"Gyrometer" is an alternative term for gyroscope — used interchangeably in some phone repair contexts and manufacturer documentation to describe the MEMS rotational motion sensor that measures how fast and in which direction a phone is rotating around its three axes. The component, its failure modes, and its repair procedure are identical to those described under "gyroscope." In practice, every technician in Nairobi's repair market understands both terms to refer to the same sensor.
The gyrometer works continuously in the background of modern smartphone use: it stabilises video recording, powers augmented reality overlays, enables precise turn-by-turn navigation, and feeds motion data to gaming and fitness applications. On devices where it is fused with the accelerometer inside a combined IMU (Inertial Measurement Unit) chip, both sensors share a single BGA package on the motherboard.
Symptoms of Gyrometer Failure
- Screen rotation behaves erratically or fails to respond to device orientation changes
- Video recording shows shakiness that electronic stabilisation no longer corrects
- AR applications — Google Maps Live View, AR navigation, mobile games — misread or ignore physical rotation
- Navigation app compass arrow drifts or spins without corresponding real-world movement
- Sensor diagnostic applications report the gyrometer as missing, offline, or uncalibrated
- Symptoms developed after a hard drop, water exposure, or board-level repair
Always confirm via a sensor diagnostic app — available free on the Play Store and App Store — that the gyrometer is reading as hardware-absent before treating the fault as a repair job. Calibration drift can produce similar symptoms and is resolved through software without any part replacement.
Estimated Gyrometer Repair Costs in Nairobi (2024–2025)
| Device Category | Labour (KES) | Parts (KES) | Total Estimate (KES) |
|---|---|---|---|
| Budget Android — IMU chip (gyrometer + accelerometer) | 3,000 – 5,500 | 800 – 2,500 | 3,800 – 8,000 |
| Mid-range Android (Samsung A-series, Redmi, Motorola) | 3,500 – 7,000 | 1,200 – 3,500 | 4,700 – 10,500 |
| Samsung Galaxy S-series | 4,500 – 8,500 | 1,500 – 4,500 | 6,000 – 13,000 |
| iPhone (all models — combined IMU) | 4,500 – 9,000 | 1,500 – 4,500 | 6,000 – 13,500 |
| Google Pixel series | 4,500 – 8,500 | 1,500 – 4,000 | 6,000 – 12,500 |
Because the gyrometer and accelerometer share an IMU chip on most devices, a single chip replacement restores both sensors simultaneously — the cost does not double when both are faulty.
Post-Repair Calibration
IMU chip replacement requires post-installation calibration before the device is returned. Calibration confirms the sensor reads accurately across all three rotational axes under controlled movement conditions. Skipping this step can result in sensor drift that affects navigation and stabilisation performance.
Repair vs. Software Reset First
A factory reset or sensor recalibration tool resolves gyrometer drift in a meaningful proportion of cases. Exhaust software options before committing to a board-level repair — the diagnostic session to confirm a hardware fault costs KES 1,000–2,000 and is worth performing before any soldering work begins.
Pro-Logic Technologies at Kangari Building, Nairobi performs gyrometer diagnostics, IMU chip replacement, and post-installation calibration for all major phone brands and models.
