Question about ASUS ROG Ally

I can't help you with the second-hand ROG Ally. Mine is new and works well. Only the many updates are tedious. In my opinion, the problem with the SIM has not been solved despite several updates. We'll have to wait for version 2, which will hopefully not have the card slot directly under the fan. My card got too hot a few weeks ago and can no longer be used in the device. It is still recognised on the PC but that doesn't help me much. The only remedy is to install a fixed SSD disc.
