Hi boring, We appreciate your feedback on the remote, as well as the buffering you're experiencing. Buffering when streaming content online is related to your internet connection speed. Buffering may occur on your Samsung Smart TV while streaming video content over the internet. Buffering usually occurs when your internet connection provided by your ISP cannot supply data fast enough for the playback device. We suggest you try the following: 1) Use 5G Wi-Fi if possible 2) Try wired LAN if available 3) Try repositioning the router so there are no obstacles between your TV and the router 4) Please be sure you have the latest firmware update which enhances network connectivity. Should your issue persist, you may want to contact your ISP to check or increase your internet speed.

Hi Juanma! Thank you for choosing the 2021 AU8000 Crystal UHD TV and for your review. There are several volume features you can enable/disable/adjust to your liking. 1) Auto Volume automatically adjusts the sound to a certain level when changing channels or switching to another external input. 2) Adaptive Volume automatically adjusts to a specific volume level while you are watching TV. The TV analyzes your volume usage history by time period to automatically adjust the volume when you use an app or switch to an external input source. 3) Several Sound Modes are likewise available to meet your personal preferences: Home > Settings > Sound > Sound Mode Also, some sources have their own volume control which might be set too low. Please check the volume control of the external device (cable box or satellite box, DVD, Blu-ray, etc.) connected to your TV. Also, check the cable connection between an external device and the TV and then try cable connection again. Should you ever have questions or need help, please call us at: 1-800-SAMSUNG (ask for TVs), available 8AM -12AM EST M-F (9AM – 6PM EST Sat). Or text HELP to 62913.
