I experience that iphone 4 is a future phone its battery life is better than any android phone but the problem is that you cannot download songs or vedio you can listen online any songs
the problem is that in iphone 4 is last upgraded to ios 7.1.2
if you want to download apps from app store most of the app requires ios 8,
ios 8.1, ios 9.4
which is not possible in iphone 4 to download such kind of apps
examples. youtube, hotstar
any many apps but I like iphone 4 because of its amazing features like hd facetime the most amazing fact about iphone 4 is lag, hang free.
you can its has a black glass body which look awesome and has a assistive touch features.thankyou
