Cube u9gt2 screen problem when chaging possible fix! - Miscellaneous Android Development

It has been really annoying me not been able to use my cube when plugged in due to the screen going crazy with thing like entering multiple key presses on the keyboard, and the touch not working properly.
When I looked at where you plug in the charger tip into the tablet and noticed that it touches the aluminium case of the tabet' so what I did VERY CAREFULLY was to use a drill bit slightly bigger than the hole for the charger and drilled out a few mm to make the hole larger, make sure the drill but does not have an extended point or it will drill off the tip where you charger plugged in.
Up to now I am using it plugged in and writing this with none of the previous problems.
If you want to try it please be very carefull and drill at a very low speed and only a few mm of the case

Faulty N1 Dock?

I just got a nexus one dock delivered this morning... but nothing happens when I put my phone in.
I had the desire rom so I flashed cynogen and tried and still nothing.
I am guessing its faulty but there isn't anyway for me to actually be sure is there?
I guess I will just have to contact HTC support and get it replaced!

When your drop it into the dock, does it show charging? You could just have a set of dirty contacts - a quick swipe with a pencil eraser is an easy way to make sure they're clean.
Are you running a N1 ROM now (Stock, Cyan, Enmother, MCR)? If so, dock it and head to settings and there should be a "dock" option there now once you've docked.
Thanks for telling me to try that.
I can't figure out what the problem is. I did get it to work by pushing the USB wire into the dock and plug connector.
That makes me think that the USB wire is damaged but it seems to not require any pressure to work fine on my HD2 (as its the same connector) so I am a bit stumped by this!

Are you using the wall charger or USB charger? If it's the USB charger give it a shot with the wall charger. They say don't use the USB charger and the only reason I can think of is that the USB charger only provides .5A and that may not be enough to power the dock and charge at an acceptable voltage.
I am using the wall charger now but I am UK based so I am not using the suplied charger - rather my HD2 wall adapator and USB cable although that shouldn't effect how it works clearly.
I do wonder if the invisible shield may be causing part of the problem.
It doesn't "slide" into the dock I have to push it even though the bottom part of the phone has no protector (as I removed the shield from there) it does seem to be super temperamental to the EXACT angle and position I have it in the dock...

As long as it's pushing 1V I don't see why there'd be any problem if it's not the "supplied" charger.
Can you tell if the phone is making good contact on the bottom? You should be able to see the pins actually depress and "disappear" as the phone pushes them down into the dock.
which dock have you got
I'd have thought the problem would be the skin blocking the three contacts ( is it a genuine dock?

with the invisible skin I need to push the phone in a little as well. The skin makes the phone not fit as well so that may be your issue, not the dock.

^^^^This^^^^
I removed the protector totally and it still requires pushing into the dock and then it seems to randomly disconnect the charging for no reason after a couple of seconds.
It must be that the dock is faulty (of course it could be my phone but I can't test that out so I will assume it is the dock).
I e-mailed HTC who said if I phone them they will sort out a replacement.
They seem quite efficient so far although I haven't phoned them yet!
I have to be honest I am not impressed with the dock... sure it looks nice and the bluetooth streaming is cool but even if mine worked perfectly and charged the phone - the phone slips out if I touch it anywhere - it must be the most unsafe dock ever. Forget using the phone in the dock. It won't stay in it if you press it....

USB connection, wear and tear

So after so many flashes of custom roms, kernels, modem, and etc.
Are you guys finding it harder for the micro-usb connector to actually get a tight fit into the phone? Mine's so loose that the slightest tug or movement will disconnect it from powering or connecting to my PC.
I slighlty fixed it with needle nose pliers , a more efficient fix anyone?
Im having the same issue

Definitely noticed this too. I notice my usb cord after a minute of being plugged looks like it's coming out a little.
I actually don't have this issue. I don't know how much you guys flash but I am doing something daily beyond just charging. I don't move my phone around much when it is plugged in.
On my phone, thin plastic piece around the usb port is cracked and i sometimes confuse that with the sliding usb door and tries to close it until i looked down to notice that it's not the door that i'm trying to close
I've noticed this recently too (I've had mine since July). On mine, when holding the phone normally, if I push the cable toward the center of the phone and it comes loose. If I push it outward (toward the volume buttons), it doesn't really move.
If I open the usb door all the way, plug the cable in, then close the door *slightly*, it holds the cable a lot better. Not like it did when it was new though.
Has anyone diagnosed the cause of this yet?

What exactly did you do? I was a little hesitant to try bend anything - I didn't want to make things worse.

Actually I do not recommend doing it this way until other means are available, remember, ruin your usb connection = your screwed.
But it's the sides of the usb connection I'm trying to tighten up. Where it forms / \
Mines so loose, that if I do a simple reboot and move the wires too much it will give me the: ! to android guy pic.
If it's becoming loose its due to the plastic bezel around mini usb port. Eventually it will crack at where the door hinge has to pass through the part just before the door becomes secure when set to open position. Not sure if it's a plastic quality problem with a certain batch just order a replacement.
Secondly the usb cord supplied is not flexible at the handle for the miniusb connector. Flex it to much you will dislodge the data + - wires. Took it apart and inspected. You'll need to resolder to fix it.

Thanks for that post
I have a question though: When you say order a replacement, do you mean a new phone or the little plastic bay that holds the charger?
I also bought this phone at launch, and I'm sure that means I am out of any kind of warranty.
UNLESS!
Is there a year warranty on hardware defects?
You're still under warranty (1 year). You'll have to deal with a AT&T DSC for replacement.

So does that mean I should back up with Titanium Backup and flash back to stock?
cracks
My cappy has 2 tiny cracks on the top of it. One where you posted ( between the charging port and the back of the phone ) and another between the headphone jack and the back of the phone. They are so small no one would notice them unless looking. Returning the phone would be too much of a hassle for me ( I'm lazy ).
My idea was if the plastic began to chip or crack anywhere else I would just buy a bodyglove case and voila - no more cracks. And I didn't have to talk with an AT&Tard to fix it.

If you actually have physical damage to your USB port to warrant a replacement phone, yes...I'd say flash back to stock.
If you're trying to address any problems you have with the USB slider door, I doubt they'll replace your phone. You'll probably have to have it sent in to Samsung for repair, and shipped back to you. Of course if your phone goes to Samsung, you had better flash stock.

It's not the slider door. That is broken now too, but it isn't a problem for me. It is the USB cord won't stay in the charing port anymore. It is a bit of a hassle to wake up in the morning and my phone didn't charge.
For each usb wire that I use, I am now gently crimping the top and bottom of the usb connector to get a tighter fit. DO THIS AT YOUR OWN RISK THOUGH
It seemed to help me to get a tighter fit and now I don't have to check if the sucker is charging or not.
But yea, I was at the point where it would not charge my phone if I did not get it right, sucks I know.

^^^I also did that and it helps^^^
And, on the usb wires I use, there are little prongs, or tabs, that I gently pulled up with a tiny flathead screwdriver, actually a clean razor blade worked better... But I pulled those tabs up, and now I have a pretty snug fit.
And of course, do that at your own risk.
I started having this issue too where the lightest touch on the sides would bump it loose from the connector. In my case though I noticed that I did not have the door open completely all the way (yeah DUH). Once I pushed it completely open it fit much better.

I have flashed a lot and my phone is repeatedly connected and disconnected from USB at my desk all day at work and my usb still fits snug. But about 2 weeks ago the little plastic sliding door started sticking as I was opening and closing it and yesterday it finally just fell out of my cappy. Bought on release day last July.
I had this problem too, but it was the cable, not the phone.
Got a new OEM cable off of Amazon, and now it's nice and snug. Maybe not 100% like new, but pretty close.
Because of the little metal hooks on them, Micro USB cables tend to wear out much faster than the Mini USB cables of old.
I swapped mine out last week for another refurb (number two) because of this. It got to the point that I had to make sure the cable was in precisely the right spot otherwise out wouldn't charge.

USB replacement

Hey everyone,
Since we all hate the stock supplied nexus 5 cable in some way I'm sure we all seek out other alternatives.
I switched to the USB cable from my nexus 7 as it doesn't wiggle around while plugged in and generally fits better than the stock cable.
However I've noticed that it is leaving very faint grooves in the soft touch plastic part of my usb port opening, right where the two top "teeth" are.
Has anyone found a USB that doesn't leave any physical marks on the phone or is it just something we have to live with?
Any input is appreciated

For me the stock cable works nicely. I however noticed that it was getting weak by the computer attachment.
that happens when we turn it 90 degrees angle. I'm using this as of now ans is very strong. http://www.amazon.com/Mediabridge-2...55&sr=8-4&keywords=high+speed+micro+usb+cable

[Q] replaced digitizer now screen is not working

hi,
I might be posting this again so sorry for that and bad grammar if any.
I replaced digitizer on my pad and now screen is not working . i hear notification sounds coming up so i am sure that its switched on. but nothing is on the screen. and also the indication light wihich turns green when charging is also working. i am able to access internal memory fwhen connected to pc so i think everything is okay inside.
thanks
Check the following after you pull the back case of the unit and then flick the main board power rocker switch to the off position:
- the LCD connector that runs across the battery - make sure that both ends of it are plugged in and make sure they are both snug. Re-seat the connectors. Make sure there are no broken pins on both sides in both the male and female parts of both connectors. Also make sure that you did not kill one of the connector wires.
You may have broken your screen when pulling it off the digitizer. One strong pull or twist too many or too much heat from the heat gun can do that.
Check that you have put the ribbon connectors in properly.. I just did one late at night and found that had not locked them in right.. Also check you have the right parts as it seems there were different variations being sold

MicroUSB connector malfunction on Z5 (bad contact? liquid electrical cleaner?)

Hi all,
It's been two years I have been using my Z5 Compact, and the MicroUSB connector is hardly usable now.
I of course tried several cables.
It is very difficult to charge the telephone. I don't know exactly what the problem is. I tried cleaning with a dry air bomb (for keyboards etc.), but to no avail. Seems like a bad contact.
Is it possible to use electrical parts liquid cleaner to properly clean the USB contacts?
Anybody having the same experience?
MF
I had the same problem, usb cable didn't fit in entirely.
Culprit was a piece from the inside of my jeans pocket was pushed deep inside my usb port. It was pretty much stuck in there but once I got it out the problems where solved and I switched to magnetic usb cable to prevent this.
I got it out using very tiny pliers and a magnifying loupe.
Hope this helps..
Regards
Mine is going to die sometime, soon, too! i already bought a new one on ebay, laying ready to be installed here! In a couple of days i´ll take a hair dryer and then i´ll peel of the back cover and replace that broken connector
update: 17th of june!
Just wanted to tell you guys, it worked! I just replaced the USB Connector with the one i bought on Ebay, price was around 4 Euro or so, not much i think
It was rather easy, as i already own the needed tools (a very very small philips screw driver, and a tool to go underneath the back cover and a hairdryer)
took about 20 minutes or less!
Just use the hairddryer to heat up the back cover, then use the special tool (or a thin knife?) to loose the back cover and peel it off
then you have to remove 2 screws on the lower part, then you can remove some sort of a "bar" over the usb connector! next you have to lift the "motherboard" on the lower part (yes it moves down to the usb connector) but first disconnect the usb connector! then pull out the broken usb, shove the new one in and do all the above in reverse order!
