Oh Ouch! Yes I heard someone had story their cellphone blew it up like that.. Due some defective recharged batteries blew cellphone out and harm the owner. I forget what brand of cellphone name. like start with "N"okia, (is that correct)?
Did you know that battery in cellphone could be bomb as blow up and harm you.., Because recharged battery or cellphone is either DEFECTIVE which can cause like that.
It looks like a old Nokia Cellphone to me
