Yes, you can change the theme. But I hate Vodacom so much that I can't stand even having a wallpaper of theirs saved on my phone lol.Waiting for something on XDA Developers.
Since calls seem to record on VoLTE, seems I might not root over all.
Also, you can change the theme without rooting?
I am thankful though, that the startup and shut down screens are not that Vodacom rubbish that gets put on Samsung phones.
Only thing I'm missing is Odin right now. Other than that, I'm loving the P30 pro!
