Finally, Chat application integrated with messaging application on Android smartphones, replacing the SMS of Google has also been set to test after more than 1 year of introduction and no credit. Google recently announced that Chat will be tested at the end of June in the UK and France.
Introduced from April 2018, the RCS (Rich Communication Services) application replacing this Android-based SMS has taken a relatively difficult year, not because of the problems in the service development process, but because of telecommunication networks. They do not want a low-cost alternative service, which threatens their revenue from SMS. As a result, Google must implement this service on its own, not relying on any other networks. After a trial period in England and France, Google may deploy this service to the world, when you use Android smartphones to message each other comfortably without using services from the side. third like Messenger of Facebook, Viber or WhatsApp.
If you compare Chat and iMessage, it's a bit lame, because the way Chat works is not the same. The nature of iMessage does not use RCS technology at all, because at the present time, the biggest problem of the RCS platform is that the messages that users send to each other are not two-way encrypted (end-to-end encryption). Currently iMessage, WhatsApp, Signal and Telegram are all encoded as such. Even Facebook has announced that all of its messaging services will also be fully encrypted, from the Instagram chat application to Facebook Messenger. Suddenly, Google Chat has not been released, causing many people to worry about privacy and data security.
How will Google RCS Chat work?
RCS is a messaging protocol that most carriers around the world agree that it will completely replace SMS. This protocol supports most of the features that you use Messenger or iMessage in, such as showing whether or not the other party has read the message, allowing you to attach large files, and Notifying the other party that the message is being edited, etc. And again, RCS does not have it, or rather does not have the ability to encrypt two-way messages.
The RCS application Google developed for Android is named Chat, which sounds easier than the Rich Communication Services concept that it relies on to operate. Like many other applications, including Facebook, every time there is a new update, the application will gradually deploy to several areas at the same time, until everyone is updated, not snap a finger. all are upgraded applications. Google's chat is the same. When you open the messaging application on your Android phone, if you are upgraded to Chat, the screen will ask whether the user wants to use this service or not. If Apple automatically updates iMessage for iPhone, if you do not want to turn off in Settings, then Google will ask before updating Chat for Android.
More specifically, these are some things you need to know:
– If you see the Chat message box, select Yes to activate Google's RCS service. If you are texting people who are also using the RCS service, the messaging application will change from Messages to Chat.
– Chat application has security messages, but not two-way encryption. This means that the RCS service provider, here is Google, can read all the messages sent to each other. However, Google said that as soon as the message is sent to the other end, they will delete the trace of that message on the Google server.
– Chat application will work with all devices supporting RCS Universal Profile, not necessarily sharing applications deployed by Google.
There is a little problem with RCS Chat. It does not have a database that lists users of these services and those who do not. Meanwhile with iMessage, Apple uses the central database called Apple Identity Service, which determines whether a user is using iMessage.
RCS does not work so easily, because this model involves many operators managing server systems that send and receive messages for other subscribers. This makes RCS more complicated, but thus avoids proprietary issues, when a large system that replaces SMS is not controlled by a single company.
Since there is no central database like Apple, and there are too many devices using Android, the Chat application sends a direct message to the device to "ask" whether the user supports RCS. The phone will automatically reply to this message without asking your opinion. Product Director of Google Messages, Drew Rowny, said that if iMessage uses a server to operate, then Google's RCS Chat uses a "point-driven" model, meaning that there is no need for carriers that Google can freely deploy this service to areas and devices they want.
If a network operator wants to deploy the RCS service to their subscribers, Google will let them be responsible for user data and messages. This means that in the future, if carriers support RCS on Android devices, you will have to monitor specifically whether the network operator or Google manages the Chat application you are using. Until RCS officially supports 2-way message encryption security, you can always psychologize if using this messaging application, the carrier and Google will also read the message.
Why does Google have to release RCS Chat?
Until now, operators are still responsible for supporting RCS messaging on Android devices, thinking for the same messaging application based on phone and SIM numbers, which is still the service of the network, not of Google. After years of trouble in creating a generic messaging platform, planning the perfect ecosystem of services Google has, Google is now quite determined to RCS Chat.
The difficulty for Google is that with the messaging application using the identifier, Google will have to work with carriers, and not all carriers will cooperate, and not all carriers will support Universal Profile. to deploy RCS. Take, for example, T-Mobile, the 3A Pixel machines they sell that do not support RCS. So the problem arises when you want a more convenient messaging application than SMS. iMessage is only available on Apple devices, while on Android, there are only third-party apps, such as Zalo, Messenger or Viber, and not everyone using Android smartphones uses those apps. RCS promises to be Google's answer to Apple's iMessage, but it is not easy to answer in a fair way.
Currently, about 75% of smartphones worldwide run Android, and Google is slowly updating the RCS Chat, they will be at a disadvantage. Google argues that the RCS standard is not owned by them, but by the GSMA network association, and Google is just trying to apply it. They did not make it difficult for telecom operators and forced them to support RCS, but at the same time they were also anxious and frustrated when the upgrade speed to new messaging standards was too slow, more than 1 year has not seen RCS to Android.
