If your device is overheating, remove any case, close unused apps, and avoid using the device while charging. If the problem persists, restart the device and ensure all software is updated.
To free up storage space, delete unused apps, clear cache data, and move media files to a cloud service or external storage. Additionally, you can use the Device Maintenance feature in Settings to clean up unnecessary files.
To set up a fingerprint lock, go to Settings > Lock screen and security > Fingerprints. Follow the on-screen instructions to register your fingerprint and set it as a screen lock method.
Use the Samsung Smart Switch app to transfer data from your old device to your Galaxy S7. The app supports data transfer via USB cable, Wi-Fi, or computer. Ensure both devices have the app installed and follow the on-screen prompts.
If the camera is blurry, clean the lens with a microfiber cloth. Ensure the camera app is updated and try resetting the camera settings. If issues persist, restart the device or clear the cache of the camera app in Application Manager.
