Is there any sign before a battery explode?

'counterfeit' batteries have become far less common since batteries are now sealed. Back in the removable battery days, tons of third-party batteries, including dodgy ones, existed. Often it bit those who kept their devices long-term, and the OEM supply had long since run out.
That said, it won't be sudden most of the time. Leaving your phone on charge long-term can cause it, and it shows itself today by being so slightly bulged that you wouldn't notice it until your phone becomes a sort of fidget spinner because it's no longer level on the table. However, the Note 7 was a thing. Those phones, sealed batteries and all, were instantly cremating themselves despite two recalls later. Enough that Samsung issued a software update first to limit charge to 65%, then later to disable the ability to charge, essentially killing the model that way.
The only time a Li-Ion battery does instant fire is when they have a dead short inside them. You'll be aware when the phone gets so suddenly hot that it's burning you somehow. Li-ion fires/shorts are not as common as they used to be, but occasionally happen, much to the dismay of a certain few Tesla owners.
