Beware of auto-sleep cases for Tab S3

[zugok]

I have discovered that the Samsung Tab S3 is very sensitive the magnets on the third party (not Samsung) cases, and have caused dead spots on a S3 that I then had to exchange for a new one. I have also read posts of the auto sleep getting messed up too.

You can test this by using the pen with a high level of pressure sensitivity, areas affected by magnets become much less sensitive or require greater force than the surrounding are to get a similar brush stroke.

In the video I am using Infinite Painter, but similar tests can be done in other apps.

Yes, it is bad news. I've read this in several reviews of different magnetic lock cases on Amazon, and seen a few photos of dead spots in drawings.

But the Samsung case gets poor reviews because it didn't stay shut and because the tablet is not held in very securely. The keyboard case doesn't let you also use the camera, though as it only just grabs hold of the tablet, I don't suppose it matters.
What bugs me about the Samsung cases is that they don't have anywhere to hold the s pen! The best they can do is a stick on loop that looks as if it could come of easily.

I have an old Asus Nexus tablet from years ago (still works) but my friend used a third party case on it, caused yellow discolouration of the screen around the edges (magnetic flap - not even directly connected to the screen).

Well, as demonstrated here, magnets still screw with electronics (the stronger the magnet, the worse it is); I don't use magnetic cases of any sort for this reason (even if it's light/sensor only) -- also Murphy's law says my cards will probably pass it at some point and will eventually need new ones too :laugh:.

ETA: It would be easier to see some sort of X-Y position overlay with pressure detection (is there a setting in Developer Options to enable such thing?). Perhaps the device itself is defective? At least warranty should cover that.

Tried 3 cases with covers, now using https://www.amazon.com/gp/product/B06XWGPP3H/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 .

That looks interesting but it doesn't appear to have an S pen holder.

Wow... This would totally explain why the *really* expensive official keyboard cover does not cause the tablet to auto-sleep/auto-wake. I feel a lot better about it not having that feature now, actually.

I bought the "Tab S3 9.7 case, KuGi Tab S3 9.7 SM-T820 / T825 case - High quality ultra-thin Smart Cover Case for Samsung Galaxy Tab S3 9.7 inch tablet.(Black)" cause some people here said that it didnt auto wake tablet but it also wouldn't mess with spen.

They fix the auto wake problem and at the same time they mess with spen causing the known problem showed on video. Beware of that case. I bought from amazon uk, they will refund me, i only had it on my tablet for five minutes i hope my tablet is ok!

Can you guys please recommend a protective folio case WITHOUT magnets?

I wish I found about this thread a week ago, before buying a cheap one. I was trying out the S Pen when I spotted some places with lower or zero sensitivity while drawing. I thought it was the tempered glass at first, but as I took off the cover, everything worked smoothly. I won't put it back on until I find a good replacement without magnets. Can I get some help? :fingers-crossed:

EDIT: What about this? A comment in my language marks the lack of the sleep/wake feature in cons (which translates to pros). Do you know the KuGi UK brand?

I will surely recommend the MoKo Galaxy Tab S3 9.7 Slim-Fit Multi-angle Folio Cover Case. I had bought other cases earlier and just wasted my money as there magnets affected the SPEN drawings. Moko one is perfect for me now.

i don't know why you have problem but my magnetic case works perfectly since i bought the tablet last month.. i bought this one: https://www.amazon.de/gp/product/B01D64K8L2/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

Magnetic Case

will a magnetic case really destroy the digitizer? or can we maybe remove the magnet? my magnet is only on the left side of the tab.

I looked this up on Amazon and it talks about auto-wake and magnets. Your's does not have magnets?

Has anyone tried the poetic cases? They have magnets but this seems to be a fairly popular brand. I might have to dig into it and remove the magnets if not xD

If anyone is interested in knowing , this case has 5 magnets and I removed them all. If you're interested in knowing their locations hit me up and I'll be more than happy to share.

Hi All,
Exactly the same problem here, even with the flap folded round the back ready for use, this is enough to make the pen very unresponsive, let the flap hang down and pen works perfectly, perhaps the metal strip in the flap gets magnetised due to constantly touching the magnets,
I have now ordered this case from Amazon UK, along with a couple of stick on stylus holders, I will attach these inside the back cover of the case then fit the tablet in:
KuGi Galaxy Tab S3 9.7 case ,Ultra Lightweight Semi-transparent Smart Cover Case for Samsung Galaxy Tab S3 9.7-Inch Tablet w/ S Pen SM-T820 / T825 (Black)

For those of you that did have issues with the sensitivity, does it do permanent damage or will removing the magnet help resolve this issue? I noticed this the other day and returning the device is going to be next to impossible considering my deployment schedule. Or does anyone have a fix for this without a replacement device?

The magnets were rightly placed so no issue with Spen and drawing apps.

 

[jimbus80]

What about the "ProCase"?

 

[Eggstones]

Sorry but I'm not sure what the issue is. Does magnetic cases actually destroy the screen or is it just interfering with the usage of the pen?

 

[jsalatas]

Hmmmm.... I'm having a similar issue as you can see in the following video
https://youtu.be/kaPxqq5Aqn0
However I'm not using any third party cases. I'm just using samsung's keyboard case.

I bought my tablet at November 12 (less than a month) and I just created a service request. I'll keep you posted on any news.

In my case it is permanent
