[AT&T Samsung Galaxy S 5] TQWorld:
Hey all,

I ran into an issue with this message and was able to resolve it. My round-about story (with all the details, some immaterial to the issue)...

The issue: Anytime the phone would be accessed/woken up after a few minutes of not being used, I would get the message to check the battery cover. I also would get the message when rebooting but that one appears to be normal. The one that appears each time after minutes of inactivity is not normal. I would only get the message to check the charging port cover after removing the charging cable, so that always remained normal and as it should.

I did the usual: ensured that the battery cover was on correctly, securely and entirely...several times. I figured it was an issue that I was going to have to live with. I also noticed that I would intermittently get a message about my SD card. Sometimes the error would say that it is blank, sometimes it would say it is blank or has unsupported files on it, other times it would simply tell me it was safe to remove my SD card. All for no apparent reason. I placed my card in my daughter's S5 and it worked. Placed it in my wife's S5 and it worked. Checked it on my PC and it worked. I even went so far as to wipe it out, format it and try again. Still received the error message on my phone. Not frequently but often enough to where I began to wonder if I was sold a bad phone.

I read some folks recommended doing a factory reset. I had nothing to lose so I did. I was reinstalling everything and things went well for the first few minutes and then the screen died. The phone was live, the buttons would light up but the screen would never turn on. I immediately headed over to the store and spoke with a really cool manager would agreed to swap out the phone for a new one since I have only had it 3 weeks (as opposed to sending me to the circus tent that is the maintenance facility). New SIM, new phone. Was a happy camper.

Got home, installed everything...and again....the messages started coming to check the battery cover. Frustrated I just decided that it was an issue I was going to have to live with afterall. Hopefully a fix will come about later, right? Well, it wasn't too much longer that the SD errors started again but this time more often. This can't be good. So, I decided to try swapping out the SD cards on my phone and my daughter's phone for a longer period of time. Let's do it overnight. So, in the morning I checked my phone (with her SD card). No messages at all. I checked her phone with my SD card. Hers now had the check batter cover message. I let both sit for a few minutes and checked them again. No messages on mine, but hers once again had the check battery cover. No errors regarding the SD card tho and it was able to access the content on the SD card just fine. Both SD Cards are 16GB SanDisk.

So, to further test, I swapped the SD cards again, putting her card back in her phone and mine back in my phone. Sure enough, mine was getting the check battery cover and hers was not.

So, long story short, it turns out that my SD card is causing the check battery message. It was throwing SD card errors on my phone but not on hers. So, for those people getting the constant battery cover message but not getting the SD card errors....try swapping out SD cards and see if that resolves the issue.

Hope that helps and wasn't too wordy...just wanted to make sure all the info was there.

EDIT:

SD Card that went bad was SanDisk microSD 16GB. Was replaced with an identical card and works fine. It has been a couple of weeks now and the replacement SD card in my GS5 continues to function properly and I no longer get the pop-ups unless I reboot or have actually removed the battery cover. I left the bad one in my tablet this whole time just to see and sure enough it was giving errors for a week and now it simply no longer works.
