It’s a mistake few persons entirely new to cryptocurrencies make, the idea of going to get pen and paper or some diary to write it down in for first verification always seems tasking and so, they would want to screenshot. Some wallets wouldn’t even let you but, that’s rightly something you shouldn’t do as, you never can tell whom might get into your device someday, either authorized or not and can have access to that seed.
You are right bro. Many take screenshots without realising it initially, especially when everything seems new. But this small mistake can bring us great danger one day. For this, we have to be careful from the beginning. Taking screenshots means keeping a door open because if the door is open, any person can come in at any time, you don't understand. For this, I will say that although it is a little tricky to keep a handwritten note, I think it is a thousand times better in terms of security. In fact, even those we trust are not always aware. And it is normal not to be aware all the time. So I think it is wise to be extremely careful on your part.
