Today I tested the time laps upgrade for the second time and it made a huge difference comparing to the last one. here's the link to the video:
Must of the previous problems are solved, there is a bit of vibration which is caused by a miscalculation from me, I positioned the phone angle a bit low and at the end, the top part of the print would be out of the frame, so I tried to fix that mid-print, which worked but made that shake.
Also, I downloaded an app called Open Camera from google play, which has an option to lock the focus and exposure of the camera and also prevents the camera from closing itself.
All and all, I'm happy with the results, but I believe the third test that I did tonight will be even better. I'll share a log as soon as I edited the video.
