4G Only

Introduction to 4G Only

Modern Android devices offer multiple network modes, but accessing them is often buried behind engineering menus or restricted by OEM settings. 4G Only solves this problem by giving users a clean, quick, and reliable way to open the hidden Phone Information screen—where LTE-only and NR-only network selections can be applied. Instead of navigating complicated codes or hidden menus, 4G Only provides a simple shortcut with a smooth Material 3 interface.

The goal of 4G Only is not to modify radio settings directly. Instead, it acts as a secure, lightweight bridge between the user and Android’s internal RadioInfo activity. This design ensures safety, transparency, and compatibility across a wide range of devices. For users who want more stable internet, fewer network drops, or better battery usage by locking into LTE, 4G Only becomes an essential tool.

Whether you're troubleshooting weak signals, optimizing mobile data performance, or simply want uninterrupted LTE speed, 4G Only helps you get there with clarity and ease.

What Makes 4G Only an Essential Tool?

Telecom carriers often switch between 2G, 3G, 4G, and 5G automatically. While useful, this auto-switching can slow performance or cause unnecessary interruptions. 4G Only helps users maintain consistent LTE connectivity by opening the exact Android screen where these network preferences can be managed.

Why Users Love 4G Only

• It opens the hidden Phone Information page instantly.
• It simplifies access that normally requires codes or deep settings.
• It uses a minimalist, Material 3 interface.
• It works without modifying system files.
• It operates smoothly even on devices with restrictions.

Instead of confusing engineering codes like *#*#4636#*#, 4G Only offers one clean shortcut.

Lightweight, Fast, and Built for Simplicity

One of the biggest strengths of 4G Only is its lightweight design. The app opens quickly, uses minimal resources, and doesn’t clutter your device with unnecessary tools or ads.

A Clean Material 3 Experience

• Modern layout built with ConstraintLayout
• Clear navigation for About, Instructions, and Set 4G Only
• Fast and responsive interface
• No complicated menus

The minimalist design ensures that anyone—beginners or advanced users—can use 4G Only with confidence.

How 4G Only Works Under the Hood

Many users think apps like this modify radio hardware—but 4G Only doesn’t. Instead, it redirects you to the Android system’s built-in Phone Information screen.

How the Process Works

1. You tap Set 4G Only.
2. The app opens the internal RadioInfo activity.
3. The Phone Information page appears.
4. You manually choose your preferred network mode:
   • LTE only (4G only)
   • NR only (5G only)
   • LTE/NR auto
   • WCDMA only, and more (depending on OEM)

Because 4G Only does not alter system components, its behavior is safe and relies solely on Android’s native settings.

Availability Depends on OEM and Android Version

Not all devices expose the Phone Information screen. Some manufacturers, especially certain global variants, block RadioInfo for security or carrier policy reasons.

Possible Scenarios

• Fully accessible: Most stock Android and custom ROM devices
• Partially accessible: Some brands allow view only
• Blocked: OEMs hide the RadioInfo activity entirely
• Replaced: Carriers may override settings

In all cases, 4G Only handles missing pages gracefully, informing the user instead of crashing.

This makes the app reliable even across different brands, including Samsung, Xiaomi, Motorola, Oppo, Vivo, Nokia, and devices running custom ROMs.

Why Locking to 4G Only Is Useful

Users often prefer locking into LTE-only mode for stability and speed. Even in areas with 5G coverage, 4G is often more consistent.

Benefits of Using 4G Only Mode

• Fewer connection drops
• Better internet stability
• More consistent upload and download speeds
• Reduced ping for gaming
• Prevents fallback to 3G/2G in weak areas
• Helps conserve battery compared to unstable 5G

For gamers, streamers, remote workers, and everyday users, 4G Only becomes a must-have tool.

NR-Only Mode for 5G Users

While many users want to force LTE, others want pure 5G. 4G Only gives access to NR-only options if your device supports them.

NR-Only Advantages

• Maximum 5G speed
• Better low-latency connections
• Superior bandwidth for video calls
• Ideal for high-demand applications

As long as your carrier supports NR-only configurations, 4G Only provides a convenient path to switch modes.

A Perfect Tool for Troubleshooting Connectivity

Sometimes network troubleshooting requires access to RadioInfo features. 4G Only simplifies these tasks.

Useful for Technical Tasks

• Checking signal strength (RSRP, RSRQ, RSSI, SINR)
• Viewing current network type
• Monitoring data usage switching
• Testing SIM or carrier behavior
• Diagnosing connectivity issues after updates

Professionals and technical users will appreciate this level of easy access.

Fast Access Without Complex Codes

Before tools like 4G Only, users relied on manually typing engineering codes into the dialer—codes that often don't work on all carriers or phones.

Common Problems the App Solves

• Dialer blocks secret codes
• Device suppresses RadioInfo
• Carrier disables engineering mode
• Users forget the codes
• Codes vary by Android version

By removing these barriers, 4G Only ensures consistent and hassle-free access.

An App Built for All Types of Users

Whether you're a beginner or an advanced Android user, 4G Only makes network mode selection easier.

Ideal For:

• Mobile gamers
• Travelers
• Users in weak signal regions
• People with unstable 4G/5G coverage
• Users who want better battery life
• Network testers and technicians
• Custom ROM users

Because the app is tiny, fast, and clean, it fits perfectly on any device.

Privacy-Friendly and Secure

Unlike heavy system apps, 4G Only respects user privacy.

Security Advantages

• No data collection
• No internet required
• No modifying system files
• Does not interfere with SIM or radio firmware

Your device stays safe while you access the settings you already own.
