- Phones that are unstable because they have broken audio implementations:
Alcatel one touch series (poor audio drivers cause system freezes and crashes)
HTC one m8 (causes freezes.)

WARNING: using Zoiper as a default dialer may interfere with dialing 911 emergency services.

WARNING: Please use only versions from the appstore, we have reasons to believe some of the (russian) .apk files floating on the web contain a trojan that might steal username and password and make fraudulent calls. The official zoiper from google play is safe to use.
