[Diabetes-Talk] Overview of my recent change from Dexcom G6 to G7 using an iPhone.

hi Paul.
Good overview of the Dexcom G7.
First, Dexcom is aware of the problem with the more button. That’s a real gotcha the first time you find it. Second, when you go look at your alarms, there is a setting that you can play with which determines when it gives you an alarm. You can set it to give you alarm for instance, if you’ve been high for at least a half an hour, or give you an alarm every time you go high. playing with this can cut down on the number of alarms you get as you hang around that high border. That drove me crazy too. I also agree with you about the difference in automatically announcing your number like the G6 did. And I kicked my clarity stuff out of that screen as well. for some reason, my last batch of sensors was really hard to scan for the QR code. I’ve had somewhere it happened instantly just as you described. But my last batch, I just couldn’t seem to get it to scan for my life. I really don’t know why and I’m going to try to find out. but I’m glad you are happy with it and I agree, I like the smaller size as well as the faster warm-up. I actually put my new sensor on before I take the old one off. Then when I change over, I have no warm-up time. That is really nice.
Thanks for sharing your experience.
Veronica.
