Hi Guys, iPhone has poor cell quality - Basically goes between 1-3 bars even saying “No Service” sometimes. Not an issue with the SIM because that works well in my other 5s. Curious where the antenna’s are on this and if it’s an easy repair. I know one antenna is connected to the charging dock. Where does the other connect on the board?

Yeah it can be done Here’s the parts iPhone 5s Lightning Connector and Headphone Jack Here’s a guide iPhone 5s Lightning Connector Replacement A little bit though, I’m wondering if that’s not your issue…
