Cannot Blinkup on Android?
Since every Android device has a different refresh rate, luminance decay rate, etc... some devices drop frame irregularities, which can result in Blink-Up failure. This occurs because Android vendors vary on how important they consider consistent frame rate to be, therefore each Android device and/or make/model will behave differently during Blink-Up. We anticipate improvements are going to be in the Android software stack, which prioritizes frame rate just as iOS devices.
Please try the steps provided below to complete the Blink Up process.
- Close all open apps.
- Disable mobile data. If in doubt, put the phone into Airplane mode and enable WiFi.
- Have the brightness turned all the way up on your device ( auto brightness off ).
- Disable battery saving/low power mode.
- Have your screen completely flush against the controller with the screen facing down toward the photo sensor.
- Perform Blinkup in a dark place where there is no ambient light that could interfere with this process? Feel free to take the front panel into your house as this can help remove ambient light.
- When you are going through the blink up process (your phone is turned and pressed against the Rachio's photosensor), the WiFi light should stop flashing during blinkup. If it doesn't stop blinking, the controller didn't see the blinkup code from the phone.
- When the light first starts flashing again, what color does it flash? The WiFi light should begin flashing green. If is it any other color reference our WiFi Light Color Codes to see what may be occurring.
- Drag the status bar downwards, then tap
- Find and tap Power management.
- Drag the slider beside STAMINA mode to the right, then tap Activate.
Other Quick Tips:
1: Samsung devices have had several screen setting changes over the past few years. If you have a Samsung Galaxy S6 or a Galaxy Tab S (or later models) try using the Amoled Cinema screen setting. If you have an older Samsung device, try using the Basic Mode screen setting. Also toggle off Daydream if applicable as this can interfere in the Blinkup process.
2: Some users have reported that holding the Android phone roughly a half an inch above the photo sensor in a dark room allowed them to successfully connect.
