Galaxy S6 :: Improve Location Accuracy Popup Dialog

There are 3 location settings,

1. GPS, Wi-Fi and mobile networks - this lets Google use any of these to find your location even if Wi-Fi or location is turned off. When this is switched on, you'll often find Google Play Services is one of the biggest issues.

2. Wi-Fi and mobile networks - this disables the GPS chip inside your Galaxy S6 Edge and is probably the least useful of the three options. Relying on just mobile networks and Wi-Fi will allow you to find your location quickly but will then use a lot of data and battery as it relies on your Wi-Fi and mobile networks to keep track of your location.

3. GPS only - this is actually the mode I use as it prevents Google scanning in the background (more on that below). It has its pitfalls in that it can take a while to find your location but the battery savings from not having Google scanning are plentiful.

We know that option 1 and 2 could lead to extreme battery drain because Google uses the location manager and wake up the device. When you attempt to turn on either the first or the second option, you're greeted with a prompt from Google to "Improve location accuracy". The option means that anonymous location data can sporadically be sent to Google even when no apps are running, and as a result, this can have a large impact on your battery life, especially when using Google Now or widgets that depend on location. If I choose one of these options I do not see the dialog anymore. Maybe I accidentally clicked "don' t show again".

How can I get the dialog back? When I enable the locations, it is always set to option 1, even if I had 3 the last time.
