Problem #1: Galaxy S7 Bitmoji has no  Auto punctuate and Auto capitalize options

HI there, My daughter convinced me to install Bitmoji onto my Galaxy S7. Mistake. Since doing so, I have lost some function of the word processor in the Android email app. Specifically, the double space bar to insert a period, and start with a cap is gone. All the setting in Language & Input are set properly. What is peculiar about this is that those 2 functions – double space bar and start with a cap, work in Messages, BBM and any other word processing (input) program / app. I have reset the L & I settings and still nothing in the email app. I have no idea what to try next. You’ll be relieved to know that I have removed the Bitmoji app although the character my daughter set up did look remarkably like me. Any advice appreciated. — Kevin

Solution: Hi Kevin. Each keyboard app (which includes the stock Samsung keyboard, Google keyboard, Bitmoji, among others) has unique features that may or may not be present in other similar apps. For example, the auto punctuate (the one you call double space bar) and auto capitalize are features that Samsung keyboard offers but may not be necessarily available in Bitmoji. If you can’t live without these missing two features in your keyboard, we suggest that you make sure the default input method is Samsung keyboard and not any other else. Just head over to Language and Input menu and tap the Default keyboard section to change the default keyboard selection.

Problem #2: Galaxy S7 Active won’t randomly send and receive SMS and group messages

My friends and I recently discovered this issue with our Galaxy S7 Actives. We are all on the same network and all have the same phones. Our messages are being sent from our side, but are not being received on the other side. We are also all in a group message, and sometimes I’ll be standing right next to my friend and her phone will go off for the group with messages I don’t receive and vice versa. This also happens with individual messages. There is no consistency to the messages I am able to send and receive. Again, they show as sent from my end but aren’t received, or shown as sent to me but I have’t received them. AT&T reset my network, I deleted all my texts, cleared the cache. This happened on a previous Galaxy I had. How do i fix this without having to delete everything, and what causes this? — Sara

Solution: Hi Sara. An issue like this is seldom phone-related so you should work with your wireless carrier to identify the cause. As far as troubleshooting is concerned, the steps that you can do are limited to basic Android solutions like refreshing the system cache, observing the phone in safe mode (to see if a third party app is responsible), and factory reset. These three potential solutions should address whatever phone-related issue there is. If they don’t, you must  continue the rest of the troubleshooting with your carrier. They may or may not be able to pinpoint the exact cause but at least you’ll know that the issue may also be outside their means to resolve. For reference, below are the steps that you must do to perform Android troubleshooting.

Wipe the cache partition of an S7. Updates and sometimes installation of new apps can corrupt the system cache. This, in turn, can lead to apps behaving erratically and slowly. To minimize bugs, regular wipe of the cache partition, where the system cache resides, is recommended. To do this, follow these steps:

  • Turn off the device.
  • Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  • When the device logo screen displays, release only the Power key
  • When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times key to highlight ‘wipe cache partition.’
  • Press the Power key to select.
  • Press the Volume down key to highlight ‘yes’ an 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.

Observe how messaging works while S7 is in safe mode. The next logical troubleshooting step is to see how SMS and MMS behaves when the device is in safe mode. This mode is slightly different from normal mode in that it only allows pre-installed apps to work. This means that if the issue wont’ occur while safe mode is enabled, that’s an indication that a third party may be to blame. We suggest that you let the phone run in safe mode as long as possible so you’ll notice the difference. In your case, a minimum of 24 hours should be good. Make sure that you try to replicate the issue while this mode is still active. Should SMS remains erratic, proceed to the next step. To boot your S7 in safe mode, follow these:

  • Turn your Galaxy S7 off.
  • 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.

Restore all software settings to default. Finally, you should not hesitate to wipe the phone’s storage clean and restore everything back to default should the issue continues. As we’ve said above, this potential solution together with the first two above are the only things that you can try on your end. Just like in safe mode, make sure that you observe how messaging behaves within 24 hours or longer to see any difference. Try to engage your contacts in a group message and normal SMS throughout this period to gain insight into the issue. Also, make sure that you don’t install anything during the observation period. If the situation won’t improve even after a factory reset, contact your carrier for more assistance. To factory reset your S7, follow these steps:

  • Turn off your Samsung Galaxy S7.
  • 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 data / factory reset.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

Problem #3: Galaxy S7 Edge keyboard app not working properly when typing in email

Hello. I have a new issue with my Samsung S7 Edge default e-mail app. I am using two accounts, one from Comcast and one from Hotmail. My Comcast account has accounts strange issue when writing e-mails. The keyboard buttons start to behave strangely:

  1. I cannot double tap space bar to automatically add accounts period.
  2. Frequently, the keyboard will repeat the last button pushed (i.e., I press the #4 button then I press the ‘v’ button resulting in the #4 appearing instead of ‘v’. Once this starts to occur it happens with every button press. It is very frustrating. At this point I have to restart the device. I am using the Samsung keyboard.

Any idea what is happening and why? Also, this is a relatively new issue. I did not experience this issue before October 2016. Any help you can give is appreciated. Thanks. — Jackino

Solution: Hi Jackino. An issue like this may happen if you installed an update or a different app that creates a conflict with the operating system or with other apps. The first thing that you want to try is wipe the cache partition to refresh the system cache. Afterwards, you also want to make sure that you wipe the cache and data of the Samsung Keyboard app. 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 Force Stop, Clear Data and Clear Cache buttons for the application.
  • Tap Force Stop, Clear Cache, and Clear Data (in this sequence).
  • Restart the phone.

Problem #4: Demo Galaxy S7 Edge won’t factory reset and keeps rebooting randomly

Hi there. I received a Samsung S7 Edge phone as a gift. The only thing that I have an issue with this phone is that the device is an ex demo device. I cannot switch over to factory settings, turn on my data, the phone resets itself every few minutes which results to apps being the deleted, phone numbers being deleted and so on. I was wondering if there is anyway of fixing this? I’ve been going through phones like there is no tomorrow and I honestly cannot afford to buy a new one as I’m unemployed. Thank you in advance! — Derbhal

Solution: Hi Derbhal. We don’t know how different Samsung’s demo phones are to regular phones so all we can discuss here will be speculations. We can’t see the reason why you won’t be able to wipe it clean via factory reset but if that’s exactly what you’re experiencing right now, there may be little to nothing that you can do at your end. In the first place, it’s not supposed to be for public consumption, that is, it’s software or hardware may designed slightly differently from regular Galaxy S7s. There may be safeguards in place that enforces some limitations like preventing users from flashing new software to it. To be frank, there’s not much that we can say about demo phones. If wiping the cache partition and factory reset can’t be performed on this device, we don’t think there’s anything still that you can do about it.

Problem #5: Galaxy S7 Edge Bluetooth keeps disconnecting | Galaxy S7 Edge Recent Apps and Back buttons keeps flickering

My Galaxy S7 Edge has become increasingly frustrating. First, it will not consistently allow me to keep my Bluetooth on. Sometimes it DOES work; other times it does not. I have done all of the recommended actions I’ve found on this and various other tech help sites – restarting, clearing the memory, clearing the cache, booting in Safe Mode.

In Safe Mode, Bluetooth worked, so I presumed it was an app issue. I uninstalled all third party apps from my phone and I am still having this issue. Is there any comprehensive list of apps that interfere with Bluetooth, including system apps? Do I *have* to do a system reset? This is always so annoying.

Second, the “back” and “menu” buttons are intermittently flickering on and off quickly. When they are flickering, the phone becomes very laggy, but the screen still works. At other times, the flickering stops and the phone operates like normal. I have not dropped or gotten my phone wet.

Any idea what’s going on or why the phone is doing this? How can I fix it? Thanks for your help! — Ccompton

Solution: Hi Ccompton. No, we don’t have a list of apps that are found to interfere with Bluetooth function in whatever Android phone. If you’ve noticed in many forums and literature in the web, majority of Android troubleshooting does not target a specific cause, or like in your case, a particular app. Almost everything is done to cover a broad range of issue. This is due to the fact that it’s impossible to pinpoint a specific reason for a problem in a complex software environment as Android. That’s why our solutions are more of a trial-and-error and not targeted to any isolated cause like a bug in a code of an app. We also don’t address code-level troubleshooting as that realm belongs to more advanced developers.

The good thing in your case is the fact that you’ve made headway by booting the device in safe mode. That the issue doesn’t occur in safe mode is an indicator that the responsible app or service is not removed, contrary to what you claim. Since there’s no way to know what that app or service may be, we suggest that you do a factory reset. This is the only way to make sure that there are no traces of third party apps or services left in the phone. Keep in mind though that once you re-install your third party apps, the issue may return since you won’t be able to identify the real cause. To minimize the chance of the cause from returning, try to stick with official and mainstream apps only. Try to avoid installing apps from suspect or unknown developers.

For the second issue about the capacitive buttons (Recent apps and Back buttons), the flickering issue may be a sign of a hardware issue. Although there are third party apps (such as Galaxy Button Lights 2 among others) that can control how they behave, random flickering issue is also a symptom of hardware-level problem. Do a factory reset and observe how the buttons behave. If the flickering issue continues, consider having the phone repaired or replaced.

Problem #6: Galaxy S7 Edge stops charging | Galaxy S7 Edge fast charging feature not working

Hello. Thanks for all the helpful information you’ve already posted online. For the past month I’ve started having charging issues with my Galaxy S7 Edge. At first, the fast charging stopped working regularly and i had to play with the charging cable (wiggled it around in the micro USB port) to get it to charge properly. Now, the fast charging feature doesn’t work at all. In the last two days, the regular charge feature starting having problems as well. I would plug in the cable, the charge sound and light indicator would appear, but then would turn off and phone wouldn’t charge at all. Again, I would play with the charger to try getting better contact in the phone itself. Sometimes it worked, others it didn’t. In your troubleshooting post, I read to notice if the phone heated up and emitted a “putrid burning odor.” Mine definitely did this. The phone itself didn’t heat up, but the charger occasionally did where it plugs into the phone.

Also, the smell was strong and obvious. I assume electrical components are burning inside the phone? Is there a way to improve the contacts points on the charger so that, when plugged in, it begins to charge the phone? Or, is it beyond a self-fix at this point and I need to take it in? Thanks for your help! — Craig

Solution: Hi Craig. One of the commonly damaged parts in a smartphone today is the charging port. Either by inherently weak materials, poor design, or user misuse, the charging port issues happen almost regularly. In your case, the symptoms appear to lean more towards hardware malfunction so we strongly suggest that you stop using the device and report the issue to Samsung or to any relevant party (retailer or carrier). The goal is to have the hardware checked.

And no, there’s nothing that you can do on the charger to remedy the situation on the phone itself. You must have the phone checked by a professional. If possible, let Samsung handle the repair so they can advise you whether or not the phone can be repaired economically. If not, a replacement is a better alternative.

Problem #7: Galaxy S7 Bluetooth won’t connect to laptop

Good afternoon. I have a problem with my Galaxy S7. To be honest I am not sure if the problem is with the phone or the laptop. Here is my situation: My original USB cord has been damaged and I can no longer use it. So until I buy a new cord, I am stuck emailing my photos to myself and for the videos I found that I can send them to the laptop via Bluetooth. I have done it quite a few times so I know that it works. But now for some reason, today when I went to try to transfer a video to my laptop via Bluetooth, it didn’t work. I forget the message that was popping up but it would say something like “can’t connect” or something along those lines. Now since I tried this morning, I accidentally removed my laptop from the list of Bluetooth devices that my phone can see. I did a bunch of reading online and decided to try to boot it into safe mode. It didn’t work right away but after playing around a bit, it actually popped back up! So obviously I was very excited. But I should have known I’m not that lucky. Haha. Now when I try to connect it says “Unable to communicate with (my laptop)” I just can’t win with this phone. Please help. — Amber

Solution: Hi Amber. Since you’re dealing with two computers here (your S7 and PC), you will have to do two different sets of troubleshooting for each one. Let’s start by working on your Galaxy S7 first. Make sure to check how Bluetooth works with your PC after perform each procedure.

  1. Clear Bluetooth cache and data. Bluetooth is an app so the steps in wiping its cache and data should be similar to the ones we provide above (refer to problem #3 above).
  2. Install pending operating system updates. Some known bugs for pre-installed apps like Bluetooth can get patches via updates so make sure that you install any available Android updates.
  3. Refresh the system cache by wiping the cache partition. Refer to the steps above.
  4. Do a factory reset. Master reset or factory reset can do wonders. Make sure that you do it to ensure that your phone’s software is refreshed. To check if your phone’s Bluetooth function is malfunctioning, try to connect it to another PC. If it doesn’t work properly on the second PC, consider having the your phone replaced.

For PC troubleshooting, the steps that we provide here are only general ones that targets probable reasons of the issue. These are the things that you must do on your PC:

  1. Restart the Bluetooth radio on and off. This simple troubleshooting may help you so don’t skip it. For some reason, Bluetooth can sometimes fail to maintain connection with another device so toggling the Bluetooth switch on and off may do the trick. If you’re not sure where that button is (it can be a hardware button or a software button), refer to your PCs manual.
  2. Restart the PC. Like toggling the bluetooth switch on and off, rebooting the entire system may be of help as well.
  3. Check if Bluetooth functionality works. You can do this by pairing your PC with a different smartphone via Bluetooth. If Bluetooth works fine on a second smartphone, that means that the issue may be on your Galaxy S7.
  4. Install latest Bluetooth drivers. If your PC won’t connect to a second smartphone either, the next best thing to do is make sure that it runs the most updated set of Bluetooth drivers. Refer to your computer’s documentation how to do this procedure.
  5. Contact your PC manufacturer or software vendor. If the steps above won’t improve the situation, consider asking support from your PC maker or software developer (Microsoft or Apple).
