From the day I buy samsung S23 Ultra phone facing network problem. When I switched the sim card to my other different brand phone working well, getting stable signal. Why in samsung, I didn't get that. I already give my phone to the service center. They say have problem with software so reinstall the software but the problem still persists. I think the problem is software from samsung itself. I hope samsung give updates to solve this issue. Sometimes very frustrating to deal with this network issue...
Fir older model.new software update just bring damage to the phone.mine got greenline for s22 plus and green screen on s22 ultra..my s23 ultra anz zflip 5 still ok with 6.1.1 software
