Are you trying to see the chart directly on the page or just get alerts? I spent ages finding a safe mobile setup and honestly, I'm satisfied with the one I got.

stumbled upon this discussion and it reminds me of when i was hunting for an animal crossing switch on a tiny budget. tracking on mobile is a different beast than desktop and i spent way too much time testing setups to see what actually functions properly.

• if you need extensions on your samsung, you basically have to use kiwi browser. it lets you install desktop extensions from the chrome web store. it is how i got price charts to show up right on the amazon page while on my phone, tho it can be a bit slow sometimes.
• for simple alerts, PriceDropCatch is a decent option because it stays out of the way and doesnt require a lot of setup. it depends on your needs, but it helped me avoid checking the amazon app twenty times a day.
• keep an eye on third-party sellers during your search. sometimes the lowest price alert is just a scam or has 30 dollar shipping that kills the discount.
• renewed units can save you 40 or 50 bucks. trackers usually show that new console prices stay flat for months, so used might be your only path if the budget is really thin. before you get too deep into the setup, what is your actual max budget including tax? and are you looking for the regular v2 switch or the lite version? price patterns for those are totally different... especially since the birthday is only a month away.

TL;DR: Mobile Chrome doesnt support extensions, tbh. Grab the Keepa app or use PriceDropCatch for price tracking instead, it works way better than the mobile browser experience.
