i have a Motorola L6. the Camera takes pictures of 640x480 and the average size is from 90kb-110kb. i compared it to other phones (motoL7, n6600, motoC261) it its almost double their size with the same resolution which averages from 50kb to 60kb. i want to save space from my memory. what should i do? is there some settings i need to modify? i dont want to decrease the resolution. i still want it to take 640x480 resolution.

You might need to have it serviced.

does your phone take a memory card, if so that may be your best option. you can't make pics have less memory until you change the resolution before the snap
