LagFix (fstrim) Trimmer

The reason for the 4 is because I just didn't notice any difference with the phone lag. Another reason is that when I use the application, right away a advertisement comes on which I understand but...There's no way to exit out from the advertisement. I had to completely close the application to get out of the application and that annoys me

Fixed my Nexus 7 using this. It was difficult trying to find the cause of the slowness but this clearly showed a fix after running it. If it didn't fix it you cannot simply blame this app because the cause might be something else not flash memory related. Thank you.

It's really helpful! Now, my annoying Samsung Tab-E gets faster whenever i press the trim button. Now I can play minecraft without lag. I don't know how does it remove lags from the device, but I loved it!!😊

Maybe it's a placebo effect, but after running it the phone seems speedier. It's only missing an automatic (or scheduling) feature or a Tasker plugin to be perfect.

It works really well, i highly recommend you to use this app, it does its job, I haven't seen that much ads , however I'd rate it 5 stars but it only lasts for about 6 minutes i have to get back to the app so that my game wouldn't lag, but overall it's really good it works you should try this app, trust me it works well.

Seems to work on a somewhat temporary basis, but negotiating a way out of the adverts is a pain in the **** When I tap the back button, I expect it to work, not be crippled by this type of coding. Agreed everyone has to make a dollar but that's not an unreasonable expectation. The fact is this app coupled with freezing *anything* related to Google Play has returned my Nexus 7 2012 to a useable status. Like Google Gs-A-S about the mess they created. Shame on them. Thumbs up for this app then.

Not sure if it worked yet, seems to have though. The loss of three stars is due to the absolutely obnoxious ad frequency.

Almost perfect, does what it's suppose to do almost. Not bad compared to the other 2 " error failed " apps.

This is a true booster and lag fix. No frills, no bells and whistles, and no hype, its just exactly what it claims to be.

Not sure what this app did but video lag with Bluetooth is no longer an issue. Thank you!

Yeah it is temperory. but, its boosted the performance a lot. You can re boost before playing. It takes less than a minute to boost

At first i thought it was a good app but the more you use the app the more your phone losses it features.. AND THAT IS NOT GOOD, I would rather use my phone a bit laggy than lossing very important features!

Doesn't do anything. Didn't notice any difference on my s9 plus. Also, may I suggest banner ads on the bottom instead of those multiple annoying popup ads. For these reasons I am uninstalling.

It actually works! At first I had doubts about it working but when I used the app all of a sudden my phone when so smooth. Thank you whoever made this app! You have made my day😄😄😄

i was looking for a anti lag to fix my roblox game on a CHROMEBOOK and so i found this app and it ACTUALLY makes my game 57% smoother on ROBLOX MY RESTAURANT, like the app is able to hold and manage to smoothen my device. I recommand this app

If you are a gamer or have low spec phone i recommend this app is the best to fix it my phone is not even 1 GB RAM and lag even in my daily usage but after this app it work more better thanks developers for making this dont let its simple interface trick u because is so infectable best ;)

This app is perfect for low end device...like me it really remove lag such an slow response and glitching not sure about the glitching but my phone its not glitching anymore

HOLY GOD!! THIS APP IS REALL OG!! This app totally clean every cache and data that i couldn't clean before, my phone lags even if i coc or minecraft now it made my phone run smoothly as a butter I love it!

Best lag fix EVER. I was plying pubg and my screen just wont handle it. Until i discovered this app. THIS IS THE BEST LAG FIXER EVER! I recommend you downloading this.

One hundred present working because I play pubg lite and it always lag and ping always bad but when I saw the five star reviews on the app I check it out and it works it made my game stop lagging and it free up my apps and other games I'm using a : ZTE BLADE A3 2020 VERSION 9

Love it, does as it says and even allowed my other apps to run and make the screen pop with color. Thank you for something easy to use and does what it says

It does reduce the lag that does not mean it's gonna fully fix your lag but it's work that's why i am giving 5 star to this app

I have no idea if this works . Because my phone UI is very fast... I will drop a better review later

lt seems to work. It's strength lies in it's simplicity and ease of functionality.

Saved a Nexus 7 I was about to throw in the trash! Darn old-school nand based memory and an Android old OS bug. I wonder if this would help on my TF700T...?

How do i reverse its effect my phone is heating while playing pubg for just 5 minutes now, and it starts to heat after playing 1 hour before using this app, help me to reverse its effect.
