How To Activate Grayscale Mode On Android Phones To Save Battery



Apart from the awesome Ambient Display that helps you view
notifications all the time without draining power, Samsung has other tricks up its sleeves. In order to make the most out
of its power-saving AMOLED display, some Galaxy devices
come with a Grayscale Mode. While Grayscale Mode on any
Android device isn’t a direct possibility, there is a way around it.

when portraying black and white colors, the Grayscale Mode
helps you get more juice out of each charge. To get

Vulnerability in RCS messaging could compromise your bank details




German security company SRLabs has recently discovered a serious security breach that could replace SMS. According to their findings, the RCS protocol has a vulnerability that allows your data to be intercepted.

Hackers could exploit this vulnerability locally or remotely. Among the information they can intercept, we have unique codes that are sent by message in two-factor authentication systems.

One of the applications of these unique codes is in the authorization of bank transactions. This means that in extreme cases your bank details could be compromised due to this vulnerability.


Android messaging should improve your domain verification system

As SRLabs points out, the most popular application supporting RCS technology is currently Android Messaging. According to its findings, this application does not properly verify domains.

This means that miscreants can spoof caller ID or DNS. Something that could mislead users and provide information they shouldn’t.

Coincidentally or not, Google revealed this week that it will accredit message senders in your app. The idea is for companies to register their contact numbers with Google so that they can validate them when communicating with users. A measure that will certainly reduce the impact of this vulnerability.

What is RCS and its differences from SMS

The acronym RCS stands for Rich Communication Service. Briefly, this protocol allows messages to be sent over the internet. The SMS protocol uses cellular networks to send messages.
