I don't know who to contact about this... I have virtually a brand new Samsung phone ... and I have a strict rule not to accept updates for personal reasons I won't make public yet .... I accidentally installed an update last week and like i presumed my newish phone from the moment the update was finished my phone has gone rubbish 🗑 from the very minute my phone was updated its gone downhill... how can this be?sometimes I can't even access my phone without switching it on and of and restarting
