GRASS-GUIDE
Grass Guide is based on the Android mobile operating system, and to reduce the burden (and cost) of testing and supporting the very large number of available variants, we only support a small range of tablets, all of which to date have been Samsung.
If you need to replace your tablet, and want to buy it from a different supplier (which, of course, you may do) then make sure to check it is a supported model.
The model currently being shipped is the Samsung Galaxy Tab A7 Lite 32gb Wifi - known as SM-T220
Note that currently this model will only work with the new Novatel SMART2 GPS receiver.
For tablets compatible with the older Novatel AgStar receiver, the supported tablet is the Samsung Galaxy Tab A 8" known as SM-T290
When the Grass Guide system is shipped (or if you buy a replacement tablet from Sixty-5 Technologies), the app will be pre-installed and placed on the tablet home screen - a green icon with the numbers 65 on the front and Sixty-5 below.
It may be that the app has been moved off the home screen, in which case swipe up from the bottom of the home screen (or from the bottom left, depending on the tablet) to reveal all the apps installed on the tablet, and swipe left or right to reveal more if there are too many for a single screen).
If found, tap it to start the app as usual.
You may also move it to the home screen by pressing a holding your finger on the app icon (know as a long press) and then dragging it across screens to the home screen.
Search on Google for more detail on how to do this.
If the app isn't installed, then find the MyFiles app that comes with the tablet and open it. Look for the Downloads folder and in it you should see the original download of the app - it will have different names depending on variants etc, but will be something like: app-release.apk, GG4-v4.0.3-release.apk etc.
Tap on it and follow the instructions to install. You will then be prompted to re-register (see questions under App).
