Question Can't install Facebook, Facebook lite and messenger

[Mouser]

All apps on my phone flashed out by itself, including Facebook system app that came with the phone.
I have tried to download Facebook, Facebook lite and messenger back but it keeps saying"can't install app" I have over 4g memory space, I have cleared my play store,forced stop it but still the same thing.
Other app installed including Instagram.

Take it as a sign from above and don't install them. Use a browser.
