Hello Community,
I was just clearing up my (Android) phone and when I was looking in the downloads folder there is an Adobe Acrobat folder and inside of it is a random file I couldn't imagine I've downloaded its name is 'ChandlerIncidentReview.pdf' no a single clue how it got on my phone, I opened it and its a bunch of scanned documents from the Chandler Police Department. The document is about this case. How would it had gotten on my phone?

Brief note on tracing and handling a stray PDF (for ): this is a fairly common puzzle and there are simple, reliable steps to both find out how it arrived and make the phone safe.

  1. Check timestamps and origin: open your Files/Downloads app, long‑press the PDF → Details to see creation/modified time and full path. That timestamp is the best clue for where to look next.
  2. Look where files normally come from: check your mobile browser’s Downloads/History, your email app (search for PDF attachments), and recent chats in messaging apps. Also open the Acrobat app’s “Recent” view — it often shows the source app. This follows @gusano79’s suggestion about a browser preloading a file.
  3. Don’t assume danger, but be cautious: if you didn’t explicitly download it, avoid re‑opening the file. If you’ve already opened it, still run a scan with a reputable mobile security tool and/or upload the file to an online scanner from a desktop.
  4. If you want to remove it: delete the file from Downloads, then clear your browser or app cache, and check Settings → Apps for any recently installed or unfamiliar apps (revoke storage permissions or uninstall anything suspicious). Also verify Device Admin apps in Settings → Security.

If there are further signs of compromise (unexpected battery drain, unknown apps, popups or credit card activity), backup important data and consider a factory reset. Otherwise, the most likely explanations are a clicked link, an email/messaging attachment, or a cloud/document viewer saving a local copy — all benign but worth verifying. ’s caution about not opening unknown files is sound; treat unknown attachments carefully until you can confirm their source.

Hm. Perhaps an overzealous browser pre-loaded it for you from a link on a page you visited?

Yeah probably

Remove it. DO NOT OPEN IT! It may well be malware, ready to infect your system if you open it. I don't know, but as the saying goes, better safe than sorry!
