5. FAQ
Q: Why my smart phone detect usb device?
A: Smartphones make sure it supports the USB Host.
In addition, the Android version 3.1 (API Level 12) from the USB Host support.
Occasionally on the smartphone does not recognize USB devices (eg Galaxy Note 1). Smartphone otg cable to connect to leave only the part that is connected to the equipment by unplugging and re-connect if you recognize that this case is.

I try a lot of apps, but this one was the only one that really works fine for me, I'm very happy, I needed to work to check the GPS and AIS NMEA sentences, I don't need to carry my laptop with the f*****g Hyperterminal any more and works with many devices like the one from prolifics or Dlock thanks a lot to the Developers you did a really good work

No faffing about with windows inf files. Works fine on Sony Xperia Z talking to STM32F103VBT6 microcontroller USB ports running as virtual com ports (VCP) CDC (Communications device) firmware with any VID/PID. You MUST open the port by clicking the telephone-handset button near top right so that it changes to an X. Then you only have to remember to actually send your command typed in the lower pane by clicking the button that looks like an envelope (or a right pointing arrow). The app can optionally self start as soon at the USB is plugged in to your device - so be careful to avoid two instances running at the same time. If setting up memory buttons (function keys) then notice that CR LF are not needed in each button if they are ticked above the lower write pane. Full five stars. Excellent. Amazing.

happy to got utf-8 support. I would buy the pro, but I need inline typing (console mode, like e.g. minicom do) and support of ansi vt100 colors (escape sequences) to use it as a real uart console.

I tried everything I could but it did not work for me on a Galaxy S4 using a Startech USB to Serial (Prolific 2303). The app installs and runs fine and I can see the USB to serial device but as soon as I hit connect the app crashes and closes. Any ideas?

This is BY FAR the best interface for any serial terminal on the play store. It was exactly what I needed, but I had some issues. Twice I emailed the developer and he responded back with fixes THAT NIGHT. Now this is the perfect solution for me. Couldn't be more stoked about it.
