Yeah I guess that's the only way to do it. I thought that there was some way to keep the maps permanently on the phone,that's the reason I'm researching
You know that you can just go into Google Maps menu and update expired maps? Per Google:
Offline areas that you downloaded on your phone or tablet need to be updated at least every 30 days. When your offline areas expire in 15 days or less, Google Maps will try to update the area automatically when you're connected to Wi-Fi.
If your offline areas aren’t automatically updated, you can update them by following the steps below.
From the notification
- In the "Update offline areas" notification, tap Update Now.
- Tap the expired or expiring area on the list.
- Tap Update.
- The offline area will update.
From anywhere else
- On your phone or tablet, open the Google Maps app
.
- In the top left, tap the Menu
Offline areas.
- Tap the expired or expiring area on the list.
- Tap Update.
- The offline area will update.
