If you're using a newer device with Android Nougat, select "Virtual keyboards" instead, then tap the "Manage keyboards" button at the bottom of the screen. When you're done there, back out one level, then tap "Current keyboard" again, and choose EVA Keyboard from the list. If your phone does not have the "Current keyboard" option, simply tap any text input field. From here, a keyboard icon will appear in your status bar or navigation bar.

If it appears in your status bar, open your notification tray and tap the corresponding notification.

Otherwise, just tap the keyboard icon in your navigation bar. Finally, choose EVA Keyboard from the list, then you'll be done with this step. If you got booted out to a different screen while setting up the keyboard, you can do this by opening your recent apps menu, then selecting the EVA Wizard entry and tapping your back button two or three times. The following are two of my favorite apps.

The first is called NetCounter, and it simply displays a tally of the data transfer that took place over either your cellular line or your Wi-Fi connection. Another cool app to tap into the status of your Wi-Fi signal is aptly called SpeedTest. Once the test completes, the dial rests on your current upload speed in kbps, and the application reports both your upload and download speeds resulting from the speed test.

In addition to the data transfer speed of your current network, you might also want to know the general signal strength of the local Wi-Fi network. The Wifi Analyzer app provides a cool graphical display of the current strength of your Wi-Fi connection. The signal strength shown here was the strength of my home Wi-Fi network in dBm sitting across the house from my wireless router. As I walked across the house closer to where the router is located, the needle gradually worked its way up the scale. I was pretty impressed with how accurate the application appeared to be — every little movement I made either closer or further from the router resulted in a bounce of the display needle.

This application basically senses every little shake or wobble of the phone, and plots it out on a graph. I produced the chart below by holding the phone steady, and then very gently bouncing the phone in intervals. The sensor was very sensitive, and caught every movement I made with the phone.

I can think of a number of uses for this application that would really come in handy. The motion gets logged and you can save the chart to a log file on your SD card. This is definitely one of my favorite apps for the Android. At the very least, you can turn it on when you feel an earthquake coming on, and record the size of the quake! These examples are only a few of the many cool Android apps out there that tap into your Android phone system sensors and report back with data.

You can exploit the high performances of SS04U to capture all the flicker phenomena and make use of the formal risk assessment developed by IEEE SS04U paired with LxMeter app can outperform most of the best flicker meters on the market by measuring:. This sensor will measure the color temperature and chromaticity of both ambient and flash lights, helping you to get the right white balance in your photos.

By using this option, SS04U actually becomes a colorimeter and it provides a valuable support in the calibration of output devices such as color monitors and printers.

It can take both illuminance and color measurements while offering Bluetooth Low Energy cordless freedom. Download SS04B datasheet:. SS04 sensors are supported by the Android app LxMeter. Unlike light sensors embedded in smartphones, the SS04 sensor has been designed specifically for measurement purposes and has the following unique features: - Hemispherical receptor for a degrees detection - Spectral sensitivity matched to that of the human eye - High dynamics and high accuracy of the measurement - Flash measurements - Sensor pre-calibrated by the manufacturer - Features do not vary among smartphone devices.

While you may be tempted to go on a photo shoot without one, a handheld light meter is still essential to obtain optimal results in your photography.


In-camera metering operates as reflected metering and would indicate different exposures for each object. When the scene has large areas of very light or very dark values, such as in these cases, the reflected meter is thrown off. With light sensors as SS04 you can take incident readings and obtain perfect exposures. During flash mode the SS04 sensor keeps track of the light levels and holds the peak value. SS04 can capture very short light impulses, a feature commonly found only in expensive light meters. A list of Bluetooth receivers compatible with LxMeter will be published as soon as they will be fully tested.
