Ever since the update, my text background is white and the bubbles are yellow and blue only. I have no settings area like before where I can adjust it. I can change the background but that's it. I can't adjust or change the bubble or its color? It's really hard on my eyes. Is there a way to chsnge them still or do I have to download a theme? Seems silly to chsnge the theme for a text bubble option!
I have an S5, S4, and Note 2, and I also got fed up with the Stock Messaging app.
I highly recommend using Textra SMS. It has about 250,000 good reviews, many of them from Samsung users.
It's not one of those apps that use data and give you a separate phone number, Textra is a replacement stock SMS app with major customization.
Here's a screenshot of the feature you seek:
I have mine set to AMOLED-friendly black since I use Samsung, and I also enjoy the "Send Delay" feature for all the times I need to fix typos after hitting send.
Hope this helps!
