Downloaded app ______ cannot be installed, it appears to be incompatible.
While our Android tablets support most of the available apps from the Play Store, Chinavasion cannot test and guarantee the compatibility with all various apps.
Some apps may be unavailable in a region, also some apps requires a special software or hardware feature. In these cases, using an alternative app store or downloading the necessary app from the Internet may help.
How to connect the Android device to a PC?
1. Connect the device to a PC using the supplied USB cable.
2. The tablet screen will show a “USB connected” notification. You may have to open or pull down the notification bar.
3. Select the USB notification. A new screen should appear with a button “Turn on USB storage” Touch this button. Now the computer should recognize the Android tablet’s storage as a mass storage device (removable USB drive).
Additional drivers are not required for file transfer.
The computer may search for ADB drivers. This option is available only for developers. We cannot provide ADB drivers.
On some, mostly older Android devices “USB debugging” option needs to be enabled. It can be found either in Settings > Developer options, or Settings > Applications > Development menu.
How to restore factory settings?
If you just want to revert the device back to default factory settings, then you need to perform factory data reset.
To perform a factory data reset go to Settings > Backup & reset menu. On some Android systems you may find it either in Settings > Privacy, or Settings > Storage, or directly in Settings menu.
Please note that user data will be deleted.
How can I sign out or remove Google account?
Go to Settings > Accounts > Google account. Choose the account, press menu button and select “remove account” option. However, in most cases it will not work, if service and apps already uses the account. The only option is to perform factory data reset. It restores all the default factory settings. User data will be also deleted.
Factory data reset can be found under Settings > Backup & reset menu. On some Android systems you may find it either in Settings > Privacy, or Settings > Storage, or directly in Settings menu.
The touchscreen does not respond correctly
For capacitive screens: Capacitive touchscreens are highly sensitive to charging voltage and current. Incorrect charger or battery may cause touchscreens to malfunction.
1. Please check if it happens regardless the charger is connected or disconnected? In case the issue is caused by battery or charger, please contact support@chinavasion.com with related order number, item code and details of the issues so that we can help.
2. If it happens when NOT on the charger, then perhaps you want to make sure, that you’re not holding the device in such a way that the heel of your hand is touching the display on the sly.
3. If you can still access the menu, have a try to perform factory data reset.
Factory data reset can be found under Settings > Backup & reset menu. On some Android systems you may find it either in Settings > Privacy, or Settings > Storage, or directly in Settings menu.
Please note, that user data will be deleted.
For resistive screens:
The response of resistive touchscreens is different from capacitive touchscreens, as it is sensitive to pressure on a small surface unlike the capacitive screens.
1. Please use stylus or your fingernails for more precise navigation on the touchscreen.
2. Please recalibrate the touchscreen. Different phone models use different way for calibration. Look for “calibrator” or “touch screen” app on the app drawer menu; or check Settings or Settings >Display menu for calibration option.
How to set up 3G and MMS?
Most mobile network service providers send 3G configuration message automatically. However some OEM or less well known brands are not recognized by the provider so the configuration needs to be done manually buy the user.
1. Go to APN settings under Settings > Wireless and networks > More > Mobile networks > Access point names.
2. Press menu button select "New APN" then enter the parameters according to your provider's settings.
3. When done, press menu button, select "Save". Select the created APN.
4. Go back to Settings > SIM management menu and chose correct SIM card for data traffic and enable data connection.
As the wholesaler, Chinavasion does not provide customer support for 3G/GPRS/MMS configuration. Instructions are available from your cellular service provider’s website and service centers.
Alternatively you can use an app to configure 3G like the app called Tweakker. https://play.google.com/store/apps/details?id=com.tweakker&hl=en
This app supports most service providers, however we cannot confirm the perfect operation with all networks and all cellphones. You can also find other 3G settings app in Google Play Store.
Why is the internal memory capacity less than the specified?
We often get emails from our customers asking why the internal storage available for use on Chinavasion smart phone or tablet is less than what’s stated on the specification sheet.
Please note that the internal memory on Android devices with 4.0+Asystem version is split to multiple partitions. Please check the total storage capacity.
Please note that the ROM capacity is not equal with the internal storage available for the user. Some part of the ROM is allocated and reserved by the system and preinstalled apps.
Please check the following article about the internal and RAM memory capacity and how is it calculated:
http://blog.chinavasion.com/index.php/11045/where-has-my-internal-storage-gone/
It’s not a unique issue with smartphones and tablets. Even flagship models, like the Samsung Galaxy S4 allows for only 9.15GB of actual accessible memory out of 16GB internal memory.
