Broken or Defective Earpiece Speaker
No sound coming from the earpiece speaker during calls
Make sure the volume is turned up during a call (see volume instructions in the device manual). Use the volume controls on the side of the phone.

If the phone is turned up to maximum volume and there is still no sound coming from the earpiece speaker, then the earpiece speaker may be disconnected from the motherboard, check to see that the contact is connected properly.

Weak or no cell signal
When trying to make calls or send texts, there is no cell signal
Low Signal area
If you are experiencing weak or no signal it could just be a problem of your location. If you move from that location and your signal is better, than it is just an issue of weak cell service distributed by your service provider.
Faulty Sim Card or Driver
If you continuously have a problem of no signal, remove your sim card and re-insert it into the device. If that does not fix the problem then the sim card or the driver may be faulty and will need to be replaced.

When listening to music the audio is unclear
Knowing that the problem is with the headphone jack/driver, first check for any debris in the headphone port that may be block the jack from being fully inserted into the device. If the port is clear of debris and the jack can be fully inserted, then you will need to replace the headphone driver.
If the headphone audio is distorted first rule out if the headphones are broken. Check for frays in the chord and test headphones with another device. If the headphones work well with another device then you can ensure that the headphones are in working order.
