About this test
This assistant works as a decision tree: from the symptom you report, it filters the most likely causes and gives you a fix roadmap in the right order, always starting with the simplest, safest step.
Most phone problems are software-related and can be fixed by the user at no cost. The assistant prioritizes those fixes and tells you when it's time to visit a repair shop.
