I have an S22 Ultra
End of Oct it turned off whilst wireless charging in the car, then went in to a boot loop
I tried the advice of putting it in the freezer which did let me clear the cache but I took well over 100 more hard reset attempts to be able to wipe the phone
With the phoen wipes it carried on boot looping, progressing to the welcome screen, shutting down and going again.
Having looked online and found a sea of users having the same problem, it was clear one UI was to blame.
I believe that power users are hit, as the motherboard gets cooked, mine is in the car on wireless charge, running an android auto app and providing a hotspot to the Tesla, for a 70 mile each way journey, it's been fine till they updated me.
I was in warranty and reached out to technical who are a joke, I spent 2 months trying to get the phoen sorted and when it finally hit her repair company who are a contracted agent in the UK then started another 2 weeks of them trying to change as by then the warrenry had expired.
I got extremely frustrated, with technicals low English and terrible response times not going it get sorted, I had to evidence everything, corrispondemce, proof of purchase etc to the management of the repair company.
Having returned a multip thousand pounds 65" Samsung OLED did to faults and also returning a £1500 sound bar as the rears kept disconnecting and it kept falling over attempting Atmos, combined with a mid range Samsung sound bar calling out lihdly and randomly "Network disconnected" which research shows to be another known fault, this will be my last Samsung product, they are market leading but the warrenry, support and product reliability is pathetic.
Amazingly as a cover phone I used an old note 9 (the note 10 I had also went faulty) and it was great, it's smaller, lighter, apps work with the same pace, the very annoying WiFi to car constantly dropping on the S22 Ultra or refusing to connect at all was not a thing on my Note 9, in fact the other things that are better are display and camera and i'm not overly sure the extra weight and thickness are worth it.
I'll use this tell it does, then I imagine I'll move to Google, I know it's not as top end but they are all capable of doing what we need now and I'll favour reliability and some customer support ongoing.
