Part I: What Makes a Good Camera Phone?
Many criteria for good camera phones
It’s not that easy to choose the ideal smartphone these days. If there are special requirements for display, performance or camera, for example, you have to look carefully to see which mobile phone meets the requirements. If you are interested in a smartphone with a high-quality and versatile camera , you usually cannot avoid expensive devices . The manufacturers usually equip their flagships with the best lenses. There are a few aspects to consider here that are decisive for the quality of the camera.
Different lenses for every scenario
Versatile wide-angle lens
For a few years now, manufacturers have been using several sensors in their camera systems. When looking for a good camera phone, you should pay attention to the different lenses. Usually the main sensor is a normal wide-angle lens with a high resolution and a low aperture to take beautiful photos in all everyday scenarios. Combined with image stabilization, good autofocus and night mode, beautiful pictures of any subject can be taken even in moving scenes and in the dark. In most situations you will use the main lens , which is why you should pay particular attention to high quality.
Many smartphones use sensors from Sony. Examples are the extremely popular IMX586 and IMX686 with 48 and 64 megapixels, which are found in some smartphones from Samsung, Xiaomi, OnePlus and others. In addition, manufacturers such as Sony, Nokia, OnePlus and Huawei work with well-known brands from professional photography such as Zeiss, Hasselblad and Leica to build perfectly coordinated lenses and lenses that complement the sensors perfectly.
Long-distance shots with the telephoto lens
One lens that has now become standard is the telesensor . It has an optical zoom and is used to bring distant lenses closer. Before, it was only possible to enlarge an image section with a smartphone using the lossy digital zoom. This is not a real zoom lens, as you can only switch back and forth between the various sensors with fixed focal lengths . The telephoto lens has a longer focal length than the other sensors – usually over 50 mm. The lens is ideal for traveling and for portraits.
Some premium smartphones use so-called periscope telephoto lenses, which work with special light refraction and mirrors to allow even more optical zoom in the smallest of spaces and to bring you closer to your target subject.
The ultra-wide-angle lens is another sensor that is used in many cell phone cameras. In contrast to the telephoto lens, it offers a short focal length , usually less than 20 mm, and can capture large subjects such as landscapes.
Some cell phone cameras have a macro lens to capture small subjects such as insects or details of objects. These sensors are nice features for getting some nice close-ups . Currently, however, the lenses in most camera phones have a low resolution and are more of a gimmick.
A sensor that cannot be used for taking photos, but is built into many cell phones and supports the other lenses, is the depth sensor . It is often a time-of-flight camera (ToF) that measures the distance to objects and thus provides information on the depth of field. This can create a nice bokeh effect.
For the optimal detection of light values in order to be able to deliver even more details, some camera phones have a light-sensitive monochrome sensor . This does not record any color values and can therefore support the other lenses with precise brightness detection and HDR photos. Individual devices such as the Nokia 9 PureView even support native black and white photos . In contrast to sensors with color recognition, the color is not removed from the images afterwards, which ensures stronger and more “natural” results.
The popular messaging app WhatsApp is giving the opportunity to send greeting messages to many friends together on special days. From now on, a message can be sent to a maximum of 256 people through WhatsApp. For this the user does not have to create any group.
There is a preparation phase for this feature. This is called ‘Broadcast List‘. To do this, log in to WhatsApp and touch the three dots on the top right of the chat screen. There you have to choose the ‘New Broadcast’ option from the drop down.
Once there, it will show the list of numbers saved in the mobile. From here the user can choose the contact number of his choice. Here 256 numbers can be chosen together.
If the number is selected, an arrow will appear. Broadcast group can be created by pressing there. This time, if you send a message, it will go to everyone.
Even if you send a message to everyone at once, the recipients will not be able to understand it. It will appear that the message has been sent to everyone personally.

Since its launch in 2014, Telegram has become virtually the best alternative to WhatsApp, especially for users who spend a lot of time in front of a computer and who need to share files, since the platform is available for Windows, macOS, and Linux.
But, in addition, it does not need that our Phone is turned ON or that we have the right, as happens with WhatsApp Application. Also, unlike WhatsApp applications, you do not need a phone number to use the telegram. If you are ready to know how to use Telegram without phone number, please continue reading.
How the telegram works
WhatsApp is all end-to-end, end-to-end messages, so encrypted is not stored on any server and it cannot be used independently on other devices as we can do with Telegram.
Encrypts messages between Telegram Server and the application, not between applications like WhatsApp, so all messages are stored on Telegram Server encrypted and we can access them from any other application using data from the same account.
Telegram, via secret chat, uses the same method as WhatsApp encrypting end-to-end, device-to-device, without saving to the server and so we cannot continue those conversations from other devices from any other telegram application.
Use telegram without Phone number
While it is true that you do not need to have a phone number to use Telegram, it is important to remember that you must register if necessary. If we do not have a phone number, we will not be able to register for the application.
When the application started its journey, if we could register without using a phone number, but from Telegram Application, they were required a telephone number to prevent opening a spam account.
Once we register for the application, we do use Telegram without phone number, so we can use a prepaid number and forget it forever, the phone number is registered, it is associated with a nickname on the telegram application.
Once we have opened a Telegram account with a phone number, we will need to create a nickname. This nickname will be our I’d on the telegram platform, that is, it will be the name by which any other user can find us on the telegram.
Locally, the application does not allow other users to search us with our phone number, so Telegram is an ideal platform to meet new people and if we have any problems with them, block them directly so that they never contact us again. Maybe, since they don’t have our phone number.
As I commented in the previous section, the first thing we need is to have a phone number in hand, a phone number where we can get the confirmation code of the platform and register, we must enter the application.
We do not need to install the Telegram application on our mobile where we get the confirmation message, but if it needs to be in hand, since, without that code, we will never be able to register in this messaging application.
To create an account in Telegram follow the steps below.
Then the telegram App invites us to enter your country and your phone number.
Then, an SMS will be sent with the verification code on our phone which we must enter into the application.
If we want to use it on another computer, once we have created an account, we will not need a mobile phone with the corresponding phone number.
Create a nickname in the telegram
Once we have opened our Telegram account, we need to do is generate a nickname as an identifier, it will be the name by which other users will be able to identify us on the platform.
We can also set our real names, which will be used to introduce ourselves in the chat, although through this, no one will find them on our platform. Once we have created the alias, we can start using the application.
Telegram allows us to manage up to 3 accounts, all with different phone numbers and different nicknames. It allows us to use different nicknames depending on who we want to establish a relationship with and wants to permanently cancel or change at a given moment.
That way, when it comes to our family, we can use our established nickname, and if it’s about a group of people we don’t know personally, if we start to suffer any kind of harassment or if we want to forget this secondary account completely, close the account. For we can use a different.
Don’t have a phone number to register with Telegram?
This is a way to use Telegram without phone number, since you can use any one of the various applications available in both the Play Store and App Store that allow us to use virtual numbers for free for a limited time.
And I’m saying for a limited time, as we have explained, you only need to use a phone number once real, the number where the platform confirmation message is received. From that moment on, we will no longer need a smartphone or a virtual number to receive telegram SMS.
Install Telegram on other devices
Once registered, to log in to our Telegram account, we must enter the phone number (shown in the Telegram configuration section) in the Telegram application associated with that account, to receive a confirmation message.
This message is received in the Telegram application that we have already installed on another device, not via SMS to the corresponding phone number, so it does not need to be virtual or prepaid.
