1. Try "Reboot system now" (Most common and safest first step):
○ Use the volume keys to navigate to this option if it's not already highlighted, and then press the power button to select it.
○ This will attempt to restart your phone normally. If it was just a temporary glitch, this might fix it.
If "Reboot system now" doesn't work or it keeps coming back to this screen, here are other options to consider, but proceed with caution:
2. "Wipe cache partition":
○ This option clears temporary system files without deleting your personal data. Sometimes corrupted cache files can cause issues.
○Navigate to "Wipe cache partition" using the volume keys and select it with the power button.
○ After it's done, select "Reboot system now."

I have tried it but it still does the same and go back.

It's very rare nowadays for a Samsung device to do that on its own if your device is running an official firmware... I'm not sure if you had a rooted device or not. That problem is most common with Transsion Mobile devices (Tecno, Infinix, and Itel.)
If you tried all the other suggestions by the other mates here, maybe there could be a problem with the Vol + button on your device. Or you probably need to get it rewritten with a new firmware.

How do i do that ?

[MrDee]

You should take it to a repair shop. They will have it fixed for you safely.
I can give you the guidelines here, but if you are not into electronics repair, it will still be difficult for you to do it by yourself.

Ok i guess

Navigate to power off using volume keys, then use side button to select.... the device should turn off then you then power it on normally

The main question is did you open recovery mode or what happened for it to end up here

[SeanShakes86]

I didn't open it it just went like this while i was using it.
