What is the firmware version of Lenovo A798T? Can I install software for firmware 2 1?

Hello dear users:

We're sorry for the confusion. Lenovo A798T is equipped with Android system, please understand.

Third-party software usually requires adaptation to models above the Android system, if the mobile phone above the Android system can be adapted, so if the third-party software is installed with the applicable firmware above, then the A798T can be used.

However, Android software development is for all models, and there is no special compatibility test for all manufacturers' models, so the software version may have problems with system compatibility and performance requirements, and cannot guarantee that it can run normally on your model.
