Authentic article: July 24, 2020 at 1 PM ET: One of the crucial common drone apps on the Google Play Retailer contains some worrying backend options, in line with two unbiased reviews caught by Ars Technica. After reverse-engineering the DJI Go 4 app, safety corporations Synacktiv and Grimm discovered that the software program at greatest violates Google’s Play Retailer insurance policies, and at worst, may have been used to spy on the corporate’s customers.
