Google Pixel 3 does not read NFC Type 4 tag as in the NFC writable example

[Quark]

Dear Nordic,

We have developed a product utilized the NFC readable/writable feature of NRF52832. We have tested it against some of the HTC, Sony, Samsung, and Google phones. It works for most of them, but not all. We found that Google Pixel 3 and 3 XL (probably also the older model) is having trouble to read the NFC Type 4 tag (Type 2 is OK). This issue can be confirmed with the NRF52 DK with the NFC Writable example. Would you please test and confirm the result and update an analysis result? 

Thank you so much for your help, we are about to enter mass production, but we really need to know why some of the phone could not support reading the NFC tag, thank you!

Hi

I just tested it on a Pixel 1 XL (Android version 9), and the Writable NDEF Message example worked like a charm. I will try to get my hands on a Pixel 3 as well, to see if I can recreate this issue. Are you testing using the example itself or do you have your own project that you're testing on? In some apps, the phone needs to enable location services for certain services to work, so it was just a shot in the dark really. By casing, I meant if you had any external casing around the phone, but this shouldn't be the cause of the issue either.

Do you have more than one Pixel 3 available, so we can make sure it isn't just one defect phone? I'm trying to narrow down the issue further, so if you have any more details, please share. This does seem though, to be a problem with the Pixel 3 phones, as there are other posts with various NFC issues out there. https://support.google.com/pixelphone/thread/3148141?hl=en and https://forums.androidcentral.com/google-pixel-3-pixel-3-xl/925255-nfc.html.

You could, of course, try what these posts suggest. Running NFC in safe mode, clear your cache, uninstall some apps from your phone, and even factory reset it.

Best regards,

Simon

I've turned off LBS and the result is the same. FYI
