After using the app with no problem for over a year, it suddenly keeps asking me to verify, my number, then repeatedly asks me to enter a valid number. This is the same number I've used since installing the app. I can receive calls but can't initiate them. I tried uninstalling and reinstalling it, but have the same problem. I would have rated it a 4 or 5 before this happened, but it's worth zero stars to me now. Such a disappointment!

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.

There's a problem with memory control. Imagine a device with a 256 GB MicroSD inserted. With about 20GB free of main memory and plenty of free space on MicroSD. But IMO thinks there's no free space. Hint - "File Manager +" also thinks there's "-96" out of 64 GB of memory. Please, solve this issue. It makes one unable to use IMO on a functional device with plenty of free memory.
