Before I proceed I will like to state clearly that this article is a continuation of an already existing four part series on ” understanding mobile device specification for dummies”. You might want to read that up before joining our part two bandwagon. But hey! That’s just an idea, you can flow along just well if you follow quite attentively. In the first part we discussed; naming conventions, operating system,processor etcetera. Now let’s dive into:
RAM simply means Random Access Memory. This is the memory that the different phone apps and the data it is using is stored while running. RAM is a fast but volatile memory, so volatile we could say its on a life supporting machine. Why life supporting machine? Well its because once the power goes off, our dear little RAM becomes “brain dead”. Every bit of data goes down the drain. Think of RAM as a huge filling cabinet inside your mobile device that keeps things ready for the processor.it is infinitely (almost) re-writable, very fast, and used differently by different operating systems. Many of you guys may understand what it is, how it works, and what I’m explaining, but so my “not so geeky” and the “extremely not so geeky” readers can follow lets get down to the basics.
If you plan on getting your next mobile device based on RAM performance you might want to go for a RAM with larger capacity. 512mb RAM is good, but 1Gb is better,2gb is more better and 4gb is the best of the four. Larger RAM size means you can load more apps and apps data at the same time without your mobile device having “seizures” or more simply; without it hanging. So if you are a multitasking kind of guy or more like a game freak, you might want to budget for the following devices;
Samsung Galaxy Note 3 – 3gb
Asus ZenFone 2 – 4gb
Samsung Galaxy Note_5 – 4gb
Exynos 7422 – 4gb
OnePlus 2 – 4gb.
For many people, a phone’s cameras are one of the biggest priorities when choosing a new phone. Since you carry your phone everywhere, you’re more likely to use it as a camera than your traditional compact camera. The gist is that smart phones have become very talented at taking pictures and shooting videos over the years, but dealing with camera specs have unfortunately gotten more complicated. Almighty Nokia kept us continually wowified with her flagship 41mp camera Nokia lumia 1020 and Sony continually curiously immersed with their 21mp camera xperia Z1 making phones with 4mp and 8mp Look like cold war relics fit for the museum. It’s however important to note that just because one camera has more megapixels than another doesn’t necessarily make it a better camera; That merely means it can take a larger photo.
So if you print a picture taken with an 8-megapixel camera, it will be smaller than a 16-megapixel shot. A higher megapixel count also means you can zoom closer into an image before it starts looking pixelated. So how does one really identify a good camera? look out for cameras with good;
-details at distance: the amount of photo details the camera can capture at a fair distance.
-color details at distance: the color details of photo a camera can capture at a fair distance
-close up details:quality of photo a camera can capture at a very close range.
-Portrait photo: clearity of portrait photo a camera can capture
-low lighting image: how a camera handles low lighting situation etcetera.
Like I said earlier, as mobile device camera becomes more talented….. it becomes more complicated to deal with them. The shady details provided for camera spec’s above barely scratches the important points, I intend to dive more intensely into it on part three of these series.
We all probably have been seeing display type on the spec’s label of mobile devices. We’ve probably also come across names like TFT,OLED,resistive etcetera. There is no magic formula to making a sense of this sometimes “not so familiar” names, just a little geek’s logic. So logically, let’s assume for the meantime that for some reason we are all geeks (there is no chance on earth that’s going to happen), at least theoretically, and here goes the geek logic;
There are lot of display types used in mobile devices. They can be either color or monochrome. Monochrome displays can be alphanumeric or graphic.Alphanumeric displays can show only symbols with a constant size (remember that boring Nokia 3110 display?), while graphic displays can show fonts of different sizes and animations. The color displays include CSTN, TFT, TFD and OLED with a predominant use of TFT displays in current mobile llineups.
CSTN- color super twisted nematic; bad image quality, bad response time, comes cheap, saves battery.
TFT-thin film transistor; better image quality, better response time, less cheaper, consumes more battery.
TFD-thin film diode;excellent image quality,very quick response time, saves battery, comes fairly costly.
OLED-organic light emitting diode;thinner, lighter,brighter,better viewing angles,quick response time
There are also two types of touchscreen displays – capacitive and resistive, which are both based on TFT technology.
CAPACITIVE touchscreens work by sensing the electrical properties of the human body, while RESISTIVE ones operate by sensing direct pressure applied by the user.
The RESISTIVE type can be activated by pressing not only with human skin but also with a stylus and thus allow handwriting recognition input. If you’re looking forward to getting your next device based on Display type, you might want to a little additional “heads down” research.
Obviously before the 2,3 and 4G network came into the game, there was 1G , but believe me when I say you don’t want to go there. Not only was 1G network terribly bad and unreliable, the best data service it could offer was just SMS. Luckily for everyone things have changed.G in 2G, 3G and 4G stands for the
“Generation” of the mobile network. These generation of mobile network are loosely defined but the generally entail comparison of data speed, voice clarity,always-on data access etc. A higher number before the ‘G’ means more power to send out and receive more information and therefore the ability to achieve a higher efficiency through the wireless network. If you love streaming videos with your device, you might want to go for phones with 3G nnetwork with data speeds capped Between 384kbps and 2Mbps. For a more “bad ass” experience 4G network with data speeds capped between 100mbps and a whooping 1gbps will do the job.
