Samsung Galaxy S24 Ultra Error CAM-OIS-BANDING-5X: Telephoto OIS Failure Banding
Voice coil motor (VCM) or Hall sensor feedback failure inside the 5x/10x periscope telephoto module causes high-frequency mechanical oscillation, inducing horizontal CMOS sensor rolling shutter banding and triggering firmware safety shutdown.

Multimeter Probing Targets & Circuit Tolerances
Bench Calibrated ±5%| Test Point / Circuit | Target Nominal Spec | Expected State | Fault Condition |
|---|---|---|---|
| Main Logic DC Bus | 3.3V / 5.0V DC (±0.1V) | Stable DC Potential | <2.9V (Brownout / Sag) |
| Thermistor / NTC Sensor | 10kΩ - 100kΩ @ 25°C | Smooth Thermal Curve | 0Ω (Short) or ∞ (Open) |
| Safety Ground / PE Continuity | < 0.5Ω Resistance | Solid Earth Bond | > 1.0Ω (Floating Chassis) |
Common Symptoms & Fault Manifestations
- Stock Camera app crashes with 'Warning: Camera Failed' pop-up when switching to 5x zoom
- Visible high-frequency mechanical buzzing or vibrating noise from upper periscope prism housing
- Horizontal flickering lines and rolling shutter banding artifacts on screen right before app termination
Root Causes & System Failure Modes
Voice Coil Motor (VCM) driver IC PWM control line short or open circuit on the telephoto flex circuit
Failed or cracked periscope ball-bearing track causing prism binding and Hall sensor feedback runaway (draws >350mA overcurrent)
Damaged or cold solder joint on MIPI CSI-2 differential signal pairs / PMIC VDD_CAM_2P8 low-dropout regulator rail
High-Voltage & Mechanical Safety Isolation
Prior to opening access panels, disconnecting terminals, or probing wiring, perform complete lock-out / tag-out (LOTO). Disconnect all AC mains, DC string isolators, and lithium battery banks. Allow internal smoothing capacitors at least 3 to 5 minutes to dissipate stored residual energy below safe threshold (<30VDC).
Step-by-Step Diagnostic & Resolution Procedure
Diagnostics & Factory Mode Isolation
Dial *#0*# in Phone dialer, select 'MEGA CAM' and cycle to sub-telephoto lenses. Verify if the 5x periscope throws an OIS Init Fail or Read Hall Sensor error before disassembling.
Device Teardown & Power Isolation
Power down phone completely. Soften back glass adhesive at 80°C for 5 minutes. Remove rear panel, disconnect the battery connector immediately, and remove the wireless charging coil/NFC shield bracket.
FPCB Inspection & Rail Voltage Measurement
Under a microscope, disconnect the 50MP 5x periscope telephoto module FPC. Inspect for torn flex traces. Measure passive continuity to ground. Reconnect power temporarily to verify VDD_OIS_3P0 (3.0V) and VDD_CAM_1P8 (1.8V) supply lines at decoupling capacitors.
Module Replacement & Optical Recalibration
Replace the damaged periscope camera module assembly (Part # GH96-16606A). Reseat camera FPC firmly, reassemble midframe and battery. Power on, open dialer, run *#0*# Camera Calibrate (Dual/Tele Calibration) to match new Hall sensor drift values with the ISP.
Hardware Reset & Fault Clear Sequence
Controller ProcedurePrevention & Routine Maintenance Guidelines
- Avoid high-vibration environments like motorcycle handlebar mounts without active vibration dampeners
- Protect device from high kinetic drop impacts on corners adjacent to the top-right camera island
Frequently Asked Diagnostic Questions
What does error code CAM-OIS-BANDING-5X indicate on Samsung Galaxy S24 Ultra?
Voice coil motor (VCM) or Hall sensor feedback failure inside the 5x/10x periscope telephoto module causes high-frequency mechanical oscillation, inducing horizontal CMOS sensor rolling shutter banding and triggering firmware safety shutdown. In engineering telemetry, it indicates telephoto ois failure banding requiring circuit verification.
What are the primary triggers causing error CAM-OIS-BANDING-5X?
Diagnostic bench telemetry isolates the following common root causes: Voice Coil Motor (VCM) driver IC PWM control line short or open circuit on the telephoto flex circuit; Failed or cracked periscope ball-bearing track causing prism binding and Hall sensor feedback runaway (draws >350mA overcurrent); Damaged or cold solder joint on MIPI CSI-2 differential signal pairs / PMIC VDD_CAM_2P8 low-dropout regulator rail.
How do I reset and clear Samsung error CAM-OIS-BANDING-5X?
Navigate to Settings > Apps > Camera > Storage > Clear Data and Clear Cache. Next, wipe cache partition via Recovery Mode (Volume Up + Power with USB connected to PC). If the error status repeats immediately after clearing, discontinue clearing and test circuit continuity.
Can I safely resolve error CAM-OIS-BANDING-5X without specialized shop tooling?
This fault is graded as Advanced difficulty with High severity. Standard diagnostics require an insulated digital multimeter and appropriate hand tools. Always observe high-voltage isolation procedures.
