When I look at Google Maps on my Galaxy 8, touch the blue dot for my location and hit calibrate - the result is a "High" calibration level. I can never get it to change on the Samsung Tab E. The figure 8 only keeps me at "Low".
Welcome to the forum as a new member. The location accuracy is dependent on the location settings you have allowed and set on the device. I would install a GPS test app on the Tab and see what accuracy you are receiving from the satellites.
