I replaced the front screen and back glass on my LG Wing referencing this Hugh Jeffreys Guide, and my LTE speeds have been suffering pretty bad lately. I’m attributing this to something that may have occurred during my repair, but is hard to pinpoint when it started occurring as I’m on WiFi most of the time and WiFi speeds are normal. This was my first phone repair, so I’m unsure what to look for to identify the LTE antennae apart from the WiFi antennae. Then once I find the correct antennae, what kind of damage should I look for? I understand it’s also possible there is ESD damage which would be impossible to identify, but I’m hoping to rule out other possibilities first. This piece also fell out during teardown and I’m completely lost as to where it goes. Is this important or related to this issue at all?
edit: this appears to be where the white piece goes.
It could be the LTE antennae. If you could look up your model and find out which antennae is LTE and Wifi then try to replace the LTE antennae. I dont’t think that piece is related to the LTE and stuff but it could be.
