This WhatsApp call trick could let someone see your photos even when your Android phone is locked
A newly reported problem in WhatsApp on Android may let someone who has your locked phone answer a WhatsApp video call and then access your photo library without unlocking the device. This means private pictures could be viewed even if you use a lock screen.
Who is at risk
Android users with WhatsApp installed are most at risk if another person can physically handle their phone, even briefly.
What to watch for
Watch for anyone asking to borrow your phone, unexpected WhatsApp video calls while your phone is locked, or signs that your photo gallery was opened without your permission.
What to do
Until a fix is available, do not let others handle your locked phone, avoid answering WhatsApp video calls from the lock screen, and update WhatsApp and your phone software as soon as updates are released.
