Android is used worldwide and even the lowliest developer can write programs for it. What's the deal with the outdated hardware support? I hope the next version of the system is more inclusive. Weirdly I started a Dexcom app on my phone and didn't get the dreaded message for once. it began to set up my sensor and pair..... I was afraid to continue cause maybe it needed a new sensor which I didn't want to do yet. Now the message is back. So disappointing!
