So I have an Android-Samsung Galaxy Quattro and in it I have an app of the name ''PhoneBattery'' and whenever I try to uninstall it, it doesn't get uninstalled. I tried uninstalling it from the menu>select app>uninstall but it doesn't get uninstalled. Then, I went to Settings>applications>PhoneBattery app but the 'uninstall' button is dull coloured(which means you can't click it) so I am having very problem with that app. Whenever I do any work on my mobile, the app opens itself between my work and due to this app my mobile has become very slow and also gets hanged. PS I have also tried to find the app in 'Files' folder but there also I am not able to find it. Please help! Thanks.
