I have been using my grand for more then a year now, it is the only cellphone I used during this period or you can say primary phone or daily driver and here is my experience-
(Rooted,Stock Rom 4.2.2)
Hardware side-
The side bezel is still holding that silver coating except from the part where the charging cable is plugged and some places near the back cover.
I would say that it fine.(Have never dropped the phone and hope to keep it that way)
Screen -
The screen is well protected by this scratch less screen guard (using it for more then 4 months) which gives a little sparkling effect which I find little annoying but is ok as I have used my cell without flipcover for like more then 1 month and still scratches can't be seen on the screen (Unless one looks closely for them).
The screen is quite big for my hands and after using this phone I feel that a 4.7 inch would be more suitable to me, also I feel that they have increased the screen size by expanding the breadth more then it should have been which make it a little uncomfortable to hold and gives it a cheap look(just my view).
Sim-
I have had 2 sims on my phone but never really used the second one except for a month or so, in my experience the phone becomes quite laggy when both sims are kept active and more so when you use your second sim for data and first for calls.
Switching between the sims gave lag of like 2 seconds and sometimes even more.
Hang-
When the remaining internal memory gets lower then 1gb the phone becomes real slow and near 700 mb or less left it hangs for like once or twice a day(in which case i had to reboot the phone by long pressing the power button)
I have to delete all useless apps(mostly games) as I do not like link2sd, gives mount script error on reboot and have got my nexus 7 for gaming and stuff and have put all my music(20 gb plus) amd titanium backup on my 64gb external card.
When the free internal memory is like 1.2gb or more the phone works fine.
Battery-
I use Greenify to stop apps that are less important from running in the background and consuming the battery.
I have ran this phone from 100% to 1% for 42 hours during which I made like 30min of phone calls and near to no use of internet(whenever used it was on my wifi) and rest of the time it was idle, the network was WCDMA ONLY on my BSNL sim, that was the highest I analyzed, maybe it can do better but I don't bother putting it to test.
Issues-
(Other then those mentioned above)
When continuously using the Samsung Keyboard for more then 5 minutes I experienced massive delay in keyboard, almost to the extent where I had to exit the app and restart, this was not one time thing as it went on to happen consecutively 3 more times.
(I was using Google Keep)
In also lags a little bit in general usage.
While using any app if I long press the home button most of the time the app I was last using is not present in the recent apps list,this is quite prominent and is noticed on a daily basis.
Now when I go to the home screen then go back to the recent apps the last app is still not in the recent apps section.
