S95B firmware 1420 issue about cleaning and performance

[Reve3]

hello everyone,
after upgrading to this 1420 firmware, i notice that every day i get the panel optimization popup, even if i click ok to run it, the popup comes back the next day... also i notice a lot of image freezes and audio problems. is it possible to go back to 1306 firmware?
is samsung working on fixing this problem?

Is there a way within the settings to define when it runs.
As at the moment it's every 24 hours.

I had a similar issue, someone suggested holding the power button down on the remote for a few seconds. When the tv restarts it loads up the with word OLED or something similar on the screen. Think it does a soft reset of the TV. You may get the pop up again which you can dismiss. After I did  that it solved the issue for a while anyway. The firmware is quite unstable, it hangs and crashes every now and then and when it does the issue starts again and constantly checks for updates and wants to do the screen refresh. Hopefully Samsung will have some respect for their paying customers and sort these issues out after taking our money for a product they have made worse with various updates.
