The information was found in the application code from MIUI 12.5. Also, the development of tablets is hinted at by the control gesture interface in the Alpha version of MIUI Home 18.104.22.16889. According to the leak, the new items are codenamed Nabu, Enuma and Elish.
The Enuma tablet has the model number K81. It will support 4G LTE / 5G and will receive an LCD screen with a resolution of 2560 × 1600p, aspect ratio of 16:10 and a scanning frequency of up to 120 Hz.
