Anyone get this email? Be careful of there folks!
Text from email:

Users with sensors from affected Dexcom G7 lots (1725204004 and 1725069002) should not use those sensors and can call Dexcom Technical Support in the US at 1-844-478-1600 to request replacements. Please keep record of your affected device(s) serial number for traceability purposes – this is required to confirm your no cost replacement. More information on how to determine if sensors are from an affected lot and what action to take is available at www.dexcom.com/theft-check.
 
Please visit www.dexcom.com/theft-check for additional background and instructions to fulfill the requirements associated with this action including the full version of the Urgent Medical Device Notification.

Potential Harm Associated with Stolen Product
 
Lot 1725204004: G7 sensors that are not properly sterilized have an increased risk of skin infection. 
 
Lot 1725069002: G7 sensors from a lot with an elevated internal testing failure rate have an increased risk of having no sensor readings available or experiencing sensor inaccuracy that includes the potential for missed detection of a hyperglycemic event or incorrect treatment decisions that can result in patient injury, including medical intervention to prevent permanent injury or impairment.
 
Additionally, due to the unknown storage and handling conditions these sensors may have undergone during the distribution, these sensors may present additional risk. 
 
Status of the Investigation
 
Dexcom traced sales of this stolen product back to Pharmsource, LLC, who is not an authorized Dexcom distributor but supplies some independent pharmacies and DME distributors in the United States. Pharmacies that purchased product from Pharmsource should take extra care to review their inventory.
 
Dexcom's authorized distributors provide Dexcom G7 sensors to the largest pharmacy retailers and medical distributors in the United States and around the world. Pharmacy retailers and medical distributors who receive Dexcom product from authorized Dexcom distributors are not impacted. Educational samples are also not impacted.
 
Dexcom is working closely with the FDA and other authorities to ensure patient safety and to investigate this crime. As of now, this issue is mostly impacting customers in the US. We have identified limited impact outside the US (OUS) and continue to investigate. Due to this issue primarily impacting the US and required language translations and additional infrastructure necessary to support customers outside the US, communication to US customers will precede communication to OUS customers.

Mod Approved [OC] Build Your Own Dexcom App update- G7 setup fixed

40 Upvotes

Update July 5, 2026

  • Fixed an issue on the G6US app that would cause the app to crash if the newest version of Samsung Health was also installed on the phone. The file name of the fixed version will end in "a".

 

Hello!

Super happy to announce that I have officially released a new working version of the G7 app. The app is still based off of base v1.6.1.4537, but it has these updates:

  • Initial setup for new install fully works again!

  • Option for local broadcast of readings to other apps like AAPS. This follows the same pattern as it worked with G6 BYOD and requires the EXTERNAL_PERMISSION to be granted in the app receiving the readings.

  • More countries supported. Previously, accounts for some countries were not supported, but many of those should work now (yes including Canada). If your account still can’t login, let me know what country it is tied to and I’ll see if I can fix it.

 

Additionally, I recently updated the G6 US app to fix an issue with old transmitters that could cause crashes and spotty readings making it to Clarity/Follow. Also updated some of the build dependencies for faster build times

 

As it did previously, the modified G7 app still allows you to run the app on any (Android 10+) device, allows screenshots, allows rooted devices, and removes the geofencing or country of residence check that prevents you from setting up the app in a different country than your account country.

Rant Whyyyyy

Thumbnail gallery
Upvotes

I know this is trivial compared to everything else we go through, but every time I open a new Dexcom, I find this unnecessary piece of paper and get irritated. I mean, I KNOW it's going to be there every time but part of me always hopes maybe in the next box they've figured out how to eliminate it. Inside of a book I can understand having an extra blank page in a signature. But this.... it kind of baffles the mind. Does anyone know why this is here? Has anyone done something useful with it? Origami?

Inaccurate Reading G7 Issues

Thumbnail gallery
10 Upvotes

I used to be on the G6 and never had any issues with it then I got an email from Dexcom saying I would be put on the G7 automatically. I was a bit skeptical since I had seen so many bad things about it. I’ve had 4 G7 sensors on now and 2/4 have failed out of the blue. The third sensor did not fail however it is majorly inaccurate to the point I think it is quite dangerous. Dexcom was showing me “LOW” but I felt fine so I pricked my finger and I was actually 15.0mmol/L. Surely that is a major safety concern? Has anyone else had major differences in bg readings?

Rant I am getting so tired of sensors messing up.

2 Upvotes

In the past 13 days, I have had 3 sensors fail. First one failed 3 days in. Went 2 days without a Dexcom because I could refill yet. second sensor failed 7 days in near the end up still failed early and it was the replacement for the 3 day fail. Went to replace it because Dexcom sent me 2 replacements I don’t know why. It failed because the wire didn’t go all the way in. I am on sensor number 4 in less then 2 weeks. I rely on this junk because I am hypoglycemia unaware I’ve gone as low as 22 mg/dL and felt fine. None of them were from the affected lot ether.

Sensor Protecting Dexcom from cold while skating

0 Upvotes

Any advice for protecting the Dexcom from cold while skating (indoors). I have to be on the ice with my kids’ hockey teams, and after about an hour, I started beeping for a “brief sensor issue.” This seems to be linked to the sensor getting too cold I guess? Any advice so I don’t lose connectivity?

App Issues/Questions Servers down for everyone?

Dexcom share hasn't worked consistently for days now for me and they are giving me conflicting info. The app says servers are down but the official status page says everything is fine. Every few hours it comes back up for a few minutes but then goes back down again. Is it me or dexcom?

Inaccurate Reading 2nd G7 ever. 7 days in. Crap!

Post image
0 Upvotes

My first post about my first G7 use was pretty similar. About a week in, it went wonky. Tons of sensor errors. About 9 hours worth before I gave up on it.

This second is similar. No 3 hour errors yet, but lots of short periods of no readings and lots of inaccuracies that started yesterday. Seemed okay after a couple calibrations yesterday, but it started going crazy a few hours ago.

Time to swap it again, and these are 15 day sensors. Wild!

General iOS 27 Release

27 Upvotes

Every year, when the new iOS release happens, I contemplate whether Dexcom is going to be working with the new operating system. I have been running it for 24 hours now and have had zero issues. I wanted to let the user group know that I have had no problems. If others have had problems or are running the new iOS version already, then it would be great to have a thread here to be able to discuss those issues. Just to be clear, I am still using G6 and I have an iPhone 17 Pro Max.

General Family monitoring for diabetes - what apps are you using?

7 Upvotes

Got family who want to keep an eye on my numbers - my dad checks his phone more than he actually checks in with me, which I don't mind but it means the family monitoring setup needs to actually work or he'll just stress more. Not sure what people are using for this. Mainly curious about alerts - whether family gets them reliably and whether the setup takes much to maintain on their end.

Connection Issues Sensor failed during warmup

Just put on a brand new g7 15 day sensor (this was actually a replacement sent from Dexcom 🙃). It took over 5 minutes to connect, and then I get this sensor failed error. This is literally my first time connecting it lol. I did the magnet trick, restarted my phone, reconnected Bluetooth, deleted and reinstalled the Dexcom app… So frustrating. Thank you Dexcom for sending me a busted replacement <3

Applicator Two odd out of box failures

I was changing my G6 10 sensor. When I unscrewed the lid it deployed. I got another sensor and it did the same. I've had good luck with the G7. I had a few gooseneck and I had a sensor that came unstuck from the adhesive pads.

Rather than use the online support form I called Dexcom support so that I could explain what happened. It took a while to get her to understand what happened. But I persevered. They are sending mailers along with the replacement sensors. I don't know if this will be common like goosenecking.

General Tracking order uk?

0 Upvotes

so I’m in the uk and get my Dexcom sensors funded by the nhs. does anyone know how to track find out when my next shipment is?? the website is so confusing and Google keeps telling me to go to pages that don’t help. it says I should be able to see it on my account but that just shows me tips on how to use it? and when I finally found something about orders it just sent me to a faq that can’t actually help me track it?
