iPhone photos can look bad on Samsung devices due to differences in the technology and software used by each brand. To ensure that your photos look their best when transferring them from an iPhone to a Samsung device, there are a few steps you can take:
1. Make sure that both devices have up-to-date software installed.
2. Ensure the file format of the photo is compatible with the receiving device (for example, an iPhone photo may need to be converted from HEIC to JPEG).
3. If you're emailing or texting photos between devices, try sending them as attachments instead of embedded images for better quality.
4. Use a third-party app such as Google Photos or AirDrop for transferring photos between Apple and Android devices, as this will help maintain image quality on both ends.
