Tap anywhere that you expect to do anything (like taking you to someone's profile) and it will start calling them. I still keep being called by people for split seconds. It just keeps asking to be allowed access to contacts, then if you allow it, it will keep asking to invite your friends. The app has superb call and video quality, if only they could get rid of their UI/UX personel and replace them with some random people from the street, the app would become great.

You may block unwanted contact by long hold on his avatar-profile-block.Invitation by SMS is optional and you may turn off the pop-up when open the app.Regarding the issue with random click causing accidential calls,could you provide screenshots in new Imo Feedback?

Quality of calls is reasonably good but I am devastated by how much annoying is this app. It overwrites Do Not Disturb mode and rings anyway. A full screen caller ID pops up whenever you get a call (even if you are in another app, let's say an online game) and you can only minimize it and it will block some of your screen unless you reject the call. You cannot get rid of vibration even if you minimize or hit volume down key. It keeps vibrating, again, unless you reject the call. At the end, when the caller gives up, you will be taken to the home screen of the app which prevents you from continuing your business and you have to close the app and go to your desired application. All in all, I am looking for an alternative app which would give me a reliable call quality to just uninstall this and be free of its annoying features.

Update: After Feb 1 update, it is still not working. The app is stuck at the phone verification screen. United States is not in the list, never received the OTP. I've been using IMO and IMO HD for free for a couple of years now. However, my IMO stopped working in the USA since Jan 13. My contacts from other continents don't show up in the app and all my past conversations are lost. Please suggest.
