Forum Thread: About Android Security!

So my mobile lcd got cracked and went to repair it , the guy told me it will take couple of days as the he already had my phone disassembled so i left it there, had a app lock on but still curious to know if someone copies data from your android device is there any way to find out some log or stuff which we can check if the data was copied from your device?

( Sorry if it sounds stupid to you )
