capacitive button problem - Nexus S Q&A, Help & Troubleshooting

Recently my phone has started randomly opening up the Google now page by hitting the magnifying glass by itself. It happens often, is this a software problem or is my capacitive button broken?

I saw that someone fixed it by loosening or tightening the screws under the battery cover. I can't find that post though

Hmm, Iv never opened up the phones screws before. There are 2 screens near the bottom that i guess holds the screen and back of the phone together. Loosening these would fix the problem perhaps?

[Q] Screen appears loose in the top left corner of Nexus S

Hi,
I've had my Nexus S for less than 4 weeks, and I just noticed today that the top right corner of the screen seems to have some give when you press on it. It apparently just started happening now... Anyone else have this issue with their phone? I'm wondering if I should just run to Best Buy and have them exchange the phone for me before it's too late...
Thanks,
Mike
I don't have that problem with mine but in your case looks like you might have to take that trip to best buy

if you look at it, does the surface of the top corner part raised a bit compared to the other corners or sides?
I ask because I tried to press gently on the corners and also the sides and there's a very slight give. It maybe because of the type of screen (plastic?) causing the give when pressed?
yeah it appears to be ever so slighlty raised, and has a very slight give...
any word on if this is normal? I have the same issue with the bottom capacitive side....it is noticeably lose sometimes, I can push it then it becomes tight...then the capacitive buttons wont work unless I turn off the screen then turn it back on.
My 2 week old Nexus S just started doing this. It feels like the screen is attached with glue and the screen has separated from the frame. I can press on it and it sticks for a moment, but if press a minute later it clicks again.
My phone had the same problem.. Upper right screen was lifting ever so slightly. I was passed my thirty days so i couldn't bring it back to bestbuy. My only option was to send it to samsung for repair. The problem was that they had it for almost three weeks and when i got it back the screen was still lifting up. I had to send it back out and almost three weeks later (again) i got it back and it was fixed. They ended up replacing the PBA. Not exactly sure what that is but the phone is fixed.

Anyone replace a digitizer on a sensation yet?

Cracked my digitizer and the new one is supposed to be here this afternoon. Anyone done this yet? Anyone found a good breakdown guide?
How did you go? I'm about to tackle it tonight!
Here's a video

I have replaced it but with a terrible unresponsiveness that still exists for a short period of time after screen activation. The process is a bit in depth, though.
You need to rip up the phone from the back to the front. torx screws in the back come out, the plastic battery tray comes off, two circuit cards come off, unplugging the ribbon cables. The rest of it is a very gentle prying to get the double sided sticky tape separated from the digitizer and remaining case. you will need fresh tape to lay down so it gets a good seal, and I recommend latex gloves to keep fingerprints out. Dust free environment/do it in a plastic bag as well. Kind of a pain to keep the digitizer and LCD free of debris. I am still trying to figure out what the hell is causing the screen unresponsiveness... maybe a grounding issue.
So I received my new digitizer, and it is broken already - I slid the ribbon between the chassis and LCD the wrong way, and in trying to pull the ribbon back out, it snapped so my Sensation remains in pieces while I get a new digitizer. Also bought a roll of 2mm 3M tape to seal the digitizer back too!
The disassembly isn't complicated, but it is fairly involved with lots of delicate ribbons.
What sort of unresponsiveness are you referring - is it always, or just when it's on charge?
The phone is almost completely unresponsive immediately after reactivating the screen. This could be after it disables the screen via proximity sensor for a phone call, or securing it and trying to use the lockscreen. After swiping my finger across it for several seconds it works perfectly, however. Either seems like a software recognition or a grounding issue, as I'd imagine the finger swiping is slowly building a charge. At least that's my theory so far.

How did you go with your theory? I just replaced the screen in mine and I am having issues with my sensitivity when the screen first turns on, too
I replaced the digitizer twice so far. Both are unbranded "HTC" labels, my original said HTC and T-Mobile in the right. Also different serial. Same unresponsiveness as well. It has to be something else.

So do you think it's the digitizer itself?
Its either the wrong digitizer for the model of phone (Europe/USA/fake garbage) or something else is at fault. Le sigh.

Yeah, I have been reading and some other people have had similar problems. I asked the seller of the digitizer and they said they have not had any problems like this before.
I think I'm going to sell the phone soon, will buy an HTC Desire or Desire HD for a few months until the Sensation XE comes out.
I also want to sell this phone. In its current state I can't see it fetching more than $100 though... Half the purpose of a phone is quick reference, not a 10 second frustrating unlock frenzy.

Fairly unrelated, but do you thing my phone is in need of a new digitizer or an LCD? Everything works fine, except for those 3-4 cracks that don't look so great.

Yeah, you can't exactly answer incoming phone calls
I'm wondering if it might fetch more, if I put the cracked digitizer back on there.

Yeah, that's a digitizer crack. I wouldn't bother replacing it...
I just replaced my digitizer and I'm getting the exact same behaviour. A phone shop also tried two of their panels and they also exhibits the response issue! However reinstalling the broken original digitizer works!
How can all three panels I've tried be faulty? It must be something else.
I can answer calls but I have to swipe rapidly across the answer key. It sucks and if replacing the original makes it work then its a model number issue. Probably the wrong digitizer for that phone revision.

I repair cell phones for a living and have done the sensation digitizer twice. I now turn them all away.
from what I have been able to deduce, something about the space between the digi and lcd causes the unresponsiveness. try using a little more adesive, maybe a layer on a layer, it may work a little bit better

Thanks, I'll give it a go, I suppose!
Have you determined that it is more space that makes it better?
A bit of Googling suggests that many struggle with the unresponsiveness, but I suspect that there might be two separate causes here. Some report pretty random unresposiveness, and it helps to restart the phone, and apparently fixing a bad ground connection between the phone and the back cover fixes the problem. Then there are many who report that it has happened after replacing the digitiser.
I've just replaced mine, and every time after the LCD is activated, the screen is very unresponsive for 15-20 seconds, and then everything is just fine as long as the LCD remains on. Is this exactly the same behaviour everybody else here has seen after replacing the digitiser? The most irritating bit is that it makes it hard to answer a phone call in time.
I disassembled my phone once more and put it together again making absolutely sure that it was done properly. No change. I haven't glued the digitiser properly yet, though, since I'd like to get confirmed that it's working before I do something which is hard to undo. But I've tried different spacings between the LCD and the digitiser (though this is a bit difficult when the whole thing is partly loose), and I haven't really noticed much difference. I've kept much of the original glue, which isn't very sticky anymore, which means that I probably have a bit of spacing already. Any chance that the responsiveness gets better with as little spacing as possible, has anyone tried that?
Please keep posting reports on both what doesn't help and on what seems to improve the situation.
I wonder if it's like the iPhone 4. Many people complained about the proximity sensor not working anymore once the digitizer was replaced. Either way, I think I'm going to suffer through a couple months of this and buy a new ice cream sandwich phone when they come out. :/

[Q] Replacement Digitizer Problem

So I finally replaced my cracked screen and I've been having issues with my new digitizer. It's one of the LG digitizers, not the ones that say T-Mobile at the top. When you touch the extreme left side of the screen, it acts like you're touching the extreme right side of the screen at the same time. It's very weird - when I try to capitalize, it also backspaces, and my a's all have l's after them - stuff like that. It's like that all the way from the top of the screen to the bottom.
I got in there and cleaned a couple of specks of dust that I had accidentally left between the digitizer and LCD screen and it didn't seem to help. I used compressed air to clean the contact where the digitizer ribbon cable connects to the motherboard and tried to get the ribbon cable itself to sit under the motherboard nice and straight (I had a little trouble with it the first time and it could have been crooked, I guess, but I'm not sure if that would even matter.) I've also tried soft reboots, removing the battery, full wipes, and even have experimented with a few different ROMs. Acts exactly the same.
What do you guys think? Do I have a bad digitizer or is there something else I could try to get it to work properly? Thanks!
I buy broken phones of Craigslist and fix them. I have put digitizers on 4 g2x as of yet never had that problem. I'd make sure the connections were nice clean and seated correctly. I see you've done that so my conclusion is that you have a faulty unit. Run a calibration app and see if that helps

I had bought a digitizer with the LG logo on it and it was not as senseative to the touch and as well when touching the left or right sides of it where off a little. I used the ones with the T Moble logo and all works like new.

Hi, my screen cracked, so I got a replacement digitizer and installed it. When I reassembled the phone, it worked fine, except the buttons at the bottom (home, back, etc.) and the bottom 15% of the touch screen do not register. The rest of the touch screen works fine.
Do you know if that part is connected differently from the rest of the phone? Or any other reason it might be broken.
This may be dumb on my part, but my package didn't come with adhesive, so I used superglue. Could that be messing up the sensor somewhere? Or is it not likely that?
Any thoughts/comments would be greatly appreciated.
You probably got some glue in the wrong place. I used 3M double sided adhesive, that way I could be exact with the placement

Hah what he said.
You should never use glue of any sort on electronics. If the manufacturers don't do it, then you surely shouldn't.

Repair Volume Up (Damaged Button)

Does anyone have a quick fix solution, to repair a damaged volume up (replace little aluminum button), without replacing the entire main flex cable? The little aluminum button was damaged, and no longer flexes to contact the PCB. Volume down still works properly. I've searched and the only solution I've seen is replacement of the main ribbon. Please help.
P.S. - I attached an image of the button I'm describing.
Last image did not show up. Hope this one works.
Common problem with the inspire. You have to replace the whole thing including cable that goes to main board. Just about the whole phone has to be disassembled and the new part put in. I know the actual part is pretty cheap. Not a simple task though and no quick fix.

So the dome is cracked in half? Looks like it. One suggestion, maybe try some solder to "fuse the dome back together, maybe just maybe... Otherwise I use flex circuits at my work and I have some of those domes but they are bigger. I could send you some and maybe you could trim it?
One thing I just fixed on my Inspire, the down button wasn't working real well. The domes were fine just had to press real hard. I put a little, thin piece of paper (backing from a sticker) between the little foamy like piece and the flex circuit so the button doesn't move as much when pressed. Worked a charm!
Maybe that will help out others.
If you're unfamiliar, as i was, start at 2:23 on this video and you can how to get the buttons out. Can't post links yet so here's the video title.
HTC Desire HD Disassembly Video
Hi ive just repaired my volume flex cable(tore it during digitizer replace) and my volume down button still won't work! After further investigation I noticed that inside the actual housing where the volume button lies there are "painted metal contacts" similar to the ones located on the GPS,simcard cover, and wifi antenna/battery door. I've tried a very small piece of foil with no success, is there some kind of conductive paint for small electronics?

Sensors still work for me
When I was removing the battery to stop a rom that did not work the button or knockers snapped in half. The sensors still work if I reach in there with my nail and I was hoping that there would be a small replacement for these buttons, but I wanted to check here first to make sure that it would not break the sensors and then I would have no way of running AAHK or going into recovery.

[Q] Screen Clicks

When I push on the screen directly to the left of the power button, the screen clicks as I release the pressure - as if there is glue that is unsticking itself. This also happens all the way on the other side (left) of the screen parallel to the power button. It's minor, but annoying when you pay full retail for a phone.
Does anyone else have this "problem"?
I don't want to take it to Verizon to have them send me a sketchy CLNR or possibly not consider it a problem and do nothing.
Would tightening the two torx screws on the bottom possibly fix it?
Take it back

If it's the RAZR HD then take it back. That's the most durable, solid phone I've ever had in my hands. It must be defective.
I can't take it back, I've had it since December. I'll get a return and my experience with those when I had a Droid RAZR Maxx was far from acceptable

So I got fed up with the quiet clicking and opened the phone up...underneath the screen are prongs that support the weight of the screen. By pulling the prongs down a few millimeters I have eliminated the clicking noise. I figured I would put a solution up here if anyone gets easily annoyed by build-issues like me.
