The more I use my apps today after the update yesterday, the more I find most every WORKING function on Nougat they have destroyed with Oreo. Just discovered my editing capability is limited to a yellow highlighter or a purple??!!! pen on images. Then there's this useless battery fully charged icon that appears on the left side of the status bar...why??? We already had a battery fully charged indicator which now is redundant next to the clock. Add the loss of user interface customization in Settings to the list too. Everything that worked, Oreo has broken. I may drive to an Authorized Samsung repair facility and have them put Nougat back on if that's possible. I'm so beyond frustrated. Wonder if anybody who created this mess of an OS is listening?
