To ensure product quality, a wide range of tests are necessary. There are over 4000 software tests, more than 50 hardware function and performance evaluations, and 40 reliability assessments. The reliability assessments include (but are not limited to) high and low temperature tests, temperature cycle tests, abrasion tests, touch - screen crossed tests, small ball tests, roller tests, distortion tests, drop and micro - drop tests, and Mean Time Between Failures (MTBF) evaluations. These comprehensive testing procedures are crucial for maintaining the integrity and reliability of our products throughout their lifecycle.
