Users have reported that the Note 4 freezes and doesn't wake up after sleeping
Users have reported that the Samsung Galaxy Note 4 freezes and doesn't wake up after sleeping. This issue seems to be related to the "Marshmallow" update, as some users have experienced freezing issues after installing it. Several users have suggested trying the "wakelock" option, which doesn't use much power. This can be done by installing a "Wakelock Detector" app if your phone is rooted.
Additionally, some users have reported that the Facebook app on the Note 4 frequently freezes when trying to watch videos or access links. To address this, it is recommended to clear the cache and data for the Facebook app in the Application Manager settings. If the issue persists, a more comprehensive solution is to wipe the cache partition by booting the device into recovery mode and selecting the appropriate option.
If the freezing issue is not related to a specific app, it may be caused by corrupted firmware. In this case, a factory reset might not resolve the issue, as it could result in reinstalling the corrupted files. Instead, one user suggested reinstalling the firmware using Samsung Switch to ensure a clean installation.
It is worth noting that some users have also experienced random reboot issues with the Note 4, where the device restarts itself at random intervals without an obvious cause. This could be related to the same underlying issue causing the freezing problem.

One user suggested using the 'wakelock' option to prevent the phone from freezing
One user reported that their Note 4 device kept freezing after sleep mode following the Marshmallow update. They tried various solutions, including a cache reset, master reset, and removing the SD card, but to no avail. The user then suggested trying the "wakelock" option, which gives control over the phone's power management. The Wakelock Power Manager app, set to level 4 "PARTIAL_WAKE_LOCK", can prevent the phone from entering full power-saving mode and help it wake up from sleep mode.
Another user on the same thread also suggested the Wake Lock - Power Manager app, which they found effective in eliminating random freezing, lagging, and rebooting issues. However, they noted that their phone died after letting the battery reach 0%, and they experienced difficulties in rebooting it.
The Wakelock option is worth considering if your Note 4 device is facing similar issues of freezing after sleep mode. It appears to be a viable solution, as multiple users have reported success with this approach. However, it's important to keep in mind that power management apps may impact battery life, so your experience may vary.
