I have been experiencing problems with my Samsung GS23 Ultra phone connecting with TMOBILE network ( erratic network connect disconnection) and updating security software on Samsung Galaxy Watch 4 Classic (unable to connect with servers) since latest One UI 7 Android 15 "update". Anyone else on the forum have same experience?
Have you had any luck since then? My connection has gotten progressively worse to the point where it's ultimately an expensive paperweight. I have no reception when I drive and only have access when I'm near wifi and use wifi-calling. I've gone to the t-mobile store where they removed my physical SIM and converted it to an eSIM. Unfortunately still encountering the same issue and was told it's a samsung device issue and not a tmobile service issue. I've only had this phone for two years, still looks brand new, and had to purchase a new phone just so I have one that works.
Unfortunately, my network connection with TMOBILE has NOT improved since the "update" to One UI 7 Android 15. Like you rightly observed, the connection is worse while driving. My calls drop randomly and frequently. I literally use wifi at home and work. There is something that TMobile, Samsung, and Google (Android) are keeping from customers. It is frustrating!! Before the "update," I had no issues with connectivity .
