title: Android volley library doesn't keeping good quality image
body: <p>I am using volley library to download image from network and to retain image in cache for later usage. volley is serving all my need.but the strange behavior is, it keeps good quality image based on the network speed , what surprised me is that, in 2G network it keeps poor quality image but in WI-Fi, it keeps very good quality. i am stuck here to find out root cause of this behavior. if you have faced this problem before , please share your knowledge what is happening in library, why it behaving differently on different speed, how i can keep same quality irrespective of any speed.</p>
  
  <p>Thanks</p>
