This app just might be my saving grace 🙏 I have factory reset twice and even started fresh but some how someone has still managed to remotely access, change everything I do and export apk files after accessing my camera and microphone. I shut off bluetooth, and location and they managed to turn it back on and make it unchangeable. As well as remove google maps all together. The amount of control is insane and if this doesn't work I'm burning every device in my front yard. (Not kidding)

Thank you for using our apps. Our apps may help reduce some attacks on your device. For best security, it is good to keep most things locked when possible, esp. the Internet Lock, as it blocks remote access. The System Lock can automatically turn off Bluetooth and Wifi. For more tips, see "Best Security Practices" in Help. Thanks.

Love(d) the app. Worked like it should without a hitch every time.... Then phone suffered a catastrophic event. Factory reset and BOOM.... found out that the only way to restore ANY of the previously purchased functionality was to restore from a backup. That nugget of info was literally buried in the help section and quite useless post reset. I might have considered repurchasing the lost functionality if the buried and effectively hidden gotcha clause didn't come across so shiesty. SAD.

Amazing app. Like a dream comes true, after more than a year searching and trying many apps, finally found one that actually proved to block my android microphone, without affecting the internal microphone usage on other apps. Big thanks for this app's developer. You are the best!
