Ooo, I think it's a hardware problem. I am sharing about my experience. I had bought a GalaxyJ7NXT in 2018. After using around 9-10 months, I observed a charging issue. The issue was, after getting 88% charge it automatically decrease 1 by 1. In the beginning it was 1-2 days in a week and I had no care on it. In few weeks it increased to 3-4 days in a week. Then I went to nearest authorised samsung service centre and I told them about the charging issue. They checked and told me that there is no issue. Next day I faced the same problem again. I went to the service centre ,they took my phone after few formalities. After 1 days, I got a phone call from the service centre. Next day I took my phone. They said they have changed the total motherboard and the battery also. After this I used the phone 2 years without any issue. It was under the warranty period so it was totally free of cost. I want to give rating 10/10 for after sell service.
