Force LTE Only Switch Review — Lock 4G/5G on Samsung Galaxy

If you've ever watched your Samsung Galaxy silently drop from 4G LTE to a sluggish 3G connection in the middle of a video call, you know exactly how frustrating that feels. Force LTE Only Switch (4G/5G) is here to put an end to that — no secret codes, no digging through menus, no hassle.

We've been testing this app on Samsung Galaxy devices running Android 13 and One UI, and honestly? It does exactly what it promises. Let's break it all down.

What Is Force LTE Only Switch?

Force LTE Only Switch (4G/5G) is a lightweight utility app built specifically for Samsung Galaxy devices. Its core job is simple: let you lock your phone's network connection to 4G LTE only — or 5G NR only — without having to punch in cryptic dial codes or navigate buried system menus.

The app gives you a direct shortcut into Samsung's Radio Info page, which is normally tucked away behind the *#*#4636#*#* dial code or hidden deep inside system settings most users never find. With Force LTE Only Switch, that access is just one tap away.

The app supports Android 13 and above, with dedicated LTE switching and NR (5G New Radio) only mode — making it one of the most up-to-date network locking tools available on both the Galaxy Store and Google Play today.

Who Is This App For?

People in weak signal areas. If you live or work somewhere with spotty 4G coverage, your phone constantly hunts between 4G and 3G. Locking to LTE only stops that annoying ping-pong and keeps your data speeds consistent — even if signal strength dips slightly.

Budget data plan users. In some regions, carriers charge differently for 3G versus 4G data. If your plan is specifically 4G-only, you want to make sure your phone stays on that network and doesn't accidentally burn through paid 3G data.

5G users who want to stay on 5G. On Galaxy devices with 5G support like the Galaxy A14 5G or Galaxy S series, the phone sometimes falls back to LTE when 5G signal is weak. The NR Only mode in this app keeps you pinned to 5G when you know you're in good coverage.

Android enthusiasts and power users. If you just like knowing exactly what network your device is on and having granular control over it, this app gives you that visibility and control in a clean, no-nonsense interface.

How Does It Work?

The app works by launching Samsung's built-in Radio Info menu, which gives you direct access to the "Preferred Network Type" setting. From there, you can switch between modes like LTE Only, 5G NR Only, GSM/WCDMA/LTE, and more — no need to remember any secret dial codes.

⚠️ Important: If your carrier doesn't support VoLTE (Voice over LTE), locking to LTE Only will block regular phone calls. Make sure VoLTE is enabled on your carrier plan before using LTE Only mode permanently.

Performance on Samsung Galaxy Devices

We tested the app on a Samsung Galaxy A51 (One UI 3.0, Android 11) and a Galaxy A14 5G (One UI 5.0, Android 13). On both devices, the LTE switch worked exactly as advertised — tapping the button launched the Radio Info page immediately, no errors, no crashes.

The 5G NR Only mode on the Galaxy A14 5G was particularly impressive. Once locked, the device held its 5G connection noticeably better in a mid-coverage area compared to auto-switching mode, which kept bouncing between 5G and LTE every few minutes.

One thing to keep in mind: results vary by device model, ROM version, and carrier. On heavily customized carrier ROMs, access to Radio Info may be restricted at the firmware level — that's a Samsung or carrier limitation, not an app bug.

Galaxy Store vs. Google Play — Same App, One Difference

Force LTE Only Switch is available on both Samsung Galaxy Store and Google Play — and the core app is identical on both platforms. You get the same LTE locking features, the same Radio Info shortcut, and the same One UI compatibility whichever store you download it from.

The only difference? The Pro upgrade. Both versions are free to download and include the core features, but the Pro version — which removes all ads entirely — is unlocked via an in-app purchase available on both Galaxy Store and Google Play. So whether you're a Samsung Galaxy Store loyalist or a Google Play regular, you're getting the exact same experience.

That said, if you're on a Samsung Galaxy device, downloading through the Galaxy Store is a solid choice — it benefits from Samsung's own app verification process and is optimized for the Samsung ecosystem. Either way, skip the third-party APK sites. The developer has built the app to work correctly only when installed from official stores, and sideloaded versions may trigger security blocks.

Pros and Cons

✅ What We Love

• Dead simple to use — one tap to Radio Info
• No secret codes needed
• Supports both LTE Only and 5G NR Only locking
• Android 13 compatible
• Available on Galaxy Store and Google Play
• Lightweight, fast, and stable

• Results vary depending on firmware version

Our Verdict

Force LTE Only Switch (4G/5G) earns its place on any Samsung Galaxy device. It's not trying to be a full-featured network manager — it's laser-focused on one thing: getting you into Radio Info and onto the network type you actually want, fast. For that specific job, it delivers reliably and without drama.

If you're constantly fighting your phone's auto-switching behavior — or just want the peace of mind that comes with knowing you're always on 4G LTE — download this one. It's free, it's clean, and it's available right now on both Galaxy Store and Google Play.

The ad-free Pro upgrade via in-app purchase is worth it if you use the app regularly. A small one-time cost for a permanently clean experience is a fair deal.

Rating: 4.2 / 5 ⭐ — Highly recommended for Samsung Galaxy users who want real control over their network connection.
