I bought a new S24 ultra at the end of June last year. After a week or so the camera app failed so I restarted the phone and the camera app then worked ok. I thought I must be doing something wrong. Anyway, the camera app froze at random intervals. From my own experience in systems programming I concluded that it was probably a sparsely defective RAM. I recorded intervals from 7 to 150+ hours. Later observations saw the phone heating up and then shutting itself down and restarting when the internal temperature had dropped.
I sent the camera back for repair 3 or four times. On one occasion I was told the camera had been repaired when it obviously had not. On other occasions it seems that the Samsung diagnostic system could not replicate the fault and the phone was returned, almost by return post.
Now, I had sent screen recordings and shots of the fault occurring and spent days on chat and phone with Samsung reps, all of whom seemed to be reading from some kind of script and asking me to do different things, which I did. The ***** thing failed in SAFE mode.
I was fed some ridiculous story of why the phone would get hot - 'shortage of RAM'! - I had 512 gb and very few apps, certainly no games.
I believe that Samsung's policy is to kick the can down the road and actually show NO support. The chat stuff was a kind of sealioning.
Eventually I had had enough and contacted my credit card company and explained the situation. They were more than willing to take action and then I realised that the purchase was from Amazon.
I contacted Amazon and after explaining the same to them they asked me to send it back, which I did. A refund has now been issued..
