[General Questions and Answers] Markd15:
As the title say, someone got into my phone.

Now, i am not a geek but I have learned some stuff throughout the years since I've been using Android. Recently I have recognized some new system apps on my phone which they were not installed by me. I did'nt panic, quickly removed my sd card erased all content and set it up as new phone. I did'nt signed into google play store or downloaded any apps, and I have kept my sd card out of the phone. So I just used the phone for text message, and calls. Just for fun (since I knew that I will erase all the content, I choosed to be a developer and started remove permissions from a lot of apps and soon enough I found something interesting in my download folder which was a pdf file, which you will see in a moment.

English is not my first language but I understood that it has someones report maybe generated I dont know. But I have a few questions.

What is this about?

Who might have been created this?

Who is that for? (Some kind of a report?)

Thanks a lot!
