What This App Is Supposed To Do
QR Scanner from P & L Studio is a free Android utility for reading QR codes, generating your own codes, scanning product barcodes, and even pulling data off the machine-readable zone of IDs and passports. It keeps a history log of everything you scan or create, so you don’t have to rescan the same code twice. On paper it targets anyone who needs a quick, no-fuss scanner rather than a bloated multi-tool, which is exactly the niche that made it popular enough to rack up over 31 million installs.
What Long-Time Users Say Worked Well
Several reviewers who stuck with the app for years describe it as fast and reliable in its earlier form: point the camera at a code and it scans instantly, no button presses or zoom adjustments needed, matching the store description. One user specifically said they had it installed for about a decade with no problems and never saw an ad, which suggests the core scanning engine itself has historically been solid and quick once it loads.
The Ad Problem That Dominates Recent Feedback
The most consistent and heavily upvoted complaints are about advertising. Multiple users report that a recent update buried the app in ads to the point where they can’t see scan results, can’t start the app, or the ads open instead of the scanned link. One reviewer scanned a barcode and never got results at all because ads blocked the screen. Another explicitly said they don’t mind ad-supported apps in principle, but here the ads have overtaken usability entirely. This is not a minor annoyance in the reviews — it’s the dominant theme among the most helpful ones.
System-Level Complaints Beyond Just Ads
Beyond intrusive ads, some reviewers describe more alarming behavior: the app allegedly changed home screen layouts, removed frequently used apps, and became difficult or impossible to uninstall. Others claim it’s being promoted through deceptive advertising that falsely tells users their existing QR scanner is outdated. One review went as far as calling it spyware and urging immediate deletion. These are serious accusations that go well beyond typical ad fatigue and point to real trust issues with how this app behaves post-update.
Who Should Actually Download This
If you just want a barebones scanner and are willing to grant camera permissions to something with a checkered recent reputation, the core scanning and barcode/passport features do sound genuinely useful based on the feature list and older reviews. But given the volume of recent complaints about aggressive ads, broken link handling, and alleged system interference, this is hard to recommend right now. Anyone considering it should watch for excessive permission requests, be ready to uninstall if ads become unmanageable, and consider that the version currently being distributed may not match the smooth experience longtime users originally praised. Users prioritizing a clean, ad-light experience should probably look elsewhere until these issues are addressed.
