Hello blessie146! Thank you for participating in the Apple Support Communities.
We understand that your iPhone display has a violet tint to it when you view it from an angle. We'd like to look into this with you to see how we can help.
Do you have a screen protector applied to your display? If so, does this issue persist if that screen protector is removed?
Do you notice your iPhone display becoming unresponsive at all, or exhibiting unexpected behavior? If so, the following resource may help: If the screen isn’t working on your iPhone or iPad
You may also consider reaching out to Apple to look into this further. If available, you may be able to set up an appointment to have your iPhone inspected by a local Apple Authorized Service Provider: Get Support
Make it a great day!
