Problem 1: Galaxy S7 edge won’t charge, showing moisture detected error

Dropped my Samsung Galaxy S7 edge in the sea. The phone did not shut down. Took pictures after it dropped in the water too. working fine but just not getting charged. it says device moist. did keep the phone in the bowl of rice last night, tried charging today morning. still the same message i.e., device moist. – Deepriya Kaflay

Solution: Hi Deepriya. If your S7 won’t charge and keeps showing “moisture detected” error, it means that the system is detecting that there are still traces of water or moisture in the charging port. In order to prevent damaging the device, your S7 won’t charge unless the moisture is gone completely. If gently shaking the device won’t get rid of whatever moisture is left in the port, put it inside a bag of rice again, seal the bag, and place it near a heat producing device like the back of a TV or computer. The aim is to apply very low indirect heat around the bag to allow moisture to evaporate or be absorbed by rice. Do not apply direct heat to the phone or to the bag; direct heat will damage the device. Leave the device in that slightly heated bad for 24 to 48 hours.

Alternatively, if money is not an issue, you can bring it to a service center that fix electronics so they can dry the device using a professional tool. This process will take somewhere around 20-30 minutes.

Problem 2: Galaxy S7 not responding, won’t power on

My galaxy S7 is completely dead. When i put it on charge, there’s a battery icon with a lightning bolt that shows up. this icon will not go away unless i unplug the phone. There is no red LED indicator of it charging nor the green ‘dot’ at the bottom of the screen. also no battery percentage.

I have tried 7 different chargers with 3 different plugs, all of which are fully functional with other devices. Only 1 wire and 1 plug are strangely remotely working with the phone. I borrowed the official Samsung charger for a few hours off my friend and i am still getting the same result. i do not want to sell/send the phone to be repaired as they reset the phone. i do not want to lose the very personal information on this device. Also i do not know the ‘android version.’ — Cairns2009

Solution: Hi Cairns2009. Sending your phone in, just like when bringing your only car to a shop, can be an inconvenience. However, there’s really not much that you can do in both cases. If your S7 no longer charges or powers on, that can mean there’s an on-going hardware failure. The causes can range from faulty charging port, bad battery, or a more serious unknown motherboard failure. Identifying the real issue requires that a technician check the phone physically. Unfortunately, you’re also right, repair will most likely result to losing your personal files and customizations. If you want to get to the bottom of the issue though, you should have it repaired.

Problem 3: Galaxy S7 overheating and not responding, won’t turn on or off

Yes i got an issue with my phone like i forgot my password and i couldn’t factory reset and stuff so i gave it to a new by shop and later they did it. It was fine just that i couldn’t upgrade my phone at all. So today after a week suddenly now my phone is over heated badly and now it’s just not switching off or on. — Siddyjojo

Solution: Hi Siddyjojo. So what exactly did the shop did to allow you to use the phone again? If you don’t know, we suggest that you ask them as that might shed light why your phone is behaving the way it is right now.

In the meantime, you can either try to wait until the phone drains the battery completely, or force to restart it by doing a soft reset. To do that, just press and hold the Power and Volume Down buttons for at least 12 seconds. That should restart the device. If that won’t happen, just wait for it to use up all power. Once that happens, charge the phone again and reboot it to Recovery Mode. This will allow you wipe the cache partition and do a factory reset. If the cause of the problem is software-related, factory reset might help. Otherwise, just bring the phone back to the shop that fixed it initially and let them figure out the cause.

For reference, here are the steps on how to boot your S7 to Recovery Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. You can either wipe the cache partition or do a factory reset when in this mode.

Problem 4: Galaxy S7 freezing, won’t respond

Ok, so after completing the security/system update my Samsung account was having sync issues. Since i forgot my Samsung account password, i clicked i forgot my password. It brings up the account.Samsung.com starts loading the page. it’s frozen. WILL Not respond at all. — Kcole7812

Solution: Hi Kcole7812. If the phone is not responding at all, make sure that you try a soft reset first by pressing and holding the Power and Volume buttons for 12 seconds. If you can’t restart the phone this way, you can then try to wipe it’s cache partition to refresh the system cache. Here’s how:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

A cache partition wipe is usually followed by a factory reset if the issue persists so don’t hesitate to do that. To factory reset your S7, follow these steps:

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings and then touch Backup and reset.
  3. Tap Factory data reset and touch Reset device.
  4. If you have screen lock feature turned on, enter your password or PIN.
  5. Touch Continue.
  6. Tap Delete all to confirm your action.

Problem 5: Galaxy S7 stops working after failed flashing procedure

I updated my phone by the help of software name (ODIN) . In this software, I got options “Auto restart,” “Remove partitions,” “Clean everything /format.” I checked all the option and I connected my phone with PC by USB cable. I put my phone on update mode by pushing volume down key +home key + and power key. After 20 minutes on the pic screen uptake successful, then my S7edge smartphone get offed and never get on again, even if I put in the charge. doesn’t show any light … Seems completely dead, I tried safe mood, everything possible by pushing keys for different purposes. — Iqbal

Solution: Hi Iqbal. This is exactly one of the main reasons why Samsung does not recommend users tamper with the software. There are a lot of things that can go wrong when modifying the official software and unfortunately, there’s no easy to know where the problem lies. Sometimes, the steps in flashing or updating via Odin can vary depending on your phone model. One wrong step and you’ll end up with a bricked device. We suggest that you contact the source of the flashing guide you’re following right now and let them trace which step caused the problem. We can’t do it for you since we don’t have the complete details.
