Rather rude tone to take for a reasonable question.
You do note in the article that you are locking at Android 16 - so the cost of following this guide is no security updates thereafter? That is a rather high cost (IMO immediate disqualifier), it is reasonable to discuss it and I don't see why you think it appropriate to rudely dismiss it.
Its great that you use the phone only for the camera. But you decided to post this as a guide and people who use their phones as a general-purpose device might be interested in discussing it too. The specificity of your particular use-case is nowhere visible in the article.
i didn't want to offend anybody.
Android come to the point where you choose so-calles "security" trading all your data (read privacy) to random guys in the cloud. Every person choose his own wisdom.
I mentioned my needs in the article and i use device as a phone also.
