Samsung Update = Pokemon Go Unable to Authenticate - S20 issue?

[C_Schaff]

Is anyone else having issues running the Pokemon Go app on their phone?  I used the app for about 15 minutes this morning with no problems.  A notification popped from Samsung saying an update was ready to install on my phone (Galaxy S20).  The update completed and now Pokemon Go keeps saying Unable to Authenticate my account (or any other).  Another phone in the family (S20 Ultra) also had an update but PoGo runs fine, it's only me (2 other players in the house use S8 and S9 and have no issues either).  I have force-stopped the app and cleared the cache.  I have restarted the app and the phone.  I have tried with wifi, 4g, and 5g connections.  I have removed and reinstalled the app and the Google account.  I used a different phone to link my account to Facebook.  Nothing works.  Any suggestions would be greatly appreciated.  I've reached out to Niantic but they just sent me to an article telling me to do what I've already done.  Since this happened immediately following a Samsung update, I am hoping someone on this forum is having similar issues and can find a fix.  Thanks.

We experienced exactly the same; one S20FE working and the other wasn't. Tried and checked everything but nothing worked. Something was blocking pogo and we could not find out. Ended up with a factory reset and that worked.

I am having this issue as well!! Frustrating. I would rather not do a factory reset. Have you been able to resolve on your end? thanks!!

I'm having the same issue. Uninstalled/reinstalled and removing/adding Google account and I can't login with Trainer Club as well. This only happened after my S20 updated yesterday. It will not authenticate. Very frustrating.

Same issue here.  S21 Ultra 5g. I have tried all the same troubleshooting steps that you've mentioned. I found your post when I googled for conflicts between the app and the phone 🙂

Same issue on S20FE

S20 same problem. It works fine during the day but then won't let me log in after around 8pm until the next morning. It's like there's a time limit on it...

Hey, I actually got a real piece of troubleshooting help from Niantic! Put the app in a secure folder and run it from there as a work around. So far, it seems to be working.

THANK YOU so much for taking the time to add the fix it worked for me as well. I didn't even try to ask Niantic based on past attempts to get help.

Yeah, I didn't actually expect anything useful from them either, usually just the link to standard troubleshooting that we've already done by the time we reach out to them...
