DiagMonAgent – The troubleshooting designed for Samsung smartphones

    Hey Samsung users! This is Piyush Bhujbal. I have another tool for you that can make your problem-solving more helpful. Creating the most helpful tools has always been an ambition for Samsung. They are just doing their task very well. When there is a technical problem related to something, the aim is to find its solution. For that purpose, a troubleshooter is needed. Many a time this happens, when there is a total mess up in the phone. So Samsung designed a troubleshooter called DiagMonAgent. Its abbreviation is Diagnostic Monitor Agent.

    Handling multitasking is a complex job for a device. When it comes to Android development this becomes tougher. Samsung received a lot of complaints from the customers related to phone hangs, no space left, etc. In this article, we will be tracking the problems related to Samsung smartphones and this tool.

What is DiagMonAgent for?

    We face a lot more problems in day-to-day life. Like, say, if you are going cycling every morning. The tire punctures suddenly, what to do? As it is early morning so, no shops are open. Set back to home walking along. Some problems need experts. You cannot repair the punctured tire yourself. In the same way, the issue related to your phone needs a person or a toolkit. To fetch a repairer is tedious work. But, a pre-installed toolkit in your phone can do it with one tap.

     This implementation first came in the computer fields. The software engineers came p with an idea to build a system mechanic within the system. A healer that will help to remove functional interruptions.  If a user knows the OS inside the machine very well then a troubleshooter is also present. For example: when Windows PCs run into an issue the system automatically runs the Windows Diagnostic Centre. This toolkit developed by Microsoft automatically detects the issues when the windows machine is booted up.
