A quick screenshot feels harmless, but it puts a secret in one of the most widely accessible places on your phone. Here is how the leak happens and how to avoid it.

A screenshot is an ordinary image, and ordinary images go into the photo library along with holiday pictures and receipts. Nothing marks it as a secret, so it is treated like any other file. Anyone or anything that can see the library can see the key, the code or the recovery detail. The convenience of a two-second capture is exactly what makes it a weak place to keep something sensitive.
Apps and cloud backups can reach the photo library. That means the image may exist in more than one place: on the device and in any cloud account linked to it. The risk is therefore not limited to the phone in your hand.
One weak point is enough to expose every copy.
Yes, though the situation is easier. A custodial wallet spares you a seed phrase to store, which removes the most dangerous thing people tend to photograph. Login codes and recovery information, however, still deserve care, because they can open access to your account. Nexus Pay works this way: you open the wallet inside Telegram, so what needs protecting is your access, not a phrase written on a piece of paper. Treat those access details as secrets and keep them out of the gallery.
Start by finding any images of keys, codes or recovery details in your gallery and deleting them. Then check whether a linked cloud account may hold a copy, since a backup can keep an image that you removed from the phone. If a secret has been sitting in the library for a long time, it is reasonable to treat it as exposed and replace it where the service allows. This is general information about good habits, not a guarantee against every risk.
Blockchain transfers are irreversible: nobody can bring back a transfer sent to the wrong address. If someone gets hold of your access and moves funds out, there is no button to undo it. That is why prevention matters more than cleanup, and why removing an easy leak point such as the camera roll is worth a minute of effort. Small habits here protect you against a mistake that cannot be fixed afterwards.
Use the security options built into the app you rely on. In Nexus Pay, for example, you can turn on an optional four-digit access code and link a Google login as a second way in. The main share of crypto funds is kept in wallets without a permanent network connection. If you have a card and worry that something is wrong, you can freeze it in the app in one tap and unfreeze it later.
