No, Snapchat filters are mainly applied directly when taking a photo or video within the Snapchat app. You can't add photos from your camera roll and then apply Snapchat filters to them.
Sure! You can do that. Just look for the option within the app that enables you to select and upload from your camera roll. It's pretty straightforward once you find it.
It may be that they're still interested in your life to some extent. They might not be able to completely cut off that connection and seeing your stories gives them a little peek into your world.
Maybe they don't have Snapchat installed or their app is having issues. It could also be that they aren't on your friends list or you accidentally restricted their access.
It could be that your friends are just chatting with others a lot, which increases the score, but they're not posting stories. Maybe they prefer private conversations over sharing public stories.
Maybe there's a problem with your device settings or the app you're using. Check if you have given the necessary permissions for saving to the camera roll.
There are several possible reasons. It might be a glitch in the app, a problem with your device settings related to storage access, or even a software update that caused a temporary bug.
It might be that the people who viewed your story have enabled settings to remain anonymous. Or, there could be a glitch in the app that's causing the problem. Try restarting the app or checking for updates to see if that helps.
It could be that Snapchat wants to maintain a certain level of anonymity and freedom for its users. By not revealing who screenshots, it avoids creating unnecessary drama or pressure on people.
