Solved: Note 9 Back Cover Cracks

Ronny Carol · ‎26-01-2021

I've had my Note 9 about a year and a half. I have had to replace the back cover 3 times, now.

It will show grazing, and then will crack. This is always where the battery is located.

I have a case and screen protector, always. It is not impact related.

It is because if the heat generated.

Has anyone else had this issue?

Tom, I think I figrured out what was causing the grazing/cracking of my back cover.

I think the battery was seated incorrectly.

I bought a new battery that actually turned out to be a bad battery. But, after putting the old one back in, I am not seeing any grazing.

So, it wasn't a faulty battery, but that fact that the original battery just wasn't in there correctly, and that bottom part was too close to the cover.

Aydoeji, my back cover kept grazing, then, cracking in the lower half. It turned out the factory installed battery was not seated correctly.

I just had to undo the whole back, take the battery out. Then, put it all back together.

To date, I have not had ANY grazing, nor cracking.

Did you buy the phone brand new from samsung?

I had a Note 9 from August 2018 till the end of 2020 and never had this issue even though my phone would get hot when doing intensive tasks like gaming.

New, but not from Samsung. I am thinking my habit of using my phone while it's charging might be the issue.

I guess I will just resign to changing out the back cover. I'm getting quite good at it.

Did you have your phone charging at the same time? I do, and I think that may be the issue.

yeah I wouldn't advise that on any phone... especially with smart phones these days... its overwhelming the battery. I've set mine so that it reboots once a week for a refresh.

Hey there Ronny Carol!

If the phone's grazing where the battery is, could I suggest that you maybe replace the battery on your handset?

Sounds like your battery may be expanding which is pushing/breaking the glass off of your handset.

Batterys can be obtained pretty easily, or you can book your phone in for a Samsung doorstep repair for around £59.

Hope this helps,
Tom 🙂

nope I have never used any of my phones while they are charging

The person you bought it from may have changed the battery to a non samsung battery which may be unsuitable for the phone which could be the reason it is getting hot and cracking.

Hi, Tom. Thanks for your input.

The grazing happens right under the Galaxy Note 9 logo. The cracks radiate from the grazing, downward into a Y to the left corner.

There no bulging, though.

What do you think that might be?
