If you want to protect your privacy from malicious Android applications that try to spy on you, get a privacy slider for your camera. My privacy slider fits in a tight spot on the front of my Google Pixel 3a XL smartphone and does not bother my right ear at all. Do note that the privacy slider won't work with smartphones with a notch or a screen with a cutout for a camera. Of course, it's better that you only download apps that you need and avoid apps that can contain ads that make use of the camera.Today, my privacy slider came off of my smartphone, so I might have to dock 1 star for adhesion and I don't know what I did with it. At least I have a couple of privacy sliders left.Update as of October 30: My second privacy slider started to wear off for my smartphone. I might just use another one until all the privacy sliders wear off and I might have to spend more money for a better one.Made sure surfaces were squeaky clean but these things still keep coming off. Tried to use on my phone’s front camera (iPhone XR) but hard to apply a good fit or use if you have a case. Between that and constantly pulling the phone in and out of my purse or pocket, these covers would come off in a few days. Same with iPad. It was easier to center the placement on the iPad but again, would only last a week or two before I realized it was missing and I would find the cover in my bag or on the couch, etc. it seems to be the adhesive. You can tell when it starts to loosen, because when you try to open or close the cover the placement moves a little. Now I know why so many came in a pack, you’re constantly having to replace them. However, works great on my desktop monitor - because it’s stable and the cover doesn’t get used, it stays closed. So for that, an extra star.Just that they keep coming offWorks very well - but be gentle with the slide - it can pop off if you're gruff. I put a four for adhesion, but actually, when the slide popped out, it was a good thing! And the transition when the camera in the laptop goes from the slide to me or behind me is pretty cool too. And this may be all that stands between you and a serious loss of privacy - long live the 4th Amendment!This device is Almost perfect!!!Easy to install. Easy to operate. It stays in place and covers the camera lens perfectly!My only complaint is the sliding cover is easy to pop out. I have it on my cell phone and I've lost a cover or two. Thankfully I purchased a larger pack than I needed (replacements in case of problems) and I can easily put a new slider in. If they can fix that problem, these would be perfect! Still a Great purchase for the price though! :) Highly Recommend!!!perfect in all respects in my opinion. cheap little shutters, exactly as expected. not hard to install. not too sticky nor too little stickiness. just perfect. little slider has just the right resistance in my opinion. these are disposable shutters. i expect to buy another package just like this when i want more. perfect for me!Very cool product... they fall off after about a month tho... but other then that works really wellSometimes I open my laptop and the part that covers my camera has somehow slid to the right exposing my cam on my laptop. Not sure if its just the one I have on my laptop because im the only one experiencing it from my sisters and we all have the same covers that i purchased for us. They stick well no issues there but I might just have to replace mine with another one from my packet that I got. Other than that they work well!
