Hello. It would be better to desolder the IC and solder it back.

@tomasitasovc9372 i know it's always better, but lets say phone was and will be totally abused by owner, would a good reflow be enough? Just to make solder balls do their thing again?

​@@lordmmx1303 You can try just resoldering, maybe it will be fine.
