I am very pleased with the Spark, except for:

I don't undertand why if Spark has better CMOS than Iphone 7, it can only record videos in a resolution of 1080 and it can take selfies snapshots of 1440x1080.

Iphone 7 records videos of 4K and  in 1080 p slow motion.

In addition, the front camera takes pictures of 7 Mpx

It would be good if Spark improves its performance characteristics:
- Video Resolution
- 2k 24/25 p
- FHD: 1920 x 1080 24/25/30/48/50/60/96p
- Image size, selfie
- 12 Mpx

Estoy encantado con el Spark, excepto por:

No entiendo como el Spark teniendo mejor CMOS que el iPhone 7 solo capture vídeo a 1080 p y tome instantáneas en modo selfiel a 1440X1080

El iPhone 7 graba vídeo a 4 K   y también captura video a cámara lenta en 1080 p.

Incluso la cámara frontal toma fotografías selfie a 7 Mpx

Estaría bien que el Spark ampliara sus características como mínimo a:

Video Resolución

- 2 K 24/25 p

- FHD 1920x1080 24/25/30/48/50/60/96 p

- imagen en modo selfie 12 Mpx

Its not all bout the size of the sensor, but also the processing power that is required to record at higher resolutions.
