I would like to know: As host when my video is off while screen sharing can participants still see my screen or only when my video is ON? Also while screen sharing can participants see my chat discussions?

As many academic institutions are moving to online class,they need support from zoom.

I found on a site that Apk Zoom can break Smartphones and M-Banking? currently it is undeniable that it is in the public spotlight because of a number of reports regarding security issues on its platform. After the Zoombombing flare up, Indonesian netizens complained about the latest security issues that were suspected of being in Zoom. Based on the search, this complaint was filed by the Twitter account @akungangeninn. This account had time to upload another account's story claiming that his iPhone was accessed by another party after using Zoom. So, the account tells that after he used Zoom and opened Instagram, he suddenly lost control of his device. Initially, he felt it was natural because it was not uncommon for his iPhone to experience lag. But after that happened, suddenly his iPhone responded to the Instagram Stories that was being viewed by typing the words in the Reply column of the upload. The shocked account owner immediately closed the Instagram application, but another party who was said to be accessing his device immediately tried to open the m-banking application. He also admitted that he had difficulty turning off the device. Finally, the action he took to stop it was to remove the SIM card, so that the device's internet access was turned off. Because, he said, he also had difficulty turning off internet access on his iPhone.
