Betas 2 & 3 we're fine for me on my S23 Ultra but when 4 came along it was a nightmare. Phone got hot, kept restarting in safe mode and another screen of computer jargon I couldn't read. I reported everything and was so glad Beta 5 came along as it's so much better right now. I'd backed up everything but it's a nightmare having to restart again but thankfully it wasn't needed. Roll on the stable version soon. Anyone know the date?
