MG4Control Advanced settings for the MG4 Electric

The active mode lights up green for ECO, amber for SPORT and blue for the others. The state is re-read from the vehicle each time the screen shows. If the vehicle is not ready yet, the app retries every 3 s.

A rail tab whose page has no content on your firmware is simply hidden. Pick UNKNOWN above the mockup to watch it disappear.

Off, Low, Medium, High, Adaptive and One Pedal. In SNOW, no level can be changed (not even One Pedal) and the Energy saving button is greyed out: both modes are mutually exclusive. The UI reflects these rules instead of letting you send a command the car would reject.

Toggle button under CUSTOM. Try it in the mockup: turn it on, then try changing the regeneration.

ICA on SWI133 and SWI132, TJA on SWI68, 69, 131 and 165. On “VSM” firmwares the limiter and ACC/TJA are two independent systems: the single selector enforces exclusivity, picking one turns the other off.

On SWI133/SWI132: overspeed alert and speed-limit change alert, greyed out and forced OFF when TSR is off, then restored when it's back on. Elsewhere: a single audible warning.

Alert or Alert + auto braking mode, Low / Standard / High sensitivity. Mode buttons are greyed out while the system is off.

Turning the assist back on restores the last mode used. On SWI132: no emergency keeping, but two extra switches, audible warning and vibration.

The buttons express an intent, then the app re-reads the state 700 ms later and that reading decides which one lights up. Unreadable state = no button lit, rather than a guessed state. In a profile, ESC and drowsiness are only written if that profile configures them.

The card only shows on equipped trims: SWI69 and SWI131 (Standard/SE versions) as well as SWI132 don't display it.

Bounds vary between firmwares. While dragging, a single write is sent at the end, then the app re-reads the state 700 ms later. It never moves a slider under your finger.

While the screen is shown, the app follows changes made on the stock screen every 2 s. An unreadable state greys the button out rather than lying.

Each card shows the name, a summary (mode · regeneration · ADAS) and the DEFAULT badge, with Apply now, Edit, Set default and Delete (with confirmation).

The profile name and “default profile” stay visible at the top. Cancel / Save at the bottom; a name is required.

A profile never forces the unexpected: settings added over time (ESC, drowsiness, heating…) count as “not configured” in older profiles and are not written. So an old profile never disables ESC by omission.

Handy for a “motorway” profile that shouldn't switch off a seat already on.

The app checks the connected phones when the infotainment starts and every time the car switches to READY. Connecting a phone mid-trip applies nothing: its profile will apply at the next switch to READY. In the virtual vehicle, connect “Pixel 8” then simulate a start-up: the “Motorway” profile gets applied.

File MG4Control/mg4_profiles_backup.json in the vehicle's storage. On reinstall, if the app has no profile, a popup offers to restore them.

Presets at 15%, 50% and 100%. 5% floor: the screen can never be switched off by mistake.

That manual choice takes priority at the next ignition. The picker shows whatever the speed (it's also used for brightness); it's the write that gets filtered by the speed lock.

Without a choice before the countdown ends, the first one is applied.

They rely on the signal broadcast by the vehicle: if the stock launcher already uses that button, it keeps priority (e.g. 360° camera on single press). Disable the shortcut on the launcher side then.

Comfort and safety actions re-read the vehicle state on every press: an unreadable state means doing nothing, nothing is ever written blind.

One Pedal fallback regen: the level restored on the second press (High by default). ADAS alternation: the two modes the button toggles between (ACC ↔ Off by default).

Through it, MG4Control sees the key before the launcher and can consume it. The “Enable accessibility” button opens Android's service list and disappears once access is granted.

Any button whose press reaches the screen can be used. Its name and code show up (left ★ 17, right ★ 286, joystick 297 to 301…); a button with no known name shows its code (“Key 123”) and still works. Tapping the record button again cancels; the wait also times out on its own.

“All profiles” first in each group (display order is resolution order). Edit changes the action and the profile. The confirmation names the action about to be replaced.

• Garage mode, replacing the old automatic-application switch.
• External API, with explicit confirmation when enabling.
• Update check at launch, alert on the vehicle screen and beta channel.
• Power the vehicle off while keeping the screen on, and speed lock (0 to 250 km/h).

• Check for updates, Clean APK (old downloaded files).
• About: version, exact firmware, GitHub / GitLab QR codes, thanks.
• Data usage: today, this week, this month, last 30 days.
• Diagnostic, revealed by tapping the logo 5 times: a report to copy or download for bug reports.

The warning shows the raw detected version and offers Close the app or Continue. The chips in Settings → Info then become tappable; the choice is saved and survives restarts.

The stable release then replaces the latest beta of the same number, never the other way round. “Don't remind me” skips a given version.

Without Wi-Fi, a warning reminds you about 10 MB will go through the car's mobile data. Manual install is possible: QR code to the releases, a FAT32 USB stick and the file manager. The offline variant has neither network nor automatic updates.
