Samsung Galaxy S24 Ultra Error Camera Failed - 50MP Telephoto OIS Coil Short: 50MP Telephoto OIS Coil Short
The camera application terminates with a 'Warning: Camera Failed' popup due to the internal camera driver IC detecting an overcurrent condition or low impedance on the 50MP periscope telephoto Optical Image Stabilization (OIS) Voice Coil Motor (VCM) drive lines, tripping hardware overcurrent protection.

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) |

Common Symptoms & Fault Manifestations
- Stock Camera application crashes immediately when switching to 5x optical zoom or beyond
- 'Warning: Camera Failed' modal dialog displayed upon initialization
- Audible mechanical rattle or high-frequency buzzing originating from the upper periscope telephoto module
- Failure in Samsung Service Menu (*#0*#) during Mega Cam or Telephoto sensor test execution
Root Causes & System Failure Modes
Mechanical shock/drop impact causing physical deformation and enamel insulation breakdown on the OIS VCM suspension coils (< 5 Ohms nominal resistance)
Short circuit or solder bridge across the OIS driver VDD/OUT lines on the camera module flex FPC
Blown or shorted bypass filtering capacitors on the sub-PMIC telephoto power rail (VDD_CAM_OIS_3P3V)
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
Safe Isolation & Disassembly
Power off the Galaxy S24 Ultra completely. Heat the back glass panel at 80°C for 5 minutes using a thermal mat. Use an suction cup and plastic pick to slice adhesive along the perimeter. Unscrew wireless charging coil/NFC assembly bracket screws, disconnect the battery interconnector immediately to cut all live VDD lines.
Physical & Multimeter Impedance Inspection
Disconnect the 50MP periscope telephoto camera module FPC. Inspect the connector header under magnification for bent pins or debris. Set multimeter to resistance mode; probe the differential OIS voice coil driver pins on the disconnected module FPC. Expected nominal coil resistance is 10–18 Ohms. A reading below 4 Ohms confirms an internal short circuit in the actuator coil.
Module Replacement & Board Level Verification
Because internal periscope voice coils are hermetically sealed and micro-wound, a shorted coil requires complete replacement of the 50MP 5x periscope telephoto camera assembly (OEM Part). Before installing the replacement module, verify that the motherboard camera connector pin VDD_CAM_OIS_3P3V is not shorted to ground (diode mode forward drop approx. 0.45V–0.55V).
Recalibration & Verification
Reconnect the new telephoto module, secure mainboard brackets, and reconnect battery. Power on and enter hardware diagnostics via *#0*# in the dialer. Select 'Mega Cam' and toggle to the telephoto (5x/50MP) module. Confirm smooth AF/OIS actuation, clear autofocus locks, and verify that the 'Camera Failed' error is resolved without crash logs.
Hardware Reset & Fault Clear Sequence
Controller ProcedurePrevention & Routine Maintenance Guidelines
- Avoid exposing the device to extreme drops or continuous high-frequency vibrations (e.g., rigid motorcycle handlebars) without vibration dampeners
- Always disconnect the primary battery connection prior to unseating or reconnecting camera FPC ribbon cables to prevent coil driver surge shorts
Frequently Asked Diagnostic Questions
What does error code Camera Failed - 50MP Telephoto OIS Coil Short indicate on Samsung Galaxy S24 Ultra?
The camera application terminates with a 'Warning: Camera Failed' popup due to the internal camera driver IC detecting an overcurrent condition or low impedance on the 50MP periscope telephoto Optical Image Stabilization (OIS) Voice Coil Motor (VCM) drive lines, tripping hardware overcurrent protection. In engineering telemetry, it indicates 50mp telephoto ois coil short requiring circuit verification.
What are the primary triggers causing error Camera Failed - 50MP Telephoto OIS Coil Short?
Diagnostic bench telemetry isolates the following common root causes: Mechanical shock/drop impact causing physical deformation and enamel insulation breakdown on the OIS VCM suspension coils (< 5 Ohms nominal resistance); Short circuit or solder bridge across the OIS driver VDD/OUT lines on the camera module flex FPC; Blown or shorted bypass filtering capacitors on the sub-PMIC telephoto power rail (VDD_CAM_OIS_3P3V).
How do I reset and clear Samsung error Camera Failed - 50MP Telephoto OIS Coil Short?
Clear camera cache and data via Settings > Apps > Camera > Storage > Clear Data. Next, wipe the system cache partition via Android Recovery Menu (Hold Volume Up + Power connected to PC via USB). If the error status repeats immediately after clearing, discontinue clearing and test circuit continuity.
Can I safely resolve error Camera Failed - 50MP Telephoto OIS Coil Short 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.
