Samsung Galaxy Note 20 Ultra Central Antenna (Service Pack)
Central antenna for Samsung Galaxy Note 20 Ultra (N985F), the part that ensures the device's network reception and 5G signal. It is a genuine manufacturer part, supplied as a Service Pack: the box carries Samsung repair packaging, with no refurbished or repaired part.

It is covered by a 2-year warranty.
Samsung Galaxy Note 20 Ultra central antenna: its role
The central antenna of the Samsung Galaxy Note 20 Ultra concentrates the device's wireless connections: mobile network, WiFi, Bluetooth and GPS all pass through it. It's a discreet part, but its condition directly determines the quality of daily connectivity.
A worn antenna or one damaged by a fall doesn't always cut the signal cleanly: it makes it unstable, with intermittent losses that are harder to diagnose than a clear-cut failure.
How to know if it's at fault?
Network dropping intermittently, calls cutting out for no apparent reason, WiFi disconnecting while the router works normally for other devices, or loss of GPS accuracy: these are the typical symptoms of a faulty central antenna on this model.
Before ordering, it's still worth ruling out a software cause (restart, update): if the problem persists after these checks, the part is the most likely cause.
What "Service Pack" means
This antenna is an original manufacturer part, supplied as Service Pack: it comes off the same production lines as those fitted at the factory on the Galaxy Note 20 Ultra, but in Samsung's repair packaging rather than the packaging of a new device. Nothing on it has been repaired or reglued: it's the packaging that sets it apart, not any treatment undergone by the part.
It carries the manufacturer reference GH97-25213A, to be checked before ordering to make sure it matches the part to be replaced.
Compatible with which Galaxy Note 20 Ultra?
This central antenna is made for the Samsung Galaxy Note 20 Ultra (N985F). Incorrect model identification for this type of component leads to a part that doesn't connect properly to the device's internal flex cables: checking the phone's exact reference before ordering avoids back-and-forth returns.
Precautions during installation
The central antenna connects via flex cables and fine connectors, located near the motherboard. Installation requires working with the power off, at an antistatic workstation, and avoiding any direct pulling on the connectors to prevent them from cracking.
Careful reassembly of the original screws and clips determines how well the signal holds up over time: a poorly seated antenna reproduces the symptoms it was supposed to fix.
Warranty
This part is covered by a 2-year warranty, applicable in case of a defect in the part itself.
