There will always be moments you would love to take screenshots on your Android phone to save or share with friends. It’s something I love doing and I capture screen shots on my Tecno M7 easily without any external app. Root is NOT required.
Whenever I want to capture any screen on my Tecno, I simply hold down the lower volume button and the lock screen (power) button simultaneously for some seconds till I hear a click sound.
The volume button is on the left side while the lock screen button is on the right hand side of the Tecno M7.
The screen shots save automatically in the screenshot folder of the Tecno’s Gallery app. Right in the folder, you can edit or crop the pictures and share anywhere.
Let me hear from you if this works on your Tecno Android phone.
