I have a Samsung A13-5G phone. I stupidly installed a weather app and it TOTALLY screwed up everything on the screens (made icons smaller etc.) I tried to go to the installed app(s) to uninstall them but the "uninstall" button for each app is grayed out and I can't go that route. Question is there a way to do a factory reset without losing my contacts. Is there a way to download or email my contacts before doing the reset? Why would the "uninstall" buttons be grayed out? Thanks for the help as always friends!
