Does the mobile phone have software to prevent others from peeking from the side?

Safer encrypted chat software includes Bat app, WhatsApp, Telegram, etc.

Reminder: Overseas software cannot be used directly in China.

All three softwares adopt end-to-end encryption technology, which can effectively protect users' privacy and security.

Bat app has preset functions such as secret message, two-way exit, secret chat mode, etc., which effectively prevents people around you from viewing chat content.

Secret chat mode: information coding of both parties, including avatar and name. Chat content cannot be forwarded, recorded, etc. You can't know who you are chatting with even if you take a candid photo.
