In India also there is BSc in Electronics and MSc in Electronics
There is indeed, but not in all universities. And it leans towards engineering.
Classically speaking there is no such thing as "Electronics Engineering". The circuit design using Electronic components is not different at all on a basic level compared to Electrical Engineering.
Yes, these are broad fields. But design of systems and circuitry is the domain of Electrical Engineering and indeed you will see most research in circuitry, systems and telecommunication comes from various Electrical Engineering departments around the world as that's what Electronics Engineering really is: A subset of Electrical Engineering.
"Electronics" is the study of motion of electron and devices that utilize the results of said studies. As such any electronic device falls into this area, as well as certain sensors and instrumentation, etc. Electronics is a science because it is directly tied to the laws of physics. Most electronics engineers today have little idea how things like thermodynamics, electromagnetics, mechanics, statistical mechanics and optics influence the working of devices and indeed the progress of technology in their field. And how many electronics engineers (or even the people with BSc and MSc in Electronics) in India know the basics of solid state physics and condensed matter physics? Things like bandgaps, energy bands, molecular orbitals? People say it's unnecessary, but if you're designing and modern electronic device or even fabricating/designing a chip on a process of specific width, all of this comes into play (will not go into details here).
Today, around the world: The theoretical side of electronics is mostly investigated by physicists, with some electrical engineers also doing the work. In India, there are few opportunities even in the few cases when the equipment is there mainly because engineering departments are always geared towards circuitry rather than doing the research.
Because Electronics involves, in general, a lot of research and analysis, it is a branch of applied science. The circuitry part is what constitutes the engineering part of it, and it is easily done by electrical engineers as well. This is why you don't frequently see "Electronics Engineering" as a separate department in scientifically developed nations: Because it is an applied science.
And even though universities do good work in both aspects, the fact of the matter is this. If I work on high-quality sensors, precision instrumentation and nano-devices as part of a thesis in a science department, it is thought of as "changing the field" because your ultimate degree in such a case is in science. As a result, it is extremely difficult for a "science" guy to switch into "engineering" (or vice-versa) because the Indian system
specifically discriminates. In today's complex ICs with their ultra-thin silicon wafer manufacturing process, the properties of the process, the wafer dimensions are equally important.
Also, the classical circuit theory laws really don't hold under specific circumstances, in which case you are better off directly regulating the flow of electrons using the laws of physics instead of the laws of electrical engineering (e.g. Microwave Engineering and Accelerator Physics, both also applied sciences for similar reasons).
So what's wrong with our system? It has no direction. Electronics the "applied science" has not been differentiated from the "practical" circuit side of Electronics. Both the BSc/MSc courses and the BTech/MTech courses have very similar syllabi with not a lot of difference between them. Ultimately they all end up in an engineering department and the research usually focuses on applications rather than devices.
There are two problems with this approach: The first is that industry doesn't recognize the two as being equivalent, even though they are, and the second is that someone who is interested in the science part of it should not be forced to end up in the engineering part of it (and vice versa).
That is why "Electronics Engineering" should be always the domain of Electrical Engineers. Because they can still do the job and do it very well, while still creating scope for physicists and applied science to get jobs as well as perform research.

Here you will be taught from the scratch. As of Engineering, it is a professional course and actually industry oriented courses.
The problem is that Electronics Engineering as a separate branch is not necessary for any industry. All circuitry work can be done by Electrical Engineers without any issue and the more complicated problems generally fall into the domain of computer science, computer engineering or applied science/applied physics (assuming only a B.Tech level education).
What this system does is limit the scope rather than enhance the scope by means of super-specialization, removing any and all scope for interdisciplinary education. For example, because of this very branch a lot of Electrical Engineers who may be interested and good at circuit design will not be the first preferred option because the Indian industry thinks an "Electronics Engineer" is better for the job when it is just not true.
Similar example: An Electronics Engineer who is interested in Electrical Machines and Power Electronics will have just as hard a time finding a job doing something like that because people always think this is more suited for an "Electrical Engineer". Again, not true. This interferes with the freedom of which job the person wants to apply to.
More importantly, it limits the scope for science graduates/postgraduates. Why do you need an engineer for modeling and simulation of a control system when someone specialized in mathematical physics or applied mathematics can do the job just as well? Control Systems are basically just mathematical models of practical systems. Similarly, why do I need an engineer to work on sensors and instrumentation when a physicist can also do the job just as well?
Finally, I also want to say not everyone joins a course for the prospects of a good job and work. Some are actually interested in what they are studying and it is this type of candidate that you want studying in your college. Tomorrow they should not be deprived of opportunities because of the name of the degree in which they graduated. Industry needs to realize science and engineering are very close, that you need both to progress in innovation, research as well as getting a competitive product out, and that a degree is a degree: no such thing as "professional" and non-professional degree. I haven't said anything against other Engineering branches because they do not overlap with the sciences: only Electronics has this problem.
