Comes with the following preinstalled apps:
Try to disable the continuous scanning for new WiFi networks. You can find this option through the settings menu.
There is a very handy and free tool available in the Play Store, called Wi-Fi Analyzer.
This app will show you all nearby Wi-Fi networks (e.g. the ones from your neighbours) with additional information, and also suggests you, judging on all the other Wi-Fi networks on air, what channel is best to use for you.
Once you have set that 'best to use channel' in your router, go ahead and check if you experience an improved Wi-Fi stability.
Always check what Wi-Fi transmitting channel your router is using.
Most often the default channel as set by manufacturers is "auto" (automatic), this usually being something in between channel 6 and channel 9.
When you are in an area with more Wi-Fi networks (read: pretty much all scenarios), it's possible that the Wi-Fi transmitting channel is conflicting with the others, causing signal interference/corruption.
In your router's configuration panel (please refer to the user manual of your router for information to access that configuration panel) you can set your Wi-Fi channel.
The Android OS has an application called "suspendproces" which is always running in the background and in some cases can use the CPU up to 50% -60%.
The problem is that it also happens in standby mode, resulting in a continuous drain from the battery.
Set the "Screen Timeout" in the "View" menu setting to "Never turn off". It sets suspensproces off and stays off.
As a result, the screen and the backlight do not turn off automatically by inactivity, but you can simply explain to the end-user that almost everyone, after using the tablet the ON / OFF button must be pressed to enter the standby mode.
FYI: There are several Android devices where this problem occurs involuntarily, including smartphones such as HTC. It shows a combination of software and hardware, and also appears in the recent Android version 3.x
Extra battery saving tips:
Do not set the screen brightness to the maximum.
Turn off automatic Wi-Fi scan. The tablet is by default constantly searching for new wireless networks: Settings - Wireless & networking - Wi-Fi settings - uncheck Network notification.
First use the tablet with the load that is currently present in the battery. Only when the battery is empty, then perform a first time full charge. This is the better for the battery life and performance. The optimal capacity of the battery reach you after a few cycles of full discharge and recharge.
Your Yarvik TAB09-211 Xenta 97ic+ runs the Ultra HD resolution of 2048 x 1536 pixels by default, for an unprecedented viewing experience.
However, if you’re experiencing performance issues with this resolution, like lagging or ‘stuttering’ during display build-up (e.g. in certain apps, games, or system menu’s), you can manually lower the display resolution of the tablet to the still superb resolution of 1600 x 1200 pixels.
1. Enter the tablet’s settings menu by pressing the ‘Settings’ icon in the app screen:
2. In the settings menu, click on ‘Display’ in the settings list on the left, followed by ‘Display mode’ on the right part of the screen:
3. You will now be asked to select the ‘Display mode’ (display resolution), with ‘Normal’ being 1600 x 1200 pixels, and ‘HD’ the default 2048 x 1536 pixels.
Click on ‘Normal’:
4.The tablet now needs to reboot in order to apply the resolution change.
Click ‘Ok’ to let the tablet reboot:
5.After the reboot, the display resolution of your Yarvik TAB09-211 Xenta 97ic+ will be set to 1600 x 1200 pixels.
You can repeat the above steps at any given time to select ‘HD’ again, to bring back the 2048 x 1536 resolution.
The standard resolution is 2048x1536, but this ultra HD setting can potentially cause some lag in browsing and refreshing pages.
To set the resolution to a lighter 1600x1200 (still HD) you can follow the instructions in the video below:
