Network Related Issues
Some charging port assemblies also integrate antenna lines or routing. Replacing or damaging these components may lead to issues with cellular, Wi-Fi, or other network connectivity related problems.

Using non-genuine replacement parts can lead to various functional issues, depending on the quality of the specific part. This doesn't apply to all third-party replacement parts, but it largely depends on how well the part is manufactured.

Genuine (OEM) parts are built to strict standards using high-grade materials, while aftermarket parts may vary significantly in durability, fit, and performance.

Common issues - I replaced the part, my charging is slow or fast charging not working properly, My signals are dropping (connectivity related issues), phone is heating too fast, My LCD Display colour is different, My Speaker sounds are strange.

So it’s important to research the part before buying and always try to choose parts that come with a warranty. A good warranty (at least 3 to 6 months) is a sign of better build quality and more reliable performance.
