You've (accidentally) turned on "high contrast text" accessibility option, an experimental feature on Lollipop. From Google official support,
High contrast text
This information applies only to devices running Android 5.0 and higher.
High contrast makes text easier to read on your device. This feature fixes the text color as either black or ...
Accessibility is a category of features which are usually used to assist people who are in some way disabled. For example people who cannot see well can turn on Magnification Gesture to triple tap the screen and it will zoom in on whatever screen you are on. Also it can reverse the dark and light colors to help them see and read text better. Also, there are ...
Since Android 5.0 Lollipop, the feature is built-in as one of accessibility options.
Below Display section, toggle Color inversion.
After toggling it for the first time, the "Invert colors" toggle will be added to the quick settings menu.
You haven't mentioned you Vizio Table version, but assuming that it is Vizio 8 (VTAB1008), I've contacted their support team, through the Live Chat:
Evan: Thank you for contacting VIZIO Live Chat, the home of Entertainment Freedom for All. This is Evan in South Dakota. Have you ever contacted us before?
Salustiano Silva: Nope!
Some keyboards like Swiftkey have the option to place arrow keys on the keyboard, which will then allow for scrolling on web pages and such. They also have a free one month trial if you want to try it before you spend money :)
Try going into Settings / My Device / Accessibility and turning on Magnification Gestures.
A triple tap on your scree will enlarge what is there including text and then another triple tap will take you back. While it is enlarged, you can scroll with one finger.
That's the best I've found so far.
I have a Targus bluetooth keypad that I can connect to my Tablet/Phone and use it as a number pad. It has a Num Lock switch so it can also be used to input up/down/right/left and PageUp/PageDown.
It however depends on your device if your onscreen keyboard vanishes when you connect to a bluetooth device or not (my ICS CyanogenMod9 does hide the onscreen ...
I've never seen this option built-in, but there are several apps/widgets on the Playstore offering a "quick boot" as well. The term is a little misleading, as it's usually not a boot at all.
For some background information, let me first refer to my answer on Can somebody explain the boot process of an Android device?. Quick-reboot usually kills everything ...
You can't change the text size in Google Maps, because the whole map, including the labels, is retrieved from Google's servers as an image. (In fact, they're lots of small images called tiles. For this reason, using a different app that embeds Google Maps won't help at all: they're all just displaying the same tiles.
If you want a map that looks different, ...
T-coil is a function of the phone hardware. It requires the speaker to be rigged in a specific manner to allow it to inductively couple with the coil in the hearing aid, though there exist telecoil adapters such as the Music Link for devices without such support.
You can often find listings of what devices offer what kind and level of support for hearing ...
A bit late I know, but I've just been having a similar problem with a Samsung Galaxy S3 Mini.
This is how I got rid of it. I tried other ways, but found that if I turned the phone on and off again, the speech would come alive again. This was the only way I could kill it off for good.
Go to Settings -> Accessibility -> Text to Speech and there will be ...
If you're using Samsung Galaxy S-series, you can change the call answering and ending options in Settings > Accessibility > More settings > Answering and Ending calls. I didn't like the way it worked, I now have it set up so all I press is the home key.
The other one is Single tap mode, which is like its name, answering/rejecting incoming calls with a ...
Requires root access.
I won't go into the details, but know that it doesn't replace your home launcher but gives you PIE navigation among other things, which comes down to this:
(Click image to enlarge)
You can set a PIE to Menu/Overview action from LMT app → PIE → select a PIE item → Menu
Make sure you activate the LMT ...
From source code of Launcher3 in Android 6.0.1 r16:
The workspace is a wide area with a wallpaper and a finite number of pages. Each page contains a number of icons, folders or widgets the user can interact with.
Honestly, this is the first time I heard the term workspace in context of a launcher for Android, but if you want a standard term, there you ...
I was facing the same issue on my Lenovo vibe k5. I did the followings to solve the issue.
Enable accessibility for the concerned app in the Settings.
In power saving option (in most cases it is inside the "Battery" option) select the concerned app not to be optimized.
Select the app as device administrator (this setting may be found inside "Security" ...
So from what I can determine:
Google announced native support for hearing aids with a specification called ASHA
Based on this article on XDA Developers, it appears that only Pixel devices are enabled in AOSP, but that doesn't mean that manufacturers can't enable it for their own devices.
Looking at the ASHA specification it looks like a new service on top ...
You can make text larger by going to the Settings app and clicking on Display and then Font size. Unfortunately, not all developers test their apps with different font size settings, so you may find some apps look bad or have their buttons in the wrong place. If you find an app like this you should always complain to the developer.
Newer Android devices ...
After more searching, I found SubtitlePlayer in the Google Play Store.
It seems to work adequately for what I need, but because its name is two words jammed together, doesn't show up when you search for "Subtitle" in the market.
Also, the page says it needs 'Unicode' subtitles; after a few tries, I got it to work correctly with UTF-8 encoding, without a ...
I got the solution!
Somehow I could get into the settings menu by turning aeroplane mode on and starting Google Maps (which is on my home screen). Google Maps then sends you to settings. In there I can scroll using three fingers.
The app has multiple input modes. In the default, tapping the display moves and clicks the mouse. In another mode, the display acts like a trackpad, so dragging along the screen causes the mouse to move accordingly on the remote system. See the "input modes" sections of the documentation for details. You can change the input mode from the app menu without ...
It's not a built-in feature on Nexus devices, but Samsung devices have this in the accessibility settings.
Inverting all colours isn't much use, as some apps have
light text on a dark background, and some apps have dark text on a light background. Making text easier to read is better achieved by increasing the text size, which is an option on all Android ...
Settings --> Display --> Font size will adjust the font from "tiny" right through "huge" on the system pages (like Settings) on the two Samsung devices I have. Tinkering with brightness and mode can also help boost contrast. If you head over to Settings -- > Accessibility --> Vision, there are additional/duplicate adjustments for magnification gestures, ...
I also suffer from this problem hence the reason for trying to find a solution. I have just compared the results of Google maps with an app I downloaded a while ago and keep forgetting about. The result is not massively bigger road names / numbers but much easier to read. Bonus is that the maps are used offline, just need a gps signal to show directions ...
Make sure that you select the same language under the following options:
1. Settings -> Accessibility -> Text-to-speech output -> ***** Text-to-speech,
settings button behind it -> Language -> English(United States)
2. Language and Input -> Language -> English(United States)
You may select any Language, but choose the same language in both of ...
Talkback is open source, and the files available on Github:
The audio files are included in the repository in .ogg format. Simply download the repository and extract all of the .ogg files to access the audio.
In theory when a blind user first starts up the phone they have the option to start talk back. When it is turned on at start up, the tutorial automatically starts.
This option is available for devices running Android 4.0 and above.
When you first turn on your Android device, you can enable TalkBack from the initial setup screen.
You should think of "Talkback" as its own app, like any other app in Android. So the version of the Talkback-app usually has not much to do with the Android version. You can have a new version of Android, but an old version of Talkback and vice versa.
Most of the time the Talkback-version in a newer Android is also newer, but you could manually upgrade ...
Since the bounty expired (went unawarded) and this question hasn't received an answer yet, I just decided to explain the short term workaround as it may help users facing a similar problem.
Why I needed this feature:
In order to use my productivity apps such as AutoInput, Greenify etc
To be able to monitor which applications whose accessibility settings ...
