I deleted the app since it was all the time asking me to watch ads in order to give the numbers!!! I downloaded the Numberbook again (might be a newer version) right after And it's not working at all it freezes then I turn it off then delete it then download it many times still not working. I was also asked to delete other apps to dowmload it.! While I have a huge memory card that's free. I downloaded it on Samsung Note 5, it worked !!! They must change their software engineer I guess😕

I have been getting calls and messages from unknown numbers since the past 2 years now. I have around 150 people in my block list. Upon talking to 2-3 people, I got to know that they got the number from your app. I never downloaded your app and never uploaded my number. Please take appropriate action against whoever did this.
