physical dipswitches or jumpers to control unwanted devices such as cameras,microphones, accelerometers, etc. basically a physical denial of anything unrelated to voice or message functions.

batteries removable by hand no tools or solvents required.

no battery power on plug operation.

modular construction, hardware components that are never going to be used for the benefit of the user, removable with no friction.

already planning on the battery section, cameras and other sensors (including wifi and bluetooth) would always be upgradeable unlike current phones without tools by using fix and switch method all except front camera (included privacy shield) and speakers
