I lost the Voltage tab in System Tuner or 3C Toolbox!?
The voltage tab has not been removed and will never be.
This can be due to one of the following:
- The kernel was updated and it does not support voltage control
- The kernel was updated and System Tuner or 3C Toolbox do not support its voltage control interface
- The app lost root access during the update due to SuperSU requiring confirmation on app update (this can be disabled in SuperSU settings).
If unsure, please send a support request from the app settings with a note on the issue your experiencing. From the report I'll be able to figure out which one of the above is the issue.
