Coming from Xiaomi Redmi Note 4 to this Samsung A7 2018.. I can honestly say.. :
1. Taller screen, super amoled, no notch. Superb.
2. Finally get the 4G+ (and VoLTE2) coverage, displayed at the status bar.
3. 128gb man! With an expansion slot for micro sd!
4. Camera is stunning, at least for me.. it's been awhile since I last played with mobile photography eg nokia 1020 back in 2013. Triple rear cams + front 24mp.. marvelous!
5. So far, never encountered any lags or crashes. Smooth all the way.
* charged from 1%-100% took around 2h19m.. for a 3300mAh is too long. My RN4 with 4100mAh which doesn't support quick charge as well only took 1h10m from 1%-100%
* no internet speed indicator at status bar, need to download app to display it
* some samsung bloatwares.. sigh
