Three Points Touch TP At The Same Time, And TP Fails And No Reaction Occurs
- May 01, 2019-
Reason analysis: TP IC itself algorithm problem.When set to a maximum allowable two fingers, no escalation occurs with a third finger.
Solution: some IC algorithms suppress the escalation of large escalation points. Current smart phones generally support more than two points. When more than two points are detected, only the first two points are reported: namely, two points of escalation ID=1 and ID=2.
