Unexpected GPS Drift on My Pixel 6 While Hiking Remote Trails

I took my Pixel 6 on a week-long backpacking trip through some pretty remote trails in the Cascades. I rely heavily on the phone's GPS for navigation and recording my route. About halfway through the trip, I noticed the GPS location started drifting by a few hundred meters, especially when I was in dense forest or near steep ravines. I tried toggling airplane mode and turning location services off and on, but it didn’t help much. I also updated all apps before the trip, so I assume the software is current. I want to understand if this is just a limitation of the phone’s GPS hardware in tough terrain or if there’s some setting or app that could improve accuracy. Has anyone experienced this kind of GPS inaccuracy on Pixel devices during backcountry hikes? Are there any tricks or apps that help stabilize GPS signals when the terrain is challenging?
