Please this video record it's too short

Honestly this course is very basic. I have finished the whole trilogy and this course is the worst, is very basic.
By Denise Weiss on 5/28/2022
Another great course by one of the best instructors on Udemy! Alex is very clear and concise in his lectures and he keeps his students engaged in the topics. He covered both Android and IOS devices during the course. Alex provided me with absolutely great tools to safeguard my Android mobile devices. If you are looking to get a better understanding of mobile security and how to protect your mobile devices, this is the course for you.
By Jake Murphy on 3/10/2021
Another great course from Alexander Oni. This course teaches you the basics to keep your mobile devices secure. I thought I had a pretty good grasp of my mobile security, until this course. Thankfully, Alexander's courses are easy to follow along with and have plenty of practical examples. One of those practical examples showed me how exposed my device was. Thanks Alexander!
By Danet Leon on 10/29/2020
I truly enjoyed all 3 parts of this course. Lots of information to learn and practice at home or at work. Alex thank you so much for these courses. It gave me a better insight and how to apply the information with the devices we use day to day. Understanding some of the terminologies is also a great help. Mobile Security is as important as our computers .
By Camillia Jones on 10/1/2020
Loved this course. I completed parts 1 and 2. There were just 2 things that I think you need to address. This course is stated that it's for 2020, however, you're using a Samsung Galaxy S7 to show how to navigate certain security settings. Will you please update this part of the video with an updated android device? In the security settings I did not see the app permission monitor on the Lock screen & Security nor did I see the same settings for the security policy update. It may be that they're now in a different section or labeled differently. Could you also show how to do updates. I know you mentioned to do them, but you did not show how to do them. Perhaps you mentioned it in parts 1 or 2 and I don't recall. Seeing that this is for beginners I don't know everything, but I want to learn. Other than that, this course was excellent. You break everything down in layman terms. If you could update the things I just mentioned, I'll give you 5 stars. Keep up the good work. You're a great instructor and provide lots of useful information.

Like I said in the feedback near the end of the course, this has been the most useful course I have taken with Alex thus far. I learned a lot about making my Samsung Android phone more secure. I have done as much of the tips as possible. Just wanted to suggest that some of tips have changed since this video was made. It may be time to update this course since there are new security features.
By Theresa Emerick on 5/30/2020
I would venture to say that most people who begin using a mobile telephone, such as an Android or Apple device (for the very first time ever!) do so with very basic knowledge as to it's functions (call/text/internet access). This course would be an excellent supplement to the purchase of such devices. It provides basic information, along with tips and suggestions, that all responsible mobile device user's should know for cyber security purposes.
By Peter J Rivers on 1/19/2019
This course is very good for beginners in the security space for Mobile Devices. As network engineer, the concepts that were discussed are things that I deal with on an almost daily basis, but relating it to wireless/mobile devices was done well. I do not always know what works on devices that are not enterprise Routers/Switches/FWs/etc, so to get granular on the basics was very helpful to me. I will definitely be having my kids go through this course.
By Craig Culverwell on 1/1/2019
Alex you have done it again you have made another great course full of great explanations and information. As well as being fun as well. Well done with the practical exercise I was amazed to see how many apps I have on my device that I don't use anymore and are just taking up space as well as great tips how to choose apps and see that they are safe to load. maybe some more information on why apps require the permissions that they do. But it is a brand new course so with the help of the students taking the course new parts can be added at a later stage.
