunctioning is hardly an account for personal damage. The usual case is they simply stop working, but definitely not brick your entire phone.

USB lead keeps falling out

I use my Note II as a modem and I'm getting really annoyed with the included USB lead falling out - it feels like looking at it too hard will cause it!
The curve of the bezel stops the lead fully engaging

happens to me too

I think it has been designed this way so that if you trip over it you are less likely to cause the note to fall off of a desk or wherever its sat.

Me too. The usb lead comes out very easily.
I thought at the begining it was broken but its good to know it is not just me...
I have problems connecting it to a philips desk clock and charger I have...

same here, I bought a charging dock on ebay (£6) so it's firmly connected when synching or copying data.
Don't know whether this is intentional or bad design, looking at the overall build quality though I believe it's the former.

I must have a weird note2. The cable fits snuggly and requires a small amount of force to remove it.
Admittedly I am not using the cable supplied with the note2 (I'm using the one that came with the GS3) so maybe it is the cable.

[Q] Changed flex cable for ear speaker..phone wont boot now

my ear speaker went out.. i ordered a new flex cable and replaced it.. checked all the connections 4 times took it apart put it back together.. when i press power.. green light comes on for 2-3 secs then nothing.. help.. im willing to send my atrix to someone to fix?.. give me some ideas please??

The first thought I had was your battery is dead.

Please check all your connections, especially the ribbon cable that has a jaw connector. This one is often the problem on this phone.

I've checked triple checked all the connections...when I press power it lights up green but no screen and I really can't tell if the phone is booting..phone worked perfect until I changed the flex cable out and nothing looks damaged..

Assuming that the entire device itself is off and that it's not just the screen, and that all the connectors are securely in place and not torn, the only thought that I can come up with is that this may be an ESD (electro-static discharge) issue.

Anyway to test that theory? Like test if the phone it self is still alive without screen coming on..the motherboard heats up a little like it's on but as far as I can tell none of cables are ripped

Connect the device to your computer with a data cable and see if it shows up as a device of some sort.
Of course if I was in that situation, I'd try other things too, like connecting the device to the charger with the battery removed, and see if it responds. I'd also try to get into recovery mode if possible. It's not likely to do anything different, but it's a better option than taking it apart again. However, I think it's either a damaged cable or an ESD issue.
