Currently i have a 14 pro max and s23 ultra. The 14 pro max is my daily device. I use the s23 ultra at work and photography. At work my iphone is practically a paperweight. My s23 ultra doesn't miss a beat. I can stream tv browse the web etc. My question is does the 15 series seem to have better antennas? I know the s23 has an upgraded 5g modem. Same as the 15 series. I would upgrade if i knew the signal strength is better on the 15 series. Fyi i use at&t for cell service. Thanks in advance
