[Q] Nexus 5 screen swap - replacement digitizer won't recognize touch - Nexus 5 Q&A, Help & Troubleshooting

I purchased this replacement Screen/Digitizer/Frame assembly for the Nexus 5 after dropping my phone and cracking the glass front. While the glass was cracked, the digitizer and screen work fine and I can use the phone as-is apart from the shards of broken glass all over the touch surface.
When I received the part, I disassembled my phone (with much help from this guide), swapped over the parts to the new housing, hooked everything up, and the digitizer doesn't recognize any touches on the screen. I went around a couple cycles of swapping parts back into my broken phone and everything works like it should. Swap back, no touch.
I figured this must just be a defective unit, so I returned the parts and ordered another. I swapped everything into the new frame and I get the same result - screen works, digitizer doesn't.
I'm willing to accept that I'm doing something terribly wrong here. What troubles me is that every time I switch back to my existing phone screen, everything works like it should. If I was somehow plugging things in wrong or assembling the unit incorrectly I'd expect that it would apply to my existing screen too. At this point I've disassembled my phone, swapped the innards to the replacement screen, then swapped everything back 5 or 6 times now. Each time I do this, my existing screen works and the replacement screen won't register touch. As such, I find it hard to believe that I'm just assembling things wrong because somehow it works every time I put the old parts in, but never works with the new screen.
Does anyone here have any experience with screen swaps? The whole thing is really a straightforward procedure and there's not much to goof up that I can see. Does it even seem possible I could have received 2 screen assemblies with non-working digitizers?

Judging by the reviews, stay away
Looks non-oem as well lol

Most of the negative reviews there look to be fit issues. There are a number of little adhesive pads and rubbery bits that need to transfer over from the existing frame, and I strongly suspect that the people complaining about light leaks or fit issues probably didn't notice that the replacement part didn't include all those bits. None of the reviews that I read mention any problem with touch not working.

Exchange

I sent the vendor an email similar to my OP to see what they say, but I paid extra to get the Amazon Prime vendor on this part so returning it (again) should be no problem. I'll give them a chance to figure this out, but if not, maybe third time's a charm?

[Q] Anyone have much experience with failing digitizers?

So I guess I should start with the background info...
I have a MT4GS that I picked up off eBay with a broken digitizer. I replaced the digitizer right away with minimal issues. Once the phone was up and working I discovered that the earphone speaker wasn't working. I purchased a replacement speaker, but that too failed to work. I've used it for several months, making do by using speakerphone mode when I had to make a call. But that's really annoying.
Yesterday I finally had the time to pull the phone back apart and take a look at it. What I found was that the old speaker had been soldered to the board, but the leads had broken off. I scrapped off some of the protective coating on the electrical traces and soldered the original speaker back in place. I had an issue with the black coating that surrounds the LCD, it took several tries before I had everything back in place. But at least when I started the phone back up everything looked good and a test call confirmed that the earpiece speaker worked. (Yay!)
And then last night when I went to play a game, I noticed that the touchscreen seemed off. I quickly downloaded a couple of drawing games and confirmed that the digitizer wasn't working right. I also picked up Z-Device Test and found there are a couple of holes where the digitizer fails to register a touch and several more places where touch registers but weakly.
Are there any thoughts on or experience with digitizer issues?
I don't know if it will help the problem you're having but it WILL tweak the sensitivity some for you. It's probably well worth a try......

So I pulled the phone back apart and I found my issue. I managed to tear a part of the ribbon cable, cutting 7 of the leads.
So it looks a new digitizer is in my future.

[Q] One S Touch Screen/Digitizer Replacement

Hello all I hope someone here can guide me because I am at a loss.
A couple weeks ago I cracked my screen and have been searching for a replacement
Digitizer since then but everywhere I look is either out of stock or comes with the
LCD (which I don't need ).
I know this is a bit forward for my first post here but I am hoping someone
may have a suggestion as to where I might be able to pick one up so I can finally get my phone back to it's
original glory.
Thanks in advance for any help/suggestions on this matter.
In htc digitzer and screen are unity, so if you have problem with touch, you have to change all screen.

From what I have read the glass and the digitizer are one piece but it is possible to separate the LCD in this guide :
androidforums. com/htc-one-s/609247-how-fix-htc-one-s-screen.html
Problem is every website I have looked at the glass/digitizer is out of stock and it's triple the price to get it with the LCD.
you can't separate, because in amoled all layer are connected in fabric.

i repair phones for a living. and i'm telling you, DO NOT ATTEMPT TO TAKE APART THE DIGITIZER AND LED!!! most new htc phones, like the iphone 4/4s and newer samsung phones the glass and display come together. yes, it is possible to take them apart, it's more hassle then it's worth, you are almost guaranteed to break your display (unless you've done it a few dozen times) and then when you try to put everything back together, it will not fit together right because the LED will be warped by your pulling and bending it out of the frame. also, any part you see sold as just the digitizer is either not the correct part and even if it fits and works it is not OEM

I appreciate you taking the time to clarify that for me, I had hoped it would have been easier than that. I can start looking for the correct part now and finally get my phone sorted out.
Again thanks for your help.

[Q] Repairing a damaged screen

First, the story:
I dropped my phone and broke the screen. The screen is always black now, but from the sounds the phone makes, it sounds like it is still working.
This place has instructions for replacing the touch screen digitizer and the LCD; they also sell these replacement parts (for $40 and $35 respectively), (I had to obfuscate the URL to post this, so replace the underscores with periods):
www_repairsuniverse_com/htc-mytouch-4g-slide-screen-repair-take-apart_html
I'm not quite ready to move on to a new phone yet, so I am planning on trying to fix this myself. I guess my other option is to see how much it would cost for TMobile to fix it for me, but I am guessing that they want too much. My phone is rooted (s-off) and running a Bulletproof 1.1 image.
Now, my questions:
Has anyone here successfully been through this process? Any advice would be greatly appreciated.
I have not yet attempted to disassemble the device to futher assess the damage, so I do not know exactly what is broken, although the glass is certainly broken, is this what is referred to as the "touch screen digitizer"?
LCD is the actual display. Digitizer is the glass that sits on top of the screen (the part you touch)
If your LCD is broken, the picture will be messed up
http://forum.xda-developers.com/showthread.php?t=1592219
Replaced the glass (digitizer) without issue. returned the phone to t-mo since prior to that it was having an issue with the hardware camera button being stuck always on. So long as you're patient, technical, and have a steady hand, do it, it's fine, just follow-the step-by-steps, and keep your screws and parts seperated at each step
I ordered a new LCD and digitizer, and will probably have some time to do the repair mid-late next week.
I went with the Sony version of the LCD based upon discussion in the following thread (in the 3rd post iynnoji says they tried a Hitachi LCD but it did not work):
http://forum.xda-developers.com/showthread.php?t=1526595
It would be nice to know if the Hitachi LCD is incompatible, or if iynnoji had a bad component or some other issue.
Anyway, thanks for the feedback gtmaster and eclipsed. I'll update this thread after I attempt the repair. I have to admit, I'm sort of glad I broke my phone, since learning to fix new things is such an enjoyable process. Hopefully I'm still happy about this process after I finish the repair and attempt to power the device on .
Yay! The repair was successful! Not having a cell phone really made me aware of how useful one is. Next time I upgrade I'll keep my old device around as a backup.
So some notes:
The screen assembly was really difficult to remove, due to the large amount of adhesive. When I took it off, the LCD split in two, with half attached to the screen assy and the other attached to the adhesive. Luckly I was intending on replacing the LCD anyway. Anyone else performing a screen or LCD repair should beware that this is a difficult step, and will take time and care.
The Sony LCD (P/N 60H00523) works fine with our device. As I previously mentioned, it would be nice to know if the Hitachi LCD (P/N 60H00512) works, as its $15 cheaper.
I wasn't careful enough when placing the LCD on the digitizer, and managed to a few dust particles sandwiched in there. Not a big deal, but if I were to do it again I'd check my work before assembling the rest of the phone.
I used the adhesive paper sold at repairs universe around the edges of the digitizer and put the phone in the oven @ 170 F for 5 minutes after assembly, then waited 10 minutes before using it. Everything seems solid.
Again, thanks all for the help.

Backlight doesn't come on unless i bend the phone

So on my Nexus 5, the backlight started going off randomly... tapping phone would bring it back..
Then eventually it went out and i had to bend/flex the phone and it would keep working a while..
I contacted support then, but one time i bent it a little to get it on and the frame (plastic outer edge cracked), doh.. Now, of course, they will not give me a warranty repair because the device is physically damaged. So i tried a new screen, no dice. Now i have two good screens and a phone that still wont work unless i bend the crap out of it. Anyone else see this problem? Worth trying to replace motherboard? or should i just sell parts (new screen i bought, old screen, battery, etc) and buy a whole new phone... There is one specific point where i can bend it and backlight comes on, but i cant find a short or loose connection anywhere. I have had the thing COMPLETELY apart and back together multiple times. I should mention, it works totally fine when backlight is off, just no backlight so i can only see it in super bright direct illumination.
Any ideas???
Take it to a mobile phone repair shop.

Fixed for now! Woohoo! Based on the position of where i had to flex it, i tried a little gap filler... a folded piece of paper, between the SIM slot and the back frame. With everything screwed back together, it just puts a little pressure on that area of the main board.
Now the only problem is the screen i bought is defective (lines all up and down it) so now i have to disassemble again to put the old one back in.... oh joy, now to return it through ebay... I'm sure that will work well. Either way, phone working again! FYI, this phone is REALLLY easy to take apart and put back together.
EDIT: F.. snapped the end off one of the little antenna cables (the black one, on the right when looking at the uncovered back of the phone) when redoing the screen. Anyone know what that is for? WiFi and cell data signals seem ok.. Looks like a diversity antenna for something, because of all the others at the tope. Maybe google will have an answer.

Check Bluetooth/try calling/using data just to be sure.
Do not discuss something on how to make fool of insurance company or even an warranty, It's not allowed here. Thanks

[Q] Cracked Screen Question

Hi All
Recently i got careless and i accidentally cracked my nexus 5 screen after dropping it on the ground
Currently the touch screen works but there is a problem. I am unable to answer calls as the screen goes black and does not turn on again until the person has hung up or until i reset the phone. Also when i try to call out the screen turns black as well and exhibits the same symptoms as listed above.
From people who have had experience with cracked Nexus 5 screens, do you think replacing the digitizer + lcd will fix this issue or did i screw up something big
Thanks
It sounds like the cracked glass is affecting the proximity sensor. Replacing the screen /digitizer should fix the problem. Replace the whole thing including the bezel.
Any chance you could explain why the bezel also needs to be replaced as well?
It's easier to use the screens that come with the housing, you just switch internals and pop the back on. As for oem replacement screens with housings, I've read mixed reviews. Some say theirs is perfect. Others complain of different textures on the housing, or missing ear speaker mesh. Some say their replacements have massive light bleed. If it were my phone I'd pay the extra 25 to 50 bucks and send it to lg for repair. They charge 150 dollars. Then you are guaranteed to have it be perfect again. Plus their work and parts are warrantied. Play it safe and send it to lg imo.
Edit: Also if you did break anything else they will fix that as well.
