Everything went smoothly and the screen is functioning perfectly.

However, the fingerprint scanner is not. I get an error message saying "Cant use the fingerprint sensor. visit a repair provider or g.co/pixel/fingerprintunlock"

What else do I need to do to get this working?

I thought my Pixel 3A had faulty USB-C port as except charging it does nothing else i.e File Transfer and USB Debugging.

I ordered and replaced the USB-C port last week successfully but the result is the same.

Anyone else faced the same issue ?

Thank you

Google has a a fingerpint repair tool at https://pixelrepair.withgoogle.com/udfps but it says my firmware is too new for the tool.

Now I have no fingerprint scanner and I used it on all secure apps.

Note that everything else works perfectly on the phone. I've tried already:

• Testing the SIM on another device -> Worked fine
• Testing a second SIM on pixel device -> Also not working
• Clean SIM
• Reset Network settings

My P7a (lynx) shut down randomly several times, followed by the phone being unwilling to boot for an extended duration. After each shut down, the amount of time it took for the phone to boot got longer, and the phone no longer boots at all. When the phone was working between shut downs, some functionality would usually be broken. Functions I observed inoperative were (not all together - on different instances): Cellular modem (only connects to EDGE), Camera (none start), and WiFi (Cannot detect any networks).

When the phone refuses to boot, the upper third of the phone remains slightly warm, even when not plugged in. The warmth goes away after being unplugged for an extended duration (hours) and returns when it is plugged in. The phone screen is black, and nothing happens when every combination of power/volume buttons is pressed, held for 10s, held for 60s, or held for 2-3m.

When the phone does boot, the indicated battery % is close to the same as when the phone shut down, even if it has been plugged in for hours.

Judging by the coolness of the AC adapter, I believe the phone does not draw much power when plugged in.

Unsure where the fault may lie. I am willing to disassemble the phone if it is a hardware flaw. Anyone have an idea of what is going wrong?

I just replaced the screen of my Google Pixel 4a smartphone. It seemed to be running fine, but from time to time, the multi-touch feature of the screen stops working. I get stuck with single touch capability (one finger a a time). Then, after some time, it starts working again.

Using "developer options", I managed to confirm that the screen only detects one finger (while it detects up to 10 at a time when everything works fine).

It does that during continuous usage session of the phone and screen. It sometimes works fine for several minutes, and sometimes for a few seconds only.

Turning off and on again the display doesn't fix it. Rebooting the phone doesn't fix it. I reset completely the phone by reflashing the official Rom, then another LineageOS Rom, it didn't fix the problem.

What would you try to fix that ?

I fear it comes from a hardware failure. Is there a way to contact iFixIt to get a free replacement screen ?

Thanks in advance for your help.

I recently opened up my Google Pixel 5 for a battery replacement. During the process, I ran into a bit of trouble with the motherboard contacts located near the front-facing camera.

One of the two large pogo-pin/contact pads (highlighted in the attached photo) detached from the board. Thinking it was held by adhesive, I tried to secure it back using a microscopic amount of super glue on the side, hoping the pressure from the screen would be enough to maintain electrical contact.

Unfortunately, after reassembling the phone, the earpiece (under-display speaker) is completely dead, though the bottom speakerphone works perfectly. I suspect the glue acted as an insulator or the alignment is slightly off.

I have a few questions for the experts here:

1. Identification: Can someone confirm these are indeed the primary contacts for the piezo-electric screen actuator?
2. Original Attachment: How are these pins originally attached to the board? Is it standard SMT soldering, or does Google use some form of conductive adhesive/thermal bonding here?
3. The Fix: I only have a standard soldering iron and a strong magnifying glass (no micro-soldering station or microscope). Is it suicide to try and solder this back with a regular (but very thin) iron?
   • If yes, what’s the safest technique to avoid bridging nearby components or lifting the pad further?
   • Should I use a specific type of solder or flux for such a small area?
4. Alternatives: If soldering is too risky, would a conductive silver epoxy (Contactol) be a viable "cold" solution, or is the signal too sensitive for that?

I’ve attached a photo of the area. You can see where I attempted the glue fix (in the red box). Any advice would be greatly appreciated before I risk opening this fragile screen again!

Thanks in advance!

I also scratched the black square layer underneath the battery, which I think is some kind of graphite sheet for heat dissipation, and now I can see three tiny gray triangles, each about 1 x 1 mm.

What should I do? Is the battery unsafe now, and should I avoid turning the phone on?
