My Roku 4 tonight suddenly only shows the initial ROKU splash screen on the TV but never gets to the Home screen. I have powered it off and on several times with the same result. Anything I can try? Is it dead?
It worked! Thanks so much. I did not put the card back in yet. I got periodic notifications that something would be improved with the micro SD card inserted. So I put one in a month ago. But I can't tell any difference in performance. What is it supposed to do?
As a detail: the SD card does nothing for overall Roku performance. Because it increases channel storage space, if you have a number of channels it might improve the channel loading speed. But only if it's a channel that hasn't been used for a while and Roku had offloaded the channel for a more heavily used channel. The Roku 4 (4400) had 1.5 GB of memory storage, at the time the most of any Roku player. So unless you have a large number of channels and regularly use them all, the SD card is of little value. I have never used on on any of my Roku devices, and I have I believe about 55 channels installed. And I use maybe 4 of them on a regular basis.

According to the Wikipedia article, the Roku 4 has 512M for channel storage. The 1.5G is system memory. For reference, older Express models are typically 256M, Premier's and newer Express have 512M, and older Ultra's 1G. It looks like the latest models (3940, 3941, 4800) have 4G. The Streambar is only 512M.
