WhatsApp to Block Logins on Phones With Outdated Systems
WhatsApp is reportedly adding a rule for phones with old software.
Some Android phones and iPhones may be affected.
The rule is being applied through WhatsApp’s servers, so a regular app update may not be needed for the block to appear.
Affected users may see a screen instead of their chats.
That screen will tell them to update their phone’s operating system.
It will also explain how to check which version the phone uses.
WhatsApp has not said exactly which versions are too old.
The security measure is intended to reduce risks from weaknesses in outdated software.
WhatsApp is reportedly introducing a server-side restriction that blocks access on devices running outdated iOS or Android versions.
