I know that they are considered legit company but after long waiting i receive my ledger nano s and it doesn't work
tried all the troubleshooting guides on their sites (delete other apps, reinstall chrome etc)
nothing worked out.
im pretty frustrated from this and from contact support.
i read that its most probably problm with cable, so why they are providing cheap cables from the beggining ?

Got mine directly from them and your problem is very easy. You can just try it out with other cables where you can see it through android phones as their chargers.
This isn't a big problem to deal with. How come that you have tried "all" troubleshooting guides, just change the cable - look for another one and it will be fine and your device will be powered up.
You shouldn't be upset with these such basic problems that others are dealing up with it early and solving it easily just because of the cable.
