Same problem here, though not a big issue for me since this is not affecting performance and usage.

Also I have 4 things queued in Store download and updates with error 0x803F8001, these 4 things are display, audio, rate us, touch. Is it ok to just ignore this? Can't update them since 2 days ago.

I see a lot of ppl suffering from excruciatingly slow update from 10512 to this new build, I suggest roll back to 8.1 (if possible) and update directly, since it only took me only about 1 hour to complete it from 8.1 to 10536.1004

Just checked my Battery Saver and saw Photos and Store both using over 10% battery running in background, wow! I'm gonna try disable them running in background to see if it improves battery life.

Here's more:

Build 10549 is released for Fast Ring

Windows Insider head Gabriel Aul posted the list of the fixed problems in build 10549:

-The Windows Camera app no longer crashes when certain applications launch it to capture a picture.
-We fixed an issue where the touch keyboard would get dismissed every time you sent a message, which made sending 2+ texts in quick succession difficult.
-We fixed an issue where swiping away a notification was causing the notification icon to appear top of your screen.
-Screenshots were not being properly saved resulting in many top social messenger apps such as WeChat, WhatsApp, LINE, WeiBo, and QQ unable to find saved screenshots. This has been fixed.
-We fixed an issue where you couldn't cannot launch apps saved on SD cards after reinserting your SD card.
-Pinch to zoom should work properly in the Maps app now.
-We fixed an issue where trying to set a custom ring or text tone for a contact shows a black screen for 10 seconds, then does nothing.
-We have added back vibrate-only alarms.
-We have fixed call-blocking.

This new build can only be updated from 8.1, so if you are already on Windows 10 Mobile you will need to roll back first

There could be a new build which can updated from 10536 very soon according to Gabriel Aul

Heard 10572 overall performance is very good, as smooth as 8.1
I'm now on 10549, tonight roll back to 8.1 to update to 10572
