I was wondering if someone else has this issue. When I use Google maps in areas with varying data networks my phone seems to lock itself to whatever network it had when I started using Google maps. This affects the whole phone while Google maps is running and using data (eg, searching or guiding thru a route). Once the app is stopped normal connectivity function is restored. This also happens during a phone call using the oneui native phone app.
I experienced this most recently yesterday while using Google maps to guide me to the parking location of my car through a busy town centre. I arrived there using waze which didnt seem to trigger the issue to occur, though this was while driving to the city, a use case for which the issue doesn't occur as reliably when using Google maps.
