Imho I think there should be almost no problem of laggy navigation or scrolling while navigating through the homes or a list considering the reviews says "The system performance is not only high subjectively, but almost approaches the level of a Snapdragon 630 in the PCMark." and the youtube videos in wich it seems there is almost no delay in inputting commands be they ui navigation, application opening etc.. But may i ask to the reviewer if they can use that software that displays the number of dropped frames while scrolling a list to evaluate the smoothness of the device? Because it seems what Nicolas says (input lag, stuttering) was the biggest faults of Moto G4 and they were very unpleasant considering moto g3 was very good in this regard.

What about general performance? Any noticeable lag while using the OS? Does it has input lag or stuttering?

There is no problem with the vibration motor in Moto's G6.

It is pointless to compare any phone to Moto G5S. The G5S phone is completely useless because its vibration motor is louder than its speaker in high volume. Motorola support has also verified that. The author fails to mention whether Moto G6 has the same problem or not. I am surprised that there is no comment about this anywhere in the article. Maybe this was done deliberately?
