Lenovo — update ineffective in k8 note

The new update(NMB26.54-94) was supposed to clear the DND popping up while placing a call etc, but Even after the update the same problem persists.
The Lenovo firm is requested to kindly update the k8 note asap as it's the consumers right to enjoy a perfect product.
Waiting eagerly for an immediate response.
Thank you.
