Comparing opera mini to facebook lite now, opera mini is consuming a lot of data in the "normal saving mode". The way to make it save some real data is to activate the "extreme mode" which has bad interface compared to the facebook lite. So now it become not reasonable to work with opea mini as Facebook lite make the real deal (saving data, good interface).
My suggestion is adding a new image qualiy option with lower quality than the existing ones or lower resolution, like " extra low quality" or something in the "normal saving mode" so it could compete with Facebook lite.
Thanks a lot for your efforts.
