The 3G to 4G Speedup application unlocks hidden features in your mobile phones which are present in 94% of devices since 2012. Vendors lock this functionality to sell more expensive phones but actually use the same chipset as the more expensive 4G phones. Most of the competing 4G conversion software require you to do hardware modifications using a soldering iron and sometimes an extra chip. This software ABSOLUTELY does not require any hardware modifications because everything is simulated. Why choose ControllX 3G to 4G Speedup? - It's free. No unwanted permissions needed (secure. ) - You can see the speed gain in action- Easy uninstall (no parameters stay in the settings) - No hardware modifications- It's an awesome simulation. There are programs out there that gave Internet optimizers a bad name. ControllX 3G to 4G is different. We do not lie about the true nature of this application. it is not real and is meant to be used as a joke app to fool people. It really looks real and it works on most Android versions (even if you don't even have 3G).
