Hi all,
A few months ago I submitted a question for help to the community because I had strange white shadowing surrrounding text characters . This was only a problem in a certain subset of screens and apps. My phone is a Galaxy A13.
I found the cause of the problem today.
I had 'High Contrast fonts' switched on in the acessability mini menu.
What a pillock. (I would have said pilchard, but I love pilchards 😋 🐠🐟🦈).
