Certainly, very annoying. The one mitigation is that when the app isn't misbehaving G7 sensors are extremely accurate for me.
I'm not aware of anyone else using G7 on an android phone. I've also only been using G7 for months. I tried it (self-funding) for a month back in Apr / May, found that instantly better and committed to a quarterly contract.
Saw my Endo in August; mentioned how good G7 was and how I'd no prior sense of how wearisome and stressful it had been having to fp 4 x daily alongside wearing a CGM - just because neither Libre nor Dex One were accurate enough to trust even in mid range. An offer was made to see if I could have G6 or G7 on prescription from the Hospital; G6 was already supported by the Hospital but G7 wasn't at that time. My preference was for G7 since I liked the 10 day all-in-one sensor and transmitter rather than the 90 day transmitter with 10 day sensors for G6, but would take either if that ended self-funding. Heard nothing for a while, made a note to follow-up at end of November and out of the blue in late Nov a Hospital admin letter arrived telling me that my application had been approved and G7 would arrive soon. Which it did and I am extremely grateful to the Endo who'd put my application forward, from a face to face consult (no written paperwork from me) and to the Hospital in Oxford picking this cost up for me formerly in Bucks, now in Berks.
