As good as Roku TVs are, they unfortunately don't have a borwser option. If you really need a solution, the best option is to use your android device or your laptop for streaming.
You just have to follow a few simple steps. First, open the app on your device that supports Easy Pair. Then, follow the given instructions on the screen to generate your special code. Once you have it, find your Easy Pair app on your TV, and enter the 7 digit code shown on the screen of your chosen device. You'll soon receive a confirmation message.
Unfortunately, you can't move the clock on your lock screen. You can only change the display of the clock. For that, go to Settings - General - Date and Time. Here you can choose the form you like the most.
No, you can't. Though it might be disappointing for you at first, this is actually a good thing as it makes Roku TV surprisingly safe. You can't jailbreak a Roku TV simply because it uses its own operating system that is closed, and only accessible by certain Roku developers.
Unfortunately, you can't. If your AirPods are paired do your phone and they are within Bluetooth range, you can use Find My Phone to track them. That's the only option, the serial number alone won't help you.
