#161 open camera slow performance for me

[Anonymous]

Hello, i like open camera very much and would like to use it instead of the android cam on my samsung J5 (rooted) and donate it.

There is only one thing that makes it impossible to do like described: With the android camera i can take photos quickly with a pause of about 1 second, in open camera there is a timelag between photos with more than 4 seconds. I tried a lot (facerecognition, focus, stabilization and so on) but the performance doesn't get better.
Do you have a hint?

Thank you and best regards
