My model number is i9802L. How can I take a screenshot?

According to your description, i9802L is not listed in China at present. The phone number or your model number is wrong. I suggest you check the model information in detail. You can remove the battery and check the model information on the white sticker. So that we can provide targeted information. At the same time, you can also visit Samsung official website for reference:

In the meantime, you can refer to,

Mobile phone screen capture refers to the function of capturing the current page of the mobile phone in full screen and saving it as a picture. The screenshot method is as follows:

Method 1: press and hold the Home button and the power button at the bottom of the screen for about 2~3 seconds. When you see the screen border flashing and letting go, the screenshot is successful.

Method 2: Standby-Application-Settings-Actions and Gestures-Palm Action-Palm Action Slider Open-Screen Capture Slider Open. (S5 mobile phone, this option is to slide the palm to capture-Open)-Just slide the side of the hand from right to left (from left to right) to take a screenshot. ?

Method 3: Standby-Application-Settings-Assistive Functions-(Agile and Interactive)-Helper Menu-Helper Menu Slider Open-Screenshot of White Box Selection. ?

If you use a Note series mobile phone, you can also take a screenshot with a stylus. Operation: Take out the stylus-hold down the key on the stylus and click the screenshot. After the screenshot, click the check mark in the upper right corner to save.

If the method is correct, you still can't take screenshots, and you can back up important data (contacts, photos, memos, etc. ) and try to restore the factory settings.
