The Touchscreen Is Unresponsive
The phone does not respond to touches on the screen when the device is powered on
The Phone or an App Crashed

Dust or debris inside the speaker can make it sound robotic. The best way to clean it would be with a soft bristle toothbrush. Gently brush the speaker to remove any debris that has accumulated.

The Wireless Connection Is Weak
The phone has weak wireless connection.
Wireless Connections Have to Be Reactivated
The phone does not connect to the wifi, disconnects from the wifi, and has low-range of wifi. Access the available connections and let the device find and display all available connections.

The Wireless Connection Is Weakened by the Motherboard
The motherboard could impact the phone’s processing power. The device will experience weak connection if it is slow to respond to input effectively and render the webpages. To improve wireless connections replace the motherboard using the replacement guide.
The Charging is Slow
The phone charges at a significantly slower rate than it should
The Connection to the Phone Could Be Weakened by Lint, Dust, Corrosion, etc.
Use a flashlight to see inside of your phone’s charging port. If you see anything that could be interfering with the connection to the charging cable, use a toothpick to remove it.
“Tip:” When doing this, be very careful not to damage any components inside the charging port.
The Charger Is Weak
