I am waiting for the Android Oreo Update for my #Samsung Galaxy S7 Edge. I would install #LineageOS but I couldn't find out if the "Always On"-Display-Feature is supported by LineageOS. It is an important feature for me quickly watching the time while I am shortly awake at night or just wanting to know the time.
Just try it. Do a TWRP Backup before, try it and just in case I doesn't fit your needs revert back.
