Android versions also collect a lot of particularly sensitive data: they almost instantly assign the new identifier to previously collected data based on the SIM card, IMEI number, location data, IP address or SSID, for example. This also makes his anonymity somewhat questionable. In addition, the collection of this data cannot be stopped, and deleting advertising identifiers is not a solution. If all this is not enough, many applications ( – Xiaomi, Heytap – Realme, Hicloud – Huawei) have been discovered where data encryption is weak and decipherable and can be exploited in hack attacks.
