Huawei P9 and Leica probably did the one of the most advanced mobile phone cameras yet. It’s boasting a dual camera that will take a newbie to master how to use somehow. Here’s some tricks and tips.
1. Adding Watermark
One of the unique features to the Huawei P9 is putting a watermark on your shots. A weird feature that was different from other camera softwares. Yes, the P9 camera allows you to add watermark to your images. You can watermark image with different annotations, time, location, food, weather, sports and moods. You can even put the Shot on P9 watermark with the P9 logo on the corner of the image.
2. Using Shortcuts
When you opened the default camera app, you can do the following quick gestures to access various parts of the app:
Swipe left to switch to modes
Swipe right to enter settings
3. Burst shooting
You can capture more than one image one after other, simply when you touch and hold the camera shutter button. It will take continuous shots and on P9, the pictures came out to be very impressive.
4. Assign a function to the volume key
You can assign a function to the volume key to make using the camera app easier. Just
Open camera
Go to settings
Volume button function
It will let you choose from 3 different options:
Shutter– Use it as a shutter button to capture pictures.
Zoom– You can use it to zoom in and out while clicking a picture or shooting a video.
Focus– You can change and shift focus using the volume key if you select this option.
5. Using Nightshots
Huawei P9 comes with a dedicated mode for night pictures like many other phones but there is something unusual in this one. It offers manual ISO and exposure control in the Night Shot mode. This helps you to get rid of the unwanted noise and grain in the night pictures.
Your Huawei P9 have a huge battery but also a hungry chip that needs more power to sustain its blistering processing speed. Here’s how you can extend your battery life with these 5 easy tips.
1. Use static wallpaper
Vivid, live wallpapers look very good on your screen. However, the animations which they use, tend to use up way more battery that a normal, static wallpaper.
Go to Settings > Display and Wallpaper
2. Turn off Auto-Upload with Google Photos
If you use the Google Photos app, you will surely be asked to do backups. If you agree, the application will perform those backups while connected to the WIFI Internet. However, it you do not care about your photos being uploaded to the Internet right away (after getting the WIFI connection), you may just turn it into “While charge only” which will definitely relive your battery.
Go to Google Photos > Settings > Auto Backup
3. Use “Power saving” instead of “High Accuracy” in Location
In order to identify the exact location of the device, you can use three sources: GPS, WIFI and your mobile network, However, using the mode “High Accuracy” uses up a lot of energy. When you do not need the very precise locations, you can turn off the GPS signal and use only WIFI or mobile network (“Power Saving” mode) – it will surely decrease the usage of your battery.
Go to Settings > General > Location > Mode
4. Automatic power saving mode
Even when you do not use your device, it still does some work (synchro, updates etc). Each of those uses up your battery. Thankfully, Android offers the Power Saving mode, which makes your device use less energy that normally (less frequent email checking, synchro etc). You can turn this mode on anytime you wish. What is more, you can also set the automatic turning on this mode when the battery reaches a certain level (usually below 5% or 15%).
Go to Settings > Battery > Power saving mode
5. Adjust brightness
Nowadays the mobile devices are equipped with bigger and bigger screens (even the Apple device are following that trend). However, the screen is the biggest energy devourer so if you wish to save your battery, you should start with that. First of all, check the settings of brightness – if it is set close to maximum, it will eat up the battery very quickly. The most efficient way is to keep it in the middle, maybe a bit closer to the minimum (but still bright enough to read).
In some devices, there is a possibility to automatically adjust brightness, which comes in handy with different weather conditions.
Go to Settings > Display and Wallpaper (Screen) > Brightness
Huawei: How to troubleshoot Huawei P9 flickering display problem
If you’re having problems with your Huawei P9’s display, you might just be able to troubleshoot this just by these simple steps. Read on.
The purpose of this troubleshooting guide is for us to know what the problem is all about and why it occurs. We might be able to find out what causes the screen to flicker from time to time. That way, we may be able to find a solution that will fix the problem for good. That being said, here’s what you need to do about this problem.
Step 1: Make sure the flickering isn’t just a simple glitch
Glitches happen all the time and while they may appear to be serious issues, more often, they’re not. In fact, a glitch can be fixed by simple doing the forced reboot procedure that will refresh the phone’s memory and this is the first thing I want you to do.
Press and hold the Volume Down key and then press and hold Power key. Keep them pressed for ten seconds and your phone will reboot normally. Observe your phone to know if the screen still flickers and if so, then we might be dealing with a more serious issue with the firmware or the hardware. Move on to the next step in this case.
Step 2: Boot your P9 in Safe mode and observe
We have to isolate the problem at this point in our troubleshooting because it’s possible one or some of the third-party apps is causing the problem. So, to rule it out, reboot your phone in safe mode to temporarily disable apps you downloaded and installed on your own.
Turn off your Huawei P9.
Press and hold the Power key.
Once the Huawei P9 screen appears, release the Power key and immediately press and hold the Volume Down button.
If successful, you can see ‘Safe mode’ in the lower-left corner of the screen.
While the device is in this mode, observe closely to know if the screen still flickers and if the problem is fixed, then our suspicion that one or some of the third-party apps causes the problem is confirmed. Try to find the apps that might be causing the problem and then uninstall them one by one until the problem is fixed.
However, if the screen still flickers even in safe mode, then the third-party apps have nothing to do with the problem.
Step 3: Try to wipe the cache partition to see if it makes a difference
There are times when system caches used by the firmware become corrupt or obsolete. It could be one of the reasons why performance issues or even problems that have something to do with the hardware happen. Deleting those caches will force the phone to create new ones to replace them and in this case, it’s necessary. You can only delete system caches at once by booting your phone in recovery mode.
Turn off your Huawei P9.
Press and hold the Volume Up and the Power keys together.
When the Huawei logo appears, keep holding both keys until the screen turns black.
The screen may turn black for a second or two and you may release the keys at this point.
When you can see EMUI on the screen, it means you’ve reached your phone’s recovery system.
Using the Volume Down button, highlight “Wipe cache partition” and press the Power key to select it.
Confirm your action and wait for the phone to finish wiping off contents of the cache partition.
It may take for the phone to boot up a little longer but wait for it.
After wiping the cache partition, observe your phone closely to know if the screen is still flickering and if so, then the problem could be with the firmware or the hardware. You need to rule out the possibility that the problem is with the firmware by doing the next step.
Step 4: Reset your Huawei P9 to rule out the possibility of a firmware issue
If all else failed to fix the screen flickering issue on your Huawei P9, then it’s time you reset your device to finally rule out the possibility that this problem is due to an unknown firmware issue. If the problem still occurs after the reset, we can say the problem is with the hardware and you may need help from a technician to do further tests and even fix the phone is possible. But before that, make sure you backup all your files and data and then follow these steps:
Turn off your Huawei P9.
Press and hold the Volume Up and the Power keys together.
When the Huawei logo appears, keep holding both keys until the screen turns black.
The screen may turn black for a second or two and you may release the keys at this point.
When you can see EMUI on the screen, it means you’ve reached your phone’s recovery system.
Now, using the Volume Down button, highlight the option “Wipe data/factory reset” and then hit the power key to select it.
You will be brought to another screen that prompts “Confirm wipe off all user data?”
Highlight the option “Wipe data/factory reset” once again and then hit the Power key to select.
It may take a several seconds to complete the reset so wait for it until it’s done. You can actually see the progress on the screen.
Once the reset is completed, you will be brought back to EMUI screen.
Hit the Volume Up button to highlight “Reboot system now” option and then press the Power key to reboot your phone.
It may take for the phone to boot up a little longer but wait for it.
After the reset and the screen still flickers, you may need help from a technician to get it fixed.

Dual camera systems on smartphones have been around for several years now. Some of the earliest examples include the weird 3D camera on the HTC EVO 3D. Then it was HTC again who introduced it in a different form on the One m8. Then LG decided to drop in with its cool wide-angle lens with the G5 and the same year, Apple decided to take in the other direction by adding a telephoto lens on the iPhone 7 Plus. Meanwhile, Huawei had other ideas, with its Leica branded monochrome camera on the P9.
But just how many types of dual camera systems are out there and how do they differ from each other? Most importantly, are they any good or is it just a passing fad? Let’s find out.
The Depth Sensor
We will start with this as this is the most basic form of dual camera system. In this system, the primary camera is accompanied by a second camera whose only function is to 3D map the area in front of the camera. As you may know, we are able to see in 3D because we have two eyes with slightly different perspectives that help us convey depth, especially for things that are close to us.
The HTC One m8
The secondary camera in this system works similarly. With the second camera, the system can now tell roughly how far the objects in front of it are with respect to each other. This information is then used to separate the foreground subject from the background.
The most common use of this technique is to create a shallow depth of field effect. While it’s something that comes naturally to DSLR cameras with their big sensors and big lenses, the small smartphone cameras cannot achieve the same shallow depth of field. So instead, this technique is used to first figure out the borders of the foreground subject and then apply an iris blue effect on everything else. This gives the illusion of shallow depth of field.
Sample from the HTC One m8. Didn’t always work this well.
While sound in theory and occasionally in practice, this technique has its pitfalls. Unless your subject is a cardboard cutout, it will have depth to it and because this depth is not as much as the depth between the entire subject and the background, the camera occasionally ends up blurring the edges of the subject as well. Even when it does work reasonably well, it never quite looks natural, especially since most smartphone cameras that have this feature apply an even blur on everything in the background whereas with a DSLR, the intensity of the blur increases with the distance from the focus point.
Camera systems with a dedicated depth sensor is one of the rarest types of dual camera systems. The first popular use of it was seen on the HTC One m8 but these days only the most basic smartphones, such as the Honor 6X or the Lenovo K8 Plus, can be seen using a dedicated depth sensor lens.
The Monochrome Camera
A slightly more popular implementation of the secondary sensor is the monochrome camera. In this method, the primary camera is accompanied by a mostly identical secondary camera. Both cameras usually have identical sensors, apertures, lenses and focusing systems. The main and usually only difference between the two is that the second sensor lacks an RGB color filter. This means that the sensor cannot capture color information but on the upside, because there is one less thing blocking the sensor, the monochrome camera can capture more light.
Huawei P9
Every time you take a picture, the camera system combines the output of both cameras and layers them into one image. In theory, the two images when combined will have greater detail and reduced noise. Alternately, you can also just shoot from the monochrome camera and get slightly better image quality at the cost of all the color information.
One of the first examples of this system was the Huawei P9 and since then, few other devices have also shipped with this system. To us, the advantages of this system are nebulous at best. While sound in theory, we can’t really say for sure if the feature does really work as advertised. We have seen some good results with this system in the past but its hard to tell if it was the dual camera doing all the work or it was just good image processing system.
Monochrome image from P9
There is no real disadvantage to this system and we do appreciate that it’s the only one of the systems discussed here that tries to do anything about the actual image quality instead of adding additional features but still, we would rather take some zooming ability over marginally improved image quality.
The Wide-Angle Camera
Debuted first on the LG G5 early last year, the wide-angle camera is pretty much what it sounds like. To take LG’s example, the phone had a 16 megapixel, 29mm equivalent f1.8 primary camera and 8 megapixel, 12mm equivalent f2.4 secondary camera. The 12mm focal length gave the secondary camera a crazy wide field of view that allowed the user to capture a much wider area without having to move back or capture interesting perspectives afforded by such a wide-angle lens.
LG G5
We have mainly seen this on LG phones, with Motorola recently incorporating it in the X4, and we are fans of how it works. The wide-angle lens gives a very unique perspective that you simply don’t get at all on smartphone cameras and apart from having practical value (capturing a large group of people from up close) also lets you capture some really cool looking shots.
The early iterations of this system did have its disadvantages. On the G5 and V20, the ultra wide-angle lens image quality was nowhere near as good as the primary camera and also had significant barrel distortion that made it look like the footage from a GoPro with a fish-eye lens. However, LG has been steadily improving the system with every iteration and in its latest avatar on the V30, the secondary lens not only has highly respectable image quality but also significantly less distortion around the edges, making it far more useful.
Wide-angle on top and ultra wide-angle below from G5
With good implementation, this system does have the potential to be a really cool second camera system for particular scenarios and we wish more manufacturers adopted it.
The Telephoto Camera
The most common of all the dual camera systems today is the telephoto camera. In this, the primary camera is paired with a second camera that has a telephoto lens. As you can tell, this is the exact opposite of the wide-angle camera system, wherein it actually lets you zoom into your subject instead of zooming out.
Apple iPhone 7 Plus
Since the iPhone 7 Plus, manufacturers have stuck to using a 2x factor for the second telephoto lens. This means the secondary lens has twice the focal length of the primary lens, giving you an instant 2x optical zoom.
There are many advantages of this system. First is the most obvious, where you get 2x lossless optical zoom. Zooming on smartphones has largely been digital until now but with this you get to quickly move 2x closer to your subject with very little quality loss. Any further zooming is done digitally still but because the digital zoom is now being applied on top of 2x optical zoom, it gives much better results.
Wide-angle above and telephoto below from the iPhone 7 Plus
Shooting with a telephoto lens also has other advantages. Telephoto lenses are more suitable for portraits than wide angle as they have less distortion and is more flattering to the subject. Most manufacturers go one step ahead and also implement the background blur effect that we saw with the very first system we talked about today (the primary lens now acts as the depth sensor). The combination of a telephoto lens and background blur gives far superior results than just applying background blur on wide-angle images.
Of course, this system too has its disadvantages. So far none of the manufacturers have been able to get complete parity between the two cameras. When the iPhone 7 Plus launched last year, it had a much smaller aperture (f2.8) compared to the main camera (f1.8) and no OIS on the secondary sensor. The iPhone 8 Plus ships with similar arrangement (although the sensors are better this year) and even the iPhone X still has f2.4 for the second camera (although it does have OIS). The Note8 was the first phone with a telephoto camera to have OIS but even then it’s still f2.4 (compared to f1.7 on the main lens) and the second sensor is slightly worse even if it has the same resolution.
iPhone 8 Plus Portrait Mode with Studio Lighting
Due to this, there is generally a quality difference when shooting with the telephoto lens. It’s even worse in lowlight, where due to the small aperture, most manufacturers just choose to disable the telephoto camera entirely, and instead when the user taps the 2x button, the camera just does a 2x digital zoom on the primary wide-angle lens. Needless to say, any further zooming is also digitally done on the primary lens. There are ways to force the camera to use the second lens on some phones but the results are generally not worth it.
Still, most of these limitations seem to be temporary and something year after year advancements should take care of eventually. This is still by far the most practical solution of all the systems we discussed today. Not only does it give the user a much needed optical zoom ability but at a pinch also lets them take some pretty decent looking shallow depth of field images.
That’s pretty much it for the dual camera systems. Let us know in the comments which one do you prefer, and if you have any further queries or other topics you’d like us to discuss in the future.
Huawei shipped 100 million units in 2016 with more time to spare
Huawei made 100 million units overall shipment in 2015. This year, they made the same number with 2 and a half months still to go.
CHINA – Huawei launched the Nova smartphone at a special event.
They’ve got the event primarily for the announcement of a new device but a more news-worthy piece of information comes from the company’s sales.Huawei has already shipped more than 100 million smartphones worldwide for 2016.
To see what kind of an impact this means for Huawei, we have to know that Huawei shipped 100 million smartphones for the entire 2015. Now, it made it in less than ten months. The company still got 2 and a half months to bread their old sales record with the holidays looming around the corner.
Huawei previously announced it has sold more than 6 million Huawei P9 flagships and more than 1.5 million Honor smartphones. Its next big thing – the Mate 9 – is yet to be announced on November 3 and launched before this year ends, so you bet those millions of shipped smartphones will become even more by the end of 2016.
Huawei’s bestselling smartphone of 2016, the Huawei P9.
