Periodic corruptions, BLE failing? [fixed]

Hi, sorry you've had so many issues. I'm pretty hopeful this isn't a storage issue though - generally if something really bad happens when you restart your Bangle it actually pops up a menu saying "Storage Corrupted" and puts you into the recovery mode - luckily this is very rare now!

I can't really comment on the Working Memory app, but it wouldn't surprise me if some of the apps on the app store do occasionally behave a bit strangely. But if you can figure out how to reproduce it, it'd be great if you could file a bug report so it can be fixed.

I'm not sure what the top "TS" item is

It's touchscreen. It'll be red until you tap the screen and it registers a tap in the correct area :)

Some sort of corruption where I needed to reset the bootloader

Were you playing around developing things with the Web IDE? Especially if you've been using other Espruino devices you may well have had it set to Flash, which overwrites the bootloader. We do mention this a bit in the getting started guides but it can be quite easy to miss, especially if you've used the IDE before.

factory reset but not communicating and displaying "-> Bluetooth" when it boots

Exactly as @fanoush says. Far from Bluetooth not working, this is almost certainly because one of your devices is automatically connecting to the Bangle, and since it can only have one Bluetooth connection active it's stopping the others from connecting.

Best bet is go outside away from your PCs/Laptops and just try and connect with your phone. If you can't connect, try going into your phone's OS Bluetooth settings and see if it's listed there, and if so forget it.

But most likely it's a PC/Laptop you have at home that's ended up with Bangle.js paired in the OS menu for some reason, so it's trying to automatically connect any time it sees it.
