Problem #1: Galaxy S5 Gallery app won’t open if Location and Calendar permissions are denied

I just bought a brand new Samsung Galaxy S5, and I’ve been personalizing it while I await the SIM card from my service provider. I’ve started to notice a lot of the apps, which came with the phone, seem to ask for various permissions, but when I deny them access to their requested permissions, the apps refuse to run. It’s one thing if the apps would run with limited functionality, but they do not even open at all. As a general rule for my privacy and security, I tend to not like apps/programs accessing extra information. However, in many of the cases for the apps, which come with my phone, I don’t feel like they absolutely need to access what they are requesting permission for. It seems incredibly intrusive to my privacy/security. One glaring example is the “Gallery” app. Whenever I try to start it up, or another app in the phone needs to interact with it, the Gallery app brings up a couple of permission request windows: “Allow Gallery to access this device’s location?” …then… “Allow Gallery to access your calendar?” After denying the both of them, it quits me back to wherever I was before. I really don’t understand why the Gallery app would absolutely need to know my device’s location and/or what might be on my Calendar. All I want to mainly use the gallery app for is to view my stored images. If all I want to do with the Gallery app is look at my image files, then why the hell does it need to know my location and/or my calendar? That seems very intrusive and suspicious. This particular issue with the Gallery app especially pisses me off because I want to change my wallpaper to a flat black background. I think a black screen will be more tasteful, simple, and easier on the eyes than the stock wallpapers, which come with the phone. Due to a black wallpaper image being completely monotone, it theoretically should require less memory to display, while definitely also saving a significant amount of battery usage due the screen’s AMOLED display.

Regardless, whenever I go to change my wallpaper, and choose “From Gallery” to select my all-black image, the Gallery app requests permission to access the device’s location and calendar. Of course, when I deny both of those, the Gallery doesn’t even run, so this problem is not even let me do a simple thing like changing my wallpaper to a custom image. The Gallery app is definitely not the only app, which will not run when I deny permission requests, but it is the most annoying to me at the moment while also being a type of app, which I would think should not need to access much info at al from any other sources except itself and perhaps the files it views.

Technical details about my new phone:

1) I bought it brand new from a respectable online dealer. After reviewing some fake-phone videos and using my phone for a couple of days, I am confident my Samsung Galaxy s5 is authentic.

2) When I got the phone, it had an older Android OS, then I set it to update overnight. I know it updated to 6.0.1, but I didn’t pay attention to what the OS version was before it updated. Either way, I was encountering the same problem before, and I was really hoping the OS update would resolve my issue, but obviously it did not.

3) So far, I haven’t installed much at all on my new phone, so it is not like there should be any bizarre conflicts going on in the background. Besides copying over some image files/videos via a USB connection, and installing the “SD Insight” app, which authenticates legitimate MicroSD cards, I haven’t put anything else on my phone. I think all this information should be enough to give anyone a comprehensive idea about the problem, which I am encountering with apps not running without accepting their permission requests… more like “demands” if you ask me. I really hope this issue can be resolved/circumvented, but I have a very bad feeling I’m going to have to end up sucking in my personal preferences and potentially compromising my privacy and security. — Tone

Solution: Hi Tone. The use of the word “Permission” by Google to let a user know what type of information an app may use can be misleading to most average Android users. That’s because while Permission in Android’s context does work as intended by Google, it is also just a formality telling you to grant the request. Generally, when an app asks your permission it does mean you have to handle it positively or you’ll be unable to use the app. The importance of each permission is determined by the app developer. That means that if their app is designed to not work when a certain permission is denied, a user like you should opt to either grant the request or not the use app at all. It’s an either or situation.

We understand your concern about some apps being given too much access to our data but we’re really at the mercy of developers regarding this one. What we don’t understand though is why your phone’s Gallery app requires access to Calendar. Checking on a number of our devices running Android Marshmallow (we checked a Galaxy S7, a Galaxy Note 5, and a Galaxy S6), we can’t see the Gallery app asking for permission to access Calendar. The only permissions listed under Gallery app includes Contacts, Location, Phone, SMS, and Storage. The reason why the Gallery app needs Location access is to ensure that GPS-tagged photos and videos are stored properly. We can’t see any reason why such an app may require a Calendar access though. This additional permission may be added by the particular operating system version running on your device so we really don’t know. If the OS update was provided by your wireless carrier, we recommend that you contact them so they can report this particular issue. If you manually flashed the firmware yourself, you may want to consider flashing official Samsung firmware.

Problem #2: Verizon Galaxy S5 mobile data won’t work on AT&T network

I purchased a Verizon Samsung S5 that was supposedly unlocked and able to be used on any network. I want to connect it to AT&T. I have contacted Verizon who informs me that none of their phones are locked, and I have contacted AT&T who went through the APN settings with me to set it up for AT&T’s network. I cannot get it to connect to the mobile data. It connects to the network to make phone calls and send texts, it connects to my wifi, but when I turn the wifi off or am not in range of wifi, the mobile network does not connect. It is set to ON for the mobile network and roaming. I have created two APN settings for AT&T, one for 3G and one for 4G, neither work. Across the top of my screen, next to the bars that show connectivity, there is only the letter H, it is not lit up, and when I turn on my wifi, it shows 3G in that spot. This is the second phone I have that has this problem. I have a third phone that is exactly the same kind and it works fine. Help, in any way you can. Thanks! — Switchblade74

Solution: Hi Switchblade74. Verizon uses CDMA technology as opposed to GSM of AT&T. This means that there’s a chance all functions of a Verizon phone may not work properly when used in a another network. If you’ve already contacted AT&T to ask for correct APN settings and nothing changed, something deep in the operating system may be the problem. CDMA phones are more difficult to reconfigure so it can be used in another network. There must be some coding issues that prevents the phone from connecting to AT&T’s network. If that’s not that, the fault may be on the provisioning side of AT&T. whatever it is, we suggest that you work with AT&T technical support to fix the problem.

Problem #3: Galaxy S5 browser won’t load a page when connected to unsecure wifi or public hot spot

Problems that have been on unsolved on any website since Marshmallow update (6.01).

  1. when connecting to public wifi or hot spot Google states not secure and will not load page. (try to go to any website and check tabs for guest log-in but can’t get to it.
  2. Constantly opens up to google.com search page (every few seconds) if wifi connection exists. Opens google.com less frequently when wifi is off but still interrupts whatever you are doing.
  3. Check battery cover opens constantly.
  4. Google Maps keeps going offline to open google.com website (part of problem 2.)

Fixes I have tried:

  1. Remove battery while on and wait 2 minutes before reinstall.
  2. check for updates
  3. clear/wipe partition
  4. re-install Google
  5. Visited AT&T forum ( many with same problems but no answers), visited GottaBeMobile, Samsung website, Google marshmallow fixes, s5 forum. Please your help would be greatly appreciated.

Also, if I root the phone and install custom ROM would this probably solve problem? What would you recommend installing after rooting phone: titanium back-up? 2. Clockwork? 3. Odin? Bitdefender virus protection? Any others that would be useful? I am intermediate in skill level with Android so thanks for your help! Please give me link and i will donate to your website maintenance. Your site is a great resource!! thank you. — Cheryl

Solution: Hi Cheryl. First of all, we want to make it clear that we don’t cover rooting-related issues in our blog. If these issues occurred when your phone is running a rooted system or unofficial ROM, you must ask support from the developer or community that helps develop the said root or custom software. Rooted phones can have issues that may be caused by a unique bug from root or custom software so the solution may also be provided by the community that builds it. Kindly reach out to them to get effective solutions.

Secondly, we don’t accept donations but thank you for the concern. We just want to contribute something positive to Android community and letting us know that our blog is helpful is good enough.

Now, assuming your phone is not rooted and runs official Samsung software, below are our answers to your questions.

  1. This issue may be isolated to your browser so the first thing that you want to do is to wipe the browser’s cache and data. Here’s how:
    • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
    • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
    • Once in there, click on an application.
    • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
    • You should now clearly see the Clear Data and Clear Cache buttons for the application.
  2. Try to boot the phone to safe mode and observe. One of your third party apps may be creating a conflict with others apps or the operating system. Safe mode prevents third party apps from loading so if the issue won’t happen, that’s a clear sign that an app is to blame. To boot in safe mode, follow these steps:
    • Turn the device off.
    • Press and hold the Power key.
    • When ‘Samsung Galaxy S5′ appears on the screen, release the Power key.
    • Immediately after releasing the Power key, press and hold the Volume down key.
    • Continue to hold the Volume down key until the device finishes restarting.
    • Safe mode will display in the bottom left corner of the screen.
    • Release the Volume down key when you see Safe Mode.
  3. “Check battery cover” message is one of the pop ups a user will get if the phone senses that the back part or battery cover is not in properly in place. For some S5 models, this pop up will fade after showing up several times but other models may show it as a persistent message. This means that you either don’t follow correct instructions in securing the part involved, or there’s a software glitch causing it. If you are 100% certain that the battery cover is secured but the message still persists, consider doing a factory reset. Here’s how:
    • Power down the Galaxy S5.
    • Press and hold the Volume up button, the Home button, and the Power button together until you see the Android on screen.
    • Use Volume down to highlight the wipe data/factory reset option and press the Power button to select it.
    • Use Volume down again to highlight Yes – delete all user data and press Power to select it.
    • Use the Power button to select Reboot system now.
    • When the S5 restarts it should be completely wiped and ready to set up again.
  4. Refer to our suggestion for item #2. If the issue continues even when device is on safe mode, do a factory reset.

Again, we don’t support rooting- or flashing-related questions so kindly visit other sites that do. XDA Developers forum is good place to start.

Problem #4: Galaxy S5 question about rooting

Hello. I’m writing because I’m so NOT tech savvy. lol. Anyway, a while ago by accident I deleted my picture Gallery. I WAS DEVASTED! All my kids pics, videos blah blah blah. Anyways, I downloaded Dr. Phone and got them all back. Does this mean I had to root my phone to get them back? I have no idea what that even means, just learning from researching how to fix.

Anyway, after that the custom unlocked pad lock picture shows up at first boot up. Wasn’t sure what it was but my phone acted fine, always booted normally, other apps updated, just the custom unlock thing still shows up. However, everyday since an update wanted to happen its always unsuccessful.

So my question is do I have to re-root my phone (whatever that means)? Just so you know, I also downloaded Super SU and that said I have to update the binary (whatever that is). And that’s where I stopped because I don’t wanna ruin my phone. So could you please help me with my update, re-rooting and binary…again, whatever they mean? Thank God for peeps like you. Don’t know what else to do. Thanks! — Rebecca

I’d be happy to answer any questions.

Solution: Hi Rebecca. We are not familiar with how Dr. Phone software works in retrieving files but we believe it needs to root the target device first to be effective. If they did root your phone but did not revert the software back to its official state, you will have to do some research on how to bring your phone to its stock state. Rooting a phone means unlocking previously inaccessible folders, and critical files. And mind you, there are reasons why some folders and files are designed to be inaccessible to average users. One important reason is to prevent users from tweaking files or folders that may be critical to the operating system. Another reason is to prevent apps from accessing sensitive user information. In other words, rooting gives a user unrestricted access to core system files and folders but at the same time weakening the built-in software security. With a rooted phone, a malicious app can now easily access sensitive user data. This is the main reason why rooting is only recommended for advanced Android users — those who are aware of the risks involved and knows how to deal with them. Google and hardware makers like Samsung discourage users from rooting their phone for the same reasons above as well.

The answer to your question about re-rooting your phone is no. You only root an Android device once.

SuperSU is an a popular app that helps a user manage app requests for root permission. Because granting root permission for every app after rooting a device can be quite tiresome, SuperSU does the job for the user. If this app asks you to update itself at this time, you can go ahead with it.

Now, since you’ve already recovered your precious digital files, make sure that you back them up to another device like a computer, another smartphone/tablet, or to a cloud service (like Samsung Cloud, Google’s Photos, or Microsoft’s One Drive) to avoid risking another loss.

Problem #5: Sprint won’t replace a Galaxy S5 with a manufacturer issue

Few months ago, the Android phone I have thru Sprint, that my mom & step dad pay for, wouldn’t turn on or off. When we went to Sprint store they did test & determined it was a “manufacturer” issue. Yet they were unable to give me the correct manufacturer contact info. My mom complained enough that they decided to give me a ONE time only replacement S5 (after weeks of complaining). Now same crap is happening, so I will just live without it working. Unfortunately my mom & step dad still are obligated to pay for 2 more years on it. It’s load of crap. My question to you is, if you believe the “manufacturer” issue is reasonable & shouldn’t all phone distributors keep records of who their manufacturers are for their products? I’m not asking you to slam Sprint, just your general opinion regarding this conclusion regarding my device. No one else will chat with me about it. I apologize for sounding desperate, but my entertainment is only my phone, due to unforeseen medical financial issues. Thank you in advance for your time with this, I know you all are extremely busy. — Lisa

Solution: Hi Lisa. If the problem on your phone is indeed due to a manufacturing defect or design flaw, there should be a proper channel that you can take to get a resolution. In most cases, defective units can be returned to the place where you get it from, be it a Samsung store, a retail store, or your carrier’s store, as long as the device was never mishandled by the user. Mishandling in this case covers a broad spectrum but it usually refers to scratches on the device and physical damage. For example, if you return your device a day after unboxing it but scratched the screen or other parts by accident, the store may not honor the replacement warranty. The same is true for a water-damaged phone, or a device with a broken screen. Be sure to consult the warranty that came with the device so you’ll know the specific terms for the coverage. If Sprint won’t honor the warranty for some reason, you can always call Samsung’s customer service or visit their website, https://www.samsung.com/.

Problem #1: Galaxy S6 only charges up to 90% | Galaxy S6 won’t fully charge to 100%

Hello. My phone used to charge really quickly as i have fast charging but yesterday i saw that it charged fast from 44% to 80% but when it reached 80% it becomes so slow. It takes above 10 minutes to reach 81% so the problem is not with the adaptor or the cable i guess. I left it for 3 hours in charge even, after that it do not go above 90%. But if it does reach 100% when i remove the charger cable it went straight back to 90% or 89% in less than a minute. My phone used to charge from 15% to 100% in less than 1hours and 15mins.. 🙁 Please help me!! — Nirvanee

Solution: Hi Nirvanee. The operating system may not be reading battery level properly at this time so what you want to do is to retrain it. This is called battery calibration. Here’s how you do it:

  • Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  • Turn the phone on again and let it turn itself off.
  • Charge the phone without turning it back on.
  • Wait until the battery says it fully charged to 100%
  • Unplug the charger and turn the phone on.
  • If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  • Unplug the charger the turn the phone on again.
  • Use the phone until you drain the battery down to 0.
  • Repeat the cycle once.

Problem #2: S Voice app gone after installing Marshmallow on Galaxy S6 Edge Plus | OK Google not working on Galaxy S6 Edge Plus due to “microphone is not reachable, please reboot your phone.” error

Hi guys. I arrived to your posts due to a problem I am having on my S6 Edge Plus. I have just upgraded it to Android Marshmallow and when I turn it on I received a notification that I must download a S Voice service provider. But when it takes me to the Galaxy apps page it says there is no application compatible with my device and closes it back. The OK Google function doesn’t work either because it says “microphone is not reachable, please reboot your phone.”

I guess the S Voice app is messing somewhere around but I do not where to look. I tried disabling it and also erasing cache, installing it back but the error persist. Would you help me? I do want to take the factory reset option (yet).

I attached some screen captures in case it helps. Thanks a lot for your time!

Atentamente. — Federico

Solution: Hi Federico. If the Clear cache and Clear Data buttons on the S Voice app info page did no help, the only solution left for you is factory reset. This will force the phone to restore all software defaults, including that of S Voice and OK Google. Here’s how to do it:

  • Turn off your Samsung Galaxy S6 Edge.
  • Press and hold the Volume Up, Home and Power keys together.
  • When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  • Wait until the Android Recovery Screen appears after about 30 seconds.
  • Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  • Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  • After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem #3: Waive fee after returning a Galaxy S6 Edge to store

Hi. My name is Connie and I have a Galaxy S6 Edge. It fell in the toilet. For one day I put it in rice hoping it would helped. It didn’t turn on. I took it to the store to see what my options were, but they said there was nothing I could do to revived it and that I had to buy a new one! I didn’t want to give up on it, because it had my pictures of the last year are in it.  When I got home,  I contacted the Samsung support and they also, corroborated what the seller guys told me at the store. “There’s nothing you can do, it’s broken, you need a new one ” and since it was my fault for not having it synchronized with my Gmail account, (which I was never told about the importance of it) I believed them, and I  bought another one, but still I didn’t want to give up on it!

So, I connected to the charger and my heart jumped in excitement! No one told me to connect it, they just wanted me to buy the next one. Surprisingly, in an effort to recover my history in pictures of the last year,  I just connected to the charger and it turned on!!! I don’t know if it’s going to work well, but so far, it’s doing good. 

The problem is that now I have two cellular phones and I don’t think it is fair that the customer support didn’t do what they’re supposed to: help the customers and provide specialized service and support when we need it most. 

I’ll have to return the new phone, but they’re going to charge me  with a restocking fee of $50. What can I do to wave that fee? If there’s anything that I can do,  please,  let me know! I’ll really appreciate it! — Connie

Solution: Hi Connie. First of all, we want to emphasize that exposing internal components to liquid can both have short-term and long-term damage if not dealt properly. If by some miracle no liquid was able to go inside the device and touched any electronic component, that’s good. We don’t think that’s the case though since you were not able to turn it back on right away a day after the phone took a dive. Unlike the Galaxy S5 and Galaxy S7, both of which enjoy some form of water protection, the Galaxy S6 Edge does not. If the water exposure is that extensive, you still want to have the hardware checked (and cleaned) just to be sure. That means opening the device and thoroughly checking the motherboard. Keep in mind that corrosion on the motherboard can sometimes take weeks, if not months, to become full blown, meaning there will be permanent damage in the phone. Opening the phone will allow a technician check if there’s a developing corrosion at this time. If that’s the case, it’s only a matter of time before the device will start showing problems. If there’s a repair center in your area that can check your phone, make sure not to skip it. This will not only put you in a better position to decide whether or not to go ahead with the return of the new phone, but will also help set expectations that your current damaged S6 will not last longer than usual.

The answer to your main question really depends on the store’s policy regarding items being returned. It’s common practice for stores to charge a customer if they return an item before a specified date but some even won’t accept returned electronic devices at all. You have to talk to the store’s management if you want to exempt yourself from their usual policy regarding returned items.

Problem #4: Galaxy S6 Edge Plus S Voice questions | How to launch S Voice in Galaxy S6 Edge Plus

Hi there. I have the Samsung S6 Edge Plus and it’s pretty good so far. But it’s very different from my Note 3. When I used to use the S voice and talk to Galaxy I was able to do that with the home button. For some reason that doesn’t look like an option for the S6 Edge Plus. Is there any way to make S Voice my home button again or is that impossible. Also I noticed that the S Voice talk very fast and sometimes I can’t understand what it’s saying. Is there a way that I can actually make it talk a little bit slower. It basically sounds like a little robot. I hope that you can take the time to actually read this email and actually help me. Thank you for your time. — Janice

Solution: Hi Janice. In older Galaxy S devices, S Voice can be launched by tapping the Home button but in the Galaxy S6, that same button is now reserved for Google Now. In order to open S Voice in a Galaxy S6, S6 Edge, and S6 Edge Plus, you must either go via the Application drawer or wake it up using voice commands.

As far as the S Voice voice is concerned, no, there’s no way you can change the rate of its speech. This is a proprietary Samsung virtual assistant software just like Siri in Apple devices so user or community modifications are not allowed.

Problem #5: Galaxy S6 showing “no images/videos available” warning when opening Gallery app

Hello. I apologize for bothering you with this minor issue. On my Galaxy S6 when I attempt to open the Gallery. it looks as if it’s opening then all of a sudden I get a “no images/videos available” and it closes automatically. I then cleared cache & data and didn’t help. Then I entered safe mode & attempted to open it and this time it opened. So I know it’s not a firmware issue. So I cleared cache & data once again. I came out of safe mode and once again attempted to open the gallery & received the “no images/video’s available” warning. Just to clarify this “no images/video’s available” warning isn’t a warning box that pops up & has an OK Box that I can clear. It’s just one that pops up & instantly disappears as the gallery closes. So now I’m stumped as I can uninstall & reinstall as it’s a pre-loaded app. That’s why I’m bothering you with this. Thank you for taking the time to read this & I look forward to hearing from you. Respectfully. — Ron

Solution: Hi Ron. If the Gallery app works normally when you first boot the phone to safe mode, then that means that a third party app (and not the Gallery app itself) is causing the problem. You don’t need to uninstall the Gallery app but need to identify the cause. To do that, you must remove third party apps one by one until you will be able to open Gallery app in normal mode. For example, if you have 10 third party apps installed right now, you need to uninstall them individually, making sure that you check how Gallery app works after each app removal — uninstall and observe, uninstall and observe. Do this same cycle until you’ve removed the cause.

Problem #6: Galaxy S6 keeps freezing, randomly rebooting, and showing black screen after installing Android Marshmallow

Hello. Samsung Galaxy S6. It seems that since the most recent update to Marshmallow, my S6 has been freezing multiple times a day (on average 4 times), rebooting on its own, going to a black screen and then not being able to turn it on or off. I have tried factory resetting the device multiple times, wiping the cache, forcing it to turn on and off using the home, power, and volume down buttons, but nothing seems to work. I even sent it in to square trade to get looked at, they replaced the battery, but it didn’t help. — Megan

Solution: Hi Megan. Another good thing to do if you experience problems after a software system update is to ensure that all apps are compatible with the new operating system. This is the most often overlooked solution to post-update problems. Not all developers are keen enough to make sure their apps will work with the latest Android version. Do another round of factory reset and observe how the phone works without installing any app. If the phone works normally without the apps, that should tell you that our hunch is correct. Again, don’t forget to update apps. Try to check if each of them is updated to work with Marshmallow. If you aren’t sure if one is compatible or not, don’t install it.

Problem #7: AT&T Galaxy S6 won’t work on Sprint network

I got a real good deal on a Samsung Galaxy S6 64 GB phone that was AT&T owned.  I requested a unlock AT&T so that I could activate my phone with my carrier Sprint which I am a Boost Mobile customer. AT&T were very helpful and help me get the phone unlocked and I did so.  I then went to activate it and Boost Mobile could not activate the IMEI number so they would not activate it for me. So I called AT&T asked them if the unlock was done right; they said it was. The problem is that Sprint and Boost Mobile do not do SIM cards in their phones as a main stay as far as SIM card go. So that is why they cannot locate the IMEI number. This is where my question lies: how can I get Sprint to accept this phone and let me activate to continue my service with them?

I did all the reading I could and thought I had done my homework before getting the phone. I did not read or hear that Sprint does not like to take phones that don’t have them listed as prime source. I’m confused on what to do and how to continue. If anyone can trouble shoot this for me I would be grateful. I just don’t know how I can get Sprint to except the IMEI number when they won’t even help me get it activated.  Very sad to have this going on with Sprint. I had their back until now and now I am not so sure.  — Darrin

Solution: Hi Darrin. The main reason why you’re having this problem right now is incompatibility. AT&T uses GSM technology while Sprint in on CDMA. Both of these technologies don’t mix, which means that, in general sense, you can’t use an AT&T device on Sprint network and vice versa (there are a few exceptions of course but they depend on what type of phone you have). We know that AT&T has already unlocked your phone but it only means that it can now use another SIM card from another GSM network and nothing more.

Wireless carriers that uses GSM technology store subscriber information on SIM cards. As long as the phone is not blacklisted, has been network unlocked, and you have an activated SIM card, you can use the phone on any GSM network. This is not true when moving a GSM phone to a CDMA network like Sprint.

CDMA networks does not use SIM cards to store their subscriber’s information. Instead, these information are programmed into the phone itself so it’s more difficult to make a CDMA phone work on a non-CDMA network. While most CDMA phones nowadays have available SIM card slot, this is not to allow these phone to work like regular GSM phones. The SIM card slots on CDMA phones are there to allow 4G LTE to work, since LTE technology is just a modified GSM technology. Subscriber information are still stored in the phone itself and not on the SIM card. CDMA phones’ hardware are built significantly different from GSM phones even though they may be of the same model line. Even CDMA phones outside of Sprint (like the ones from Verizon) may not also work due to this limitation. This is the main reason why your network unlocked AT&T S6 won’t work with Sprint. Even if the phone’s IMEI is not blacklisted, there’s just nothing Sprint can’t do about it because the problem is on hardware level. We’re pretty sure Sprint would love to welcome you in their network but your phone is not just compatible with their system.
