Android Authority's 5 best dialer apps and contacts apps for Android
Dialer apps and contacts apps are a bit of a niche market. In most cases, the stock dialer and contacts app is more than good enough most of the time. However, there are some cases where it may be necessary. The Note 8 occasionally freezing while using the contacts app is a good example. In any case, there are a bunch of decent options, but only a few really good ones. Also, we considered doing separate lists for contacts apps and dialer apps. However, generally speaking, if you get one, you get the other too. Both lists would pretty much have the same apps.
