Cause 2

5 2 Screen and Display A small gap between the front and rear housing is required to allow space for the housing to expand and contract when subjected to changes in temperature. This is normal and does not indicate that your tablet is faulty. All Huawei tablets are manufactured according to stringent quality control standards and are safe to use. Solutions Insert four sheets of A4 paper into the gap. If the paper fits into the gap, contact your nearest Huawei service for assistance. If you suspect that your tablet may be damaged, contact your nearest Huawei service center for assistance. Note The industry standard for the gap between the front and rear housing is 0.4 mm. Huawei tablets are designed to have a gap of less than 0.35 mm. 2.2 Why does the rear housing bend when I apply pressure? Cause For safety reasons, there is small gap between the battery and the rear housing. This is normal and does not indicate that your tablet is faulty. Solutions If the rear housing becomes loose, contact your nearest Huawei service center for assistance. 2.3 Why do my power button/volume buttons appear uneven or tilted? Cause As volume and power keys are frequently used, they cannot be guaranteed to remain completely level. Repeatedly pressing the keys on one side, rather than in the center, can result in the volume or power keys becoming uneven over time. This should not affect the function of your tablet. Suggestion If the keys are no longer functional, contact the nearest Huawei service center for assistance. 2.4 What is the rear camera lens coating made of? The lens on the rear camera is covered by a layer of acrylic glass. The glass is shatter resistant, but not shatterproof. Thus, take care not to damage the lens. Solutions 3

6 2 Screen and Display Use a protective case to protect your tablet against bumps and scratches. Do not allow your tablet to come into contact with sharp objects (such as keys), as these may damage the lens coating. In the event of any accidental damage, contact your nearest Huawei service center to purchase a replacement lens cover. 2.5 How can I prevent the paint on my tablet from getting scratched? Cause Online answer Scratched surfaces or damaged paint on the rear cover or card tray of the tablet can result from: Connecting or disconnecting external accessories, such as headsets or USB charging cables. Contact with physical objects such as desks or tables. Repeated removal and insertion of the SIM card tray. Damage to the outside cover or paint occurs normally over time. Hotline answer For new tablets: If the tablet is brand new out-of-the-box and there is damage to the external cover or paint, please contact the seller. For used tablets: While Huawei has high standards for the durability and quality of paint and external surfaces, damage may still occur as a result of: Small stress effects, such as: Contact with desks and tables, or objects in pockets or bags, such as wallets or purses. Connecting or disconnecting external accessories, such as headsets or USB charging cables. Repeated removal and insertion of the SIM card tray. Accidental contact between the tablet's side buttons and button holes. Large stress effects such as: Contact with hard objects such as keys, the ground, or the edges of tables and desks. Falling and striking against hard surfaces. Severe bending due to external force. Damage to the outside cover or paint of a tablet occurs normally over time, and may be more evident for models with glossy or deep-colored paint. Suggestions We suggest using a protective case that matches your Huawei tablet. 4

7 2 Screen and Display 2.6 Why is the camera off-center? Huawei tablet cameras are assembled with strict control standards (less than 0.35 mm, while the industrial average is 0.4 mm). The camera functions are not affected even if the camera looks off-center. Please rest assured. If the camera functions are affected, back up important data and take your tablet with the receipt to an authorized Huawei service center for repair. 2.7 Why is the SIM card slot loose? A small gap between the SIM card slot and your tablet's housing is normal. However, if the SIM card slot is loose and doesn't stay in place, contact your nearest Huawei service center for assistance. Note for hotline staff: All Huawei tablets are tested to ensure that the gap is no more than 0.25 mm. This is smaller than the industry standard of 0.3 mm. 2.8 Is the glass on the rear camera lens shatterproof? The glass is shatter resistant, but not shatterproof. Thus, take care not to damage the lens. Solutions Use a protective case to protect your tablet against bumps and scratches. Do not allow your tablet to come into contact with sharp objects (such as keys), as these may damage the lens coating. In the event of any accidental damage, contact your nearest Huawei service center to purchase a replacement lens cover. 2.9 Can I use earphones with a USB Type-C connector? No. Your tablet only supports earphones with a 3.5 mm jack Why does the volume down button respond when I press the volume up button? Cause You pressed too hard on the volume up button, or you pressed in the middle of the volume up and volume down buttons. Solution 5

8 2 Screen and Display Avoid pressing too hard on the volume up or down buttons, and avoid touching the middle of the button. If the issue persists, contact your nearest Huawei service center for assistance Why are there bezels around the edges of the screen? Standard response This is a design feature. The bezels have been designed to give the tablet a seamless look when the screen is turned off. Do not respond to complaints posted on forums or other websites. Response for online retailers Thank you for your feedback. We appreciate your comments and will refer them to our product design team What can I do if my screen is darker than screens on other tablets, even when the brightness is set to maximum? If the screen brightness is set to maximum and you cannot see the screen clearly, contact your nearest Huawei service center for assistance Why does the screen look uneven? The ambient light sensor and LED indicator feature a special coating that may produce different visual effects when viewed from certain angles. This is normal and does not indicate that the screen is faulty. The screen features a special coating and may appear slightly uneven when viewed from certain angles or under certain lighting conditions. This is normal and does not indicate that the screen is faulty Why are there horizontal lines across the screen? Cause These horizontal lines are produced by your tablet's digitizer, which is part of the touchscreen. It is possible to generate a static charge when you clean the screen, remove the screen protector, or swipe the screen quickly, which causes horizontal lines to appear on the screen. This is normal and does not indicate that your tablet is faulty. Solutions Switch the screen off before cleaning it or removing the screen protector. For best results, use an official Huawei screen protector designed for your tablet. 6

9 2 Screen and Display 2.15 Why does the status indicator not display the color I set in an app (such as WhatsApp)? Problem: The status indicator for message notifications does not appear in the color you set in a certain app such as WhatsApp. Cause: Owing to differences in the way that mobile tablet screens transmit light, the colors may be displayed a little bit differently. This does not indicate a quality issue with your tablet There will be water ripples when I press the screen There will be water ripples when you press the screen, screen edge is more obvious. All LCD screens will have water ripples, this is because the liquid crystal distribution has changed when you press the screen. HUAWEI tablet using the best design, water ripple is very small, this does not affect the use of tablet. Advise:Suggest that you use the normal strength, water ripples will not appear, and will not affect your reading and playing games. 7

10 3 System and Settings 3 System and Settings About This Chapter 3.1 After restarting my tablet, why does it display the default Google input method on the unlock screen? 3.1 After restarting my tablet, why does it display the default Google input method on the unlock screen? Problem If the user has configured a third-party input method but secure input is disabled, the lock screen will display the default Google input method after a restart.

16 7 Backup, Restore and Update 7.3 Why can't I connect my tablet to another device using an OTG cable? Solutions Check whether the devices have a micro USB or a USB Type-C port. If both devices feature a micro USB port and you are using a micro USB to micro USB cable, check that the cable is inserted correctly. The connector labeled 'host' should be inserted into the host device (the host device is the device that provides a charging current). If you are using an OTG cable, insert the micro USB connector into the host device. If the host device does not provide a charging current, this indicates that it does not support OTG. If your tablet has a USB Type-C port, purchase a Huawei USB Type-C to micro USB adapter, and then connect the adapter to the micro USB connector on the cable. When you use an OTG cable to connect your tablet to a USB storage device, your tablet will provide power to the device. Some USB storage devices that have a high power rating (such as portable hard drives or tablets) may not function properly. Insert the cable into another device.

Your tablet's temperature may vary depending on the apps you use, the ambient temperature, and other factors. At room temperature, your tablet's temperature should not exceed 45 C. However, it may exceed this temperature if you use the camera, make video calls, or play resource-intensive games for prolonged periods. Using your tablet while it is charging also increases the chance of overheating. Your tablet has a built-in safety feature which automatically switches off your tablet when it gets too hot. All Huawei have passed stringent safety tests and are safe to use. 24
