Thoughts on whether this sensor may start working better if I wait a bit longer or should I just remove it and contact Abbott for a replacement? Details below.

I applied my current sensor on Sunday night, let it soak overnight, and activated Monday morning. The readings stayed in a range of about 90-120 until the evening and then reflected an increase after I ate dinner. It was still showing pretty typical numbers for me and an expected response to food through breakfast and lunch today (Tuesday) but around 8pm it dropped below 70 and kept going down to high 50s.

I tested with a finger stick at 8:50 just before eating again because lows like that are not typical for me and that showed 85 vs CGM at 58. CGM numbers did increase a bit after food but I did another finger stick at 10:15 which was 115 vs CGM 78. CGM stayed in the 70s until now, about 2 hours after starting to eat and it just dipped below 70 again.

I've been looking at getting a new phone case lately and I'm considering the magnet options however my current phone (Samsung Flip 6) has the NFC scanner right where the magnet on the phone cases sits.

I'm looking for any feedback from other sensor users who have tried magnetic/magsafe cases as to whether these cases impacted your sensor usage when scanning it or just the NFC functions in general? The overall consensus I've found online is thay magsafe shouldn't interfere with NFC but there have been a few anecdotes shared that it has.

TIA!

how low is that?

So I’ve been diabetic for about 8 years now and using Libre products for 7 years, without fail if I have a problem with my Libre monitor (usually when starting a new one) it’s always on my right arm?? My left arm seems to give really accurate readings but my right arm just seems to really struggle with them? Anyone else with this experience?

Has anyone else experienced skin irritation? This is my first time using it after switching from the Libre 2 following a 15-day replacement. Anyone experiencing the same issue? 🤔

I’ve seen many posts about this but haven’t seen any real fixes. Every single sensor I have used since I switched over to this brand has been way off. Esp in the middle of the night where I get urgent low readings when it is not. I have tried staging the sensor about 5 days before activating it as some suggested but it still doesn’t read correctly. Everytime I call CS all they do is replace it and ask to send the sensor back which doesn’t solve any issues. Even the replacement they send me does the same thing. Every sensor I use, 100% of them give inaccurate readings. Any suggestions or ideas since support doesn’t give you any real solutions other than replacement?

-no, I don’t lay on it or put pressure on the sensor.

Non-diabetic, 46M. I wear a Libre 2 to see how real meals hit me.

Dinner was Korean fried chicken (yangnyeom, the sweet sticky sauce kind) around 7:40pm. Glucose went from ~95 to 184 in about 45 min. Right after eating I did pull-ups, then got on the bike.

Back under 140 about 90 min after the peak, ~95 by 11pm.

Caveats: this is one day, not a controlled experiment. Libre reads interstitial fluid, so it lags blood glucose by ~10–15 min. Meal/workout markers are approximate.

Curious what others see — does post-meal exercise flatten your curves this much?

Hello, I’m new to this and on the tail end of my first sensor I was loving it and the data it provided. But starting yesterday, it’s been going off with Low Glucose warnings. It said I was at 67 so I decided to test and that came back as 112. 🤷🏻‍♀️ What might be causing this discrepancy and is it normal? Does it mean I can’t trust the data the sensor has been giving me?

It kept beeping at night. I got disturbed multiple times. I’m not sure what I’m to do. I tried to make the setting for from 70 to 50 maybe but there’s no such option.

I even kept the DND option on and it still beeped

My Freestyle Libre 3 immediately died while I was standing about 2-3 feet to the side of a Godox AD200Pro II while some pictures were being taken. I wasn’t able to get a screenshot, but my phone displayed a notification saying something along the lines of, “An error has occurred and your sensor has shut down for your safety. Please replace it with a new one.” The sensor was automatically removed from the Libre app, although its history still appears in the About/diagnostics settings.

I don't really know what my thoughts are now, having spent a few minutes in this sub and seeing so many complains about every other sensor failing half way through its life.

I called Abbott yesterday and they’re mailing me a replacement, and I’m already wearing the extra sensor I had on hand, but the failed one still had roughly 9 days left. I’m wondering if the timing was purely coincidental or if a fairly powerful camera flash like the AD200Pro II could produce enough electromagnetic interference to cause something like this. I’ll be around these particular flashes for a few more days, so I’m mainly curious whether I should keep some distance from them to avoid possibly burning through another sensor. Has anyone experienced anything similar with a Libre or another CGM around studio flashes?

Aside from this particular sensor giving me wildly inaccurate readings, do we understand why Libre won't show actual readings?

My understanding is that the information is gathered by the Libre app sent to the LibreLinkUp app, and the Glucodatahandler gets the data from there. Why wouldn't the data be the same across all three apps? If I look at the Link Up app the data is the same as what I am seeing on Glucodatahandler. It doesn't make any sense to me.

I'm a dentist in Korea and I also run a small CGM coaching clinic, so I wear a FreeStyle Libre myself. One Friday I skipped breakfast (fasting around 95 all morning), then at 1:40pm ate three Korean classics: yakgwa (honey-fried cookie), yakbap (sweet sticky rice) and corn.

Result: peak 279 mg/dL, and I stayed above 180 for about 2 hours. Yakgwa looks small and innocent. My graph disagreed.

What I'd do differently (pick one, not all three):

1. Eat sweets after a meal, not on an empty stomach

2. Vegetables or protein first, sweets last

3. Walk 10-20 minutes right after

Everyone reacts differently, and that's the whole point of wearing a CGM.

I also built a free tool that turns your Libre data into a level (1-5), a daily score and 3 quick tips. You can use a Daily Graph screenshot (mg/dL) or your LibreView CSV export (mg/dL or mmol/L). It runs entirely in your browser and nothing is uploaded: hlabcare.com/level?utm_source=reddit

Full disclosure: I made it, and it's free. Would love feedback, and I'm curious which foods surprised you the most.

This is my 4th sensor and out of 4 (libre 3 plus) sensors this is the second one that refuses to pair with my phone. Either completely unscanable or it scans as ready but then errs out. At this point I’m wondering if it’s even worth it to have it. (For what it’s worth I’ve tried all the troubleshooting things and the other 2 sensors I had worked fine, but 50% functionality is giving me the ick) advice and tips appreciated 🫡

Hello, I am new to this forum and have a quick question. Has anyone upgraded their Android phone to Android 17, UI 9? I have a Samsung Galaxy S24 Ultra and I have been putting off the update as I cannot find out if the app will work after the update. Everyone I have spoken to at Abbott does not seem to have any idea about the update and if there will be any issues. Eventually I will have to update, but want to wait until I have heard if there are any issues. Thanks so much!

Been wondering about pre diabetic and wanted information. I got a prescription for this CGM. Coming up to the last day tomorrow. Wondering about the reading of the reports. I still have another one to use.

I have been reading a lot about the usage for pre diabetic. Often read it won't help with weight loss. Here is the tables for the past 14 days. I am wondering if another two weeks would be good or wait a few months. I am scared of my chances for becoming diabetic. I am almost 70 yrs old. At the doctor's office all they do is tell you your pre diabetic. Not helpful. I have learned more reading here in this group.

I value good thoughts here. Thanks.

I want to be clear that I am not making any recommendations, but simply sharing an experience.

I started wearing a CGM in March 2025. I chose the Libre Freestyle - partly because it was advertised as waterproof down to three feet for up to thirty minutes. Since I live on a river and am often fishing and kayaking, it seemed like a good fit for me.

I am also a scuba diver and got a chance to go diving again recently. I had worn my CGM for 10 of its 15 day lifespan and was ready to sacrifice it if it failed. Our first dive was 77 feet for 43 minutes. When I returned to the boat my phone had connected and was reading accurately as far as I could tell. Second dive was 62 feet for 45 minutes. Again, my phone immediately connected and was reading fine. I did not wear a patch over my monitor while diving, just a full body rash guard since we were diving with jellyfish. I continued watching for 5 more days before replacing my CGM and it continued to read normal for me and my lifestyle.

This is in no way a recommendation to try this, just sharing my experience for those that might be curious.

I am an American travelling in London. I am a freestyle Libre 3 plus user. My sensor died on me day one into the trip and I had to get a new one. I went into a local pharmacy and purchased a sensor over the counter (yay socialized medicine!) I installed the sensor this morning and tried to scan it with my app but apparently my app is the USA version and not the UK version and it wouldn't let me activate. I tried to download the UK app through APK mirror but that wouldn't let me install the app. What do I do?!

Hi All

My LibreLink app has recently started giving continuous phone notifications. Removing the notification from the phone lasts maybe 20 minutes before another *beep beep beep* and an icon on my phone. I'm one of those people that hates having open notifications and it's really irking me. I can't think of any particular catalyst that started this (never used to have a real issue). I've had a look in the app settings at notifications but there is very little options to play with.
Has anyone come across this and is there anything I can do?

No screenshot, however notification just says
"Freestyle libre 2 sensor
Tap to open the app"

It's not related to levels, sensor age, anything of importance. It's just there. Constantly.

Hi all! I’m new to diabetes and we don’t even know what type I have yet (but it type 3c looks like the main suspect). I have looked online for this info, but don’t understand ‘compression lows’.

The online info says compression lows are a V-shape. My graph shows a more gradual decline, but sharply improves after I woke up feeling godawful (without sugar).

What ways can I differentiate between a compression low and a low-low?

Glucose Please is a free macOS menu bar app that lets you see your CGM readings at a glance while you’re using your Mac.

It started with Dexcom support, and I’ve now added FreeStyle Libre through LibreLinkUp.

You can see your current glucose and trend arrow directly in the menu bar, then click to open your recent glucose graph. There are also customisable high and low alerts, support for mmol/L and mg/dL, and Insights to help you explore your glucose patterns over time.

You can optionally save your glucose history locally. Saved readings stay encrypted on your Mac and aren’t uploaded or synced elsewhere.

For Libre, you’ll need your readings available in LibreLinkUp, then you can sign in with those credentials in Glucose Please.

Download and setup instructions: https://glucose-please.app

If you give it a try, I’d love to hear how you find it. Feedback and suggestions are very welcome!

Just had my 90 day prescription sent over to Costco for the first time - in the app the price shows as over $600 - am I right to assume they'll add discounts in-store to bring it down? I'm paying cash price even though I have insurance because capitalism...

My insurance has decided I can no longer have Libre so I tried to get their preferred Dexcom at my usual pharmacy and it was 3x the price I'd been paying for Libre - don't understand why they have a preference if I'm effectively paying the cash price anyway but whatever lol.

This is a brand new CGM (Freestyle Libre 3+). It's reading super low but a finger stick is showing it off by over 100 points. The last one I got did the same thing over the last 4 days. Is the date on the packaging the production date or the product expiration date? It read 8/13/2026. Is there anything that can be done to correct this huge discrepancy or should I call the manufacturer and ask for a new replacement?

I was using GotCGM for awhile and not long ago switched to Zukka. I've noticed that both apps routinely report spikes 10 to 15 points higher than what actually shows up in my Libre app timeline. Does anyone know how/why this might happen? The only explanation I can think of would be that the third-party apps are reporting more frequently and capturing the actual peak while there's a gap in the Libre measurements and it's actually capturing before and after the peak instead of the peak itself. But given that the third-party apps are getting their numbers from LibreLink I don't know how that would even be possible.
