android - Face detection on Samsung devices -


i use android face detection api camera.facedetectionlistener .

i have several tablets.

  • a galaxy tab gt-p5110 2 version 4.0.3 (kernel: 3.0.8-365113-user dpi dell155 @ # 1)
  • a galaxy tab gt-p5110 2 version 4.1.1 (kernel: 3.0.31-523998 se.infra @ sep-98 # 1)
  • a galaxy tab gt-p5210 3 version 4.2.2 (kernel: 3.4.34-1135839 se.infra @ s0210-10 # 1)

the detection works on first on second tab 2, turn on face detection, preview flick , detection slow.

on tab 3, listener never invoked if did not detect faces.

i tried sample : http://developer.samsung.com/android/samples/mad-hatter-face-recogition have same issues.

is there known bug on samsung devices ?

thanks

it known samsung's devices perform differently. have treat different samsung's device carefully. can use 2 steps investigate issue: 1. pass bitmap directly detection api check whether can work. 2. check preview fps. maybe have set different parameters improve camera performance.
