First try to understand why you get conflicting signature error while installing Whats App+ on your Android phone or tablet.
Joy: My Brother Robert send me a link to install WhatsApp+ the pro & better version of Whats App to my mobile. The source link was APK file and I quickly downloaded it and while try to install the APK file I encountered this error – Application Not Installed with description as An existing package by the same name with a conflicting signature is already installed. I ensured “Install Apps from Unknown sources” is also ticked in Settings. I repeated the steps again and still my Karbonn A25+ throws up the same error. Robert can you help me resolve this error or explain us why this happens.
