Customer Questions & Answers

does it detect wood studs?

Asked by: juan
Contrary to the answer that the Ryobi team gave, this device doesn't detect wood studs even if the only thing it was against was a wooden stud. This thing is useless. Get something that actually works the 1st time that you're in the store and save yourself the frustration of a 2nd trip.

Why dosent it work on other phones.I had a note 3 and it worked great. I now have a note 5 and it doesn't work.

I have the app. I plug it in and it says it's not plugged in. I put new batteries in it, Will not let phone detect the tool at all. I Also bought heat sensor and won't work either.
Asked by: FeelIwastedmymoney
Unlike previous Note phones, the Galaxy Note 5 has custom sound filter options (for music improvement) that may be interfering with Phone Works communication. The devices you mentioned plug into the headphone jack and communicates with your phone using audible tones... if those tones are being filtered then communication will not happen properly. Try going into your system setup and look for sound filtering options that may be activated (IE. UHQ Upscaler) and turn them off. That should help... if not, please call Ryobi customer service for further troubleshooting tips 877-578-6736 or write us at - thanks!

Customer Reviews

Phone Works Stud Sensor is rated 2.0 out of 5 by 101.
Rated 1 out of 5 by from I've found better designed tools in a Christmas cracker Please don't buy this useless piece of junk. After working unreliably at the beginning, now it doesn't work at all, even after going through the time wasting 'calibration' every time you need to use it. Online customer service is a bad joke, designed to get you to give up replying to their one a day, drip drip pointless questioning of my complaint. As an introduction to ryobi, I will never buy another product from them.

I like Ryobi products very much because they are very reliable and great quality. I am not sure if the item is working correctly or not. It kept giving me false readings and drilled some holes where there was not stud. I like the idea very much, but i had trouble connecting it to my phone. It is not compatible with my iphone 6s so I had to use and older Iphone 5 to be able to add it to the app. (same thing happened to the laser level). I think is better to invest on a more accurate device. This could be good for simple things, but not for a more regular use.

Tried it on two phones...LG G3 and iPhone. The LG couldn't detect it, even with the headphone volume all the way up. The iPhone thought it was the laser pointer. I then tried downloading the app to an Android tablet...not compatible. I have another old Android phone that I may dig out and try it with. If that works, I will consider editing this review. But until then, one star (prefer zero, but that's not an option).

Rated 2 out of 5 by from To complicated for the task The phone works product line is a new concept that I feel is not ready for prime time. Each product has to be registered to your smartphone and locked in with a serial number, that if your not careful you may accidentally discard as it is a flimsy piece of paper attached to the cord. You have to give Ryobi all your personal information to register the App, then activate the device. You MUST complete these steps before you can even begin to use the product. In my use of the stud sensor I found it performed poorly at finding studs in comparison to my traditional stud finder Home Depot sells (that doesn't require all the hassle!)
