Comments on TelStop for Android

★★★★★ Works like it should It just works. Test it with the link on the description page and make it the default dialer. You won't see it again unless you stumble onto a malicious link.

★★★★★ Simple solution for a difficult problem Trigger the request for default handler in app. Open a browser window to a test page for the user? (Couldn't read white text on transparent background.) Test page not cell phone friendly. I had to zoom in (Firefox). I like it. CM7.1 HTCDHD

★★★★★ Great work, thanks! Nice, small fix for a potentially serious problem (read about it in Android Magazine).

★★★★★ Doesn't work Does not work on my razr. I get the same warning dialogue pop ups when I click on either test page. It also comes up when I click on links that I know are safe such as my office website.

★★☆☆☆ J K C DROID RAZR MAXX Set as default app; unable to make outgoing calls; wonder if app will protect even though not default. If so, will change rating to 5-Star!

★★☆☆☆ Vodafone Hw every ussd code for vodafone is malacious. Surprised.

★★☆☆☆ CASIO G,Zone C771 Bugging Says it is compatible with my phone. Want let me make calls (dialer just comes up over and over). Want do anything when set to default. I uninstalled rebooted, installed, rebooted and follow instructions and didn't work then. Frustrated. I was so excited to have this and it doesn't work. UGhhh! Would love to know a fix! I understand that all Apps have some sort of bugs. In this case a HELP section may be note worthy! I wanted to give this 5 stars, but sadly it is getting 1 for the CASIO G-Zone.

Description by Collin Mulliner Written by the developer, not by AppBrain. Click to read.

This is a quick fix for the TEL attacks described here [2].

TelStop publishes a TEL handler and will be invoked on every phone call the originates from a TEL URL. TelStop will only show itself if it sees a problem with the URL. You will only see the WARNING screen if the URL looks fishy.

After installing try the TelStop Test Page [1]

Recent changes:
Now supports HTC devices in transparent mode.

Other devices (Moto, Samsung, ...) will follow.

Please report problems.

Fully transparent mode, will only bug you if it detects a malicious TEL URL.
