Arrow symbol showing on lock screen

Hello nadir192, 

Thanks for reaching out to the Apple Support Communities!  From the screenshot you provided, I understand that this icon is only appearing on the Lock screen of your iPhone. 

I see no one has responded to your post yet. Here are a couple of things that might help others answer your question:

1 - You mentioned that this is only appearing on the Lock screen. What app were you last using before locking your iPhone? Do you have any apps running in the background on your iPhone?

2 - What is the iOS version number that your iPhone is running at this time? You can find it by going to Settings > General > About > Version. 

3 - How long has this icon been appearing on the Lock screen?

All the best!
