Replaced battery in my N5 - now no trusted face or trusted locations

[lchiu7]

This seems very strange. my N5, stock and unrooted (5.01) battery was getting bad so I replaced it with a unit from ebay. It looked like a genuine OEM battery but I suspect it wasn't.

And despite all the videos on Youtube etc. saying you can prise the back off the N5 without breaking anything I managed to break two tabs

Anyway after I put it all back my first heartstopping moment was NFC had stopped working, both for charging and for communications. A quick Google search revealed that was because the back had not snapped on properly so the antenna in the back was not contacting the motherboard contacts properly. A quick press of the back the case, a click and all was well,

But now the phone won't do trusted face or locations which it did before. If I go to trusted face and choose improve face matching I receive an error Couldn't start finding your face. And now face unlock never works as well as trusted location (my home).

I can't believe a new battery would affect that but perhaps somebody in these forums might have some knowledge of this problem?

I will wait for 5.1 to see if it fixes the problem, else I guess I have to live with it.

Thanks

Sounds like maybe the front facing camera connection might have been disturbed during battery installation.

If it was me, I'd go into the camera app and see if the front facing camera is working properly.
If not, pull the back off again and check around the camera for anything loose. Verify your antenna connections.

Best of Luck

That one of the first things I tried and the camera is fine. Also GPS works fine so trusted location should work.

As you mentioned, waiting for the 5.1 OTA is going the be the best option short of factory resetting and losing all your data.
Hopefully the OTA will fix it for you when it arrives to your device.

If you prefer not to wait on Google, you could Download the 5.1 OTA and ADB sideload it using the STOCK recovery.

Looks like you would need to follow :
Scenario #1
You are completely stock. Unlocked or Locked bootloader. No root permissions.

Best of luck

The problem is not from your battery.
Trusted places and faces are broken after the last Google Play update on a number of Nexus devices after they added the "on-body detection."
Some users get it to work, some temporarily, but it is not an issue with your new battery. From the forums i read, some users (not Nexus 5 ) got it to work by turning smart lock off and on, re-doing your locations in google maps, side loading the Google Play Services apk, uninstalling the Google Play Services and reverting it to previous version (mine is grayed out.)
I notice huge battery drain coming from the Google Play Services then I disconnected the GPS and it was no longer draining. I am assuming it's having trouble or a bug where it's searching my location for the Trusted places and draining my battery. This is only an assumption though. Hopefully it will be fixed in a future update. I still have not found a fix for my N5 or N7 2013 yet.

Just so others are not put off ive changed my Battery with no issues and have taken the back off 6 times. No clips broke. It is important to make sure all clips are pushed home and you should gently press the back allover as there are a lot of connections on the back that need to make contacts with the board

I got the OTA update for 5.1 and it's made no difference. Might have to look at some other solutions.

Not sure if that applies to me. I had the problem after I replaced the battery (though it could be coincidental) but before 5.1 where I understand is when on-body detection was first implemented.

I managed to get trusted places to work by walking around my section and getting the phone to recognise a new location which is basically the same as my home but with a different name. That seems to work but I still cannot get face detection, either with unlock or improve matching.

I found the reason for my large battery drain, it was one of my weather apps refreshing through Google play Services. I also did a temp fix for Trust Places like the other user did. I added two places next to my house, close enough to all cross each other. That did the trick for now.

Here's what worked for me

I got a phone call when my Nexus 5 was locked and instantly Trusted Face crashed and gave me a force close message. Here's how I managed to fix it:

1) First, I removed the existing face data and turned off Trusted Face.
2) From Settings --> Apps --> All, I found Trusted Face and Cleared Cache, Data, Force Stopped the app and then disabled & enabled the app.
3) Rebooted the phone holding the power button (Not through the menu)
4) Turned on Trusted Face and registered my face.
5) Then I had coffee, but that's not relevant to the case.

Note: I know some of the above steps are unnecessary and repetitive, but nothing else worked for me.

Good Luck !

Thanks. I tried that and now Trusted Face is working again.

I'm glad it worked.
