This is the third Chromebook that I have purchased. My first was a refurbished one that I needed in an emergency that only lasted 3 months. My second was a previous Samsung model and it lasted me about 2.5-3 years.I have the same issues with this Chromebook as I do my last Samsung one:1- The audio jack: the audio is incredibly static-y when using normal headphones. When using headphones I pretty much have to find some sort of white noise to play in the background to coverup the static, or use a bluetooth headset. It's incredibly aggravating at times.2- The screen. I'm not sure if it's the way I store it in my bag or what, when the Chromebook is closed, it makes contact with the keyboard, and needs frequent cleanings. I'm not sure if it's that the back cover is too soft and pliable or what, but this is a common issue. Now, when I go to clean the screen, no matter how gentle I am, it's inevitable that I will get damages pixels in the screen. I replaced the screen in my previous Samsung Chromebook twice in the 2.5-3 years that I had it for, and on this one I can already see some spots that are becoming damaged.I was hoping with this later model that some of these issues would be improved on, but It doesn't look like it.For anyone who has a Chromebook, I would also recommend getting rid of the ChromeOS and making the switch to Linux's GalliumOS. It's definitely worth it, and will put that hardware to better use.
