Since installation of P3D 8.2.1 the issue is back, even when restoring CD2.5 which was running a few days before without this issue. SuperWipe or FullWipe and manual cleanup of SDCard didn't help too.
So where is this setting stored ??? Maybe activated by a Sense 3.5 ROM in Radio module ? Where else may this setting remain when clean system, data, cache and sdcard ?
It seems the European based rom have this feature in the power settings. I've been running insertcoin and RCMega Mix and am able to turn it off.
I think the setting got enabled by flashing other roms, and just stuck no matter if I went back to stock or at TMOBUS rom.
Seems to be correct, AFAIK CoreDroid 2.5 and P3D 8.2.1 are on European base and shows this issue.
Energy Sense 3.0 based on TMOUS (pls correct me if I'm wrong) seems not to be affected by this works fine in my case.
Update: Bulletproof 1.4 doesn't have this issue too (TMOUS based too ?).
I just started experiencing this issue yesterday. I flashed a bunch of roms then came back to ARHD 3.6.2. No matter what rom or kernel i try now I still get the same message. I make sure to flash super wipe every time so I don't know why I'm still getting this message. Any one know if it actually does put the phone in sleep mode the when screen is off or is it just an error message?
Glad to see I'm not the only one experiencing this issue.
Even when You install a Sense 3.5 ROM ? Energy Sense 3.5 (my favorite) has an option for configuring exact this parameters in power menu, I think other Sense 3.5 based roms too.
