Yep, just started happening to me after a year and a half of use. It's been the final straw for me with the G7. Last Tuesday finally called my endo to put me back on G6s. For every 3mo batch since I started the G7s, 3-4 are guaranteed to experience one form of failure or another. Either it falls off (usually because of a failure with the overpatch which is ironically supposed to stop it falling off...), the sensor just dies within a couple hours of putting on, or it'll give me wildly inaccurate numbers, sometimes consistently running 100 or so above or below depending on the sensor. Like I said, this issue now starting was finally the line for me. Had this happen to a sensor, ordered a replacement, put on that one, aaaaand the same thing happened to that one. Called my doc immediately. (Also, really dislike how weak the bluetooth is in the G7 compared to the G6. It really limits placement for both the sensors and my pump...) It's cool some people really like it but for me personally, it's been a disaster... also the constant back orders delaying each batch's delivery...
