i turned on location on new tablet and only option I had was battery saving mode.

[Android Central Question]

i tried a number of things like restarting and closing the nav app, and I may have seen a high accuracy option the first day I go it (yesterday) but didn't test it then. could the gps receiver have just died? i have android 7.1

Are you sure the tablet has GPS? What's the model number?
