Force 4G LTE: 5G Only Mode QJI

Force 4G LTE in two taps and stop your phone from dropping to slow 3G and 2G. This app opens the hidden Android network menu on your phone, shows exactly which option to pick and lets you lock 5G only or LTE only mode, then measure if the connection really got better. Is your mobile internet jumping between 5G, 4G and 3G all day? Android keeps the preferred network type in a secret "Phone info" menu (the *#*#4636#*#* code). No app is allowed to change it for you, so we do the next best thing: we find the way into that menu on your phone, try every known route automatically and show a picture of what to tap. Choose LTE only to force 4G LTE, or NR only to stay on 5G only. To undo, one button brings you back to automatic mode. What you get • 4G LTE only and 5G only in two taps — the app opens the Phone info menu and marks the right option (LTE only, NR only or back to auto). • Works with dual SIM: pick SIM 1 or SIM 2 with "Select phone index", step by step. • Automatic fallback: if your phone maker hides the menu, the app tries the Testing menu and mobile network settings, and tells you honestly what is possible on your model. • Live signal meter for both SIMs: dBm, ASU, RSRP, RSRQ and SINR, quality in plain words and a 60-second chart. • Find a better spot: walk around the room and the best signal stays on screen — handy for a 4G only mode or a weak 5G area. • Internet speed test: ping, jitter, download and upload over Measurement Lab servers, with history and sharing. • SIM and network info: operator, technology (5G NSA, 5G SA, LTE-A, LTE, 3G), country, MCC-MNC, roaming and which SIM carries data. How it works 1. Tap "4G LTE only" or "5G only". A short note reminds you about calls and VoLTE. 2. The app opens the Phone info screen and shows a picture of the list with the right line marked. 3. Choose LTE only mode for a steady 4G connection, or NR only as a 5G switch on a 5G phone with 5G coverage. 4. Press Back. The status bar shows the new network in a few seconds, and the Signal tab shows the difference. Who it is for Anyone whose phone keeps switching to 3G in a good 4G area, people on a 5G plan who want to stay on 5G, gamers and streamers who need a stable connection, and anyone curious about which tower and band their phone uses. Good to know In LTE only mode calls work only when your phone and operator support VoLTE. If calls stop, tap "Back to auto". On most phones the mode resets after a restart — just set it again. Some brands (many Samsung models) lock the hidden menu; the app shows the alternative path for your phone. The app changes nothing by itself: no root, nothing installed in the system, your warranty is safe. No ads, ever Locking the network, the signal meter and the speed test are free with no ads and no account. An optional one-time Pro unlock adds the cell towers around you with band, PCI and channel, a Quick Settings tile that opens the network menu in one tap, the full speed test history and a 10-minute signal chart. Pay once — no subscription. Ready for a stable connection? Install and force 4G LTE now.
