Is it possible to determine the total number of hours the smartphone has been used?
Before the popularity of Android smartphones, people who used phones like Nokia used a special code (* # 92702689 #) to determine the total talk time.
That is, when buying a phone, a special code was dialed as a number to find out whether it was new or how many hours of talking, and the device provided information about itself.
The total talk time could not be reset to zero by resetting the phone to factory settings (sbros (https://t.me/gsmgurus_FAQ/915)) or by the “firmware” method.
Since in the past the phone was mainly used as a means of communication, the talk time was estimated as the total operating time of the phone.
Unfortunately, it is almost impossible to know the total running time of most Android smartphones or the time of first activation (activation). The statistics in various special codes and system settings are reset to zero after turning the smartphone off or resetting to factory settings.
On some smartphones, such as Samsung Galaxy devices released for the South Korean domestic market, the first call date is displayed in the system setting and cannot be reset to zero.
The logical method is that Apple devices have been used, for example, in iPhone smartphones. According to him, it is mandatory to take a new smartphone out of the box and connect to the Internet during the first activation process. A device connected to the Internet via a SIM card or Wi-Fi network sends information about activation to Apple's servers and is considered "used" from that point on.
Before buying an Apple device, you can check it on the official website via its serial number (written on the box): https://checkcoverage.apple.com/ru/ru/
Using the following site, Android devices can be identified only by the serial number of the date of manufacture: https://sndeep.info/ru
