Problem #1: Galaxy S6 edge Bluetooth won’t connect to Ford G6E car kit system

Hey there, I am having a huge issue with the Bluetooth on my S6 edge. I’ve been over all your troubleshooting and none seems to have exactly the same issue. I’ve just upgraded my 2012 XR6 for Falcon to a 2013 Ford G6E, (which is supposedly the updated model year too). My phone’s Bluetooth would connect perfectly with my old car, even with Marshmallow (phone’s always fully updated), no issues. But as soon as I got in the new car, my phone won’t even recognize a Bluetooth source. I have personally seen a pile of other phones connected to the new car. And mine will not even find it! Bit of a frustrating issue! I have cleared the Bluetooth cache and data and cleared my car’s previous connections, reset my phone, Bluetooth and car countless times. is there anything you can suggest? Thanks:) — Dduffy060

Solution: Hi Dduffy060. In many cases, an issue like yours is caused by incompatibility. This means that one of the devices may not be equipped to handle a connection with the other at all. Like other Android issues, the only troubleshooting that you can do are the things you’ve already tried (wiping bluetooth and system cache, factory reset). If the issue remains after that, you can bet the problem is with your car’s bluetooth system. Consider calling the car maker so they can check if there’s something that they can do.

Problem #2: Galaxy S6 won’t fast charge anymore

Hi. I’ve been having slow charging issues with my Galaxy S6 for a couple of weeks now. It all started when i was fast charging it. It fell right on the connection between the port and the USB cable. The cable bent and I thought the charger stopped working because after that, it wouldn’t fast charge anymore. Instead, it started slow charging. I changed the cable and it still did the same thing. I figured maybe my phone’s port was damaged so I took it to a technician who couldn’t find the problem and said the port was just fine.

Also, when i connect it to a PC, there’s always a USB error, so now I can’t transfer files to my computer from my phone. Please help! I already tried wiping the cache and factory resetting my phone as well 🙁 I should mention that a day or two before i noticed this problem, my phone had just done a system update. — Noemi

Solution: Hi Noemi. Erratic charging behaviors and USB error are some of the clear indicators of a bad micro USB port. A pin or two may have been bent causing poor or no connection when you insert a USB cable to the port. Try using some magnification to inspect the insides of the USB port and see if that’s the case. Sometimes, lint or dirt can also cause improper connection with the charger so try to clean the port as thoroughly as you can. If you can see a bent pin, try to check if there’s something that you can do to straighten it out. If you can’t do it, consider sending the phone to Samsung so they can replace the defective component.

Problem #3: Unlocked Verizon Galaxy S6 edge can’t connect to Personal Network in Argentina

My daughter has a Samsung Galaxy S6 edge from Verizon. We are told by Verizon that the phone is unlocked. She is in Argentina and has purchased a local SIM card from “Personal” and is unable to get the phone to connect to the Personal Network (which does show as an option on her screen. She gets a “Unable to Connect” error. We have spoken with Verizon and they walked her through the recommended changes in settings, but it didn’t work. She tried a second SIM card from the same vendor – no luck. I took a guess on the Android operating system below – I don’t know and can’t contact my daughter now. Any advice? Thanks! — Liz

Solution: Hi Liz. First of all, we want to make it clear that Verizon uses CDMA technology, which is entirely different from GSM. Unlike GSM phones that uses SIM cards to store subscriber information, CDMA phones utilize special software to keep subscriber information deep in the phone itself. This means that a special software is also needed to reprogram the device in order for it to work with other networks. Most of the time, such special software are not publicly available, or may be difficult to obtain, thus reprogramming a CDMA phone is usually a business for the CDMA carriers. GSM phones on the other hand can easily be unlocked; once you’ve inserted an active SIM card (and provided the new network is compatible with the phone’s operating frequency, which is another topic), everything should be good.

Secondly, unlocking a CDMA phone means that it’s no longer bound to one network only. Verizon does not generally lock phones obtained via postpay service, which means that there’s no special reprogramming codes needed to make it to work with other networks. For prepaid phones, this policy may be slightly different. If you are 100% sure that the phone has been unlocked, then you can skip this topic.

Lastly and more importantly, “unlocking” does not mean that the phone can now work with all carriers. Keep in mind that each carrier can use different technology (generally either GSM or CDMA). Even between two CDMA carriers, there’s no guarantee that your phone will work as expected. In the US for example, using a Verizon phone in a Sprint network, which also uses CDMA technology, is not just difficult but almost always result to failure. The same can be said when porting a CDMA phone to a GSM network. Verizon phones are notoriously difficult to crack and most of the time, not all services will work. We’ve documented a lot of users with Verizon phones complaining that their SMS and MMS services won’t work, or are erratic.

Then there’s the fact that each phone is built by Samsung to operate in certain frequency bands of the operator only. For example, Verizon’s S6 phone is designed to work in these frequencies:

  • LTE Band 13/4/2 (700/1700/1900 MHz) out of box;
  • LTE Band 3/5/7 capable (1800/850/700 MHz);
  • CDMA/1xEVDO Rev. A (800/1900 MHz);
  • Global – EDGE/GSM (850/900/1800/1900 MHz),
  • HSPA/UMTS(850/900/1900/2100 MHz).

The phone’s capability to work in these frequencies are made possible by specific hardware chip. “Unlocking” a device means reprogramming the phone in order to disable the software that can prevent it from connecting to other wireless carrier’s network. Unlocking won’t change the hardware of the phone. Thus, if the network where your daughter is located does not support these frequencies, there’s no way that Verizon phone will be able to connect. Unlocking, in other words, does not make the phone interoperable with all wireless networks. This may be the reason why she’s now having trouble connecting to her new network. There’s no amount of software troubleshooting that can be done to fix the issue.

Problem #4: 2degrees Mobile Galaxy S6 international roaming not working in Australia

I have a New Zealand 2degrees Mobile account. I have arrived in Australia 2 days ago, forgot about setting my Samsung S6 up for international roaming, and I’m having no success in setting it up for international roaming. I have followed your 2degrees online instructions including: under ‘network operators’ selecting ‘Select automatically (Automatically select preferred network). It proceeds to process this instruction for a very long time, then comes up with ‘Unable to connect, try later’. I have tried this numerous times with the same result. I have tried turning the phone off, turning the phone back on…result: tried calling an Australian cellphone number…didn’t go thru “Not registered on network”. Rang the network provider back in New Zealand (via another phone) and spent about an hour with them…they were baffled “Never had this issue before, it should automatically connect to an Australian network when you turn your phone on”. 2degrees suggest there may be either a fault with my SIM card (cleaned it, visually checked it – looks fine), or the S6 itself (bought new 2 months ago in New Zealand). Any suggestions on what I might do now??? Chat Conversation End. — Hammond

Solution: Hi Hammond. We don’t work for 2degrees Mobile but a quick Google search and you’ll see that their international roaming service should work automatically in Australian networks. We are not 100% certain though if this holds true with your account so make sure that you continue working with them on this one. Third party technicians like us can’t help you in this one. There must be something in their system that prevents international roaming in your device from working.

As far as troubleshooting is concerned, the things that you can try include wiping the cache partition and booting to safe mode only. Below are the steps on how to do them.

How to wipe the cache partition on a Galaxy S6

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

How to boot your S6 to safe mode

Booting in safe mode is meant to check the possibility that a third party app may be causing the issue. Safe mode blocks third party apps and services from running. It’s not a solution it itself but if international roaming will work while it’s on, you should consider uninstalling third party apps individually until you’ve eliminated the problematic app. Here are the steps on how to boot to safe mode:

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

Remember, if both these processes won’t help you at all, contact your carrier again for further support.

Problem #5: Verizon Galaxy S6 unable to receive or make calls after an update

Good afternoon. I have a Verizon Samsung Galaxy S6. Yesterday I was prompted to complete a Samsung software update. I also did one a month ago. After completing the update I was unable to make or receive calls. I would hit send or accept the call and it would just freeze. The incoming caller would hear nothing. if I were to call out, the recipient of the call would receive the call, but would not hear anything on the line when they answered. I tried both incoming and outgoing calls on a landline. On top of that all videos on YouTube, in Instagram, Facebook or Twitter would not play. I would receive a video playback error message this happened on the network and on WiFi. Everything else worked fine received and sent emails, sent and received texts, could browse the internet. I went to Verizon today and they did a factory reset and still the same issues were happening. The manager’s response was to upgrade the phone as there was nothing they could do. I appreciate any assistance or suggestions. Thanks in advance. — Chris

Solution: Hi Chris. If factory reset did not change anything, then the cause of the issue must be due to a coding issue of the latest operating system running on the phone. That said, Verizon must either flash an older but working stock firmware on this device, or simply replace the device. Make sure that you work with them to do any of these options.

Problem #6: Galaxy S6 stuck in boot loop and won’t restart to safe mode

Hi there! I have an issue with my mom’s Galaxy S6. Came across your site and found it very informative. Unfortunately, I attempted all of the advice on several of your articles and still have come up without a solution. I’m hoping you can help before I have to resort to a cell phone repair store.

A few days ago, my mom said that while she was on her phone, it suddenly turned off. She attempted to turn it back on but it won’t boot up past the Samsung logo. Instead, it lingers on the logo for a while as if attempting to boot, then the screen shuts off, it vibrates as if it’s turning off, then vibrates again as if turning back on, and then the Samsung logo reappears. It seems to be caught in a reboot loop that never gets past the Samsung logo.

I found a few articles of yours and attempted different modes to turn it on.

Safe Mode: This is the only mode that has gotten me to any screen besides the Samsung logo. When I tried booting under safe mode, it prompted me with “Warning: A custom OS can cause critical problems…” After selecting “Continue”, it goes into a screen that says “Downloading… Do not turn off target!” and on the upper left hand corner has some of the phone’s information in tiny lettering such as “ODIN MODE” and the phone model. I attached a picture of it just in case if it’s relevant. Nevertheless, I’ve left the phone untouched for a long time, and it just stays in that screen. If I restart the phone, I end up right back in the reboot loop.

Recovery Mode: The only thing that happens when booting in recovery mode is that the words “Recovery Booting” show up in tiny blue letters on the top left corner when the Samsung logo appears. It attempts to boot up for a while, then restarts.

Factory Reset: Nothing happened. It just booted to the Samsung logo screen, then went right back into the loop.

I hope there’s a solution to this. I would hate for her to have to get rid of the phone. It was working perfectly up until 2 days ago, and we can’t afford a new phone for her right now.

Thanks so much for your time and your help.

Best Regards. — Ailyn

Solution: Hi Ailyn. These are the steps on how to boot the phone to safe mode:

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

If your phone won’t boot to safe mode at all and instead direct your to Odin mode, that’s not a good sign. Since factory reset does not work at all, the last thing that you can try is flashing a stock ROM. Doing so will replace the current OS on the device with an official Samsung firmware. If you haven’t tried doing this before, try to do some research with help from Google. An important thing to remember when doing this procedure is to use the correct firmware. Not using the right one for your particular phone model may result to more complications. Our blog does not provide step-by-step tutorial or guide for flashing so try to read as much guides as possible in order to get familiar with it.

Should flashing stock firmware won’t help, we doubt that any technician can help you but you can definitely give repair a try.
