Problem #1: Samsung keyboard on Galaxy S7 always set as default app

I purchased an S7 in March, installed all of the apps above and used all of them with no problem. The phone stopped working in June and being under warranty they sent me a new one.  I reinstalled all of the same exact stuff I had in the first one.  However, in this new phone, Samsung Keyboard continually turns itself back on as default to any app that requires keyboard usage.

I searched the web for solutions and followed steps recommended to turn it off again. I also uninstalled and reinstalled the Swype + Dragon app thinking that maybe it missed a step the first time.  I am still having the same issue with Samsung keyboard turning back on. Everytime I close an app that uses keyboard, upon reopening, I have to go back to settings and turn it back to S +D.  Can you help me to get this resolved?  Thank you for any insight you can offer. — Tina

Solution: Hi Tina. Your issue is probably due to an unknown firmware glitch that forces your phone to switch back to stock Samsung app when doing a certain action, like when need to type something. If you want to use Swype+Dragon combo only, make sure that you clear, then set, the default keyboard app to the one you want. To clear a default app on the Galaxy S7, just follow these steps:

Launch the Settings app from your Home screen or from the app drawer.

  • Tap Applications.
  • Tap Default applications.
  • Tap Set as default.
  • Tap the app for which you’d like to clear defaults. Underneath an app will have two options: None set as default or Set as default.
  • Tap Clear Defaults.

If this procedure won’t change anything, it’s possible that a third party application is creating a conflict with the operating system. Boot your phone in safe mode and try the same steps above. Here are the steps on how to boot your phone 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.

Doing safe mode in this case will not resolve the issue. However, it will help you identify if the problem is being caused by another app you’ve installed. Enabling safe mode prevents third party apps from working so if the problem won’t occur in this mode, that’s a confirmation of our hunch.

Problem #2: Galaxy S7 can’t receive SMS from some iPhone users | Galaxy S7 cannot join group message with iPhone users

I have been an Apple iPhone user for the past 5 years. I switched to an Android two days ago. 

I am receiving some, but not all text messages from iPhone users – this has generally been after they call me and I have asked them to hold down their texts and send them as a text message. I cannot receive group messages or create functioning group messages with iPhones. If I create a group, when others reply, their reply comes back to me as a single message or I do not get their replies at all. 

I have contacted Apple to remove me from i Message. I do not own any other Apple product that could have iMessage activated. I have turned iMessage off on my old device. I have asked my friends & family to delete my old contact and re add me as a new contact so that I am not in their phone as an iPhone…nothing has worked, and I do not have the same SIM card that was in my iPhone. 

I have contacted my provider Metro PCS and Apple and all of the above actions are what I have been told to do. 

Help please.  Almost every person I know has an iPhone and I don’t want to have to switch back to an iPhone just to be able to communicate with them. — Karlee

Solution: Hi Karlee. You’ve already done all the things that you can do on your end to fix this issue. The only problem now is beyond your control as they are on the other side of the equation. Sending and receiving text messages require that both the sender and receiver are on the same page, that is, they must be on the same compatible platform. You need to tell your friends to contact their own carrier for specific guidance on how to send text messages to a non-iPhone device.

For group messaging, you’re certainly out of luck. iPhones only use iMessage  protocol for group messaging, which means non-Apple devices cannot join. This exclusivity is a real pain that’s been going on for too long and may never be resolved. This is the reason why you’ll not be able to get group messages as your friends’ responses will be converted to individual text messages instead. The only remedy for this situation is by asking your friends to use cross-platform messaging like Facebook’s Messenger app, or Google’s Hangouts.

Problem #3: Solution to issues after Galaxy S7 got wet

My phone was dropped in the sea, whilst it function normally for the rest for the day the usual “moisture detected”” notification popped up even though it had been hours since it had been wet.

As advised, I used a hairdryer to ensure the device was not still wet and again began to try to charge the phone. The message still came up and it only started charging once I tried charging in different angles (and it no longer was fast charging, only normal charging).

This worked fine but the next day again “moisture was detected” error pops up again and even when using the hairdryer it would not charge as the message popping up.

As the water was saltwater I assumed salt has been deposited in the charging port as the water has evaporated – using guidance as per the Samsung website, I rinse the USB port with freshwater and more hairdrying time later, again holding the usb charger at certain angles and with added upwards pressure (towards the user), it again normal charged.

Two days later, it then stopped responding to the charger completely – not even a message about detecting water. Hours later and again some angled charging meant that it eventually picked up the charger and charged with intermittent “moisture messages”.

This time however, it only charged up to 70%. After reading your website, I rebooted it safe mode — didn’t actually wipe the cache partition –  and booted it normally. It is now currently charging (81%) but again with intermittent “moisture” messages and only at certain angles.

I have ordered a wireless charging station however using my phone heavily and so charge my phone at work, home and whilst in the car.

Do you suggest to continue rinsing the usb port until all the salt is removed (if this is still causing the problem) or sending it to Samsung for a technician to check it in internally?

Just wanted to know if you think this is a micro USB port issue or if it could hardware/software based? The phone wasn’t in the sea for long, matter of seconds.

issues:

-no more fast charging

-intermittent “moisture detected” messages

-angled charging required

-sometimes not picking up the connection to a charger at all.

Got wet 4 days ago.

Thank you for you help! — Sunny

Solution: Hi Sunny. The “moisture detected” error is there for a reason. It’s a reminder that your phone had been exposed to saltwater (which is several degree worse than regular water) and most importantly, that it needs repair. In an ideal world, you are supposed to immediately remove the battery and dry your phone completely. Keep in mind that the chemical composition of saltwater corrodes the circuit contacts and other metals faster than regular water. Corrosion can set in in a matter of hours so you can only expect bad things to happen starting now.

We know that doing the first one, removal of the battery from the unit, is not advisable and not practical since the said component is integrated with the motherboard. The reason being a connected battery to a circuit will more likely short circuit some components. Doing this is crucial and the longer the battery stays in that phone, the higher the chance of hardware issues to occur. This is the reason why any wet electronic device must be weaned off from its power source right away. Needless to say, turning on the phone while some components are still wet can lead to problems.

The second (drying out the phone) is a must and usually takes some time. There are many strategies in drying out a gadget including putting the device inside a bag of rice. There are other ways to dry out a phone but all of them requires a certain level of disassembly to ensure that all moisture is sucked out. Disassembling your phone, of course means voiding the warranty. You don’t have to be concerned about the warranty at this point though as it’s already been voided when you get the unit wet in the first place. Drying out a disassembled unit takes some time, depending on the conditions it is in. Putting it in a bag of uncooked rice for a few hours then turning it on won’t work, and will most likely result to hardware malfunction. The aim is to let rice or whatever you’re using to absorb the water.  The thing is, you don’t want to attempt a boot up unless you’re 100% sure that the phone is internally dry.

At this time, you can safely assume that your phone is dying, some hardware at least. There’s no amount of software troubleshooting that can fix a hardware problem obviously. The things that you can do right now includes the things below:

  • Save whatever you can. You should be thankful at least that your phone still boots up at this time. That means you can still transfer your personal data like photos, videos, music, contacts, etc., to another device like a computer or SD card.
  • Call Samsung. The next logical step is to make sure that your phone is checked by an authorized repair shop. If there’s a nearby Samsung service center in your area, be sure to let them repair the phone for you. Be ready to pay for the fee though as the repair will definitely not free.
  • Ask for a replacement. You can either contact Samsung or your carrier for this. Although there’s a slim chance that you will get a replacement unit (and you will most likely to pay for it), it’s still worth giving a try.

Again, our point in this brief discussion is to let you know that water damage almost always results to hardware problems. We know that Samsung spent so much in terms of research resources to ensure that the charging port is protected when a user exposes the device to water but in reality, water-resistance in a Galaxy S7 is not perfect. Water resistance on this device has even been questioned lately. Unless you’re a trained professional or makes a living out of fixing electronics, the best course of action is to have the phone repaired. We don’t provide guides how to fix hardware problems so if you feel confident that you can handle the issue, look for guidance somewhere.

Problem #4: Galaxy S7 “moisture detected” error | Wet Galaxy S7 won’t fast charge or charge normally

I have Samsung Galaxy S7 Edge and I putted my phone under water in ocean to take picture. As manual of Samsung Galaxy S7 and S7 edge it says if there is no strong wave going through phone it is okay. That day there were no wave at all and I putted underwater maybe not even a minutes because only to take picture. From then on my charge stopped charging with fast charging. I made sure it is fast charging and fast charging on my phone is turned on.

After 1 day passed I saw the message saying moisture detected. So then I made a lot of research about that and made my phone able to charge but it wasn’t fast charge. I thought fast charge will come back when my USB port is full dried up as my research. Another day passed and now I can’t charge my device at all and saying moisture detected. I putted my phone on rice for 3 days still saying moisture detected. The only mistake I made was that I blew air into the port which I realized after it wasn’t right thing to do. When I shake my phone I can hear some sound which I guess it is water. Now my question is: Is there any way I can fix this problem and will the wireless charge work in this case? — Tom

Solution: Hi Tom. The general rule when dealing with a wet electronics is to have it repaired if it shows problems. The Galaxy S7 is rated as water resistant but not fully waterproofed. Since you’re dealing with problems after dunking your phone in water, you can assume that the device is now suffering from hardware malfunction, much like what Sunny (issue discussed above) is experiencing right now.

Is there any way I can fix this problem?

The answers are provided for Sunny above. There’s nothing much that you can on your end, obviously.

Will the wireless charge work in this case?

Assuming that water damage is only isolated to the micro USB or charging port area, yes wireless charging should still work. We highly recommend that you have the phone repaired nevertheless to avoid having more problems in the future.

Problem #1: Galaxy S7 can’t encrypt SD card | Galaxy S7 takes a long time to read SD card

First of all – YOU DO AN AMAZING JOB HELPING USERS WITH YOUR SITE!!  It’s quite often a life saver, and you don’t allow it to be all jumbled up like android forums – exceptionally well-designed site… so KUDOS 2 U!!

Ok, here we go…

  1. I get scary robot icons and warnings which seem to get progressively worse when I try to go into recovery mode. Note – even with those warnings, it still eventually lets me into recovery mode (at least for now!). 

Specifically, when I first tried to go into recovery mode, the green droid robot was tipping half-way over to the right side (and now I can’t recall exactly – but there was some kind of dotted line going down from his hand or something) …I apologize that I can’t remember because NOW ALL I GET IS A YELLOW TRIANGLE WITH AN EXCLAMATION POINT IN ITS CENTER as I try to go into recovery mode & it’s trying to install system updates. It tries to install updates for 30-45 seconds, then the yellow/exclamation point warning appears, and then it takes me into the recovery mode.  ALSO, after I wipe the cache partition (or whatever I may be doing in there) as I start to reboot the phone from recovery mode, I see some writing flash on the bottom of the screen for a split second and IT’S RED IN COLOR (but it goes away much too fast for me to read it). 

I also get “failed to install security updates” in the notification bar when I’m in the phone as normally being used trying to go thru the “settings” options to try and update.

  1. Is it normal for SD card apps to “load” very slowly after a power-on or reboot?

Specifically, I have a ScanDisk 200GB SD card and it has approximately 50 GB of various apps, pix, videos, documents, blah blah… So when I restart/reboot/start up my phone in normal mode, all the icons that are on the sd card are grayed-out for several minutes.  Makes me very concerned that there is something wrong with the card, the slot (dirty?), or the system.

  1. I am unable to encrypt my SD card – which may be caused by something in the above question?? Regardless, I want to make sure that any issues in the #2 question above are ok or resolved before I try to encrypt my card (if/when possible huh?!!). So after the above is address (for my comfort or my fyi) then how do I encrypt my SD card? Obviously going thru the security menu options isn’t working…

I realized this is rather long, but I wanted to be as specific as possible (hope I was 🙂

THANK YOU IN ADVANCE for looking into these and helping me & likely others out with these Q’s!! — ScottE

Solution: Hi Scotte. First of all, we assume that you did not root the device or install any custom ROM on it. Custom ROM is a user installed operating system that’s not provided by a carrier via over-the-air update. This means that the recovery menu on your phone is still the official Samsung software.

In order to access the stock recovery menu on a Galaxy S7, a user must follow the following:

  • Turn off your Samsung Galaxy S7 Edge.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key. NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.
  • When the Samsung Galaxy S7 Edge 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. NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

If you did these steps initially and was presented with multiple options like :wipe the cache partition” or “Yes — delete all user data,” then you’re okay. If you’re wondering whether the rest of the sequence is normal after the steps above, we say they should be. Samsung’s recovery menu is uniform in all Galaxy S7 devices so we can’t see any problem with the description you provided above.

For your second concern, any device should usually take some time to initially scan a full or almost full 200 GB card after a reboot. However, it should not take over several minutes. The initial scan is necessary for the operating system to identify all necessary files to operate apps but if it takes longer than three minutes to do so, something must not be working properly. Make sure to back important files to another device like a PC and reformat the SD card. This will help eliminate sectors errors that may have developed over time. Remember to always keep a backup of your important data to another device or to a cloud service as even the most expensive SD cards can stop working anytime. Don’t keep eggs in one big basket all the time.

These are the steps to encrypt an SD card in a Galaxy S7:

  • Go to Settings Application.
  • Scroll Down and Tap on the ‘Lock Screen and Security’ Option.
  • Scroll Down and Tap on the ‘Encrypt SD Card’ Option.
  • Then Tap on the ‘Encrypt SD Card’ Button at the Bottom.

If you can’t do these steps for some reason, reformat the SD card first using another device like a computer (don’t forget to create a backup first). Once the SD card has been reformatted, re-insert it to your S7 and attempt to encrypt it again under Settings. If that won’t work, factory reset your device.

Problem #2: Galaxy S7 screen flickering issue

Just about 30 min ago, 4:30 am 7/18/2016, my screen started flickering. it got a thin green line at the top right of the screen. I have to lock and unlock the screen multiple times to see what my screen is displaying. It flickers white and green.

I tried one of the reboots (safe mode one) didn’t work. So I moved on to the second option, and well, screen bugged out. I saw at the top left it said rebooting or something in the top left. And then the entire green went green and it sat there like that till I hit the power key multiple times and started it up normally (kind of).

So I can’t do the 2nd option to reboot. phone is really expensive. and I use it very much for work as I am a pizza delivery driver. I use Google to look up addresses. I don’t wanna use my phone now and get distracted but the lights and get in a car accident or whatever. I really need help.

Phone wasn’t dropped or anything. Screen Is intact though it does appear to be scarred like a digital smear vertically left side of screen.

Any suggestions are very helpful.

I paid a lot for it and take good care of it so anything to help resolve the issue helps. I didn’t buy warranty either because I didn’t think this would happen. Never had this happen before. First experience with a Galaxy phone too. Been great up until now. lasted me 2 months… thank you for reading. any help  is appreciated. — Homero

Solution: Hi Homero. A screen problem like yours can be caused by either a software glitch or hardware malfunction. To identify which of the two is the real issue, we usually recommend that you boot the device to another mode like recovery mode or download mode. Any of these modes runs a code independent from the operating system or apps. This means that if an operating system glitch or app is to blame, the screen should work normally if the phone restarts in recovery mode or download mode. To fix a software issue, we first recommend that you try a factory reset so you can observe how the screen works afterwards. To factory reset your device, simply 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.

If the screen looks exactly the same when you boot in recovery or download mode, you can safely assume that you have a hardware error. You must have the phone checked and repaired by Samsung or its authorized repair center.

Problem #3: Galaxy S7 stuck at Sprint logo screen

I tried to install the new system update to the phone by letting it install overnight on the charger. The next morning, the phone was stuck at the start-up Sprint logo right before it goes to the main screen. It vibrated once, then with a delayed pause, it would vibrate two times. I then proceeded to reboot the system by holding the right buttons and wiped the cache clean and tried to reboot. Nothing happened.

I then had to make the tough decision to do a master reboot, and reset the factory settings. When I did that, instead of getting to the yellow sprint provider logo before the page, it sent me to just the Samsung lettering and vibrated the same as at the beginning. I’ve tried downloading custom OS to the phone, but the downloads go nowhere and appear to be frozen. Battery and initial startup are normal and no signs of battery problems. — Christian

Solution: Hi Christian. Well, there’s really nothing much to do here as you’ve already tried the things a user can do. If a master reset or factory reset sequence can’t be completed, that means that your phone is totally bricked. Contact your carrier and let them know that this problem happened so they can tell their software developer team. Of course, you also want to ask for a resolution by demanding for a replacement unit.

Problem #4: Galaxy S7 Edge not receiving some text messages

Hello! I recently switched from an iPhone to the Samsung Galaxy S7 Edge about a month ago. I have had issues with people receiving my texts and receiving texts from others. I have called AT&T and they told me that my number was no longer associated with the iPhone in their system so that wasn’t the issue. I had all of my friends delete my contact and put it back in and I disabled my number on iTunes. I’m still having issues after all of that. I always receive texts from certain people and they always get mine but others don’t. Sometimes i get their texts and sometimes i don’t. I’ve been on the phone with my service provider three times now and they’re saying that everything on my end is fine. They also said the texts I was sending to these people was going through just fine. I also texted myself and got the messages every time. I’m at a complete loss and this is so frustrating. I appreciate any feedback you can give me! Thank you! — Brittany

Solution: Hi Brittany. Although SMS has become an ordinary method of communication to most people nowadays, the system is not as reliable as it seems. The transmission of SMS still depends in no small part to the reliability of carriers’ message centers themselves. SMS support is still a best effort delivery, which means that carriers don’t guarantee messages will be delivered all the time. Thus, this is an issue that may or may not be fixed by your carrier alone. There’s a chance that the carrier of your friend is having some network issues preventing messages from being sent properly.

For more assistance, we suggest that you work closely with your carrier’s technical support team (not the customer service/billing/sales department) to try to find a solution. There’s just nothing that we can do to help you in this case.

If you want a more drastic solution though, you may want to consider using a non-recycled number or a totally new number.

Problem #5: Galaxy S7 SMS being broken into parts

I made the switch from apple to iphone a month ago and so far I’ve been impressed with everything except texting. It is awful. When i send or receive long texts, it is split up into multiple texts that I have to decode, I’m not even able to receive pictures anymore. I have to use snapchat. I can send them, but not receive. And now, I’m not receiving any texts from my girlfriend although she is getting mine. This is really frustrating because this isn’t the first time this has happened. I haven’t even had this phone that long and already it can’t even do something all phones are capable of, text.  — Josh

Solution: Hi Josh. If your number is recycled, that is, you simply use the old number from your iPhone to your new Galaxy S7, the main reason why you’re not receiving text messages is most probably because SMS from your friends are being sent as iMessage. Make sure that you deactivate or deregister iMessage to resolve the issue.

If you still have your iPhone with you, follow these steps:

  • Put the SIM card you transferred from your iPhone back into your iPhone.
  • Make sure that you’re connected to a cellular data network (such as 3G or LTE).
  • Tap Settings > Messages and turn off iMessage.
  • Tap Settings > FaceTime and turn off FaceTime.

You can also visit Apple’s deregister iMessage website to do so.

For your SMS being split in parts, the best thing that you can you can do is to  contact your carrier so you’ll know if their network allows long messages or not. Many carriers usually follows the old 160-character messaging system. Once an SMS reaches over 160 characters, carriers will usually split them up automatically. This is not universal though so we highly suggest that you work with them for the resolution.
