System Optimizer Customer Insights

1. This is why majority of all apps don't get cookies and are blocked from using data cookies.Why is this keeps telling me to download this app and even if theres a cancel button it cant be cancel it gives me headache that my important things to do in chrome cannot be done then when i download it chrome didnt detect it it wants to download it againIt shows that my phone temperature is 38 degree, after cool down it turns into 25 degree in just a second.

2. I generally pay for premium versions of apps I use but this evaluation version won't get that far with meI'm not angry right now... I'm f__kin pissed off you developers should be proud of yourselves coz this thing ruined my entire day I can't even access the internet without seing that pop up and now my phone has crashed and I have your app to thank for that... thank you That pop up doesn't go away, it fills up my entire screen even after hitting "install" my phone crashes and I have to restart it and the same thing happens over and over againScrew this- I'm done.

3. They make damn sure you know your can buy the app on EVERY SCREEN after showing you ANOTHER AD AFTER EVERY TAP!Nice to use this app coz I'm often using this, only when times my phone was lag and my phone battery🔋will decreases it's power even I'm charging it coz it needed to be optimize and that's the time I use the system optimizer as well as the other functions of it.Nice and simple to use, I believe that it works well at cleaning and optimizing and I think that it is definitely worth installing on your tablet or smartphone.It's fair sometimes but not all of the time.

4. I managed to get trough and erese whole phone, but can't tell you how as optimizer app are probably work with that antivirus app that ask you to install too.When i was trying to download files, a pop up came saying ( update you android cleaner.....) they hav 2 option either install or cancel.

5. Worning!!! this app is let you install a malwer virus that will take control of your phone settings and collect all payment information and loging details by transferring you to different page of original.

6. Tried this POS again and see they list "can show ads" as a threat for other apps but continue to consistently SPAM you! RIDICULOUS ADS!!! Jesus Tapdancing Christ! This is an ad delivery platform with an occasional function.

7. Press the three dots on top and select flag as inappropriate.I don't have a problem with ads but a 30 second video that plays (every time) before you can open is so intrusive I was unable to evaluate the app for what it is supposed to do.

8. Dont download this kinda of apps which unnecessary force u to download.

9. UPDATE: Airplane mode prevents these stupid ads from spamming your phone.

10. I clicked on cancel but it is still redirecting to this app in play store ( same thing continued for 4, 5 times).

11. None of trusted apps do this kind of thing.
