Hi SC_22, welcome to the Community, and thank you for reaching out. I can certainly understand the frustration of your device constantly changing from dark to light mode, and your device running a little hot. First, we should see if a third-party application may be to blame for this behavior. Consult this guide for Safe Mode: https://www.samsung.com/us/support/answer/ANS00062983/
You can also try clearing your device's cache partition from the Recovery menu, using these steps: • Ensure the device is powered off. If the device is unresponsive/frozen, press and hold the Power button for approximately 10 seconds or until the device power cycles. • Press and hold the Volume Up button and the Home button. • While continuing to hold the Home and Volume Up buttons, press and hold the Power button until 'RECOVERY BOOTING' appears in the upper left then release all buttons. • Select wipe cache partition. Utilize the Volume Up/Down buttons to highlight and the Power button to select. • Select reboot system now. Option is highlighted, utilize the Power button to select.
If Safe Mode and clearing the device's cache partition do not help, it may be time to try a fresh start through a factory reset. Follow the guide carefully, and back up any data and/or files you do not wish to lose: https://www.samsung.com/us/support/answer/ANS00062029/
If the troubleshooting is not helpful, the phone will need to be evaluated by a certified technician. For service in the U.S., you can take the phone to a local U.S. walk-in service location https://www.ubreakifix.com/samsung or to ship the phone in for service, please reach out to us via one of the following options: 1.
