Can a smartphone be accessed only by knowing its IMEI?

Posted on October 25, 2017 by peter_s

I have an old smartphone that I want to use only as a media player/portable radio/voice recorder. It doesn’t have a SIM card and it’s not connected to WiFi. I am curious however can the files on it still be potentially accessed somehow? I know that a phone can be tracked with its IMEI number and according to this site – www.imei.info – you can “know such data as: the network and country from which your device originally comes from; warranty information ; date of purchase; carrier information; system version; device specification and more details information.” For the “system version” part, it seems to me that you have to have a pretty thorough access to the phone and possibly able to read the files on it; is this so or is this impossible?

Thanks in advance.

P.S. I read these topics – Can Android phone running without SIM card be tracked (localized) by police?, Track an Android phone through its IMEI, but they don’t answer this exact question.

What are the typical names of the Android (local)keystore file and its default locations?

Posted on February 23, 2017 by martin_s

A quick question from the novice Android dev. If an app uses local keystore where does it store that file and how is it named by default ? How would I determine it from the decompiled (smali) code ?
