Hi @abluedog,
For customers experiencing any issues with their service, we recommend the best thing to do first is check if there's an outage.
Check our Service Status page as this is where we list outages for TPG Internet, Mobile, Phone and Email.
If you're able to access your email without any problem on TPG's Post Office, laptop and tablet, this only means that your TPG email is properly working.
We suggest that you check your Samsung Mobile Email Settings and we recommend having a read of this community article which may help resolve the issue: Setting up email on your Iphone and Android phones
