Sure- here are some examples. I carry a Pixel 6 pro max and it is a steaming pile of *sugar*. It drops signal and I have to restart to get it back, it refuses to send txts and I have to restart to send or receive. Plenty of others on forums have the same issue, and Google does not care of fix. Additionally the battery life has now gone south as well with it tapped out at 8 hours of light use.
I have a Samsung tab- most laggy and unreliable thing I could use. youtube (another google property) randomly fails, will not restart and I have to restart the tab to get it back.
ALL of my NEST products that Google purchased are hot garbage- my nest doorbell (I purchased after google aquired) has peeled and yellowed and looks like crap. Anytime anyone pushes the doorbell it cuts the video feed, nice feature (started in the last year). All my Nest Hubs have started acting strange- ones in farthest away rooms respond when they should not, adjusting sensitivity makes it worse and not better. They also lose all ability to work on a bi-annual basis and I have to wipe and re-add them to the network (which takes 3 tries with google home because it fails constantly). Google wifi sucks, it does not cover like it should and requires a network reboot on a regular basis to get the speed back.
Chromecast sucks because it now needs to be turned on and does not auto-sense the HDMI port being active like it used to, it also is slow and loses connection regularly.
(I have tried other wifi and it does not help these other devices, I have totally changed out wifi with no help either).
All google devices RANDOMLY decide to forget my voice print and refuse to work for me on some days, then others they do. Google will drop services like spotify or Iheartradio on a frequent basis, making them not work correctly some days and then fine on other days.
Would you like more examples? Do you go as deep into the ecosystem with better results?
