Problem on My Fire HD 8

I am have a problem with sharptools on my Fire HD 8 with Fully Kiosk Browser. After 2 or 3 days the brightness on my Fire HD gets turned down to the lowest setting and sharptools is no longer on my dashboard screen it is on the account screen. I am not sure where to start troubleshooting. Has this happened to anyone else?

It sounds like Fully Kiosk Browser is crashing and recovering. Are you running any other apps on the tablet? And is the tablet running stock Fire OS or has it been modified to run Google Play / Google Play Services?

For the second part about SharpTools being on the account screen, be sure to set your Start URL to the full URL of your dashboard. That way when Fully Kiosk Browser recovers from a crash, it would load your desired dashboard by default. You can find the setting under Fully Settings > Web Content Settings > Start URL

And it should be something like:

I have not rooted the Fire HD if you are asking. I have the stock Fire OS apps and I have installed Google play / services following the instructions here:

I just had as the URL so I have changed it to the dashboard URL so that issue should be resolved.

Is there any way to determine why the Fire HD is crashing?

All the Fire tablets that I’ve installed Google Play on start to get tremendously sluggish after a couple days. Whereas tablets that were opened fresh from the package and had Fully installed (and no other tweaks) run nice and fast.

Is there a particular app or feature you were trying to use that requires Google Play Services? I would generally recommend trying to keep the Fire tablets as close to stock as possible as they are already somewhat performance limited (though a great bang for the buck!).

You can find a version of Fully Kiosk Browser that is optimized for Fire tablet devices directly in the download box of the Fully Kiosk website:


If you don’t need Google Play Services, you might start by removing that / reverting to factory defaults. If that doesn’t help, you might reach out to the Fully Kiosk Browser developer to see if he has any further tools for troubleshooting:

At the very least, it might be helpful for him to understand the issue with the dim level not recovering. Perhaps he could add a feature to recover the dim level properly.

I had experienced the significant sluggish when Google Play/services were loaded on my FireHD 10" as well. Factory reset and keeping it clean (nothing else installed except Fully Kiosk for Fire OS) is the way to go for me.

I used play to install fully. I don’t know why I did not install it from the developer site. I was also going to install tasker. It sounds like it will be best if I factory reset.

Thank you @josh and @James for you input.

I forgot to ask earlier. Are there any recommended settings you have for Fully to work efficiently?

I do not have any performance related settings applied in Fully.

The main settings I usually double check that I’ve set in Fully Kiosk Browser are:

  • Web Content Settings
    • Start URL: set to my full dashboard URL with ?kiosk=true appended
    • Enable Popups: on (optional)
    • Open URL Schemes in Other Apps: on (optional)
  • Web Auto Reload
    • All settings default at 0 / off - events are automatically pushed to your device and having the page auto refresh periodically can actually introduce more of a burden rather than help things
  • Advanced Web Settings
    • Enable JavaScript Interface: on (optional)
      • Adds a convenient ‘Set Start URL’ option within the … menu of the dashboard list
    • Keep Screen On while in Fullscreen Mode: off (optional)
      • If you are running a newer version of Fully Kiosk Browser, SharpTools will prompt you about this setting when you first try to use the fullscreen icon in a dashboard
    • Fake User Agent String (optional)
      • You can use this to emulate an iPad or other device to enable Google Login within Fully Kiosk Browser. Our recommendation is to use a linked email/password or phone login though.
  • Screensaver (optional)
    • I usually set mine to go to a dark screen after a minute or two.
      • Some people like to build a specific dashboard to use as their screensaver with just a clean image as a background and maybe a calendar/news/weather.
    • Screensaver Timer: 60 (or whatever value you want)
    • Screensaver Wallpaper URL: fully://color#000000cc
    • Screensaver Brightness: 1
  • Device Management
    • Keep Screen On: on
    • Screen Brightness
      • I just noticed this setting - I wonder if it would help with the dimming issue you experienced. Maybe give it a try?
    • Launch on Boot: on
  • Motion Detection (optional)
    • These settings pair up well with the screensaver so that your tablet will automatically wake when you walk in front of it. Though it should be noted that the camera will have a hard time seeing you in the dark, so you could use a motion sensor with your hub to wake the device if you prefer.
    • Enable Visual Motion Detection: on
    • Exit Screensaver on Motion: on
  • Remote Administration
    • Enable Remote Administration: on (optional)
      • If you want to be able to control Fully Kiosk Browser from your smart hub, there are device handlers for SmartThings and for Hubitat.

Make sure to not use the screen off features on a Fire Tablet unless you don’t mind having to manually unlock the screen (eg. do not use the ‘Motion: Turn Screen Off in Darkness’ or ‘Device Management: Screen Off Timer’ or ‘Power: Sleep / Force Screen Off’ type features). Most people use the Keep Screen On setting along with a black/dim screen as the screensaver to workaround this on Fire Tablets.

@josh thank you. This will be very helpful.

By the way, somehow I haven’t seen much talk of this in the home automation boards, but the fire 7 (5th and 7th gen) and 8 tablets are 100% unlockable/rootable now. I just finished installing a custom Android ROM on both of my 2017 fire 7s, and it’s perfection. No more black screensaver for me. They turn off in darkness and wake on motion, no lock screen.

Only catch is, you have to have access to a Linux computer (raspberry pi will do great) and you have to pry the back off the tablet to short a pin on the mb during part of the process. Lol it sounds worse than it is, really. :joy: My second one literally took 5 minutes, most of which was just watching the 2 scripts run.
I now have TWRP and can load any ROM I choose just by holding volume down+power and installing from sd. Wouldn’t hesitate one minute if people are interested in getting the best auto-off-on experience possible.

In my case, the black screensaver was a no-go for the bedroom. Even that amount of light was too much, and not being able to trigger it with darkness meant having to wait until the timer set the screensaver… Not good enough for me. I decided to check again in the hopes that someone had figured out a hack, and lo and behold! They have indeed!
