Some apps were caught snooping by security researchers Talal Haj Bakry and Tommy Mysk.
TikTok was one of them but they've recently fixed it in their latest update.
However, the apps below (incomplete list) didn't fix it by JUNE 30, 2020:
• CNBC
• Fox News
• Reuters
• Russia Today
• Bejeweled
• Plants vs. Zombies
• Zoosk
• AliExpress Shopping App
• Bed Bath & Beyond
The more complete list is at Mysk link above.
Anyway please remember to always update your apps.
