Today I have just visited Samsung service centre to inspect my M30s mobile which is continuously freeze and restarting. And believe me, those service centre guys literally said ALL M SERIES PHONES ARE **bleep** without any hesitation. After some usage period you will definitely encounter some problems in this series. Those guys showed me bunch of mostly M SERIES phones particularly M30S mobiles for Motherboard replacement.There r bunch of victims same as me. I was stunned. I have already written an article on this, so I don't want to discuss more about Motherboard, Freezing and restarting all.
So what basically Samsung doing is they are using some cheap quality and faulty Motherboard for M SERIES which DOESN'T LAST LONG. Those guys said there is only one solution for Freezing and restarting that is Motherboard replacement which cost ₹5000. Its been only 15 months since i bought this m30s. I am not able to go for it after I encounter that bunch of Motherboard failure phones. So absolutely its not users fault. They told me to go for other Samsung phones except M SERIES next time in future. And I am not going for that either.
So its better to avoid M SERIES is you have a plan to buy. DON'T WASTE MONEY. YOU MAY ENCOUNTER PROBLEMS IN FUTURE if u do so. Crappy Samsung.
Thanks for reading....
The fact is, if you look up this particular forum, you will find many many A series users( mostly A50, A50s, A51) are having the same freezing and restarting problem. So how does that logic of using "cheap motherboard for M series" holds up? I don't understand. If you notice, 99.999% of these problems happened with phones that came with the Exynos 9611 SoC, regardless of their series(A orM). Yes, its true that the most number of affected models are M30s, but the A series is not outside of this problem either.
If you plan going for Samsung device opt for the ones having snapdragon chip, as the exynos chip after some time end up showing the problems u above mentioned
