I've been struggling with terrible GPS accuracy for months. GoogleMaps, Apple maps are both seeing the same issues. Inaccurate, sluggish and sometimes I'm forced to pull off the road while I wait on the GPS to find its brain.
I've reset phone, network and other settings and I always have WIFI on. Mentioned to my wife this morning and she has been having the same issue. Googled the issue and found that Verizon seems to be the problem. Low and behold, there are posts all over the Verizon community about this same issue.
Given that I'm not that happy with Verizon's coverage in and around zip code 76446, it is probably time to switch back to AT&T. Before I do that, I wanted to give Verizon a chance to fix this. It will cost me $90 to buy out the balance on my phone and I'll do that if I have to but won't stay with Verizon if they can't get this fixed.
