I have been using phone for many years , the phone is lagging a lot but shows no further update for SMJ700F model .
The issue is it lags a lot . And apps are not responding frequently.
I don't know whether it is happening with me only or with other users too.
I will only say that j7 16 need security updates...thats it becoz last main upgrade we got on jan 2019 then after we didn't got no updates....so its urgent......Samsung has to understand the things what users wants with the device.
