[Android Apps and Games] dicksteele:
I've reread from the beginning and you have never stated model of phone. And not sure where you uploading bug reports and screenshots. It's not in this thread.

Since you have an S5, The Android N Developer Preview is available for Pixel C, Nexus 6P, Nexus 6, Nexus 9 and Nexus 5X.

I'm not sure you are going to find any legal precedence to do anything against anyone who had possession of your phone with your knowledge.

Personally I think you are overacting. But before you go off the rails, on a rant that I'm not helping.

My opinion of you overacting is based on your short term research. Yes there are things possible, but again highly unlikely.

Again, in my opinion your phone has not been hacked. You stated you knew someone had your phone. Someone installed applications on it, and the most possible way is, through the Google Play Store or through Samsung Apps. Which require accounts.....

It takes more knowledge to install them, which would require root access, manually.

From Wikipedia (not saying it's gospel) I don't know where you live, don't want to, but this "should" be reference enough regarding rooting in the US

United States

Under the Digital Millennium Copyright Act (DMCA) rooting is illegal in the United States except by exemption. The U.S. Copyright Office currently grants phones an exemption to this law "at least through 2015".[41]

In 2010, in response to a request by the Electronic Frontier Foundation, the U.S. Copyright Office explicitly recognized an exemption to the DMCA to permit rooting.[42][43] In their ruling, the Library of Congress affirmed on July 26, 2010 that rooting is exempt from DMCA rules with respect to circumventing digital locks. DMCA exemptions must be reviewed and renewed every three years or else they expire.

On October 28, 2012, the US Copyright Office updated their exemption policies. The rooting of smartphones continues to be legal "where circumvention is accomplished for the sole purpose of enabling interoperability of [lawfully obtained software] applications with computer programs on the telephone handset." However, the U.S. Copyright office refused to extend this exemption to tablets, arguing that the term "tablets" is broad and ill-defined, and an exemption to this class of devices could have unintended side effects.[44][45][46] The Copyright Office also renewed the 2010 exemption for unofficially unlocking phones to use them on unapproved carriers, but restricted this exemption to phones purchased before January 26, 2013.[45]

Tim Wu, a professor at Columbia Law School, argued in 2007 that jailbreaking is "legal, ethical, and just plain fun."[47] Wu cited an explicit exemption issued by the Library of Congress in 2006 for personal unlocking, which notes that locks "are used by wireless carriers to limit the ability of subscribers to switch to other carriers, a business decision that has nothing whatsoever to do with the interests protected by copyright" and thus do not implicate the DMCA.[48] Wu did not claim that this exemption applies to those who help others unlock a device or "traffic" in software to do so.[47] In 2010 and 2012, the U.S. Copyright Office approved exemptions to the DMCA that allow users to root their devices legally.[49] It is still possible to employ technical countermeasures to prevent rooting or prevent rooted phones from functioning.[50] It is also unclear whether it is legal to traffic in the tools used to make rooting easy.[50]

At minimum from what have experienced and understand, you root you're phone you void your warranty. From what I have read from people that have jacked up there phone from rooting or a process that was available because it was rooted, they just got a new phone.

Myself included.

Based on what you have written, again I believe you are overacting without personally looking at the phone. Some of the apps and files you describe, some are the base software. libstagefright, libaudio, whatever are part of the Android operating system.

Camera, clock apps etc. are easily installed, with an account on Google or Samsung App stores. Now is it illegal from someone that has physical possession of your phone to install an account on there to install apps.... Don't know, probably not. But malicious intent would have to be proven I imagine.

Also based on what read, I said I believe you are overreacting.

But this statement --->"So, i am now playing with scorching hot fire to beat the clock and get answers b4 something happens to not only the files and info i carry with me, but i have become afraid of what might happen to me, as well"

I'm not sure what this means.

I'm not trying to diminish or ignore your concerns.

BUT

Since you say you know who had the phone, and hopefully I have made you understand that anything on it, had to be done with the phone in their possession, my suggestion is YOU stop messing with it and take it someone qualified to investigate what is on it.

The very first thing that is done is make an exact copy of it.

If you are not going to do that, not sure how far you are going to get with what you seek.

How to find accounts that were used to install apps

If the account is not on your phone, without it, proving what was installed is difficult. Google keeps a record. Logging into the account will show what was installed and when. But only with the account name and password.

BUT AGAIN

The more you mess with it, the less chances there are to "prove" the purpose or intent of the person that had YOUR phone, installing these apps.
