i found this thread discussing about sleepy beauty
Ok this is what worked for me.
1- Turn off your note 5
2- Press the volume up button and home button together
3- while keeping it pressed Press the power button
4-It will open The system screen find cache and clear it- (DO NOT DO ANYTHING ELSE) once its done choose the restart option
5- I also got a 33 to 40 mb update yesterday. Do not update from the fone use smart switch to update it will download a 1.4gb file meaning it will reinstall the system.
My fone for 2 days now is not freezing. before the problem occurred at least 5 to 6 times a day.
Just in case make a backup although i didn't loose any
data .
Let me know if it works for any of you.
at step 4 only can see 'wipe cache parition' nia. lol
not sure where to see the clear cache option
