Fingerprint scanner not working after screen replacement - LG G8X ThinQ Questions & Answers

So I dropped the phone a couple times and it held up well the first good drop but the LCD went out after a slide off my bed. So much for mil std..... Finally got the screen replaced at a local shop and ever since my fingerprint scanner isn't working at all. Can't find any answers on this but it seems to be that the screen replacement leaves a gap or something? All other touch works fines. Any help or advice would be appreciated.

My wiza200 touch screen intermitten

Hi all,
Has anyone experience with a problem when the touch screen intermittently works, especially when you press/hold hard on the sides of the face of the phone. Without pressing down on the side, the top menu (start... x) most of the time are either unresponsive or respond as if you press elsewhere on the screen.
I'm thinking of open up the phone later tonight to troubleshoot, guessing the screen digitizer is loose or, HOPEFULLY NOT, cold solder somewhere. But if you'd heard or faced this problem before or even have an idea on what has caused the problem, I'd like to hear from you. Please help!
Thanks!
Adding info
Oh yeah, did I forget to say that not just the top of the screen, the middle part as worst. The only part of the screen is still responsive is the bottom. If I press down or punctual around the face of the phone tightly enought(?), I'd be able to have the good touch screen for a little while (5... 10 minutes) before it gone weird again.
Fixed... for now
Well, I jammed a couple of thin plastic to the bottom of the screen within the housing facelet behind the t-mobile logo... and it works... for now.
I still intend to disassemble the dawn thing as soon as I realize such quick fix has become unpractical or no longer work.
I will check back to this post again, so if you are interested, don't hesitate to reply, I'll try anything when desperate.
How long have you had the phone?
How do you carry it around?
If you got the phone recently and started carrying it around by putting it in your pants pocket, then you find the screen sometimes doesn't work well, those facts are related. A couple of years ago people used to always complain about this, and some recommended rubbing your finger firmly around all edges of the screen for a temporary fix. Others recommended forcing a business card under the metal at the edges of the screen. I got a leather belt case for mine, and the problem went away.
If you've had the phone for years and it just now started acting up, the problem might be related to a cable, connection, or something. There is a wizard service manual online. I've used its instructions to replace a screen, with no bad issues.
Good luck with your phone. The wizard is a bit old, but still pretty nice.

[Q] Galaxy s2 screen repair fail - buttons dont work now

Good Day folks, here is the long and short of it.
Galaxy s 2 fell and the screen broke
I bought a new screen
Replaced the screen BUT two big problems occured.
1. The screen appears to have less colours than my original screen
2. NONE OF THE SOFT KEYS WORK, HOME, MENU AND BACK DO NOT WORK.
Number 2. is the big problem. Does anyone have any idea how these buttons work?
Even when I press the buttons directly with my fingers with the buttons off they still do not work.
Im baffled. Please help.
I also have attached pictures of the button area
It happened to me, I removed the screen, I replaced from beginning and it worked...
Hi Collado, do the white things behind the buttons have any electronic functionality or are those just things to make it stick?
To all future readers. I found out what the problem was. Basically,
The home, back and menu keys are all connected to a single ribbon. It appears there is a tiny piece, connected via the back key. That was torn while i was ripping off the the screen and digitizer.
See the picture attached
How much did you pay for your replacement screen and where did you get it. My digitizer is broken due to a drop. My front glass is perfect but the digitizer is completey shot. How difficult was this project?
Hi Johnboy
I cant remember the price of the digitizer offhand but make a check on ebay.. that is where i got it.
Difficulty is high as you need the minature tool set to do this effectively and a gentle touch.
However, it still appears as though the screen I bought has less colours.
Sorry to jump in and unintended hijack
I also dropped my S2 and cracked the screen, and after checking around dropped it in to the Geek Squad at CPW. Who duly replaced the screen and digitizer for £80. Only problem is the screen seems less bright and if moved off the central viewing angle the screen dims, as if it wasa standard lcd and not the orginal AMOLED screen. Does anyone know if they make lesser screens or was it fitted badly.
Any advice greatly appreciated.

I would go back with it and complain.If you dont get satisfaction then do an impression of the guy that goes into the pizza shop in "rise of the foot-soldier" film.

[Q] screen repair/troubleshooting

Hey guys I bought a used note 2 VZW
long story short the screen was busted and I repaired it, the screen is unresponsive to touch (it will respond
but it's very iffy usually having to tap on the screen pretty hard to get it to recognize the finger.) it was spazzing out too
with nothing else touching the screen i turned on show pointer location and it was moving extremely rapidly up and down
the left side of the screen.
but when the S-Pen is removed and used it works fine.
the replacement part i used was for the VZW model number i605/L900 is it possible the replacement part had a bad digitizer?
all pins/connecters were seated with care. it worked fine for about 3 weeks, then Bam. no dice, any way if anyone is interested
in it pm me, i've got a note 3 on order from BestBuy.
I'm giving up on buying used and repairing them, i'd rather buy new at discounted prices. than pay near full price (including replacement
parts repair it and it still be screwed.)

Mate 10 pro touch screen not responding.

Hey guys,
Just a quick question. I've got one of the first release Huawei mate 10 pros. Dropped it from about a hip height onto tile, no visible crack or damage to the exterior or screen but since then I haven't been able to use the touch screen.
I get a bit of the slide from the bottom and everything else works but I can't actually use the screen because I can't swipe patterns or type in, it's basically a dead screen, but if the whole screen was out of commission I wouldn't get any slide action at all.
Need the phone for work, any quick responses with experience in the area would be much appreciated.
Cheers.
I'd say its definitely hardware related, as in broken.
You'd have to get it replaced.
Even if you get no cracks the digitizer can be broken.
Aw man, I was really hoping there was some sort of software bug that was causing this, well I'll stay hopeful that this has happened to someone else until I have to claim the warranty

Click to expand...
Click to collapse
It has happened to me (sort of), but I got a crack and the touch screen below the crack didn't work at all, top part worked fine. Or vice versa, can't remember but one part was still working. This was on a Samsung though.
And on an iPhone the screen completely shattered, but touch was working fine. So the digitizer wasn't hurt there, but it still required a touch + digitizer replacement as they are glued together.
If there's no crack, then it might also be a loose connector.But even so, you would need technical assistance.
If the warranty is still valid and there are no visible signs or scratches from that fall, maybe Huawei will repair it for free.
Yeah I'll be following it up with optus because it's still on a plan. I shattered and bent my mate 9 and as soon as there was a crack the digitizer went. Might as well use the warranty because if I open it up myself it'll void it for future use.
Thanks for your input guys.

New Mate 20 Pro screen replaced but finger print reader is not working.

I recently got my screen replaced but everything else is working but not the finger print reader. I tried to delete and put new finger prints in as a new record.
The person said this can happen when replacing a new screen.
Anyone got ideas how to get it working again for is there a software to download or something, appreciate any feedback.
Two type of screen , with and without fingerprint . Check aliexpress you will know it
you might replaced your screen with Chinese version which doesn't have fp scanner.
Thanks guys might be the reasons, all good, it's not a deal breaker, at least I got it fixed but it's not cheap, I would say anyone who does not have a screen cover on it and a good case should get one because I thought it wouldn't break on me from a fall less then a metre and it did.
