The galaxy e7 of samsung launched in 2015 was great nd supperb. It has 2GB RAM 16GB ROM 2.3ghz processor 13/5MP cammera network 3G with 5.5 FHD amoled display.
It was good in 2015 however I used it for 3 months but unfortunately it does not support 4G LTE, so some users may face lacks for it.
Also 2016’s smartphones have fingerprint scanner but e7 don t have fingerprint scanner.
so in modern use it may lack.
