Phones and PCs include a Trusted Platform Module: a chip that controls the device's main processor can only run software signed by the device manufacturer. This chip allows applications to use a technique called hardware attestation to detect if the operating system has been tampered in any way and in such a case block functionality or refuse to work altogether. If done properly hardware attestation is impossible to spoof, even by the device's owner. | Phones and PCs include a Trusted Platform Module | ||

Since many businesses and governments require their customers to download their proprietary application to their phones in order to use their services, and many of those applications refuse to work on a modded device, people are unable to modify their phone as they wish, or else they wouldn't be able to interact with those businesses that require or heavily encourage their app. | Since many businesses and governments require their customers to download their proprietary application to their phones in order to use their services, and many of those applications refuse to work on a modded device, people are unable to modify their phone as they wish, or else they wouldn't be able to interact with those businesses that require or heavily encourage their app. | ||
