Problem #1: Galaxy S6 bluetooth connection issue with Mazdaspeed 3 car kit

Having issue with S6 connection to my Mazdaspeed 3 Bluetooth. I will connect to car no problem. If I call it won’t hear the ringer in car system but only will sound on my phone. Once the other person picks up the call they can’t hear me and I can’t hear them. I will take my phone and remove the connection from phone by hitting the Bluetooth icon from the phone display and hit it again. This will reconnect at this point. I will be able to hear them and they can hear me. I have deleted the pair and re pair again. Same issue. I have disabled the smart lock service and it didn’t help either. I have read about it so much on the Internet but it doesn’t seem to be working. I think 2 upgrade before I didn’t had this issue at all. — Khalid

Solution: Hi Khalid. An issue like this happens many times before in other phones  and bluetooth car systems after an update so yours may not be different at all. There may or may not be software solution to your issue so we suggest that you consider troubleshooting your own phone first. It’s good that you’ve already tried removing pairing and re-pairing it but that may not be enough. You should try other phone troubleshooting to see if they are of any help. Below are the things that you can try.

Delete the cache partition

Forcing the phone to build a new cache is recommended if:

  • the phone is having performance issues
  • apps are behaving erratically
  • the device shows unusual behaviors after Android or app update.

System or app updates can sometimes corrupt existing system cache, resulting to issues, so making sure that the phone is using an updated system cache is highly recommended. Here’s how to do it:

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

Install system and app updates

Another good way to minimize bugs in a system in general is to ensure that all operating system and app updates are installed. Developers release updates for a reason so making sure that you install them is good. If the issue you’re having occurred after installing an update, that’s probably because the software in your bluetooth car kit system needs some updates too.

Unlike smartphones, bluetooth car kits don’t receive software updates often, making many of them lag behind most top-of-the-line gadgets and Android devices. Incompatibility problem is a common occurrence simply because bluetooth car kit systems become way behind in terms of bluetooth connectivity. This is a perennial issue that many car owners encounter time and again, whether they have an Android or iOS phone. It’s not uncommon to hear some people complaining a similar issue to yours immediately after updating their smartphones.

While it’s definitely not the fault users, phone makers nor software developers (Google, Samsung, etc), a lot of people will associate the bugs or glitches to the phone simply because issues usually occur after changes to the device are made. The fact is, the most probable reason can be attributed to the bluetooth car kit too. This means that the current software of the bluetooth car kit may have become incompatible because it’s dated.

As mentioned above, bluetooth car kits don’t receive system updates as often as Android devices so the general direction we want to give you at this time is to check with your car maker if there’s a way that they can install the most recent system update. If they’ll say that there’s no update available for such system at this time, that means that the current bluetooth car kit system was built years before and it’s not designed to support the latest bluetooth features and protocols at this time. You either have to let it stand or simply replace it.

Do a factory reset on your phone

Another good way to ensure that there’s no issue on your phone after an update is to factory reset it. This will not only restore all software settings back to default, but may also eliminate other bugs. To do this, follow these steps:

  • Create a backup of your important files and contacts.
  • 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.
  • Re-pair your phone with your bluetooth car kit without installing any apps yet to see the difference

Remember, if the connection between the two devices won’t go back to normal after a phone factory reset, head over to your car kit system and see if you can also reset its settings to default via factory reset. If you can’t do it, try to seek help from its manufacturer or visit your local car store for assistance.

Problem #2: Galaxy S6 fast charging won’t work

Hello, guys. I have a concern. I don’t know whether the issue I am facing is specific for my phone or is a general Android problem. Here it is: I have an S6 and I am facing this problem: slow battery charging.

There are 2 symptoms that I noticed: 1. When I turn on the screen after starting charging with the screen off, the cell phone stops charging (using fast charger or ordinary one). To continue charging, I have to unplug and plug again and again. I believe the fault is software. But I am not sure about that. 2. About 5 days ago the fast charger (and common charger) is charging very very very slowly. It is not normal. To charge 1%, it takes about 20 min. I ran the Ampere app and realized that the current during charging is between 230 and 260mA. If I am not mistaken, using the fast charger, it should be at 1600 to 1800mA. I realized that fault after a trip. In it I needed to charge the phone in the USB 5V car charger and did not charge properly (same symptom described above).

What have I already done testing? I had a let the battery drain 100%, so that I started to charge. Nothing has changed. I had tried charge using the fast charge that came along with the cellphone and ordinary ones. Nothing has changed. Has anyone had this? Is there any way for me to go and fix it? The cell phone is awesome, although the battery is your biggest con. Without the turbo charger it gets me some doubts regarding if I can still have it.  — Bruno

Solution: Hi Bruno. Hopefully, there’s no hardware issue involved in this case as many times before, an issue like this all boils down to the full functionality (or lack of) the charging port. Logically, since the issue persists after using both fast and normal chargers, the problem can only be phone related. Because there’s no way to know the true state of the charging port, unless we physically remove it from the device and thoroughly examine it, the only to check at your level is to do it indirectly. This is done by trying all software troubleshooting (as software can also cause the issue sometimes). If there’s no positive effect after you’ve tried all software troubleshooting, that’s a clear sign the charging port may be malfunctioning.

Some of the basic software troubleshooting that you can try in this case involves:

  • wiping the cache partition (steps are provided above)
  • observing in safe mode
  • updating the operating system and all apps
  • restoring all phone settings to factory default via hard reset (steps are provided above)

For reference, below are the steps on how to boot in safe mode:

  • Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  • Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  • Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  • 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.
  • Observe how the phone charges.

Remember, if all these software troubleshooting steps won’t change anything, the problem should be either the charging port, or another hardware component. Have the phone repaired or replaced.

Problem #3: Galaxy S6 won’t go out of power saving mode

Hello. The current state of my phone is:

  • Screen is black and white
  • All previous apps are uninstalled besides Facebook

My custom downloaded icons are still there and my home screen and other screens are laid out the same. The options in my pull down menu and gone. I can access settings, but only wi-fi, bluetooth, airplane mode, mobile networks, location, sound and vibration and brightness.

Things I did before it started acting up:

  • Downloaded MaaS 360 app to access my exchange email
  • Encrypted my phone with MaaS 360
  • Put my phone in Ultra Power Saving mode since things have gotten messed up.
  • I uninstalled MaaS 360 and restarted my phone multiple times. While I’ve uninstalled MaaS 360, it still does the MaaS 360 startup with a different unlock visual upon starting the phone up. The process to unlock the phone is pretty much the same, however I need to put my pass code in twice and it starts back up in this “ultra power saving mode” setting with all of the symptoms I described above. — Nick

Solution: Hi Nick. The issue might just be caused by bad system cache we suggest that you delete the cache partition first. Refer to the steps above. If that won’t change anything, do a factory reset. This will force the restore all software settings to their known, working state.

Problem #4: Galaxy S6 battery loses battery power fast | Galaxy S6 won’t charge properly

Hi Droid Guys. I come to your page often to troubleshoot cell phone problems and you guys have always been very informative and helpful. I been having charging and drainage issue with my Samsung Galaxy S6 for a month now. I have tried several of your troubleshoots and most have worked to some extent, but I still have one hurdle that I don’t know what to do about.

History Started out periodically not charging when I plugged it in…hit or miss but usually could get to charge. Then it started not holding a charge and draining real quick. Tried other chargers, same problem.

Did your safe mode trick and it started to charge up just fine and hold the charge. But this only lasted a few days. I don’t have a great deal of apps on my phone (other than what came with it) so thought it was probably an update issue. Updated everything I could, still same problem… still wouldn’t hold a charge and when plugged in would not register that it’s charging.

BUT oddly enough when it was plugged in it will keep its charge where it’s at even when I’m using the phone! So, I did the next step you had which was a factory reset. That fixed the problem of the battery draining. However now I have the issue that it will only charge up when the phone is powered OFF AND even when it’s doing that the symbol with the Battery & Exclamation Point inside appears on my phone. When I power my phone back on, it is charged up and seems to function normal otherwise. But despite what cord I use, it won’t charge the phone (nor do I see the thunderbolt symbol in the battery icon) in the ON position. But it will keep the charge where it was at. Is this a battery issue or a charging port issue? Or something completely different?

PS: I also just saw the troubleshoot to do a soft rest…but that did not fix anything either…actually now that I’ve done that it looks like I’m back to having quick battery drainage issue. Hope you can help! Sincerely. — Michelle

Solution: Hi Michelle. An issue like this can have a software and hardware cause so your first task is to know which of the two is true. Like in most Android troubleshooting, identifying whether an issue is software- or hardware-related is important. In your case, this is achieved by simply doing all software troubleshooting steps. These steps include most of the things we mention above such as wiping the cache partition, observing in safe mode, factory reset, and even flashing of stock firmware (use Google to research more about this step). Don’t forget, if all software troubleshooting and solutions won’t do anything regarding the charging problem, the most likely cause is bad hardware.

The battery drain aspect can also be due to bad hardware (damaged battery). While hardware can sometimes be blamed for losing too much battery power in a short time, at times, software can also be the culprit. If doing all software troubleshooting won’t improve the battery drain situation, you can assume that the battery itself may no longer be working properly. It may have lost significant capacity to hold a charge at this time. This is often true with phones that are already beyond 6 months. This is because of the fact that Lithium-ion batteries, like the one in your phone, can lost last so long. Users can expect to start experiencing battery performance problems after 200-300 charging cycles. A charging cycle occurs when a battery with 0% level is charged to 100% and drained to 0% again. If your phone is at least 6 months old and you charge it once every day on average, it is only normal to notice that the battery may no longer last as long as when you first unboxed the phone. You will now be charging more often everyday. Blame it on chemistry. Battery drain issue is a problem that cannot be fully resolved but there are things that you can try to slow its effects down. Below are some of the things that you can try:

  • Check battery usage section under Settings>Battery to know what apps are eating up power.
  • Uninstall rogue or unfamiliar apps that may be showing high in the list in battery usage section
  • lower screen brightness (to the lowest comfortable setting possible for you)
  • uninstall unnecessary apps (Hint: if there are apps you haven’t used for the last 2 weeks, most probably you don’t need it)
  • Disable or Force close pre-installed apps/bloatware
  • Run antivirus scan to check for malware (malware can sometimes allow for other apps to be installed without your knowledge and these apps may constantly run in the background).
  • Use Power saving mode whenever you can.
  • Factory reset your phone and don’t install any app that may not be very useful to you.

Problem#5: Galaxy S6 “com.android.phone is not responding” error

Hi, My phone has developed serious problems with calls and sounds. It was fine two days ago, but now when I try to make an ordinary call it hangs in the phone app and eventually returns with a message saying that com.android.phone is not responding. When I try to call my number from another phone I’m getting an engaged tone always. However, that’s not the only problem.

Skype and Whatsapp are also failing when trying to make and receive calls and none of the sounds are working on the device. (I’ve even tried using Soundabout to force sounds through the speaker but nothing is happening).

The phone was not subjected to any shocks so I can’t imagine there’s any physical damage. What can I do? Has anyone ever seen this problem before? Please help. — Stephen

Solution: Hi Stephen. There are only two things that you can do on your end for this one — deleting the cache and data of the phone app and factory reset (steps provided above). To do the first one, follow these steps below:

  • 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, look for the Phone app and tap it.
  • 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.

Problem #6: Metro PCS Galaxy S6 does not power back on

It is an S6 through Metro PCS. So the phone had at least half of the battery. Tapped the screen and it lit up, then went black and has had no response what so ever, ever since. We tried multiple chargers, plugged it into a laptop (where it did recognize a device but wouldn’t let me do anything. My laptop thought it was a storage device. It didn’t light up the phone or vibrate or act like it was connected). We took it to three different Metro PCS stores and no one could help. They had us buy a new phone and now we lost all contacts and pictures, everything on the S6 device. It was not dropped, nor did it get wet. And no one can explain it or troubleshoot it.

I’ve had my fair share of phones and carriers but I’ve never seen anything like it before. Of course if we bought the insurance it would’ve been covered through Metro PCS. It’s like it’s a scam! The phone is 9 months old. — Nicole

Solution: Hi Nicole. We’re sorry to hear about your lost contacts and files but if your phone no longer boots normally, or doesn’t respond when you try to power it back on, the most probable reason may be a fault in hardware. To check, try booting the device to other modes to see what you can do. Follow the steps below:

Boot in Recovery mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  • Wait until the Download screen appears.
  • If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  • Use Google to look for a guide on how to do it.

Boot in safe mode:

  • Charge the phone for at least 30 minutes.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Remember, each of the different modes gives you a different approach to resolution. If your phone won’t respond to any of the above button combinations, there’s nothing much that you can do. You must find a way to have the hardware checked or replaced.

We know any of these things are free but if you want to have a working phone, you have no other choice.
