I have en issue with the gps only when my phone connects to 5G i have done all troubleshooting steps but they don't fix it i think is the same bug that happened to the verizon note 5G that an update fixed it
I usually almost always have my phone on High Performance Mode. I've noticed my GPS also doesn't work super great with 5G enabled. Also using the Note10+5G on T-Mobile. If I go to settings and turn it to LTE/3G/2G mode, GPS works amazing.
