Its call developer option, this option in settings+about phone+ software then clicking untiit turned you into a developer, based on cyber security test this option turned your device into untraceable.
Note: this option will have it own risk like, not being able to track the devices if stolen or lost but for someone that have privacy in mind dont you think having such option in your cryptocurrency devices at least not your main devices will increase your privacy?
Perhaps the developer options in the android devices that I have known for long has nothing to do with security towards your cryptocurrency protection, it only helps you customize your device to a level that you desire, especially device performance. We can as well say that it helps protect or debug usb related attacks. But however for android or iPhone devices it rarely have such attacks.
Hence one of the most common ways of protecting your hot wallets on any devices (devices that you use frequently for online activities) is manually checking for application updates and updating your devices to the latest version. It helps you fill up the gaps that hackers have discovered in the previous versions.
To further buttress, techniques to keep your devices safer is quite not really the same with bitcoin technical discussions but yet it’s valid, one of the crucial steps that can keep you ahead for theft in this part of the world is by using a hardware wallet and then have a safe box at home to store it, since here we have limited kind of thieves they rarely attack for cryptocurrencies so that can actually help.
