My phone this morning would not allow me to screenshot something from FB, something I do every day. Infact I had a bunch from the day before. I thought it was FB, but when I tried to screenshot from my messages, it told me "this app doesnt allow screenshots." Every single thing I try to snap, no matter what app I am on, it tells me the samething. I have googled it, checked every permission and setting, the device help section, and powder down my phone. I don't know what to do!?@?
@BrieBee I would first try wiping the FB app's cache.
If that doesn't solve it, I would wipe the device cache partition. It wipes out incompatible or outdated cache information. It does not erase any user data nor applications.
To wipe the device cache partition:
1. Power off your device. 2. Power up while holding down the Volume up key and the Side key until the Samsung logo appears. 3. An Android recovery menu will appear. 4. Use the Volume down key to scroll down to Wipe cache partition. 5. Click the side key to select it. 6. Use the Volume down key to scroll down to Yes. 7. Click the side key to select it. The Cache will be wiped almost instantaneously. 8. Click the side key to select "Reboot system now"
I sometimes get this on Instagram, and I have found either restarting my phone, clearing the cache partition, and force stopping and clearing Instagram cache then it works, maybe it could work for you to but for facebook
