Samsung Galaxy s21 Ultra Canada Telus edition.

Yesterday, I rebooted my phone for the first time in a week and it gave me the "optimizing apps" screen for 10 seconds even though I didn't receive any new updates. It has never done that before. Needless to say, I have an issue that wasn't there two days ago. The front facing camera shakes so much, it's unusable. Selfie cam is fine. Downloading other cameras gives same issue. When I mean shaking, I mean:

Trees video was done from inside, I thought it was locked onto things that were shaking until I tried it by pointing it at stuff that was holding still.


As you can see, with or without steady cam on it shakes violently and with steady cam on it goes so dark, it's unusable. Any guesses how to fix as you cannot revert the camera and it affects all cameras?


In Canada on Telus using

Build SP1A.210812.016.G998WVLU5CVDC

Android security patch May 1, 2022 (which makes for the apps optimizing to be unusual)

You'll always see "optimizing apps" after an update, or occasionally after Reboot, it's normal.

As for the shaking, Switch to green tea instead of coffee lol, sorry I couldn't resist.

But seriously now there's a few things that you can try.

Boot into Recovery & Wipe Cache.

Open the Camera & it's Settings & Reset the Camera Settings.

Go to Settings > Apps go the Camera & Scroll down it's Storage & Clear BOTH Cache & Data.

Reboot after the last 2 suggestions.

Hopefully one of these will fix the issue for you 🤞
