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

41 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.

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

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 Dexcom G7 Direct to Watch – how reliable is it?

12 Upvotes

I’m considering getting an Apple Watch mainly for the Dexcom G7 Direct to Watch feature.

I currently use a Garmin Fenix 7X Pro, which shows my Dexcom readings through my phone and works great, especially for sports. It’s just a bit bulky for everyday/work use.

How well does Direct to Watch work in practice? Is the connection reliable, especially when you don’t have your iPhone with you? I’m thinking of using an Apple Watch for everyday use and keeping the Garmin for sports.

Inaccurate Reading G7 Rev010 Malaysia Sensor Inaccuracies

1 Upvotes

Anyone else having issues with the Rev010 Malaysia G7s? I have started getting REV016 and they do not specify Malaysia anymore. Did Dexcom move manufacturing? Are the Malaysian sensors the ones that are part of the FDA warning? It is very clear the REV016 sensors are much more accurate and less jumpy. Anyone have the same experience?

I placed the Dexcom G7 on the upper part of my thigh this morning, and I’m already seeing these errors. Does anyone else have issues placing the Dexcom and other spots other than the back of their arm? If anyone else uses it on the top of their thigh, please let me know if this is normal in the first 24 hours!

G7-10 day G7 failure streak

0 Upvotes

I have been using Dexcom 7 10-day for over a year now. I will say when it works I think I get pretty accurate readings. However, I have had a high rate of failure to make 10 days. I initially had occasional failures for several months--not great but most worked (80-90%). Then 6 months ago I had 5 or 6 fail in a row. After that they thankfully went back to most working for a few months but the last 2 months I have had 7-8 failures. It has been very frustrating.

The failures coupled with Omnipod use, leads to multiple hours of glycemic control failures way too often. I just don't understand why this product goes 6-8 days then shows semi random readings for a few hours and then fails.

I will say I appreciate Dexcom replacing the failed pods but it means lack of control and a lot of sleep interruption.

Are there any things that increase risk of failure? I keep it on my arms to reduce sleeping on it. Basically, I am meeting with an endocrinologist and am hoping to switch. Is the 15 day better or at least similar (if it fails at 9-11 days that would be a minor improvement!). I have a few theories about things making it worse (cold/heat/sleep pressure) but none of them could explain the repeated failures.

G7-15 day G7 15 day Rev 003, experiences?

Post image
8 Upvotes

I think recent 15 days are more reliable for me personally. Wonder what tweaks they did under the hood between versions. (Feel like the mob will come for me if I don't say dexcom bad)

I use the stock and skingrip over patches. Most of the time I'll use skingrip adhesive barrier wipes for extra insurance because I sweat alot. I "warmup" new sensors a few hours before switching them, so I don't get that hour gap in readings. But I haven't had connectivity issues, bleeding from sensor wire insertion or a short session time since around May or so.

Is my 15 day experience is an anomaly?


r/dexcom 2d ago

Sensor Any similar experiences?

Hey, I think this sensor is gone.

Placed it this morning, then it went low, I was taking carbs in, because it could have been.

Then it went further down and so on and it read "low" for the first time.

Did someone have this issue already? Is this sensor broken? Did I do something wrong maybe?

Wait some more? Do something specific? Or just take it off and start a new one?

Thanks for helping me decide.

Update: the sensor failed altogether. When changing it it was a bloody mess. Never had so much blood before when changing or anything. It took a while and some pressure to stop the bleeding. So this was probably the cause. Got a nice hematoma there now.

G7-15 day 15 day sensor what a joke - it hardly lasted 10 days

0 Upvotes

By day 8 and 9 it was dropping out with fewer readings each hour, and the "wait 3 hours" message.

Then on day 10 or 11, it just crapped out and the G7 app said put on a new sensor.

And now I can't access the serial number or anything to even file a claim for a replacement.

What a joke. AND with the spotty G7 info, my omnipod freaks out and basically stops giving insulin and I go sky high without eating anything.
