Smart Booster Customer Insights

1. Hats off to the developer for this one.Widget not show up on my vivo phone cuz my camera is at the middle of my notification bar...i had this app installed on my other phone, so that's how i know the widget is placed at non-existence place! Even on notification, it shows just a notifcation and my phone keep beeping every few seconds cuz the app give notification instead of placing the widget in thereSmart booster not so smart afterall .. in fact its misleading.

2. I am mainly interested in cache cleaners, creating more RAM, and having a longer use of battery.I've tested some apps such as Max battery or duraspeed(my nougat builtin) but even the dura was consuming more battery also max having conflict and heavy repeated animations making it worse.

3. it 'hibernate' apps by making the user to click on 'force stop' on the system page .. when first time opening the app it hangs twice .. 3rd time finally it starts.

4. And the feature to select auto boost and the level of boost as strong/extreme/gentle/mediocre is amazing.Doesn't work correctly after last update.

5. Who knows.I opened up a bunch of apps to see if that would work since it was showing no apps were open.

6. It is a must have appOne tap bar doesn't shows up tried cahnging transparency and allowing permissions But no luck on Realme Narzo 30A.

7. Ow and another note it has an accurate permission manager.I've downloaded and have tested too many boosters, cleaners, and optimizers to count, and by far this one is one of the best, even on a low-end RAM device like mine.

8. Please fix! This app has been great up until now!Thought I would try this, so many of these RAM cleaner apps don't function right, but this one actually works.

9. Smart boost was the only one app with good capabilities of saving both ram and battey(cpu concludly) for my blu grnd m2.

10. The critical feedback should by no means be the deciding factor in trhing this app, because as far as I can tell the critical opinions are more for astetics reason than actual performance.

11. The widgets no longer work, most just lock up the phone then the app crashes.
