tibu app ,facebook scam

the app is on facebook and it called tibu . I installed it, after that it says me that you to have google video installed, so I have to installed google video also. after google video was installed, after some time watch movies, I closed my phone. And when I got my phone I tried to unlock it but it started lagging after multiple attempts I finally unlocked it and then I realized that something is not good 😐. I unstalled the tibu app but still it was not good so I searched my setting for google video and tried to unstall it but it kept on closing it self as it was very fast I could not unstall it , then I remembered that I have given it the permission. I tried to remove it but couldn’t, if you have a sumsung device you have noticed a small man beside your navigation buttons called accibilty you can click on it to turn off the permission for all the apps at once. after that only you can unstall it🫡.
