Samsung phones, or in general Android phones, come with a lot of apps, tools, and shortcodes. These shortcodes are very useful in many ways, but sometimes they are not easily comprehensible.
One such code is “*#*#4636#*#*”. When you use this code, it will open up a menu that shows information about your phone’s data usage. One of the options in this menu is “Toggle DNS check.” But what does that mean, and what does it do?
Toggle DNS Check determines whether the DNS server address for the APN you are connected to is set up in DHCP.
Turning it ON prevents blank DNS server information from appearing and is likely to prevent your phone from connecting with that APN.
In this article, we will further look into what DNS is, and how it works, and will also look at some of the related questions regarding DNS.
Toggle DNS check
To understand this a bit more clearly, let’s just break the term. DNS stands for Domain Name System. It is a system that is used to convert a domain name into an IP address.
In simple words, DNS can be defined as the phonebook of the internet. DNS servers are used to store these domain names and their corresponding IP addresses.
So, the Toggle DNS check is basically a DNS-related setting on your phone. When you turn it ON, it means that the DNS server address for the APN you are connected to is set up in DHCP.
A blank DNS server will be permitted by turning it OFF (0.0.0.0 allowed). You won’t encounter this problem in normal use, as these settings only have an impact if you connect to a private APN. It is advised to keep it in the allowed 0.0.0.0 state.
It seems to be confusing, but if you drill down you will see that it is the same as allowing auto-configured DNS ( example 0.0.0.0) or even a custom DNS.
What is the cell info refresh rate?
The refresh rate can be defined as the number of times per second an image is displayed. The refresh rate of a phone’s display is how often the image on the screen is refreshed.
For example, a 60Hz refresh rate means that the image on the screen is refreshed 60 times per second. A higher refresh rate results in a smoother image.
Every smartphone display has a minimum refresh rate of 60Hz, which means that updates occur 60 times per second.
This refresh rate is the norm and was once the only one in use. However, smartphones with 90Hz, 120Hz, and even 144Hz refresh rates are already readily accessible.
What should my cell info refresh rate be set at?
The cell info refresh rate should be set at 60Hz. This is the minimum refresh rate for a smartphone and will result in a smooth image.
However, if you have a phone with a higher refresh rate, you can set it to that for an even smoother image.
If the refresh rate is kept at 90Hz or higher, a more smooth experience should be achievable. Swiping and scrolling through the menu ought to be simpler.
This may also help games with higher frame rates. On the other hand, bringing the frequency up to the industry-standard 60Hz frequency usually results in longer battery life.
I hope you found this article helpful. In theory, Toggle DNS Check is a DNS-related setting on your phone that when turned ON, the DNS server address for the APN you are connected to is set up in DHCP.
A blank DNS server will be permitted by turning it OFF (0.0.0.0 allowed). It is better. to keep it in the allowed 0.0.0.0 state.
