Hi all. I am facing the above mentioned issue with my Note 4 also shown in attached image. I had been using Note 4 since 3 years and there was no issue till date. But from some days it start behaving abruptly and hangs a lot. Finally today my screen reflected me the attached image.
Sorry..I did not get what you are asking. But now I have checked online and found that many Note 4 users having this issue. Also I have got a suggestion to install wake lock manager. I have used that suggestion till now phone is running smoothly and figures crossed for future viability.
We apologize for the inconvenience caused. We would suggest you to visit nearby Samsung Service Centre so service engineer will examine your device physically. Please find service centre details in the link provided http://www.samsung.com/in/support/servicelocation/
