Can you elaborate on what you mean by your screen keeps shaking a couple of days?
Do you experience the same symptoms when your device is booted in safe mode?
Let's try putting the device in Safe mode to determine if there are external factors that cause this symptom. This step will temporarily disable all your third-party apps, but none of your personal data will be deleted. Your customization settings (Wallpaper, Themes, et cetera) will be reset to default once you exit this mode.
Please follow the steps below:
1. Turn the device off.
2. Press and hold the Power key past the model name screen.
3. When "SAMSUNG" appears on the screen, release the Power key.
4. Immediately after releasing the Power key, press and hold the Volume down key.
5. Continue to hold the Volume down key until the device finishes restarting.
6. Safe mode will display in the bottom left corner of the screen.
7. Release the Volume down key when you see Safe Mode.
I have what I believe is the same issue. Every few days mine will act up. It seems to happen when I'm using maps or YouTube. If I go to change screens or close either app my phone acts up. Typically the icons on the screen will start shaking similar to on an iPhone while removing an app. YouTube or maps completely disappears from the screen or drop down although I can still hear it. The phone will still function but very limited.
I also noticed this a few weeks back. I believe there were a couple updates recently with one of them being around the time this began. It's really annoying especially while using maps. The only thing that corrects it is a reboot only to appear days later.
