1. honestly, it is the only amplifying app that works even some of the time, but that doesn't excuse it.it used to work really well on my Bluetooth wireless speaker then suddenly quit working I even updated to 2019 version from the 2017 version it still does not work right it should work on cordless Bluetooth speakers as well as external and internal speakerswhen I started using volume amplifier booster, it worked well enough but it got weaker as time went on ! Because of my medical condition, I have hearing problems and now it sounds like a whisper!Started off working nicely....then stopped and then started again....and now it's intermittent.
2. volume is not noticeable, it's almost as equivalent to the default sound of the phoneThis is some amazing shut your mouth shut the front door it is amazing I like it my phone is super loud now don't get to messing with the settings cuz you will distort some things and it will be terrible but otherwise than that you will have the loudest phone in the building so be careful what you feel in the night before you just might be putting your business loudly out thereExcellent app.
3. Wasn't getting much sound from the tiny speaker provided by my Airbnb, with my volume turned to max.
4. I was not able to hear my phone ringing even at the loudest volume.
5. ....stops working so I crank up the volume and then it blows my ears away and then stops again....not bad, but there's a lot that needs to be improved.
6. I proudly recommend everyone to use this Volume Amplifier Booster app 'cus it's the best👍.
7. I run Android 4.2.2 on my old tablet and the sound was terrible.
8. Now the boost makes my speaker almost growl!! No problem at all!😂Worked perfectly.
9. After installing, when maxed managed to get a complaint neighbour's.its very effective and works very well on Puxel.
10. It was also difficult to hear the caller's voice when speaking.
11. It's awesomesometimes it will stay on for hours, other times it will turn off about every 3 minutes just to make you see ads.
