The unfortunate reality is that of most of us believe that a smartphone whose camera has more megapixel takes better pictures than those with few
megapixel. However this isn’t always the case. This is because you can’t be able to note any difference in resolutiontaken by two different phone cameras, since most screens you will be viewing them on are not capable of displaying the
range of megapixels it supports.

Let’s  say that anything bigger than 8 megapixels tends to
be only helpful for cropping. What I’m saying is that a smartphone taking images of 12 megapixels  can be cropped by approximately 50 percent and its resolution will still be as high as a 4K TV.

Here are some factors to consider if you want the best of the best out of your camera.

P.S – I might get into a little bit of Physics to explain these factors but don’t worry it won’t be too complex to understand

Sensor size

The Sensor size represents a lot of important values regarding the camera such as the necessary focal length, the crop factor, and its f-number. Most OEMs have that figured, leaving the only vital thing you should worry about: the light
intensity gathering properties of your camera’s sensor.

This is a bit easy to understand. A large sensor has more area for light to penetrate giving a greater capability to gather the light.

Pixel size
The pixel size comes handy in measuring how larger individual photodetectors are in a CMOS sensor. Pixel size for a
smartphone camera fits in a narrow range that’s between one and two microns or micrometers (abbreviated as µm) in either the vertical or horizontal direction. The larger it is, the more light each pixel will collect. That’s why the HTC One M8’s camera with 2.0 µm performs better than in dark conditions than the Galaxy S5 that has 1.12 µm pixels. This
is simply because the M8’s pixels are a obviously larger and can capture more light. In summary , a camera with a high pixel size tends to capture more light than that with a lower pixel size.

Aperture size

Another spec to look is the aperture size that is represented
by f divided by a number (eg. f/2.0). Since ‘f value is divided by’ the setup, this is one of the rare camera specs where a
small number produces a better image than a larger one.
The key benefit of a wider aperture is that you the camera
will take better low-light photos. This is because a wider aperture lets more light to be captured at once when taking a
picture. You should keep in mind that a smaller number means a wider aperture.

Image Stabilization.

Image stabilization is either listed as OIS or EIS. This means Optimal Image Stabilization and Electronic Image
Stabilization.

OIS technology means that the camera sensor moves physically to compensate for unexpected shaking while holding your smartphone. If you are walking when you are recording a video, for example, the steps you take shake the
camera. However, OIS ensure that the sensor remains steady even if the rest of your smartphone shakes.

Unfortunately the downside of the OIS is that the hardware required tends to be
costly and takes up the previous space, hence it is not included in many smartphones . Instead, most smartphones use EIS to try and achieve the same effect. EIS works by stretching, cropping, and changing perspective on individual frames which make up a video.

In general, it is much better to have a camera that is running OIS since stretching and cropping can reduce quality or create a ‘Jello effect ’ in videos.

There was a time 4GB of space meant a lot of space but as we moved into
a new generation of smartphones, aspects such as the camera, video quality, apps, and file sizes has increased dramatically.

Android Chapter 7 vs 7 : Verily I say unto you, brethren ‘ Any Android device with a storage capacity less than 16GB is an abomination, so I advise you to flee’

Here are a few ways that can help you to free up space on your Android smartphone and reclaim those valuable gigs.

Why Your Device Storage Is Always Smaller Than Specified

Some people using a 128GB Android device don’t even bother about storage capacity filling up. On the other hand, the poor souls with 16GB and 8GB internal storage tend to count every single megabyte. However, you might have noticed that even in new Smartphones with 16Gb memory , the available memory is no more than 12GB.

Is there a way to get all 16GB of storage space?

The answer is no because manufacturers tend to play with numbers when it comes to providing internal storage. If you are given 16GB of storage at the rate of 1000MB = 1GB, the Android system calculates the storage using binary, where 1024MB = 1GB.

Moreover, there is around 2GB of internal storage space that the Android OS takes up, which is the heart of your device. Hence, there is no way to increase the total internal storage capacity to more than what you see in the Storage menu of the Settings app.

#1. Remove Unimportant Apps And Use Lite App Versions

Unimportant apps could be using up a fair amount of storage space that you desperately need. For instance, Facebook and Messenger uses up almost 500MB of your device storage, which can be quite the blow on a device with low memory. You can simply switch to the Lite version of the apps which use less than 3mb. Shazam, Skype and Twitter also have Lite versions.

Apart from the apps that you have installed, there are some apps that the smartphone manufacturers try to force down your throat

These apps are almost useless to the user, and brands like Samsung are guilty of this. You can find the Galaxy Apps, S Health, Flipboard and many other irrelevant apps on their devices.

If you aren’t too keen on removing these bloatware apps entirely by rooting your Android device, disabling them is the next best thing. Simply head over to the Applications menu in the Settings, navigate to these bloatware apps and use “Disable” to render these bloatware apps useless.

#2.Stream Movies Don’t Download

I know data subscription is sometimes expensive but most times discretion is the greater part of valor. Streaming a movie will save you more storage space than downloading it. The only extra data you may use up due to streaming is due to the buffer but if your Internet speed is very good you’ll only use up the exact amount you use for downloading the movie.

If you’re really concerned about your Android storage space running out, hoarding movies on your device’s internal storage won’t just take away precious space, but will slow down the system drastically.

#3 Move Your Files To The Cloud

Backing up your pictures to the cloud will save a lot of storage space.

To make things easier, Android OS offers an automatic backup in the Google photos app. From the Google Photos app, head over to the menu option and select “Free Up Space”. This screen will alert you on how many pictures have been backup up to your Google account and how many images can now be safely deleted.

Apart from photos and videos, you can back up large documents directly to your Google Drive account and access them online, without sacrificing the internal storage space. Since a single Google account offers 15GB of free storage, you can add multiple Google accounts, back up your media content and enjoy virtually limitless space.

There aren’t many OCR apps on android. Of the few that are available, Google Goggles is the most popular one. It’s entirely free and does exactly what it promises – copy text from a picture and paste it elsewhere.

Main features

Google Goggles converts an image of text to actual text that you can copy, paste and manipulate in any other way.It can translate the resulting text into many different languages.It can recognize business cards and add them to your Android device as contacts. This whole process just takes a single tap.

Google Goggles cannot precisely be described as a perfect OCR app, but it delivers quite well. It converts any image into copyable text. You can then paste this text into a document editor, your email app, your note-taking app, SMS, or just about anything else. It easily recognizes business cards and automatically adds the details to your contacts. It’s also able to translate text into tons of languages.

Other OCR Apps

There aren’t a lot of competitors to Google Goggles on the Android marketplace. The second best app that you can use to convert images to text is ScanDoc Document Reader. This scanner channels the resulting text into many apps on your device, with just a single click. Unlike Google Goggles, though, the app doesn’t perform well when it comes to doing everything it promises to do since there are occasional failures sending the text to apps such as Dropbox (at least for us). They’ll probably fix these bugs but it also isn’t free. The interface also doesn’t come across the board as intriguing. However, if you find that Google Goggles isn’t precisely what you want, ScanDoc might work for you.

Google Docs is also equipped with an OCR feature that works pretty much the same. The main advantage of the Google Docs OCR feature is that it recognizes line breaks, which makes the resulting text presentation much more enticing. But since it’s part of Google Docs and not really a specific-OCR app, it doesn’t have as much versatility as the other apps described above. It saves text directly to Google Docs, so if you need the text elsewhere, you’ll have to manually copy and paste.

There’s also a selection of document scanning apps available on Android, but these are not truly OCR. Rather than convert text on a picture into editable text, most of them turn it into a PDF document. That means you have no capacity to edit the text or use it with any of your other apps such as SMS and any document editors. However, this can be a useful functionality if you’re looking to capture details and email them in the form of PDF. CamScanner is just about the most awesome document scanner there is for now. You can send the resulting PDF to multiple apps, including Google Docs and Dropbox.

Another decent app is Document Scanner, which lets you use the OCR capabilities of Evernote and Google Docs, but isn’t quite as fast or effective as Goggles.

And it’s works pretty well.  Now you can easily copy things from an already typed document without retyping it.. No stress..

Enjoy
