App works good for me ...Pixel 3a xl. Share function works good. Had for approx. 4-wks now. One problem is sometimes voice gets "hollow" sounding on my end. Called party also has noticed a few "sound" problems in same area. This happens 2-3 times during call, but not evderytime... but enough to be of concern for me.But I do like and suggest trying out. I do not use the paid version at this time.

Edit Dated April 17, 2023: I guess to continue using the service and have increased or same functionality, the developers require subscription? What exactly is the benefit to consumers?? -BES Best Caller ID and Spam Blocker so far. It also works well with my phone and mobile data provider, which is third party software operating on TMobile network. A little clunky when doing reverse number lookup, but overall I endorse this application. May I be a paid tester? Serious question 🤔 😀

5/28/21 When I first got the Cube CallerID app I loved it because like my embedded caller ID from my carrier it did outgoing caller ID. But just a few weeks later now it only does incoming caller ID and the outgoing was important to me and is dearly missed. Please program your caller ID app to do outgoing caller ID again and bring it back to your Cube CallerID app. I have the Premium Call Recorder and it works fine. 😥

Hello, thank you for your feedback. You can look for info about a particular caller directly from the app menu. Also, we specifically removed the popup during the outgoing call because we suppose that you know who you call, usually. But we would appreciate your explanation why you may need that. We will then consider adding it back. Thanks
