How fix Face ID after replace front camera? - Google Pixel 4 XL Questions & Answers

Hello. How to get FaceID to work after replacing the camera module. Are there ways?

I didn't think the front camera had anything to do with face unlock, it's the Soli module that does face unlock.

I have seen records that after replacing the camera module or motherboard, such a problem arises. But there are not many of them, either people do not bother, or there is a way to restore everything) It is desirable without sending to Google

I suppose you've done a factory reset?

Clear system cache on boot menu.
Do a hard reboot (not reset!)
Clear data of all associated apks including probably Android Services.

If you did a hard reset than what I said is irrelevant.

So the cam module's firmware version isn't compatible with the system firmware version?
Sounds like the damn modular car computer systems... a horror story.

I teardown my 4xl and replace rear camera module. After assembling it again, rear camera worked fine, but front camera and faceid cannot work. My phone cannot detect front camera. It show black screen when flipping from rear to front camera.
WHAT I DID:
1. Factory reset -> not work
2. Flash various factory firmware-> not work
3. Changed another whole front camera + sensor module -> not work.
Please help.
Thanks.

It seems the problem is physical... hopefully.
Closely inspect the ribbon cables and contacts of the front cam for damage or misalignment.
Use magnification as needed.
Make sure any ground points to this module were not overlooked. A longer screw perhaps?
The chassis is aluminum so that is a potential grounding point for mounted components like the front cam.
You did disconnect the battery first, right?
I looked at the tear down vid... I feel your pain.

Just like iPhones parts
pixels parts are married to the motherboard each part has a special SN number the motherboard will require
replacing them may cause a problem

So where's it stored? Firmware?
Or does the cam module need to be flashed?
Or both?

Front Camera

I think my front camera is broke. I just got my Note 8 and went to setup both Iris and Face unlock and neither would work. I was fiddling around and opened the camera app and went to selfie mode and the camera app keeps working but the screen freezes and no picture from the front camera on the screen. I then did some research and found *#0*# to test the hardware and got the following errors below
Checksum Error
Data Line of Front Camera Fail
Makes me think it's a hardware issue but I thought I'd check here first?
Thanks
try a factory reset if it still fails then yes hardware.
Ya I factory reset it. Same issue. I'll work on returning I suppose

The Iris camera is independent of the front camera, an independent module I mean.
Try testing the hardware. Use this code *#0*#

Mi A2 Camera Focus Issue

Hello, my Mi A2 seems to have a strange effect when focusing on the primary lens. I would just like to know if this is normal or not. It seems when on the low light lens the focus is even across the image but the primary lens it seems to wash from one side to the other.
Here is a video to illustrate.
Does anybody else's do this? Thanks!
I've been having the same issue for a while now! It's very annoying and I have no idea how to fix it! I've been using the low light lens and just taking pictures with that. I cannot tell if it is a hardware or software issue either. I'm going to install a custom rom soon, just haven't had time to do it, so hopefully that fixes the issue!
i think it's a software issue, because after capture everything is OK

I still have issues after capture. If I'm capturing text the top half is unreadable in portrait because it's so blurry, and when I tap to focus on the top it doesn't help.
Same issues here
I have exactly the same issue... It seems like the extremes of the picture are better and the sides really blurry. For text is really bad, and also for pictures when you want the focus not being in the center. As you mention, touching the focus does not help.
I have no solution for now, thinking on sending it back...
Doubed HW issue
I'm sorry to say I feel it like a HW issue as I am facing the same issue with GCam in my MI A2.
i too have the same problame even after capture...
It's fixed on my phone now, unfortunately I had to get a new camera module. The issue is likely caused by a misaligned lens element, so the only option is to swap the camera module or warranty the phone. Mine works great now. Shouldn't have had to fix it but I guess these things happen I guess.

It should be pretty straightforward, here's a teardown video: https://youtu.be/mo92gAwKv6s. That should walk you through getting the module out.

Can you send a link to the module you got? There's several between eBay and AliExpress I've seen, but am looking for a reliable one.
I have the same problem, I think it's began after update to pie 9, Is it possible? I try everything like clear cache, factory reset, hitting the camera. What is your solution ? Only change the camera with new ?

Mi A2 changed camera module - Camera error, cannot connect to camera

Hey
So I had problems with my camera not focusing when trying to take pictures from very close distances (small figures within 10-15 cms), it was all blurry - I tried different options and decided that software changes didn't help the problem so I ordered a new camera module and changed the part. I read that dropping the phone might lead to the lenses getting somehow disoriented and there's only solution to change the module..
Now after replacing the old module the camera app can use the front camera but when I swap to the primary back camera an error occurs and it claims it can't connect to the camera and the camera closes. Is this new module that should be for A2/X6 somehow still somehow incompatible or do you guys have any idea what might the problem?
I've tried to clear the data from the camera, I've reset the factory settings - no help.

Well IMHO, this kind of thing is better leave it to the authorized people @ expert.. I mean you sent it to service center or phone shop and let they do the replacement.. Me itself have experience of dropping my A2 from second floor and screen is badly shattered.. Although I know how to replace it but I won't do that.. I ordered the replacement parts and then sent it to the shop and let them do it.. I just pay for labor cost..

Camera not focusing after 1.8x

After zooming to 1.9x camera turns blurry in 95% cases.
Here is screenshot:
https://imgur.com/a/vCUxw2V
I tried to uninstall updates, clear cache & app data, safe mode, with no result.
I have also tried open camera app same issue.
I have also cleaned camera with cloth.
Camera ver 8.x with latest Android 11
I came to conclusion, that it is telephoto camera issues and need replacement.
I am planning to replace it with camera from ifixit.
I have also read in some places, that it is OIS fault & does camera include OIS? Will camera replace fix this or something else might be necessary?
Thanks!
Of course if it may be software issue any suggestions are welcome!
Hey!
So the first thing you could do is factory reset the phone and uninstall all updates from Gcam. Try using Camera PX as well. If you still get the problem, then you may have a damage camera.
If you decide to open the phone, I would recommend you try to clean the camera it self, but don't be brute as they are very easy to break. I would use a cotton to clean up the lenses, and then try to see if the issue disappears. If it still don't work you will need to replace it.
About OIS, I don't believe is that. OIS moves slightly the lenses to correct the movements of the hand, so the image is more stable. It has nothing to with autofocus. Both lenses on the Pixel 4 has it.
Let me know how it goes!

I am assuming that the phone is in great shape, no broken glass lenses and things like that. Also, no water damage, because if this isn't the case, then the problem can be other.

Shockingly poor front camera quality

Hi all,
I recently purchased S20 FE 5g (Snapdragon, india) few days back for my wife. The screen of her previous phone Redmi k20 broke after a fall and screen was not available (and even if so it was going to cost around 50-60% of phone's original purchased value. So instead we decided to buy new phone. And after lot of back and forth we settled for S20 FE.
The main camera is good. But the front camera and selfie is really poor for this kind of phone and price. In fact Redmi K20 which was almost half of the price of this one had better front camera.
The photos are grainy and blurry half of the times. And smoothening effect even after turning off all filters. This doesn't have autofocus I am aware. But most of the phones do not have for front camera.
Night mode and Gcam improves it somewhat but overall very disappointing front camera.
I checked with service centre and they mentioned there are no hardware or software issues. So I cannot get any return or refund as well.
Shockingly very few reviewers mentioned the issues with front camera and overall camera reviews were good. Now after doing some research see many users complaining about front camera. Seen some posts here and many on reddit as well. My 3 years old Pixel 3xl takes miles better photos and even almost 2.5 years old Redmi K20 was better in front camera marginally which was almost half of the price.
Given S20 FE was released almost 1 and half years back I do not have any hope of fixing the front camera by software updates from Samsung (they would have already done by now)
Or if anyone here have any idea if the front camera can be improved by some tweaks? (already tried night mode and gcam which are better but anything for normal shots?)

Is it better than the stock camera?
stock camera and stock camera app are two completely different things. Sometimes custom apps perform better.
You should look at it, then you can decide. I have the luck that I did not buy the same phone..
I bought the S20 FE and back then there was a screen bug that was enough for the seller to take the phone back - you'd have to search for the thread but it involves multi-touch on the screen.
There's an app you can DL to check it but it shows as when you do multi-touch swipes the screen malfunctions. Might work with your retailer as a faulty phone?
I would return it.
Try clearing the system cache and cam data first.
If the cam app has been updated, roll back to factory loaded version.
Also try in safe mode to rule out a 3rd party app causing the issue.

It's better to find the root cause. A factory reset is the last option. It's used after a major firmware upgrade, if a poorly written app alters hidden user settings or in the case of malware.
Problem being is you never learn what the root cause was... if the issue reappears in the future.
In the long run a conservative troubleshooting approach wastes less of your time. Use factory reset as a last ditch option. Always clear the system cache before you go full nuke as it can fix many strange glitches.
Also try a hard reboot (simulates pulling battery).
Did you do any firmware upgrades?
Did you use SmartSwitch to help load this phone?
If so factory reset. Do Not use SmartSwitch on the next load...

It's called Touch Screen Test - there's a thread on Reddit about it here...
NOTE: Put a www. in front of the addresses and copy them to your browser - if I put the link it posts the entire threads in this post, which seems a bit impolite for others.
reddit.com/r/Galaxy_S20/comments/j6cdu0/s20_fe_5g_smg781bds_has_a_touchscreen_hardware/?utm_medium=android_app&utm_source=share
I found another thread that claims it was fixed in updates so check you have the latest firmware also.
reddit.com/r/Galaxy_S20/comments/jau31s/s20_fe_touchscreen_issue_thread/
For me i found that i get the touchscreen issue, more like the glide keyboard plays up
Reboot always fixes it.
And its usually after phone has been on continually for days on end that it acts up
As for the front camera, I agree its poor.
I find i have to add colour to the images and chuck on the warm filter to full to get warmth.
I had the same bad luck of buying this phone. Have been facing the same issue. But there is something surprising I have found in the front camera of this device (S20 FE). See the difference between the photo mode and video mode of Front camera. I found the difference quite noticeable. This confirms that there is nothing wrong with the front camera of this device but definitely with its software. In video mode of Front Camera I see no lag as in photo mode and the camera is as smooth as it could be. Kindly see the difference and do let me know.
Regards
Robin Arora
