Solutions to Sony Xperia Z2 Poor Call Quality

1. Case and Protective Covers

Different cases and protective covers can decrease the call quality of the Xpeira Z2. If it is a hard or metallic case the signal will decrease because metal interferes with it. The Xperia Z2 has metallic bezels and adding a huge case is not a good idea.

You should buy a case that is thin yet protects the phone. A TPU case is a good idea for your Xperia Z2 to fix poor call quality.

2. Poor Signal from the carrier

Check if the poor signal is happening only to your Xperia Z2 or to other smartphones too. Remove the SIM card and insert it in another phone. If the signal is still low, this means that it is a problem with your phone carrier and you should contact it.
