I'm using Nokia Lumia 630 dual sim phone since 2013. A year back, I installed truecaller but after few months I uninstalled it and installed truedialler. But I didn't find truedialler worthy and thus, uninstalled it. After that till the date I'm trying to install truecaller app but, it's not getting installed! still as of now I'm trying to install truecaller but, after initialization, it fails to install. What should I do?
