v5.0.15

• Samsung A / wide-FOV cameras: face is no longer rejected as "Move closer" at any distance
• Hairline outside the ROI circle now blocks capture (was passing as valid)
• "Move closer" / "Move slightly back" messages now actually show on screen
• Low-RAM devices: bitmap OOM shows "Retake photo" instead of crashing
• Retake no longer leaves old capture files in cache
