    My 950 XL worked pretty well from day one -got it the day before Thanksgiving via pre-order. A week or two later, I got a 128 GB SD card (SanDisk) and everything went downhill. Even just having the SD card seemed to cause reboots when it wasn't being accessed. I ordered a 128 GB Samsung SD card, no improvement. The biggest was the camera. I couldn't take or view pics without a reboot (or three). After having many Christmas moments ruined by this, I decided to wait for the next firmware before considering changing phones. As of last night, I hard reset the phone with the available software -rolling it back off of the insider .36 build. It picked up the firmware and the .29 update right away. I did not have to reformat the card or anything, it has simply worked since getting the update. I was able to sync all of my Groove music to the SD card (10 GB), I can take and view all the photos and videos I want -all are set to the SD card and not a single reboot. My phone is finally what I needed it to be. Thank you Microsoft.

    I had similar experience as you, but I won't say thank you to MS. Maybe MS should say sorry to me.

    sd cards are always the source of instability and performance drop so i don't use them.

    Always? That's definitely not true. The OS has bugs that cause instability as well.

    Very similar story except that I had a 128 GB SanDisk card in my phone from the get go and experienced very frequent reboots. I'm an insider and (for the third time) used WDRT to roll back my phone. Picked up the new firmware and then rejoined the insider program so I'm running the .36 OS and the .27 firmware. Phone now seems very stable and I can load up the SD card without worrying about crashing my phone. Now maybe I can start loving my phone :)

    after you installed the firmware how many times did It restart due to SIM changes? mind did it twice and righ tbefore the last one when I was trying to make a call it restarted. then I got the prompt to restart. still have Bluetooth issues where it drops connection then reconnects. going to wait until the next OS update (on .29) to see if that helps before I exchange it. plus they still have no stock in the MS stores near me so cant exchange it if I wanted to anyway. lets hope they get all these things worked out.

    I wonder what the delay is with getting them in store. I doubt the demand has been huge on these. im trying to figure out if its a hardware issue or software issue...

    My 950 xl has always behaved with my SanDisk 128 ultra. I have 87 gigs of music on it that I play all day via Bluetooth to my JamBox. I am on .36 os with .17 firmware in south florida.

    I have not experienced reboots since I did a hard reset from .29 to get to .36. (btw, I installed the sd card after that hard reset).

    I like the idea of having the latest firmware, but as my phone is quite stable, (and has been for nearly a month now), I will hold off until the firmware is available ota.........if it ain't broke, don't fix...............

    read / write speeds of sd cards are significantly lower than internal storage so inserting sd card into a phone will hinder it's performance. and there are so many different types / brands / formats of sd cards and sometimes they cause stability issues.

    THIS. I've had rare occasions of reboots but it's really not big enough a deal for me to hard reset my phone. Although I'm also kinda bugged out that we can't get the firmware update, at this point I don't mind waiting. Hard reset is going to be a lot of hassle since I've set up literally everything already since late November.

    So it depends on what you store on the SD. I store everything BUT apps. Maps, music, documents, videos, but not apps. So I can swap easily the SD card from a Lumia to the other, and no performance cost for apps.

    that's ok but I am used to rely on cloud services so I don't need to store much things locally...

    I have had zero issues with my 64g pro Samsung SD card, and I install everything on it. I had issues with a SanDisk SD card on my 640 with early builds of Windows 10, and switched to Samsung to see if it would help, and it did seam to work better. But on my 950XL, I have not had any SD glitches. I am still on the older firmware.

    I have a 128 Gb SanDisk and I got a few messages in earlier builds about the SD card being corrupted. I just ignored them and everything worked fine. I haven't seen a message like that in at least the last three builds
