4g Magisk Module -

This is the most popular all-in-one tweak. It includes IPv6 optimizations, DNS speedups, and 4G signal retention scripts. It works on Snapdragon and Exynos devices.

A minimalist module that adds a new quick settings tile to toggle between "LTE Only" and "Automatic" modes. Perfect for users who need peak speed in known good coverage areas.

The benefits of using a 4G Magisk module include the potential for improved network performance and additional customization options without the need for a full system modification. However, users should be cautious and consider a few things:

This is the core question. Here is an honest assessment:

| Claim | Reality | |-------|---------| | Increase signal bars | Misleading. Signal bars are a human-readable representation of RSRP. Changing build.prop might alter the mapping of dBm to bars, but not the actual dBm. | | Faster download speeds | Minimal, if any. Your carrier limits maximum speed based on plan, congestion, backhaul, and radio conditions. TCP buffer tweaks can help on high-latency or lossy connections, but difference is often under 5-10%. | | Reduce ping | Sometimes. Enabling VoLTE or forcing LTE-only mode can reduce latency by 10-30ms compared to falling back to 3G for voice. But core routing is carrier-controlled. | | Unlock extra bands | Almost never. LTE bands are hardware- and firmware-defined. A Magisk module cannot enable a band your modem doesn’t support. | | Carrier Aggregation | Rarely. In some phones (e.g., OnePlus, Xiaomi), modules can re-enable CA combos present in modem firmware but hidden in the OEM's carrier profile. Requires deep knowledge. | This is the most popular all-in-one tweak

Verdict: For 99% of users, a 4G Magisk module will not magically turn 20 Mbps into 100 Mbps. Actual speed gains, if any, are marginal and situational.

This module modifies your device’s build properties and radio settings to lock the preferred network type to LTE only. It prevents the phone from dropping to WCDMA (3G) or GSM (2G).

Compatibility: Android 8–14 (rooted with Magisk)
Risk Level: Medium – Incorrect settings may break cellular data. Always have a backup plan. Also verify in Settings → About phone →

Before focusing on 4G, a quick refresher: Magisk is a suite of tools that allows users to modify their Android devices without altering the actual system partition. Changes are applied "systemlessly" — meaning they can be toggled on/off and don't break SafetyNet or Google Play integrity checks.

A Magisk module is a flashable zip file that modifies specific system properties, adds scripts, replaces configuration files, or installs apps, all within Magisk’s isolated environment.
