How to clean up memory on your Android phone
Yesterday my Android phone started complaining about low memory. A quick check gave me Navigon of course as a main consumer of space. 26mb and it refuses to shift to the SD card. It wasn't the top scorer though, that was contacts storage.
Some further investigation gave me http://android.appstorm.net/how-to/clear-space-without-rooting/ with some good step by step information on how to handle that.
While creating a backup of my gmail contacts I noticed that there were 2100 of them. Now I don't even know 210 people let alone 2100. So I dug into gmail and it seems it's added everyone I ever mailed to my contacts.
Anyway, using the instructions above I managed to shrink my contacts storage to 424 kb.
