Nearly three weeks after the release of an obscure KitKat firmware (B127SP02) for Ascend P7, an update to that firmware is being pushed out in a few European regions under build number B133SP01 (V100R001C00B133SP01). The Android version still sticks with v4.4.2 KitKat but it does offer some new features like Smart Cover mode, new Sound settings, bug-fixes for native apps, as well as other performance and feature enhancements to improve system stability.
