Same issue - after upgrade to android 9, stock camera takes very long time to save vidoes to sd card.
i installed open camera app instead and its a good workaround for now. (it save on sd card very fast)

It looks fast, but sometimes it's not actually saving it. Create a lot of files (for example, take many photos) and try to delete them with the native file manager in Android. You'll see that it's fast, but when you check it afterwards you'll find that these files weren't actually deleted. Like with the Pocophone, it seems something went wrong with the external card management. I wouldn't recommend anyone to upgrade since this is beyond an annoyance, it's major (it can lead to data loss).

Try to format the sd card while it's inserted in phone. Backup all data before that.

The card is fine, I extensively checked it on a Linux PC. I started by running fsck for exFAT (it can't fix, but it can detect errors) and I carried out other read/write tests. I'll try to grab a Win10 PC to run chkdsk and see if there's any problem in the exFAT file system, but initially there isn't any. It started right after the upgrade, in the first reboot I already saw the "checking card" message. It was also working perfectly fine right before, just minutes before I downloaded the upgrade, several GB backed up on the card in a normal amount of time and I rebooted afterwards to upgrade on a clean system, seeing no message and observing no delay. Bear in mind that while mobiles aren't any speciality, I'm a sysadmin mainly specialised in enterprise backup&recovery, consumer storage devices aren't unfamiliar to me despite its differences and I take precautions beyond normal users, I also can troubleshoot in more extensive ways. This isn't hardware. This is a problem at the OS level, but I can't say where, because I'm clueless about Android innards.

This guy started using another file manager and it worked out.

https://c.mi.com/thread-2211076-1-0.html

It was my first attempt, I actually use the native Android file manager: https://play.google.com/store/apps/details?id=net.konos.createshortcut
However, as I described above, the operation looks fast. In reality it isn't. It's as slow as with the Xiaomi File Manager. Example: take 20 photos. Delete them all at once with the Android file manager. It looks fine. But then go to the Xiaomi File Manager. Some of the files are still there. That's why it's
not a file manager issue or a hardware issue. It's an OS-level issue.

Oreo does work fine with exFAT, Beta Pie did not support exFAT, right? Does Stable Pie support exFAT file System?

Suggestion:

I'll review if Pie supports exFAT, but it should (like, come on!).

Of course it should.
I did not upgrade to Pie yet just because Oero runs smoothly and i like to use files larger than 4GB in my SD.
I was waiting for feedback and it seems i did the right thing, PIE does not Support exFAT.

No, I didn't try and I won't because it's an ancient format by now and I'm not willing to format a perfectly healthy storage and run into other issues ;-) Stay with Oreo until the next update when they'll probably fix the bug (I'm definitely reporting it). From what I read it might just be a missing module in the kernel.

Second space issue, the SD card is invisible when following the actions (which involve using the standard Android file manager).

man! this is awful. I've been having major issues with audios from whatsapp, and notifications from whatsapp and emails, problems with led lights and didn't test camera yet. Some friends recommend me to go to Beta...someone did try?

The beta program is ending, so don't try.
I noticed that many of my apps' settings and permissions changed. The notifications I miss are probably related to the adaptive battery that I activated. For example, the Play Store doesn't notify me about available updates, however I have no problems with the email client, which I set up to never have battery restrictions. Such issues are to be expected with a major OS upgrade. However, the SD card issue is the big deal here, it's what slows down the phone. It's not a problem for those not actively using it, though. Otherwise, I see the upgrade as positive.

Workaround for the Camera slowness: in the SD card you have your /DCIM/Camera directory (folder). Rename that Camera folder to something else (for example, Camera_old). The next time you start Camera a new folder will be created and the app will be as snappy as before, switching between photo and video modes without a hassle. I took more photos than what I had before and Camera still went fast, even after stopping it, so the number of files per directory can be discarded as a problem. It's not a solution, though: when deleting those photos and videos it was still quite slow. I'm trying other ideas based on some system apps' permissions and reading dev documentation.

Apparently using FAT32 won't resolve the issue: Storage problem  http://c.mi.com/thread-2228686-1-0.html

I haven't checked this topic in a while, but today I noticed that it's getting weirder: local backups as after the Pie upgrade aren't being saved in the SD card. They're being saved in the internal storage, making them pointless in case you need to restore your phones data. This is upsetting me now, resiliency issues are something I can't tolerate :-/ I couldn't find any setting to force the destination.
