Somedays ago, I installed a custom firmware in my phone, Galaxy S7 edge, and the firmware was UK version, hence it did not support VOLTE services on Indian Carriers.
So I was forced to install this application on my phone and use it for calling. This application is very bad, and I would like to point out the negatives.
1) The UI Interface of this application is absolutely obsolete and very extremely ugly to look at. The general interface is a mixture of yellow and white, and the textures are so bad that it feels as if the company stopped in between while developing the software. While calling, everything is completely green and it just looks horrible.
2) Most of the time this application never recieves incoming texts and calls. It's okay while outgoing, but while incoming, it is very poorly integrated. I have almost never gotten a proper incoming call or text from this application. Everyone says that my number comes as not reachable.
3) If you need to be able to recieve incoming calls all the time, then you need to keep your data enabled at all times, and keep this application running in the background. This absolutely destroys battery life and drains the battery like anything. My phone's battery life became half of what it previously was.
4) This application is very slow to integrate and work. If I have my data off and I turn it on and then make a call, the first three of your attempts do not work.
5) However, my biggest complain with this application is that, it is very extremely laggy. An application should be smooth and seamless. However, this one is just very stuttering. Opening and closing, as well as browsing through the application, it just is a pain to do so.
- Thank You! We appreciate your effort.
