[Motorola Droid RAZR] Ohmster:
Google Voice does not work by overclocking. Each device developer tweaks the rom for the device he is assigned to. Stargo, our developer, had to bump up the minimum CPU Frequency on Razr phones to 600MHz when running Voice to make up for the audio drivers we use. He does not have the source code for the drivers because it is proprietary so he uses the old Jellybean drivers with a Kit Kat wrapper around them. Not very efficient but the best he can do.

* A Razr phone runs at a maximum of 1,200 MHz and slows down to 300 MHz at idle in 5 steps, depending on how busy the phone is.

The feature is simply not in the Google app anymore, except when you run the app by hand. Google took it out, you cannot "enable" something that is not there. Why the took it out, I don't know. Probably because it is not as good as they want it to be. Voice is no match for Siri on the Apple phones. When I used it on this aging Razr phone, by the time I did get any results, I would have gotten it *much* faster by tapping the screen. On a new, *much* more powerful phone, Voice might actually work a lot better. But it is still nothing like Siri or any really good voice commander. What you can do with it is limited, the results are not always accurate, and it is very ...slow. I wanted it for hands free phone in the car and by the time I got what I wanted, if I got it, I was already at my destination.

So far as I can see, the Google Now Voice from any screen, hands free is gone. If you want it so bad, there are sites that show you how to enable it on Kit Kat and they give you the older version Google app to download and install. Plus some setup and configuring information. I found several of these sites. Putting in older versions of Google apps may not be a good idea, it will be overwritten at next update unless you prohibit it and you are now stuck with old Google.

Best bet is to get a new phone with lots of power. Ask in the CM12 thread for that phone if Google Voice is working so you will know beforehand. As to getting it working again on a Razr, I don't think it is worth the effort to downgrade your Google apps back to when Voice was enabled, and that is pretty much what you are going to have to do.

Don't mean to bust your bubble, but experience with Google Voice was NOT very impressive. I gave up on it long before Google discontinued it in the app. Although the features and commands you can do with it seem impressive, rarely ever did it work out the way you saw it on the Google Voice TV commercial. You "could" always get an iPhone with Siri built in. I do not much care for iPhones myself, but I do need a better phone. Saving money for the day I can to to Swappa and get a better one.

I like the Samsung Note 4, it is huge and it is, ...$700. The Samsung Galaxy S 4 (Verizon) is another good choice and is *much* more affordable at $120-300. 32 Gb sdcard ones go for $300. The Galaxy is also a phone you can root and rom. The specs are nice; 1½ times the CPU speed, double the RAM, and larger sdcard. For $120 or a little more, this is something I can afford at some point. I have unlimited data for life, so I have to buy my own phone and cannot take out a 2 year contract to buy one from Verizon or I lose the data plan. Besides, this way I can pick the phone I want.

Why am I telling you about other phones? Because, we are pretty much at "the end of the line" as to what a Razr phone can do. The apps and services are now eclipsing the hardware we own and it is only going to get worse. We Greenify and uninstall a lot of stuff just to keep the phone working well enough for daily use. Any further improvements in performance is not going to happen on a 3 year old Razr. This is just a "heads up". You can use the phone as long as you like.

Cheers! :)
