I've used exdialer for the past several years for free on an s2 and I now have an s5 and a couple s4s in the house. The app is still technically free but after the 14 day trial period it nags you...So, I'm trying to decide if I want to buy a license for all the devices or if there are some better options. Basically if I call or receive 5 calls from the same person, it shows as 5 vs. grouping them. This is beyond annoying. Any other dialers that are recommended? Thanks!
