Please read i button in app. There will be some errors/bugs as i can test things mostly on my own Volvo and or bench. So when you send that log to me via email via settings i look what i can do Will be updated based on feedback. Thanks for your support I hope this will be useful and i will make it even more useful by time I don t take any responsibility what this app can cause by using it or while using it. I don t warrant any things this app says. Many are just best guess by study and will be fixed as noted. App doesn t have any tracking of users location permission asked due because of bluetooth permissions only what Google Play Store does itself counting etc . To access the hardware identifiers of nearby external devices via Bluetooth scans, your app must now have the ACCESS FINE LOCATION or ACCESS COARSE LOCATION permissions To have Wifi support needed to have next permissions CHANGE WIFI STATE and android.permission.INTERNET.
