I have a tablet dedicated to this. It is old. But perfect for this.
We are now on the Dexcom G6 cgm however this worked just the same on the G5.
Samsung Galaxy Tab 3
Runs Android 4.4.2
Pretty cheap on eBay
Dexcom Follow App 18.104.22.168
App Last Updated: October 2016
First I had to enable “Developer Options”.
I did this a long time ago so I don’t recall. But it was very weird like how to find an Easter Egg in a program. I just tried to look it up and found this (which sounds odd but also sounds familiar):
To enable Developer Options, go to About phone in the device’s Settings, then tap Build number seven times. Now, you can see and access the Developer options menu from the device’s Settings.
Once “Developer Options” are enabled, then go:
Settings ==> System ==> Developer options ==> Stay awake
(Screen will never sleep while charging)
Plug the tablet in on your nightstand, prop it open and it runs all night.
Roll over at night and you can simply glance at the tablet to see the graph. It never times out while plugged in. No screen saver. No time out. Nothing. It will stay on the Dexcom cgm graph forever. Note that I don’t get the typical audio alerts so I am not sure if I broke something but I can hear the audio alerts from the next room anyway so that doesn’t matter in my situation.
