Because nothing compares to it really. The polish, the UI, the UX, plus the developer ljdawson is an awesome bloke who listens to his users, as he's shown time and again. So, I'm happy to support a dev like that.
I don't. In fact, I don't send birthday wishes to anyone unless they're really close family/friends. Otherwise it just seems fake, there's no point wishing someone if it doesn't come from your heart.
Pretty much most manhua/manhwa. There's sadly no manhua/manhwa community here.
eBay is fine. Just check the seller's reputation first before buying.
If overall positive feedback is greater than 99%, and they've sold hundreds of items, then there's no problem buying from them.
I've bought dozens of phones from eBay over the last two decades, never had any issues.
By checking whether the bootloader is unlocked or not. If the bootloader is unlocked, then all bets are off, but if the bootloader is locked, you can only run the original, unmodified firmware. Any alternation to the firmware will result in the dm-verity check failing, causing the system to not boot at all. The only data which can be altered is user data, which is wiped in a factory reset. So a factory ressr definitely gets rid of it.
If you're paranoid though, you could always flash the stock firmware downloaded directly from the manufacturer's website, which will override all system partitions, so you can be absolutely sure there's no spyware - besides the spyware included by Google etc of course, or the spyware embedded into the hardware by the chip manufacturers...
Swappa is US-only, it seems that you're in the UK so forget about Swappa.
And rooting the phone requires an unlocked bootloader, which would present a warning when the phone is booted up.
