v7.0.0

Cell-Lock rework

1. Cell-Lock lists the live serving and neighbour cells at the bottom of the page. Tap a cell to lock it.
2. In NSA the cell table splits into an NR card (SCG, NR neighbours) above an LTE card.
3. NR neighbour cells are listed once, with their strongest beam.
4. New 5G lock rows: NR-ARFCN + SCS for a frequency lock, PCI + Band for a full NR cell lock. Each row has its own check button.
5. New 4G lock row: EARFCN + PCI. One PCI locks the cell, several make a multi-cell lock.
6. Dropdowns list the last 10 channels and PCIs seen, with coloured bands. SCS and band fill in automatically when they can be worked out.
7. The active lock is shown beside 5G, 4G and PLMN lock ("NR-ARFCN locked", "Cell locked", "Multi-cell locked", ...), and the row holding it gets a button to clear it.
8. PLMN lock accepts "520 04", "520-04" or "52004".
9. Clear ALL empties the lock fields.

New uplink card (DIAG mode only)

1. Per carrier band, bandwidth, RBs, MCS, modulation, BLER, layers, PUSCH and PUCCH power and PHY UL, plus Rank and TX mode in SA.
2. "Hide uplink" menu option.

DIAG mode improvements

1. Supports the external X55 modem on Snapdragon 865 / 870.
2. NR neighbour cells with beams.
3. Antenna measurements for every LTE and NR carrier.

DIAG mode compatibility

1. X55, X60, X62, X65, X70, X72, and X75 modems are currently supported.
2. X80 and X85 modems are only supported without encryption.
3. Other modems may work but support has not been tested.

Bands page improvements

1. The floating button is a single check that applies the band locks. Reset moved to the menu.
2. "Combine NR" menu option: one NR band list on modems with separate SA and NSA masks. It starts from the SA mask and applies to both.

Network page improvements

1. The throughput chart scales automatically and ends at the newest sample.
2. Rank is shown as a whole number.
3. Neighbour cells list the band first, in colour.
4. Antenna card headers show band and PCI only.
5. Test script: 1 to 8 parallel streams. There are no built-in server URLs anymore, you enter your own.
6. The test status line shows only while a test runs or has stopped.

App improvements

1. Android 10 support.
2. "Network page at start" option on the Info page.

Bug fixes

1. Fixed the daemon failing to connect ("Permission denied") on rooted phones whose kernel can't switch SELinux to permissive.
2. Fixed the DIAG helper not connecting under Magisk on some phones.
3. Fixed a duplicated LTE SCell in the CA tables after a CA reconfiguration.
4. Fixed an LTE carrier being listed twice after a slot move.
5. Fixed the Network page jumping when the test status line opens.

Daemon 5.0.0 (unchanged)
DIAG helper 1.22.33 (new)

v6.0.0

DIAG mode (experimental)

1. Optional DIAG mode (Network page menu, "Enable DIAG") reads the modem's diagnostic logs through a small on-device helper, alongside other DIAG tools.
2. LTE CA table with band, bandwidth, EARFCN, PCI, RSRP / RSRQ / SINR, Tx/Rx, MIMO, RBs, MCS, modulation and PHY DL / UL.
3. NR table for NSA and SA with band, bandwidth, NR-ARFCN, PCI, SS-RSRP / SS-RSRQ / SS-SINR, CSI-SINR, CSI-RS ports, MIMO, RBs, MCS, modulation and PHY DL / UL
4. Timing Advance on the LTE and NR serving cards.
5. Dual SIM support, each SIM's DIAG data kept apart.
6. Optional combined ENDC table ("Combine ENDC") with LTE and NR carriers in one table.
7. Needs root (Magisk or KernelSU). Where SELinux blocks the helper's socket, one rule is added until the next reboot.

DIAG mode compatibility

1. X60, X62, X65, X70, X72, and X75 modems are currently supported.
2. X80 and X85 modems are only supported without encryption.
3. Other modems may work but support has not been tested.

New throughput graph

1. PHY DL and UL throughput over a 2 minute window (DIAG mode only).
2. The scale follows the traffic around the reading shown, without jumping on every peak.

Replay support

1. Records the Network page (menu, "Enable replay"), also in the background, for up to one hour.
2. Freeze the page (padlock or double tap) to scrub back through the recording, with play / pause and fine scrubbing.

Test script support

1. HTTP POST/GET traffic from the Network page, with its status in the top bar.

Network page improvements

1. Reworked serving cell cards with per-band colours, gNB / Cell for NR SA and TA.
2. CA tables with colour-coded signal bars, MCS and RB bars, and text that shrinks to fit many carriers.
3. NSA is shown only while the NR leg is measured.
4. The card in view stays in place when cards above it change (NSA / SA switches, the SCG coming and going).
5. Menu options show their state when on (Enable DIAG, Enable replay, Keep screen on, Hide serving cell, Hide throughput, Combine ENDC) and are remembered.
6. TX power moved to Antenna measurements. No throughput chart on WCDMA.
7. SIM 1 turned off or removed is detected, as SIM 2 already was.

App improvements

1. "Hide navigation bar" on the Info page. Pages still swipe, and the freed space goes to the pages.
2. Smoother page swipes, and a tap right after a swipe reaches the new page.
3. Loaded modem state and unapplied cell-lock input survive screen rotation and theme changes.
4. Cell lock accepts the full 32-bit gNB ID range.
5. Info page credits asn1c (BSD 2-Clause), used for the helper's RRC decoding.

Bug fixes

1. Fixed the Network page jumping to the top while scrubbing a replay.
2. Overlapping NR bands (n77 / n78, n38 / n41, ...) resolved from the network's configuration.
3. Fixed a black box after a fling to the bottom of the Network page.
4. Fixed a failed modem read showing "No service". The last reading is kept instead.
5. Fixed the replay recording being wiped when replay was enabled again.
6. Fixed stale NR values and out-of-range LTE cell IDs being shown.
7. Fixed released LTE SCells staying in the table after switching to NSA.

Daemon 5.0.0 (unchanged)
DIAG helper 1.22.19 (new)

v5.0.0

New! Network page

1. Added a Network page that shows live cell information read straight from the modem via QMI.
2. Serving cell card: mode (LTE / LTE NxCA / NR NSA / NR SA / WCDMA / GSM), RRC state, colour-coded signal bars (RSRP, RSRQ, SINR, TX power), then band, bandwidth, channel, operator, PLMN, roaming, and cell identity.
3. Carrier aggregation table for LTE (P, S1, S2...) with per-carrier band, EARFCN, PCI, bandwidth, and signal bars, plus an NR aggregation card for NR secondary carriers.
4. Per-antenna measurements (RX0, RX1...) and a neighbour cells table, both collapsible.
5. SIM 1 / SIM 2 swipe, freeze button and pull-to-refresh. Polling runs only while the page is open and the app is in the foreground.

Dual SIM detection via QMI

1. SIM tab names now come from the modem (QMI), not the Android telephony API.
2. A SIM 2 that is turned off or removed is detected and checked at startup, when returning to the app, and on pull-to-refresh. Swipes then go straight between pages on SIM 1.

App improvements

1. The whole band cell (circle and label) is now the tap target, with more space between rows.
2. Ticked bands are white with a black tick; a band group that isn't fully ticked gets a soft white tint.
3. New bottom bar icons: signal bars for Network, a wrench for Bands.
4. The app now stops you from applying a RAT lock with no bands selected for it.

Bug fixes

1. Fixed swiping between pages sometimes getting stuck halfway.
2. Fixed the bottom bar occasionally fighting the page swipe.

Daemon 5.0.0

1. New read-only commands for the Network page: (nas_read) and uim_card_status.
2. Monitoring uses its own per-SIM connections, so it never changes the SIM that band and cell lock commands target.

v4.7.0

App improvements

1. The “Filter active” indicator now sits in the top bar, to the left of the title.
2. You can now Show/Hide NR mode, Usage setting and Quick select with a toggle
3. The band filter now remembers your last selection after pressing “Clear filter”, so you can turn the same filter back on right away.

Performance optimizations and bug fixes

1. Faster startup by removing forced pkill + 500 ms sleep at launch. The app now only kills a stale daemon if one is actually running.
2. Startup now sends 2 daemon requests instead of 4
3. DaemonManager is now held in a ViewModel, so configuration changes (e.g. dark mode toggle, display or font scaling) keep the same daemon and connection instead of killing and relaunching it.
4. Daemon shutdown now runs exactly once, off the main thread. Closing and quickly reopening the app can no longer kill the new daemon or cause a freeze.
5. Fixed a rare case where a reconnect during Apply could send settings to the other SIM
6. Fixed startup failing with “Failed to select SIM 2” on dual-SIM phones with DSDS turned off. SIM 2 is now shown as unavailable and SIM 1 works normally.

v4.6.2

SIM operator names, modified-RAT highlighting, tappable RAT titles

The SIM 1 / SIM 2 tabs on the Bands and Cell pages now show the carrier name (e.g. "SIM 1 - vodafone.de"), using an optional phone-state permission with a graceful fallback. RAT band grids are tinted when some of that RAT's bands are unselected, so partially-configured RATs stand out, and tapping a RAT's title now toggles all of its bands at once. No daemon change (still daemon v4.6.1).

v4.6.1

Re-Attach to network + floating-window top-bar fix

Adds Detach / Attach / Re-Attach actions to the Bands, Cells and Info menus. Re-Attach drops and re-establishes PS registration in one action (with an automatic single attach retry if the modem is left detached), backed by the new daemon v4.6.1 QMI NAS_INITIATE_ATTACH command. Also fixes the SIM tab row being covered by the title bar when the app runs in a floating/freeform window, by matching the top bar's systemBars top inset.

v4.6.0

Security hardening: daemon token auth, idle timeout, SELinux fallback guards

The root daemon now requires a per-install token on every request (-tokenfile), exits after 15 minutes without a client, and the app only enters and always restores the SELinux permissive fallback (skipping it when an unauthenticated peer holds the socket). Also fixes a stack buffer overflow when a modem reports an oversized Manual-PLMN MNC.

v4.5.5

Usage setting (voice/data-centric) option on the Bands page

New two-tab control under the NR mode section lets each SIM select voice-centric or data-centric usage preference, staged with the rest of the band lock and applied together on Apply. The section stays greyed out when the modem does not report a usage preference. Updates the included daemon to v4.5.5.

v4.5.4

Cell-lock keyboard starts numeric but switches back

Cell-lock input fields no longer trap you in a digits-only keypad on Samsung/Xiaomi stock keyboards: the keyboard now opens on the numeric/dial-pad layout but offers the switch back to the full alphanumeric layout.

v4.5.3

Simple blur behind the top bars, adaptive pager height

• Simple blur behind the top bars on the Bands and Cell-Lock pages (replaces the plain dark scrim; falls back to scrim-only on Android 11)
• Bands pager now sizes to the visible page, removing leftover scrollable space when a filter hides entire RATs
• Band filter: unchecking all bands of a RAT hides it; filter sheet save tick greys out when a SIM has no bands selected
