Build a Device Compatibility Profile

Collect the device facts that actually determine whether software can install and run well.

Core ideas

Use these points to build an accurate technical model before changing the device.

• Record Android/API level, CPU ABI, RAM, free storage and screen characteristics.
• Identify required hardware such as NFC, GPS, camera level, Bluetooth LE or sensors.
• Include manufacturer restrictions on background activity and battery optimization.

Decision rule

Compatibility is a matrix, not a single “Android version” field.

Apply it on your phone

Record the device facts, source and expected result. Make one reversible change, observe the outcome, and keep the evidence needed to undo it.
