That phone was a gem! Lasted for years.A long time ago, I know, but when I bought my first smart phone, a Samsung Galaxy Mega 6.3
Buying second handed phones from a genuine known shop is also what I sometimes do. Much cheaper while having a good condition..I worked out that I could actually buy a phone from Amazon, put the same money in a savings account to buy another in 2 years and have enough left over for £5 of allowances per month, all for the same or less money than the price of a contract then on sale at the likes of phones4u.
So that is what I did.
