Razer PHONE 2 - People cannot hear me when I call; Poor network coverage affecting calls

While possibly irritating, a coil whine is harmless. However, you may opt to replace it if you are really
bothered by it.
To replace the Razer Phone charger, follow the steps below:
1. Ensure that the noise is really coming from the charger by plugging it into other power outlets.
If the noise does not occur when plugged into another power outlet, then it is the faulty
power outlet emitting the sound, have it repaired by an electrical professional.
2. Once confirmed that the noise is coming from the charger, contact Razer Support to process the
replacement.
