I bought an S2 a few months ago originally for my business. One day I decided to try it out. I loved it because of the bigger screen but had issues right away. Cruisin 200ft up less than 500ft out my video became grainy, blotchy and sometimes had a wavy ,blurry look. I thought initially I had video feed issues. On playback it was totally fine. I'm currently flying a wifi only iPad mini 2. Plenty big and runs flawless but do miss android. Is there a setting in my S2 I'm forgetting? Or do u think the processor may be too slow? Just would like to have a "second option" encase my iPad ever had an issue . Do I need to fly wifi on? With S2 do I leave data and wifi on or wifi and airplane mode? Thank u for any help.
