I APOLOGIZE IN ADVANCE FOR SUCH A LONG POST. I have searched for an answer to this question and I apologize in advance if I am reasking the same question. I have a problem with my N1 freezing up. It happens a couple of minutes after I turn on the phone. The phone just freezes and won't respond at all. I have contacted HTC. I have swapped out the phone twice (this is my third phone). It keeps happening. I think I have narrowed it down to a problem with the memory card reader. I have bought three separate 8Gb cards two from Sandisk and one from Kingston. It doesn't matter it still happens. Just sometimes when I switch cards it won't happen for a couple of days. I should mention that I formatted all of my cards with FAT32 in windows and I formatted them using the phone also. I ran CHKDSK on all of them and although there were errors on one card it even happens with cards that CHKDSK says are fine. I even used a 2Gb card and the phone froze up then too. I am at a loss as what to do next and I am tired of playing musical micro memory cards. P.S. the phone does NOT freeze up when I DO NOT use an SD card at all. (BTW I also think HTC sent me one of those N1s with the SLCD screen...) Thank you for your help. (Moderators please be kind enough to move this if I have posted in an incorrect place. Thank you)

I finally figured out what was causing the problem. The CNet Audio by Mediafly app when stored on the SDCard was somehow causing the phone to freeze. It sounds ridiculous but after exhaustive troubleshooting with every variable that seems to be it. If this info helps anyone...If not and a mod would like to trash this post. Please do what you would like. Thank you.

Looks like your sd card is beginning to wear out. Better backup as much as possible and replace it right away. I once had 2 kingston cards with similar issues. Formatting them seems to fix it for a short period of time only. Then eventually the problem returns.
Did you try erasing the card through the phone itself - that is putting it back again after un-mounting from your PC?

i would like to know if Ia m the only one, experiencing constant restarts on the phone,almost every single day and more than once.
hmm sounds like you have some sort of software issue, reflash the software and see if you get this issue again. I've had the phone 2 weeks now and had no weird restarts or anomalies, check my sig it shows what firmware on.

Your sig is what I have really surprised, o well might do a reflash or something, but the phone has also shut off a couple of times, not sure why, but when I unplug the phone from the charger usually.

Yeah I will let you know, besides that, this phone is great, build quality, UI, battery, display, and even the speakers are louder than the G2 and yes I compared them. This is by far the best android experience I had even if it restarted, it is still the best I owned

Well I thought I was the only one, but it seems in android central people are reporting random shutdowns, please let me know if this is a widespread issue, because they also said they dont have an SD card to wipe, so it seems it's not the card causing the problem, but certaintly the same thing is happening to me.
I having these issues also, i have left a message on sony facebook page. This is starting to piss me off for a $1000 phone it is not good enough. It is also corrupting my files on the phone
Wow that is definitely not acceptable, Im leaning to switch back to the HTC One, but still debating, depends to see how many are having this issue.
if anybody knows let me know if this a known issue or if is affecting only a small portion of the phones thanks

HERE YOU GO MY FRND
All users who are facing this problem... i have solved it.. the prob is with android 4.0+ onwards... do not pop in mem cards from other fone directly...
take your memory card out and copy the entire card data on hard drive and then format the card in pc with default settings. then switchoff the fone and put the card in it... it will take smtime to initialize the card at first run. have patience and let it create the suitable folders... the data u looking forward to copy is pics, vids and music files... rest stuff is there on ur fone and it will stop rebooting. DO NOT FORMAT THE CARD FROM WITHIN THE FONE... it has been seen that with android 4.0+ they do not format flawlessly....enjoy and ur rebooting problem will b over...
I have the same problem. My Z1 restarts several times a day. 10 times just today.
I don't have a sd card in the phone, and I never had any sd card. So that can't be my problem.
I don't see any pattern in when it restarts. I can be browsing the web, checking facebook, playing games. Or when the phone just lays on the table. Charging or not charging.
One thing I have seen is that right before it restart the cell signal is gone and there is a sim card icon in the notification bar.
I'm switching cell provider in 2 days, so I will see if it gets any better with a new sim card.

well that doesnt seem a solution for me, I tried what he said and didnt fix my problem the shutdowns happen quite often, I might have to look at a stable device, I may look at the incoming nexus 5, I do like the Timescape UI, but restarting a couple of times a day I cannot agree to that, I had it happen when a call comes in, so it is a problem, because people think I hang up on them.
I got my new sim card and the phone haven't restarted once!
So it looks like my problem is solved.
The difference between my old and new provider is that my old (OneCall in Norway) is renting net from Telenor and the phone is roaming most of the time.
My new provider (Netcom) has its on cell phone net.
If you have the same problem you could try with a new sim card, or use the phone without a sim card for a day.
I've this problem too. I don't have an sd card in my phone and I didn't move any old files from another phone. I've been getting a random reboots per day in the last 3 days. I love this phone but I'm not sure if I need to return it. It is unacceptable.
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.

Damn I was hoping for something different. I'm getting the same messages,
But I haven't put a SD CARD in yet. Still have my Note 2 running, S5 is a work phone. I've tried different ways to install cover. Mostly following the pressure point indications that flash up with the message pops up.
I'll monitor it, I can't remember when the last time I've seen them. Forgot phone at work yesterday charging it.
If I don't get messages any more, my fix was putting the cover on starting at the top. You definitely need to hear the clicks on all sides. I noticed sometimes I would not hear the top click if I started putting cover on from the bottom or sides.
Good find on the SDCARD issue though. Can you edit your first post and add in make/model of the cards that are working for you, and the one that is causing errors as reference.
It would be interesting to know if it's specific makes/models/sizes of cards that cause the message.

Actually, you were treating the symptom, not the cause. That's the same as if your car was leaking oil in the driveway and you simply put a pan under the car to catch the oil. Sure, you are no longer getting oil on your driveway but it doesn't change the fact that your car still has an oil leak and will eventually lock up the engine if not fixed. By fixing the actual problem (bad SD card), I was able to resolve the pop-up notices.
Fix the problem and the symptoms go away.

When everything is working properly do you get the "check battery" pop up after reboot and "check charging flap" after charging? YES it's built in annoying I was offerin a suggestion to get rid of those annoying pop ups that is all.

Yes, the message does now appear only when it is supposed to and no longer appears when it is not supposed to. When it appears as designed, it is not a problem. It may an annoyance to some, but is in no way a problem because that's what it was designed to do. When the pop-ups do appear at times when it is not supposed to then it is considered a problem because that isn't what it was designed to do. Mine was doing it when it wasn't supposed to. This is why the title of the post was called "Check Battery Cover message problem" and not "Check Battery Cover message toggle to shut it off from showing up when it's supposed to."

Wow that's a trip. I was expecting it to be an issue with maybe the top of the card being slighter fatter.
I was beginning to question whether the I-Balson case I put on it was tripping a sensor.

Slightly bend connectors - Samsung S5 - check batteri message
Hi!
I´ve also had the same issue for some time and it started when I got a new flip wallet case. Now I got real tired of this and I tried to solve the issue by simply and carefully BEND the two connectors on the back of the phone nearby the camera. And that SOLVED my issue - the message is gone!! Before it came frequently all the time. :good:

I know this is an old thread, but oh man! is this guy for real? can't tell if it's a poor attempt at trolling, or a poor attempt at issue comprehension and resolution.
Old thread but I just got bit in the butt by this one. I was only getting the message about the back cover on reboots. I would have thought that you would never see this message unless there was an issue, but did some reading and it seemed that this was normal behavior. So I took the phone snorkling (yes I know you're not supposed to take it in salt water but figured I could clean out the headphone jack). By the time I took it out of my pocket to take pics, it was dead (no more than 5 minutes). Took off the back cover, found water which left salt behind after it dried. Phone has not recovered, I am going to try to take it apart this weekend and clean out the salt. It was a work phone and already been replaced, but I'd like to try to get the pictures off of this from my vacation. It would be nice if there was a way to know for sure if the phone is properly sealed up before going into the water with it. Work gave me another S5, but I won't be exposing it to any water because I can't trust that it's properly sealed.
This is a strange one. I bought one of these a few weeks back:
http://www.amazon.com/Silicon-Power...&redirect=true&ref_=oh_aui_detailpage_o00_s00
It's been working fine for me. Yesterday, my tablet just hung. Like I could barely click on anything, and then when I could, it only seemed to last for a few seconds, and right back to totally hung. I had to force reboot my tablet, but it was not very long upon reboot that the same thing started.
I turned to google for advice, and one site recommended un-mounting my sd card. Well. yeah, doing that seems to have resolved the problem. It has been running completely fine ever since.
My question: Does this mean I have a bad SDcard, or is the problem with the tablet? Is there a way to know. I don't have the same problem when I plug this sd card into my windows computer.

Highly likely the sd card.
I bought one of those also and had the same problem. I returned it to Amazon for a refund.
Stick to decent cards like Samsung Evo.
Use cards which are U3 rated for fast writing.
