I suppose if it was a hard enough drop. Maybe. Trouble is the electronics are very sensitive, and maybe the screen part under the glass could have done something to those electronics. I've seen oled panels when they get damaged arc. Could easily damage PCB electronics. Also not being careful when doing a repair will obviously damage something. No way to prove one way or the other to be honest. Just annoyingly expensive as I found out when the screen got damaged on my one month old Note 20 Ultra😒
Thanks for the reply. The fall was onto a rug but the bounce took it into something hard. He's wanting to charge me £199 for the screen plus £30 for the motherboard, which I feel is reasonable. Do I need to be cautious about having both changed?
Isn't it always the way. Be the one hard surface they hit 🙄 Don't think there will be any issues. I think £30 is a bargain. Must be a reduced cost as they have it there and it's stopped working after the screen replacement. Sure they are somewhat more expensive normally. Maybe because it's considered an older device
Hang on, this red ring issue. I've seen this issue on YouTube before - there's a guy called Hugh Jefferys who salvages quite a lot of phones.
Anyways, ever since the Note7 issues, Samsung's phones have an array of temperature sensors in the Wireless Charging Module.
This might seem completely irrelevant, however, without that wireless charging module attached, your phone won't charge and you'll get the red ring you're mentioning here, along with a thermometer icon (and a red blinking LED indicator, if your phone's got a notification light).
Try asking a shop to fit a new wireless charging coil first, doesn't really sound like a motherboard issue 😀.
