Problem #1: Galaxy S7 “Moisture detected. Make sure port is dry.” error after Android update

Hello. I read an article on your site about the “moisture detected” error message that appears on the Samsung Galaxy S7. I had the same issue happen to me when I tried to charge my phone this afternoon; however, my phone never got wet. I did not put it in water, nor did I touch it with wet hands or splash it with water. I tried a co-worker’s charger, and the error message did not appear; however, I used the charger that caused the error yesterday without issue. The only thing that is different since yesterday is the firmware update I completed overnight. I tried to search to see if any other update-related issues had been posted, but did not find anything similar to what I’m experiencing. Any help/suggestions you may be able to provide would be helpful. Thanks. — Shelby

Solution: Hi Shelby. “Moisture detected. Make sure port is dry.” error usually pops up if the system detects that the charging port is wet. We are yet to encounter a case wherein a Galaxy S7 shows a false alarm like the one you’re having but it’s not far fetched since it’s the operating system that issues such warning. If the phone has never seen water and the error popup started after an Android update, then it’s highly likely that there’s a firmware glitch behind this trouble. That said, doing the basic software solutions may likely be helpful.

The first step that you want to do is wipe the cache partition. This is an important yet simple solution to help ensure that the system works as intended. Sometimes, updates can corrupt the system cache so it’s good to make sure that you wipe the cache partition to force the phone to create a new one. Here’s how it’s done:

  • 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 cache partition.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes’ 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 wiping the cache partition won’t resolve the issue, your next step is to do a factory reset. This will not only delete existing bugs but may also prevent new ones from developing. Refer to the steps below on how to perform it.

Also, it’s important that you ensure that only compatible and updated apps are installed on your phone. Developers are not required to update their products everytime a new Android iteration is released so there’s always a chance that bugs may occur due to poorly coded or incompatible apps. If you aren’t sure if an app is compatible or not, make sure that you check their Google Play Store page for information. You can also contact the developer for direct assistance is needed.

If you are fond of installing third party apps from non-secure sources, make sure that the developer has good reputation. Updating an app can be an easy or resource-demanding duty for a developer so make sure that you only install a good app. Unpopular apps are mostly unprofitable so there’s little incentive for developers in improving them further whenever new Android versions are introduced by Google. Try to stick with mainstream apps for your digital needs in order to minimize bugs.

Problem #2: Galaxy S7 turn on but the screen remains black

My phone is on but the screen won’t turn on. The notification light turns on and so do the back and menu button. I’ve tried holding down the power and the volume down button for 10+ second and the blue light becomes solid (stays on the screen not blinking) then there’s this God awful pop sound. Still doesn’t turn on. I’ve tried the other methods of turning the screen on, nothing. It may also be important to mention i recently had my cracked screen replaced. I didn’t notice until last night that the top of the phone was loose, like the screen would come off. PLEASE HELP! P.S. I don’t know what the version is. — Taylor

Solution: Hi Taylor. You clearly have a screen issue here. Obviously, there’s no amount of software tweaks that you can do to fix a hardware issue. The only resolution available for you is hardware repair. Kindly bring your phone to shop who initially fixed the screen so they can do the job properly this time.

Problem #3: Un-rooted Galaxy S7 stuck in bootloop

Hi. I tried to root my phone using Odin. Everything worked fine until I tried un-rooting my phone. The un-rooting process seemed to be working fine and Odin displayed a success sign indicating to me that the phone was now un-rooted. However, the blue reboot screen with the loading signal wouldn’t appear and it just went blank. Then the first picture with the words Samsung Galaxy S7 Edge appeared with “Powered by Android” at the bottom of the screen. It has stayed frozen on the screen ever since i un-rooted my phone. It won’t reset, I can’t soft reset or do anything with the phone anymore. PLEASE HELP MEEE! — Meihana

Solution: Hi Meihana. The first thing that you want to do here is boot the phone in Recovery mode so you can do a master reset. Below are the complete steps on how to do it:

  • 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 master reset won’t help you, try to flash a stock firmware via Odin. Use Google to search for the correct firmware and guide.

Problem #4: Galaxy S7 won’t boot properly after using SnapChat

Lately I have been having problems with my phone freezing while on app and sometimes getting warm. Last night when I was using Snapchat, the screen went black. I got out of the app and everything else seemed fine but when I kept going back into Snapchat, the same black screen would appear so I powered off the phone. When I turned it back on, the Samsung logo appeared and all looked fine but 5 seconds into it, the phone restarted on its own and kept doing so over and over again. I tried manually turning off the phone and turning it back on but the same thing happens: the Samsung logo appears, the Galaxy S7 logo appears, my lock screen appears and then it vibrates and restarts on its own. What can I do that will NOT delete my photos and videos?

About a month ago I started updating my phone because I didn’t have enough storage before to do the update but ever since I started updating, the phone started to freeze. The phone still looks like new, no cracks, no falls, no water damage, charges great. Hope you can help me, thanks! — Rose

Solution: Hi Rose. An issue like this can be a product of a malfunctioning hardware or by a software glitch. Since you have not much option in this case, try to  check first if you can interrupt the bootloop issue by restarting the phone in safe mode. Here’s how it’s done:

  • With your phone turned 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.

If you’re lucky and your phone will boot to safe mode, the first thing that you want to do is to create a backup of your files. However, if the issue remains and the phone continues to bootloop before or after engaging safe mode, the most likely reason for it is either a bad bootloader or malfunctioning hardware. There’s no way to know which of the two is happening so we suggest that you contact your carrier first to see if they’ve heard of other users experiencing the same issue after updating (assuming you installed an update from them). However, if you got the update from other sources, the problem can be traced on the bad firmware you’ve been using. Contact the developer of the firmware you used to see if there’s a fix they can provide.

If your carrier or the firmware developer can’t provide a resolution, consider having the phone replaced. This means that you will lose your files and there’s nothing that you can do about it.

Problem #5: Galaxy S7 keeps alternating between 3G and LTE signal | Galaxy S7 system time keeps changing on its own

Help! I recently did a factory restore on my Galaxy S7. Shortly after, 3 days or so, I had to refill my service. I Use STRAIGHT Talk which is a problem. My First mistake, The day I refilled my service the LTE would go 3G. So I’d restart my phone, then LTE would work for a minute then BAM 3G again. Then, a day or so later I looked at my phone and freaked out cause it was all the sudden 4 pm! I could have sworn it was barely even 1:30 a little while ago, wtf!?!?!

Well my phone had jumped 2 hours ahead. This problem progressively got worse until I finally said fuck it last night and did another factory restore. obviously that didn’t work. So here it is Sunday morning and I crack my eyes and look at my phone to see the time…FLY up outta bed cause OMG it like 9:47 and how did I ever sleep this late with my 16 month old in the next room and how horrible I am for doing so!!! Then I get her upstairs and the oven says 7:37 (which is still late for us lol) HELP!

I have done

  • hard reset,
  • Soft reset,
  • checked mobile data settings,
  • time and date settings.

I mean if the factory restore isn’t doing it well the fuck can’t wait to hear from you.

Also, do you know how I can update my software? Everything I have found says I’m so because I’m using Straight Talk Thank you. — Amie

Solution: Hi Amie. There may be a third party app that forces the phone alter the system time (and date) without your knowledge. Doing a factory reset will surely fail in this case, especially if you simply install the same set of apps afterwards. Factory reset simply wipes the device

Kindly do another round of factory reset and this time, make sure that you don’t re-install your apps right away. Simply observe the phone (without the apps) for several days so you will know if this issue is being caused by a bad app.

For your signal issue (about your phone alternating between 3G and LTE), we strongly suggest that you seek the aid of your carrier as it may be network- or account-related.

For your third issue, the answer depends on whether or not the phone is originally from Straight Talk. If it is, then the most probably reason why no update is not yet available is because the phone may be running the latest Android Marshmallow version. However, if this phone is originally not from Straight Talk (it may be from other carriers but was enrolled in Straight Talk’s bring-your-own-phone program), then there’s no way you’ll be able to update the phone other than do it manually via Odin. If you want to know more on how to do it manually via Odin, kindly do some digging using Google.

Problem #6: Galaxy S7 Edge camera distorts colors when using selfie mode

When I take a picture using the selfie mode on my Galaxy S7 Edge, I take the picture and it introverts the colors. But when I use wide selfie mode or any of the others it’s fine as well as the rear camera. I’ve never had a problem taking selfies before until last night. You know how there is the little box in the bottom right hand corner showing the last picture you just took? The Colors are fine like a normal picture, but once I open the gallery or click on the little box in the bottom right hand and open up the picture to see it, it introverted the colors of the picture.

Can you please help me? I reset the camera options. What else can I do with out resetting my phone? — Brooks

Solution: Hi Brooks. We’re afraid if resetting the camera options back to default did not fix the issue, the next and only solution you have is to factory reset the device.

But before you proceed with factory reset, try to go over your list of apps and see if you recently installed a third party app that uses the camera in some way. The same is true for other apps that can modify camera functions and can edit photos. Make sure that you uninstall them to see if there’s a difference. Otherwise, simply do a factory reset.
