Enabling VoLTE on a Rooted Lenovo K5 Vibe Plus: A Comprehensive Guide
VoLTE (Voice over LTE) is a cutting-edge technology that enhances the voice quality on LTE networks. However, if you're using a rooted Lenovo K5 Vibe Plus running LineageOS 14.1, you might have faced issues in enabling VoLTE. This article will guide you through the process to ensure you can reap the benefits of clear and reliable voice calls.
Understanding the Issue
If you have to toggle on/off the enhanced 4G LTE mode every time when you turn on your mobile or activate/disable data, you're probably experiencing a workaround for enabling VoLTE. This workaround isn't ideal and could lead to confusion. During the discussion, it was suggested that since you have a custom ROM installed on your device, you should try re-flashing the phone and installing the appropriate ROM if the issue persists.
Why a Custom ROM Might Help
When you rooted your Lenovo K5 Vibe Plus, you installed a custom ROM based on stock Android 7.1.1. The issue you're facing might be related to the custom ROM you are using, as it may not have the necessary codes to enable VoLTE. This is a common issue with rooted devices, as not all custom ROMs include VoLTE feature due to limitations in the Android version or the specific hardware support.
Manually Enabling VoLTE
If your custom ROM does not support VoLTE out-of-the-box, you might need to manually enable it. Here's how:
Launch your default phone dialer app.
Input 4636 to access the network testing page.
Scroll down to find the option and select Turn on VoLTE provisioned flag.
Once you've enabled the VoLTE provisioned flag, VoLTE should be available for use.
Implementing this manual workaround should resolve the issue, allowing VoLTE to function as intended on your device.
Limitations and Alternatives
It's important to note that not all devices and custom ROMs support VoLTE. Since Lenovo K5 Vibe Plus is running Lollipop (Android 5.1.1), it may not have supported VoLTE as a default feature. However, newer custom ROMs such as those based on Marshmallow might offer VoLTE support. Installing a custom ROM that officially includes VoLTE would ensure a smoother user experience and eliminate the need for manual workarounds.
If your goal is to always have VoLTE enabled and you're open to installing a newer custom ROM, following the steps to re-flashing the device becomes more worthwhile. This process guarantees that all VoLTE-related features are correctly integrated, providing a seamless experience.
In conclusion, if you're using a rooted Lenovo K5 Vibe Plus, the first step is to ensure your custom ROM supports VoLTE. If it doesn't, manually enabling VoLTE through network testing settings is a feasible workaround. For the most reliable and hassle-free solution, re-flashing with a compatible custom ROM that supports VoLTE is recommended.
