X1 optical joystick problem

Good day everyone
i'm using my X1 since about 2 weeks.
I recently did notice that after waking my phone up the "scrolling down action" is performed...so the optical joystick thinks i'm moving downwards but in fact i'm not even touching it...it not only happens after waking it up, but also when i want to scroll upwards it happens often that it's sliding downwards again when i release the touchy surface...
cleaning of the touchy surface didn't help...aswell as adjusting the sensitivity of the optical joystick...
does anyone else have that problem...or anyone out there having an idea how to fix?

mine dont have that problem at all and if hardreset dont change it i would
write it off as a hardware malfunction

Some solution?
The does same thing happen to me?

I had this problem before too. Somehow, while i was at school, i must have shaken it a lot or something, because i had P.E. that day. When i got home after i had p.e., the joystick scrolling problem stopped. I had the X1 in my pocket the whole day, so i guess when i was running in P.E., something must have shaken and the problem is now fixed.

This has happened to me only once, while browsing. It fixed itself after a soft reset. Very weird.

Solution!!!
Mine had a very similar problem. It was making calls alone once something just touched the joystick's surface. I took it to a repairing center (with a little hope once i read above comments). However they repair it, well, at least the joystick is working on its scroll funtion but when I press it nothing happends. They told me that it was repaired by just cleaningl, with paint thinner and a gum eraser, the part that is marked inside of the red circle in the image below.

Mine's got that problem too.. It was so annoying that I disabled the optical joystick thingy... Don't need it anyway

Im glad i dont use that optical thingy. Its annoying when you want to press center button on D-pad but then accidentally scrolls up or down.

Sorry for poping in this post again after er.. i think this is like a year old post. I just had this problem last month.. or maybe months. I been ignoring it for some time now but well it is getting annoying (It always make the speaker go louder for some odd reason by scrolling up or while searching for a contact it scrolls up). I have never used the d-pad and thought of disabling it but not sure how too.
No more warranty as I bought it for some time already (They said so), I send it back to the shop and they wanted to charge me MYR200 to change the ribbon. After thinking a while that d-pad only cost like $7.99USD which is MYR25.10 from cnn.cn website.
Do they mean the slider flex cable which cost MYR147.619 (After converted)?
Does that has any relation with my D-pad getting stuck at the up button?

[Q] wonky flash + non working ambient sensor after power button service

Hello,
Recently I sent my nexus one for a button replacement. I got the phone back with some strange symptoms:
- Flash light blink at random event (first boot, after I hang up a call, etc..) but cannot be controlled by software (torch and camera app in CM7, MIUI or the stock firmware). The camera however works fine.
- The ambient sensor is dead. It either reports a very high value (2600 or 5800) or a very low one (10) (these values were taken from the CM7 auto brightness adjustment settings)
- Mic from the headphone when I plug in does not work anymore (the mic works before and tested to be in working condition)
From some online research, it seems like a loose connector can cause the wonky flash light problem (report by fblodroid, he fixed it by plug the connector back)
http://www.google.com/support/forum/p/Google+Mobile/thread?tid=46ef1e3a49030ed9&hl=en
My question is: can the other two problems be related to this connectors as well? Or did I get a defective board?
I plan to fix it once the tools arrives (dealextreme takes forever!). Another option is to bring it back to the service center to get fixed (this will take a week, and who knows what kind of fees on top of that). I'd prefer to fix it if I can.
Anyone has some knowledge about this kind of issue? Any idea what do those connectors do?

Dude, if your N1 is on warranty I wouldn't even bother to think what is causing this problems Send it back. You'd have o wait some time but you will still have your warranty for the future, and if you disassemble it you will probably loose it (not mentioning that your problem could be unfixable!).
They screwed up and they should fix it for free. I hate when electronics come back in worse condition after repair than before...

Well, it's out of warranty. But I think I have 3 months part warranty from the last repair.
They didn't put any seal on the screws this time. Maybe you're right, it's smarter to just send it back to get everything resolved.
I'm just curious whether all the problem described above can be attributed to the board they replaced (or one or two loose connectors).

I didn't know about the warranty, BUT: They spoiled your phone while fixing button so as a consumer you have right to demand that they fix it free of charge! Maybe it's something like silicon defect or "cold solder" (don't now if it's correct name. Google-Translated it) on the main board. They should have tried it before sending it to you.
Wish your N1 will get better soon

[Q] Can I recover this LG G2 ? Snow on screen(see pic)

I got this phone the other day, It's just got snow all over the screen (it's out of warranty) so I opened the cover, pulled off all connectors and re-seated them (didn't remove any boards, just what was accessible once the back covers were off.
I am new to Android but, this model I have replaced 2 Displays on (not this phone), seems I get one for cheap with a broken display, I fix it and someone offers me more than triple what I paid for, so I keep selling them :-/ (a man cant turn down a big profit). So I know how to pull this phone apart and replace parts if needed. I was looking to give Android a solid shot here (I am a Windows Phone person now)and not sell this one...
Not sure if the display is toast or this is just a Bricked or something else.
Note:
-If I connect to a PC, it connects fine
-When the phone is on, If I touch the lower of the screen, I hear clicking
-Double click on the center of the screen wakes up the display.
-Verzion software tool does not detect the phone (even though a drive is mapped for it)
Also to know, I have never rooted a Android device, so no idea on how to tell if it's rooted or not from the file system. Yea, when it comes to Android devices, I am a NooB.
Any idea ?
Thanks in advance !

Ok, Still trying to trouble shoot this, figuring it was a Brick or something with a lot of effort (The touch screen seems to work but, power off was a guessing game where to push to get it into bootloader mode).
I tried to go back to Stock with it, following these directions...
http://forum.xda-developers.com/showthread.php?t=2448960
Now during the process, every once an a while, on the top of the screen, I can see about 1/2 of the ICONs, it's static so it does not update but, it's the most I have seen off this display.
After showing Successful, it's still doing the same thing. accept a hair of it, static across the top of the screen.
So, does this lead down to a hardware based issue (if so, what part should be replaced), or is this display damaged and needs a replacement ?
Has anyone gone through this and can help ?
Edit, Picked up the one of the cables for the phone that the video, power, headphones all plug into, as all my problems are resulting in something that plugs into this cable, figured I would give it a shot, The only things that are left are the Main board, or the display itself.
Maybe this will fix it ?

[Q] Ghost touches; bad grounding; static charge

Hello,
I've been having problems with the touchscreen lately. Everytime it is not 'grounded' via my PC USB cable, whenever I try to put two fingers horizontally or vertically they seems to disrupt each other ie:
http://i.imgur.com/ASwFmhw.jpg
This doesn't happen when:
1. USB connected to the PC. (seems to have the best result)
2. I hold the phone with my hands and it doesn't lie on a flat surface. (still ghost touches when I align 3 or more fingers in certain position)
3. It is hooked to a decent charger with proper grounding.
Seems like there is some kind of static charge leftovers or something that disrupts the multitouch in horizontal and vertical positions. Any way to permanently get rid of such static electricity? Or is it literally 'leaking' somewhere from within the device and the only thing I can do is RMA?
People on the MIUI forums reported similar problems but only while charing the device with improper chargers.

if You have root try adding persist.usb.hvdcp.detect=true to build.prop, always take a backup before changing anything, see if that helps

Tried, didn't work. The issues seems hardware based. The grounding of static electricity is simply broken inside the phone and there is no way to fix it other than to disassemble and see what is wrong.
Thanks anyway.

Damn that's bad, I've solved with this line, hope You find the problem but as You point it seems like a defective touch panel :good:

I also have ghost touchs while charging AC. I've tried a lot of roms and anyone solved it. Anyway, I learned I shouldn't use the pone while charging xDD

That's just a bad filtered charger, I own a 2A charger which is bad filtered, i hear the mains hum in my earbuds when connected to the phone while charging with this one, ghost touches and random taps included.
And then I have another 2 chargers, one is 1A, which came with my MI3 and the other one is a 750mA Nokia AC-20E which came with Lumia 520. None of these two make ghost touches or hum from mains. All depends on their filtration circuit quality. Try some other charger, for instance some Samsung charger and see if the phone is usable then.

The left one is the 2A "ghost touch" charger and the right one is the original charger which came with my Mi3.

I RMA'd the phone, the technician stated that a change of the touch panel was done.
Alas, the problem persists. I specifically said that there is a grounding problem yet they only service the touch panel. I am quite furious right now.
Waited almost a month for them to do exactly nothing with it.

I too hv this issue why is it anyone knws or hv solution for it?

i m facing this problem even when phone is not connected to usb...and when i restart it problem solved for some time and then again continues ...any solutions found ? one plus one also got this problem

N910T won't fix on satellites, even though it can see them.

Hey guys, I'm pulling my hairs out on this problem I am getting with my note 4.
Long story short - I cannot get a GPS fix (to even a single sat) with my N910T.
The longer version:
This thing had a cracked screen - but worked great before that (no GPS problems) and I used it a good year before breaking it. So I bought a N910A (ATT) note 4 to use the screen to fix my trusty note.
I gutted both phones, and put my N910T motherboard in the N910A's frame, with the screen still attached to the frame. I kept the N910A's USB daughterboard (with the charging port) because in the research I did, it seemed basically identical to the one from my broken screen frame, and I knew it would be tricky to get that out and into the new one without busting the new glass or destroying the flex cables.
So after some trouble with the S pen not working initially (the cable didn't press in fully, had to stick paper behind the flex cable and it went in properly) I was able to get the phone up and running again, and all features seemed to work great again.
However - I noticed after a couple days that the GPS was super spotty, so bad it was mostly unusable. I noticed that AGPS was on and it was using wifi and mobile data to help get a fix, so I turned it to GPS only mode. In GPS only mode the phone gets not signal whatsoever, no matter where I am.
I tried the simple fixes many recommend online, one which is to try tightening the screws a bit, and in fact, as this process continued I opened and closed up the phone several times, making sure to carefully but tightly screw all the screws back into place. That didn't help. I also tried making sure the compass calibration was good - and it made no difference. And I even factory reset to make sure there were no issues with installed apps or anything like that.
I got to thinking, perhaps its a issue with the small bendable pins that press from the motherboard into the mid-frame not making good contact, so I tore the phone down a couple more times, slightly bent out - very carefully - all the pins that press into the mid-frame to make them all have a solid contact, and even tried to get any corrosion or debris from the pads on the mid-frame. I even made sure there was contact for those little ones alone the sides of the phone which seem to have something to do with the buttons rather than what I'm dealing with.
Still no luck, so I tried doing a NV rebuild, which I read might solve getting 0 sat fixes, and discovered my phone wouldn't let me into that menu of the service options, so I had to install root and then do it through shortcut master instead. Once I finally was able to get to the menu and run the NV rebuild.... nothing changed.
So I am fresh outta ideas, and I'm thinking that A) that ATT USB daughterboard actually plays a part in GPS somehow and I need to take my TMO one out of the old phone and put it in the new frame and screen.... or B) Something is damaged on my motherboard.... or C) Somebody out there has a better solution
Any ideas, experiences of what worked are all appreciated!

BUMP --------
Still having this issue. Tried opening it up, and realllllly making sure those antenna springs are making contact, and I made sure the contacts on the mid frame are clean.
I tried TopNTP and that made no difference. Here is an image of whats going on when I run GPS Test:

Bump?
Losing hope for my old phone here

Anybody happen to know if the daughter board that has the USB charging port plays any role in gps?
