I am happy to write that the system is fast and responsive. Everything works properly so far, including the mobile version of Ecency. Based on my initial experience, the performance of the new version of the operating system, including its speed is better/faster than the previous version (Android 11). But the temperature of the smartphone is currently hot. Maybe because of the big (around 1.80 GB) download (and the install) of the update. I do not know. Either way, I am satisfied with the new version so far.
Have a nice day. All the best. Greetings and much love from Hungary.
