Here's how to take a long screenshot on any phone without any additional apps. For example, here I'll screenshot a WhatsApp conversation.
1. First, open the WhatsApp conversation you want to screenshot.
2. Press the Volume Down button and the Power button simultaneously.
3. Your screenshot will appear. Tap it.
4. Then press Scroll.
5. Your phone will automatically scroll down. Once done, click the Done button.
Thank you, I hope this is helpful.
