This is kind of a long post and I provide a detailed experience with the phone and Tmobile store representatives so if you want the short version of this post, just read this: I've had problems with both the LG G Stylo and the LG G Stylo 2 Plus with the GPS--it doesn't update when you're driving and before you know, you've missed your exit by 5 miles!
I originally had the G Stylo and saw that the phone had plenty of other users with the same problem as me--GPS wasn't working often. Some solutions were given--Google. But ultimately none of them worked for me. Now my sister ended up needing another phone and I was wanting to get a new phone so I gave her the G Stylo. When that phone just stopped working, the screen just didn't turn on, she decided to get another phone. She liked the previous phone and decided to get the newer model, the LG G Stylo 2 Plus. Within 2 weeks, the gps problem came up again. My sister and I go to the tmobile store and tell them about the problem, they suggest a factory reset and told us that if we were Pokémon Go users and enabled developer options to create a false gps location, that will mess up the GPS. To enable developer options, required some know-how and touching a menu option 7 times--I certainly didn't know that but the direction was to do a factory reset and make sure that the mock gps was turned off so I had to look it up on how to even make sure that it was turned off.
The solutions given to us to bypass the problems were laughable. One person said that it may be app related--the Google Maps app could be at fault and using Waze is just as good and if the GPS problem really is an issue, just remember the directions by looking at it. So, I didn't know that some phones require only some apps to be used in order for a gps to be functional.
I think the store located at the Tustin Marketplace just doesn't want to handle returns or they get docked for accepting too many returns. Case in point: when my sister tried to return cell phone towers that help signal in locations that aren't very good, she was turned away at the Tustin Marketplace location and was told that that needs to be handled online or over the phone. Baloney! She does it online and she gets a prepaid label with instructions that she could return it at a Tmobile verified store or mail it back.
Anyways back to the phone. After the factory reset, I decided to test it and once again the gps signal "was lost" according to the Google Maps app. All in all, this could be isolated to a very few select LG G Stylo 2 Plus devices but I do find it odd that this problem popped up with two versions of the same model. Mind you, I've owned several Androids like the LG G3 and the Moto X Pure and none of them ever had GPS problems.
Anybody else with this problem?
Update: my sister didn't want to argue with Tmobile again so she's just going to tough it out with the phone despite it being erratic with the GPS.
