I have a Samsung Galaxy a3 2016. Recently the software on my phone was updated, which I am quite happy with, however, I hate the colour of the speech bubbles in my text messages.
Before my phone was updated, I was able to change the colours, but now there are no settings with this option. I can only change the background colour.
Am I stuck with these horrible grey & marshmallow colours, or is there a way to change this?
You could look to applying a theme @suzymcc which can change such things and or try another launcher such as Nova Prime as one of many available that allows further customisation.
