I'm randomly getting a invalid SIM. Sometimes this causes the phone to do this stupid countdown thing and restart. Is anyone else seeing this issue, does any have any idea how to fix it? I requested a new SIM card but it's not fixed the issue in the slightest.

I'm on KK and haven't received an update to Lollipop. I know KK changed the write permissions for the SD cards and there is a fix if you have root. I don't want to root as I'm waiting for the Lollipop OTA. When I tried to use the microSD card for the camera app it tells me the card is full. The card shows 31.72gb free in storage though. I tried copying files to the card with a 3rd party app, which of course did not work. Also I see no way to copy files to it using the default file manager. In KK Samsung allowed the camera to write to the card and the default file manager. Did LG not build that in? It has no problem reading the video and audio I have on the card.

I have problem with my 4gb micro sd card...i put some MP3 files but when 3.59gb is remaining every files that I put doesn't play...it says 'this player does not support this type of audio file'
I have use a different music app rocket player...i have tried everything but problem still the same
What can i do??

Hi
I bought an S3 cheap that has no IMEI just to use it as a flight instrument (variometer) because of the built in barometric sensor. My problem is, that even it doesn't have a sim card inserted, cell standby still draws huge amount of juice from the battery. It is like 85% of the battery usage. In battery stats it shows the red bar signalling that it has no cell coverage, but still looking for it. :eek: I even put it in airplane mode but to no avail. How could I get rid of the cellular function of the phone for good ? I would even open up the phone and cut wires if needed. :) I am rooted.

Thanks!

Hello, guys. I've been having some weird problems with my Xperia M and a SanDisk 8GB SD Card. So, here's what is happening: I can only edit files in the SD Card with any file explorer app in the Xperia M or by connecting the Xperia M with an USB to the PC. Any other ways will result in failure and a message that my SD Card is write protected. Can anybody help me fixing it? I know the SD Card is not broken because it works perfectly with the Xperia M.

Can't find any mention of this specifically. But apps be installed/moved to the SD card?

I have a ext4 micro sd card with 128 GB but my note III device does not seem to recognize it.

It says: Checking sd card but nothing happens.

I used sdformatter and partition wizard for a clean ext4 formatting!

I use now temasek cm12.1 which actually should have ext4 support!

Hey. Hope you are all okei

Hello I've seen videos on YouTube on straight talk using Verizon lte and there data speeds where like 16+ and I get only 5mbps. Even with full bars of 4gLTE ? When I do speed test I see it say 13 but Gos to 5mbps?

One of the reasons I got this phone after having a G2 for a year was to be able to use external storage. Well I am now on my second 128GB sd card, which the phone is supposed to be able to recognize, but it's all but useless. When I inserted each card the first time the phone recognized it and was able to mount it and I was able to write to it. But whenever I tried to copy files using a file manager (I use Total Commander with root access) it will tell me to "select the root of the SC card to gain access" or something similar. So I do that, but it still fails to be able to write to it. Sometimes it causes the SD card to unmount and not be readable by the phone at all except in recovery. I'm on stock 5.0.1 from T-Mobile. Is this an android issue or a phone issue? The first sd card is totally corrupt - I can't even mount it on my PC to format it. I want to find out what the problem is before corrupting this one. The second one I just tried getting permissions using my QuickPic app to copy files over, and I followed the instructions to gain write permission and it seemed to indicate it was successful. But nothing was copied. Then suddenly the SD card was no longer mounted and the OS doesn't see it. I rebooted in recovery and it sees it there. I tried formatting the last one in recovery and that's when it got so corrupted that it was not usable. Any help here?

Hi!
my Nexus 6 detects no SIM card, I bought it used and with this problem. I'm from Europe and I suspect that the phone could come from US . This could have something to do ?
What can I do?
Thank you very much !

Apologies if this is not the correct forum but it relates to my Tab S 10.5 and a Sandisk 32Gb SD Card.

Please bear with me because I'm wracking my brains trying to work out what's wrong.

The card was working fine up until today when I decided to copy everything from the card onto my PC. This it did with no problems. I backed up the whole card to a folder on my desktop. I then reformatted the card.

When I came to copy the files back to the card, they wouldn't. I just got the 'copying' bar until eventually Windows said 'can't copy'.

Ok, I thought, must be a dodgy card. So I checked the tablet and all seemed fine. I could transfer files from internal storage to the card and back again but try as I might, I just cannot get anything from PC to tablet. Windows 7 Ultimate 64 bit.

Anyone any thoughts at all?

Having been a Sprint customer for years, I'm not that familiar with SIM cards, but I know that the S6 has one. For international travel, if I want to use local cell service, is it truly as simple as buying the right kind of SIM card and swapping it in?

My phone is rooted

Before this problem :

I flash my own port Rom using cwm.

And no problem on my ported Rom.

After I decided to flash another Rom it's ok nothing changed but when I flash ported Xperia Rom from the owner (not me) ,and I get the problem. No sim card detected.

I don't know why, but maybe because the Xperia Rom is cdma gsm, so my phone can't detect that because my phone is gsm gsm.

After that, I flash stock Rom and the problem still there.

Please help. Thanks

Hi, I recently got a Samsung Galaxy S5 and I bought an SD card for additional storage since the phone only has 16GB. Just in case, the phone is not rooted. I was trying to install an app earlier today and it wouldn't install because I didn't have any storage space left on my device. I wanted to know if there is any way to set the SD card as the default directory when downloading apps, stuff from the internet(videos, music, pictures), taking pictures and videos on the phone, etc. Thanks

Hello,

Long time lurker..Just picked up a new 3840 from Newegg for 100 bucks for reading my comics. I have seen all the negative reviews but figured for that price I would give it a shot, plus I could return if it really was awful. So far, so good! And I still haven't done the OTA updates yet....so I am cautiously optimistic. Anyway, does the 3840 in fact support a 64gig micro sd card? It states on the Dell product page that it does but, when I pop in my Samsung 64g card in with all my comics it says the card is blank in the notifications bar??

:confused: Any ideas? I want to get another 64g card for this tab but don't wanna blow the money on it if it's not going to work!

Thank you for any help

Hello everyone!
I've recently ported a ROM for my device and I've encountered a common problem. SD card is not shown/can't be mounted. After hours of trying the obvious common solutions...I still can't get it to work. I've replaced the vold(from bin), vold.fstab, ported the mountfiles from boot.img, replace the storage.xml... and nothing worked. The closest thing that I manage to achieve is to have the sd card mounted as internal storage, but this throws error like android.process.media and settings app crashing.
Please advise me in what can I modify/replace to make it usable as external storage.

Thanks in advance!


P.S: I've attached the "ported" vold file.

Hi Guys, Today I'm gonna show you the way to give permissions to save Downloaded Files on SD Card. As You Guys Know In some MTK Lollipop phone, users can't download / Move Anything on sd card. Because Google Has restricted some permissions. But There Is Still a way to do it. Let's Check It Out
To Do This You Need
1) Rooted Phone
2) Nandroid Backup (Incase You Brick Your Device)
Okay Let's Start
1. First Grab Some Popcorn :D
2.install Root Explorer ( As It's A Paid App, I'll Not Provide The Download Link)
3.open it.
4.go to the following folder
root>system>etc>permission
5.find the platform.xml file...
6.open it with text editor.
7.find the following line
name="android.permission.WRITE
_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
</permission>
8.add this extra line
<group gid="media_rw" />
9.like this
name="android.permission.WRITE
_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>
10.save it and take the platform.xml.bak
to your sdcard
11.reboot and enjoy...
Thanks

So I noticed after taking my phone off airplane mode for so long that I have a no sim card inserted error
The thing is I do have a sim card inserted and the weird thing is when ever I take out the sim card, instead of the bars getting an X for disconnectedness, apparently I still have service. and I've been reflashing my tmobile d801 to gsm and not cdma
I've reflashed 3 different ROMS to see if it would get rid of this error but it hasn't.
I have taken my phone apart to see if the Sim card slot was loose and it's not and all the pins are fine
I've taken the sim out and turned the phone off for 1 minute and that didn't help
I have blew air in the sim card slot for curiosity and nothing.

I'm all out of ideas, anyone can help?
Could it be the modem?
