I'm using Samsung galaxy m21 bought on 2020 . After the Warranty period was dead (means exactly after 19 months from the date of purchase) the phone starts to hang and repeated restarts abnormally. I've heard that most devices with this Exynos 9611 chipset ( like M31, M31S, A51 etc) has the same issues...at service center they suggest to replace the entire motherboard which costs around 6 to 8 thousand. Is there any possibility to resolve this problem?.. kindly help with your suggestions and ideas...Thank you guys.
