Recommended Devices

Most modern Android tablets or Amazon Fire Tablets that ship with Android OS 5.0 or Fire OS 5 (respectively) are compatible with TouchDRO, as long as they satisfy the above system requirements.

The following tablets are commonly used and have good track record:

There are hundreds of other Android devices currently on the market, covering a range of features, sizes and price points.
TouchDRO's user interface is designed primarily for tablets.
The application will work on smaller devices, such as phones, but the user experience will be less optimal.

1. TouchDRO can be installed on a non-tablet device (a netbook or even Raspberry Pi) running Android 5.0 or later and used with keyboard and mouse.

2. Even though the application supports USB connectivity for some USB controllers, such as FTDI RS232, BlueTooth is recommended as the connection is more stable and reliable.

Problematic Devices

In October of 2022, Samsung has introduced a bug in their latest release of Android 12 that affects TouchDRO. The symptom is random momentrary freezing for the position readout for about 150-750 milliseconds which happens every few seconds. This affects all Samsung tablets running Android 12 and Android 13.

There is currently no fix or workaround for ths issue, since this is an operating system/driver bug. At this time it's recommended to avoid Samsung tablets running Android 12+ and block OS updates on tablets running older versoin of Android.
