There is a new bug though. If you have wi-fi turned off and the screen off, the screen will turn on and turn off every 20-30 seconds or so.
Solution is to leave wi-fi on but so much for saving battery life.
Anyone else have this error?
Another irritation is that when you take the s-pen out of the dock a note saying it has been removed stays in the bottom notification area and stays there preventing the use of the the pop-up until the note disappears which takes about 5 seconds. Too slow!
For s-pen detection go into settings > s-pen > select to turn off s-pen detection.
For the screen flicker do this,
Restore the device via Odin. Heres the link Download Odin 3.07
Also download the stock Jelly Bean FW from Sammobile.com. Heres the link
SamMobile Firmware Page
Select your device type, Os, version of device (gt-n8013, gt-n8000 etc.), and your country.
***YOU NEED TO MAKE A SAMMOBILE ACCOUNT, TAKES 5MIN***
Download proper Firmware for your device/variant.
Turn off device.
Reboot into download mode by holding power and volume down, wait until the note 10.1 boots into download mode. (It says odin mode at the top left and there will be an android in the middle of the screen)
Once in download turn on odin on your computer (after you install it of course), and plug in your device.
Odin will display COM: "3" or "12" or some number when connected.
Now click the PDA button and select the original samsung firmware you downloaded from sammobile.com. (after you've extracted it to your desktop or wherever)
Hit start when it loads, sit back relax, and grab something to drink/eat wait until the device reboots.
If that doesn't fix the screen flicker is bad hardware send it back to Samsung.
