FunBike31The cogwheel option is what I meant when I had mentioned I had disabled the system update. I had already disabled the option to install updates automatically and through Wi-Fi and Cellular Data but ASUS is forcing the 18.0840.2103.26 update and ignoring those settings and keeps downloading the update every 30 minutes.
In addition to deactivating the automatic updates, you have to go to settings, update the system, click on the cogwheel at the top right and deactivate the download.
it is not a problem related to the firmware but a hardware problem, Asus absolutely does not want to communicate on this problem, everyone is reduced to hypotheses, to be likened also with the same problem on the Xaomi .
The most likely is a bad series of SOC 888s or a faulty manufacturing process.
