Inferences:
 
From above information,
 
In Case-1, the one who likes Asus sits on the 2nd left of Irfan & there must be one person sit between one who likes Asus and the one who likes Oppo as per statement. But if we observe the case-1, 10 seats are occupied by person or mobile phone which is not possible. Hence this case can be eliminated.
   
Case: 1 [Eliminated] Total occupied seats exceed 9.
Row – 1 (Person)  Harish     Edwin   Diwan
Mobile   Redmi   Moto Lenovo Sony
 
Mobile   Oppo One person should sit Asus Vivo Samsung
Row – 2 (Person)          Irfan
 
In Case-1-A, the one who likes Asus sits on the immediate left of Irfan, by this the seat which is on the immediate right of the one who likes Oppo becomes Vacant as per given statement and it is shown in seating.

In Case-2, the one who likes Asus sits on the 2nd left of Irfan & there must be one person sit between one who likes Asus and the one who likes Oppo as per statement. But if we observe the case-2, 10 seats are occupied by person or mobile phone which is not possible. Hence this case can be eliminated.

References:
 
1. The number of persons to the right of Edwin and the number of persons to the left of Francis are same.
 
2. Ashwin, who likes Micromax, is not sitting adjacent to any of the vacant seats.
 
3. Govind is an immediate neighbor of vacant seats.
 
4. Chandra sits right of Govind, who does not face south direction.
 
5. Bala likes neither Oppo nor Asus.
 
6. Vacant seats are not facing each other.

 
Inferences:
 
From above information,
 
With reference to 1st point, number of persons to the right of Edwin is 2. Because there should be 3 vacant seats in the arrangement. Therefore number of persons to the left of Francis must also be 2 in both case-1-A & Case-1-B
 
If we observe the case-1-A & Case-1-B, 8 seats are occupied either with person or mobile and the remaining one seat is filled by Ashwin, who likes Micromax phone. From this we clearly understood that, Bala, Govind, Chandra and Francis must like Oppo, Vivo, Asus and Moto but not necessarily in the same order. I.e. No new seats can be occupied by these 4 persons.
 
Now up to the given condition, let check the possibilities:
 
Note: Chandra sits right of Govind and both are facing north direction. Govind is an immediate neighbor of vacant seats.
 
Case: 1-A: To satisfy the reference point-1, Francis must like Asus; by this number of persons to the right of Edwin is 2. Therefore number of persons to the left of Francis is also 2. Then, Govind likes Oppo and Chandra likes Vivo. Then Bala must like Moto (Bala doesn’t like Oppo or Asus).
 
With the last hint we know that two vacant seats can't face each other, so the only left person Ashwin must face the vacant seat of row 2. So, the first and second vacant seats are there in the row 2, but there should be a total of 3 vacant seats as only 9 people are sitting, thus the third vacant seat is beside Ashwin, which will violate the 2nd reference point.
 
Both the vacant seats should be adjacent to Govind, with reference to the 3rd reference point which says that Govind is an immediate neighbor of vacant seats.
 
Case: 1-A [Eliminated] When Bala is immediate left of Edwin. No place for Ashwin to sit
Row – 1 (Person)  Harish Vacant Ashwin-X Edwin Bala Diwan
Mobile Redmi   Lenovo Moto Sony
 
Mobile Vacant Oppo Vacant Vivo Asus Samsung
Row – 2 (Person)  Govind Chandra Francis Irfan
   
Case: 1-B: To satisfy the reference point-1, Francis must like Asus; by this number of persons to the right of Edwin is 2. Therefore number of persons to the left of Francis is also 2. Then, Govind likes Oppo and Chandra likes Vivo. Then Bala must like Moto (Bala doesn’t like Oppo or Asus).
 
Neither vacant seats are facing each other nor Ashwin is a neighbor of vacant seat. All the conditions are satisfied.
 
Case: 1-B When Bala is immediate right of Edwin
Row – 1 (Person)  Harish Vacant Bala Edwin Ashwin Diwan
Mobile Redmi Moto Lenovo Micromax Sony
 
Mobile Vacant Oppo Vacant Vivo Asus Samsung
Row – 2 (Person)  Govind Chandra Francis Irfan
 
If we observe the case-2-A & Case-2-B 8 seats are occupied either with person or mobile and the remaining one seat is filled by Ashwin, who likes Micromax phone. From this we clearly understood that, Bala, Govind, Chandra and Francis must like Oppo, Vivo, Asus and Moto but not necessarily in the same order. I.e. No new seats can be occupied by these 4 persons
 
Chandra sits right of Govind and both are facing north direction. Govind is an immediate neighbor of vacant seats. But in both the cases only one seat can be filled by either Chandra or Govind. If Chandra or Govind sit in a new place in Row-2 (a seat which is not occupied by mobile phone), then total seats exceed 9 which is not possible. Hence both the following cases can be eliminated.
 
Case: 2-A [Eliminated] - Govind does not face south
Row – 1 (Person)  Irfan Francis   Vacant    
Mobile Samsung Asus Vivo Oppo  
 
Mobile Sony Moto Lenovo     Redmi
Row – 2 (Person)  Diwan   Edwin     Harish
 
Case: 2-B [Eliminated] -Govind does not face south
Row – 1 (Person)  Irfan     Vacant    
Mobile Samsung Asus Vivo Oppo  
 
Mobile Sony   Lenovo Moto   Redmi
Row – 2 (Person)  Diwan   Edwin     Harish
 
Clearly, only case 1-B satisfies all the given hints, thus the final arrangement will be obtained through Case 1-B.
 
Case: 1-B
Row – 1 (Person)  Harish Vacant Bala Edwin Ashwin Diwan
Mobile Redmi Moto Lenovo Micromax Sony
 
Mobile Vacant Oppo Vacant Vivo Asus Samsung
Row – 2 (Person)  Govind Chandra Francis Irfan

With reference to 1st point, number of persons to the right of Edwin is 2. Because there should be 3 vacant seats in the arrangement. Therefore number of persons to the left of Francis must also be 2 in both case-1-A & Case-1-B
 
If we observe the case-1-A & Case-1-B, 8 seats are occupied either with person or mobile and the remaining one seat is filled by Ashwin, who likes Micromax phone. From this we clearly understood that, Bala, Govind, Chandra and Francis must like Oppo, Vivo, Asus and Moto but not necessarily in the same order. I.e. No new seats can be occupied by these 4 persons.
 
Now up to the given condition, let check the possibilities:
 
Note: Chandra sits right of Govind and both are facing north direction. Govind is an immediate neighbor of vacant seats.
 
Case: 1-A: To satisfy the reference point-1, Francis must like Asus; by this number of persons to the right of Edwin is 2. Therefore number of persons to the left of Francis is also 2. Then, Govind likes Oppo and Chandra likes Vivo. Then Bala must like Moto (Bala doesn’t like Oppo or Asus).
 
With the last hint we know that two vacant seats can't face each other, so the only left person Ashwin must face the vacant seat of row 2. So, the first and second vacant seats are there in the row 2, but there should be a total of 3 vacant seats as only 9 people are sitting, thus the third vacant seat is beside Ashwin, which will violate the 2nd reference point.
 
Both the vacant seats should be adjacent to Govind, with reference to the 3rd reference point which says that Govind is an immediate neighbor of vacant seats.
 
Case: 1-A [Eliminated] When Bala is immediate left of Edwin. No place for Ashwin to sit

Case: 1-B: To satisfy the reference point-1, Francis must like Asus; by this number of persons to the right of Edwin is 2. Therefore number of persons to the left of Francis is also 2. Then, Govind likes Oppo and Chandra likes Vivo. Then Bala must like Moto (Bala doesn’t like Oppo or Asus).
 
Neither vacant seats are facing each other nor Ashwin is a neighbor of vacant seat. All the conditions are satisfied.

I.e. No new seats can be occupied by these 4 persons
 
Chandra sits right of Govind and both are facing north direction. Govind is an immediate neighbor of vacant seats. But in both the cases only one seat can be filled by either Chandra or Govind. If Chandra or Govind sit in a new place in Row-2 (a seat which is not occupied by mobile phone), then total seats exceed 9 which is not possible. Hence both the following cases can be eliminated.
