Ever since this controversy, I find myself checking what type of phone people are using. I find that more than half of Chareidim have smartphones.
You sound pretty judgemental there. “Checking what type of phones people are using” means nothing. You have no idea how many of them have filters! Filters which block out Shmutz; Filters which block out unnecessary sites suited for entertainment purposes, or even Filters which totally block Browsers and Apps. I know many people who have smartphones which are totally disabled; the sole purpose of the smartphone is for Whatsapp (which you discuss separately if you think it is a problem, but is definitely not anywhere near the ???? we associate with smartphones) and for the quality of the camera.
Please be ?? ??? ???? when possible.
