gps laggy

Hello eararche30,

It sounds like your navigation apps or gps is not precise.

Here are some resources that might help:

Your related article If Maps isn't working on your Apple device is a great one to follow. For additional information, see:

• Turn Location Services and GPS on or off on your iPhone, iPad, or iPod touch is helpful to ensure the correct services are turned on.  
• About privacy and Location Services in iOS and iPadOS.
• Ensure Settings > Cellular > [App Name] is turned on for the navigation apps you are using View or change cellular data settings on iPhone

As you say the apps are lagging, another resource that may help is About iOS performance on your iPhone, iPad, or iPod touch

Hope this information helps. 

Have a good day.
