What's new in v1.3.8

Correction: an earlier version of these notes said 5G in Russia runs only in SA mode on band n79. That is wrong: the networks launched in September 2026 run as NSA on an LTE anchor. v1.3.9 fixes the diagnostics accordingly.

📶 5G diagnostics: find out why there is no 5G

New on every SIM screen: 5G diagnostics. It answers the question "I turned on 5G SA, so why am I still on LTE?"

The app checks, in order, everything that has to be right for 5G:

  1. The modem supports 5G.
  2. The carrier settings allow 5G SA.
  3. The SIM's preferred network type includes 5G.
  4. Neither the carrier nor battery saver has switched 5G off.
  5. This SIM is the one used for mobile data. On dual-SIM phones 5G is usually used only on the data SIM.
  6. What the phone is actually connected to right now: 5G SA, 5G NSA or LTE, with the band.
  7. Whether IMS (VoLTE / VoNR / Wi-Fi calling) is registered.

At the top you get a one-line verdict naming the check that blocks 5G. Where the app can fix it, there is a button right under the check: Enable 5G SA, Open network settings, Open SIM settings or Restart IMS registration.

If every check passes and you are still on LTE, the screen says so plainly: there is no 5G cell where you are, or the network does not let this SIM onto it. No setting on the phone can change that.

⚠️ Warning about other IMS apps

If you have other apps installed that change the same carrier settings (vvb2060 IMS, TensorIMS, Carrier IMS for Pixel, Pixel IMS 5G, PixelCarrierSettings and similar), the Home screen now lists them.

Android keeps only the value written last, so an app that re-applies its own settings every time Shizuku starts can quietly undo yours after a reboot. For each app the list says whether it does that on its own or only when you use it, and whether its settings are active on your SIM right now. Tap an entry to open its app info page, where you can uninstall it.

🛠 Fixes

  • Typing a User-Agent no longer writes it letter by letter. Before, every character you typed was applied to the carrier settings straight away, and Dismiss could not undo any of it. Now nothing changes until you tap Confirm.
  • Your saved settings can no longer be replaced by carrier defaults. Before, if you opened a SIM screen right after a reboot, before your settings had been restored, the app saved the carrier defaults it saw on screen as your settings. It now restores your settings first.
  • The Wi-Fi calling name picker no longer crashes if the carrier uses a format the app does not know.
  • Long switch labels no longer run into the switch. They wrap onto a second line, and you can tap anywhere on the row to toggle it, not just the switch itself.
  • Choice dialogs are easier to use. They show the setting's name as the title, options are spaced apart, and long lists scroll instead of pushing the buttons off the screen.
  • Boot Diagnostics is readable. The newest entries are at the top, and long lines wrap instead of scrolling sideways.

Requirements: Shizuku ≥ 13 with Wireless Debugging enabled. No root required. 5G diagnostics needs Android 12 or newer.
Signed with the same key as previous releases, so it installs as an update.
