So in other word, the sim slot is in working condition upon delivery.
The sim slot can be easily damaged upon removing & re-insert of the sim card.
The sim slot is not cover under manufacturer defect, as remove & re-insert may be cause.
This is what the service staff told me when i had this problem.
And what more is that phone & box imei are different.

i am going to buy samsung galaxy J1..
it is from vietnam and has 1gb ram 5 n 2mp back n front camera..
so i want to know is it original or not?
because at this web i saw J1 specifications which are quiet different from the 1 i am talking about although i had also heared that samsung mobiles made in vietnam are first copy of originals.
Any expert advice?
This J1ace and J2 are a facade. i have bought both in one row, they produce excess heat, you find those 3 fingures we normally use for swiping developing a consistent irritation from the burning . When you are not using the phone your palm is okay and once you resume its unbearable. I have used other phones such as Lumia 800 and the nokia family but have neve r encountered this problem.

If nothing wrong with the phone, Samsung service center will tell you what to do, no repair required.

Your decision, not mine.

If no change, then uninstall the app.
Finally, install the app. Do not change any setting yet. Use default setting.
Reset may not help as it will use the same apps.
Reset used back those apps that come factory preloaded.
By uninstall, and later install, the apps & phone could sync properly.
