Cameras
| Lens | Facing | Focal length | Sensor size | Max res | Modes | HW level |
|---|---|---|---|---|---|---|
| Rear #0 | BACK | 26mm (2.38mm) | 3.2 × 2.4 mm | 1440×1080 | 13 | LEGACY |
| Front #1 | FRONT | 26mm (2.38mm) | 3.19 × 2.4 mm | 1280×960 | 8 | LEGACY |
Focal lengths show the 35mm equivalent first; the sensor's native focal length is in parentheses. Only the equivalent is comparable between phones.
Max res is the largest frame this lens was proven to record: a real clip written to disk and read back with frames in it.
Encoder frame ceilings
| Codec | Largest frame | Macroblocks | Advertised max |
|---|---|---|---|
| AVC | 4096×2304 | 36,864 |
One macroblock is 16×16 pixels. The macroblock count is the encoder's real ceiling — a budget every frame has to fit, landscape or portrait — and the largest frame beside it is simply the biggest shape that spends it. The advertised maximum width and height are struck through where their product exceeds that budget. They are independent limits that cannot be used together, so the figure they imply is not a resolution this encoder will accept: design against the macroblock count, not the advertised pair.
