i replaced the battery and charging port as wellas the back glass. Now i have no service and says sim card missing. took back apart and checked connections all good tried reseating sim card several times no luck
I’ve seen this before. When you ordered the replacement port did you order one that corresponded with your model? Samsung has been known to use a few variants of charge ports and camera assemblies depending on model. If you didn’t use the correct port, it will give you the “no sim” message despite there being a sim card installed.
