Recently upgraded from an older Samsung to an S24. Very disappointed to find that it charges just as slowly as my old one! What happened to fast charging? Also signal with 02 is rubbish, but on old phone (A20e) never had one problem with signal. So, sadly, seems like an expensive and backward step. I will probably refer back to John Lewis to see if their techies can help, but will probably have to return it if can't be resolved. Shame, as it's a nice phone, but charging and phone calls are kind of key! (I'm in UK).
