Mobile phones I had owned in the past:

Nexus 4

4/5

Great in most ways, the only problem it had is the lack of support for external memory.

Moto G2

4/5

Greats in most ways, but slightly underpowered and no notification led.

Moto G3

2/5

The screen was unresponsive and slightly less performant than the G2.

LG G4

3/5

Is a phone with great specs that allowed external memory and removable battery. It was plaged with hardware defects that reduced the expected. They also had a forced LG theme/apps that reduce perfomance.
