Problem 1: What to do when your Galaxy S7 has water damage
Hi TheDroidGuy. I bought a samsung galaxy s7 refurbished (it was cheap so i was tempted to buy it). i wasn’t sure if it was still water proof so was careful with it but my friend didn’t know it wasn’t water proof anymore. he took my phone to take a video in the water then my phone started to blink and then i was slow (i wasn’t near him so i didn’t know it got water damage). he said the phone went out. i didn’t understand what he meant so i left it. When i came back after an hour, the phone didn’t charge, no charging sign. i got worried so i went to see maybe there is dirt in the charging port. i shook the phone and water spilled out immediately. i checked the internet what to do so i put it in rice for 72 hours, but then nothing. i took it to and expert he opened the phone and clean it but he said the only way is to replace a board but it’s not worth it. So i went home, opened the phone and a saw on the web that you can clean the phone with alcohol and it should fix it. So i did exactly what they said and i put it in rice again. This time opens after 72 hours, still the same but this time after like, 5 minutes of charging the phone was hot. The battery got power. So here is my question: the phone charges but it dosent show an indicator like a light or turning the screen nothing. what do i need to do? Please help me. By the way, sorry for the long email 🙂 — Benayahu Nissanian
Solution: Hi Benayahu. Water and electronics don’t mix. Even if a phone like an S7 is water resistant (it’s not waterproof by the way), the protection is limited and may not always protect the phone all the time. Intentionally dunking your phone in water is really a bad idea. There’s always the chance of water resistance protection failing, just like what happened to your device. Even a tiny amount of moisture can potentially lead to significant hardware malfunction.
Since your phone fails to power back on after it got wet, it’s safe to assume that there’s now a serious hardware problem. There’s no amount of drying or cleaning that you can do now to fix the problem. Unlike other issues, water exposure can result to multiple component failures at once. This is possible especially if the battery is left connected to a wet motherboard and other components. Ideally, you’re supposed to remove the battery right away to minimize shorting components. The longer the battery stays connected in this state, the more likely that components can malfunction. This is most probably the main reason why the “expert” who checked your phone suggested a motherboard replacement. This option is reserved for hopeless cases only, which means that water must have damaged multiple components that replacing a single part won’t make any difference at all. While it’s possible that you’ll still be able to have a working phone after a motherboard replacement, this option is usually impractical since the cost of a new board can cost you at least $200. Add in the repair cost, among other parts like the battery and you’re staring at a minimum of $300 repair fee.
To prevent encountering a similar problem in the future, try to minimize the chances of your device, even if it’s rated as water resistant, from coming in contact with elements. You don’t want to believe on promises by marketing teams of hardware makers. As much as possible, avoid water in your devices unless you’re positive that it’s perfectly okay to do so. Remember, once an electronic device has been damaged by water, there’s nothing much that you can do about it. Cleaning it with alcohol and drying are meant to prevent further damage. They won’t, however, fix the components that already got damage with initial contact with water.
Problem 2: Galaxy S7 fast charger stopped working
Hey I have a Galaxy S7. Just last week my original fast charger out the blue stopped working, it didn’t work on anything else. I started using a regular adapter with no brand and today I bought a fast charger original from my friend who doesn’t use his S7 no more. At first when I tested it his wall piece was working, and it charged my phone on fast charge nicely too. However now as I got home that wall charger isn’t working on my phone or any device either. — Deen
Solution: Hi Deen. We don’t know what exactly you’re expecting from us but you really have a simple issue. If that “new” charger is no longer working as expected, it must have been damaged for some reason. Unfortunately, it’s impossible for us to know what the real reason why that charger has stopped working. A common reason why multiple chargers tend to stop working in one location can be an unstable power source. If you encountered this same issue with your other chargers in the past in the same place where you are right now, there’s a chance your power line is problematic, or your favorite wall outlet provides an unstable voltage. Fixing this outlet or talking to your home power provider should fix the issue.
Problem 3: Galaxy S7 won’t boot to Recovery Mode, stuck in bootloop
Hi. I tried downloading some things using Odin to get my phone to be rooted. Unfortunately, I followed a guy’s tutorial because my phone won’t accept the data on the installment to root my phone “can’t mount data, system.”
So I followed a guy’s tutorial to go to repair and change file system and clicked exfat. As I was doing that, it was stuck on updating partition for 3 hours or so. So I took a leap of faith and hold the power button. As I was downloading the stock ROM for the s7 to reset everything, But it wont let me go to the recovery mode. It’s just stock there with the twrp logo. Now I can’t do anything. I tried using odin to download the stock rom but it fails “can’t open serial(COM) port.” Right now, the phone can only do downloading mode for odin. If i turn it back on it just keeps vibrating with the samsung logo with powered by android boot loop. Any idea what to do? sincerely, Zidan
Solution: Hi Zidan. Modifying a phone’s software sometimes lead to problems. That’s a fact of life. Sometimes, the problem is caused by an incorrect guide, while in others are due to user negligence. Still, other cases are caused by something anyone cannot control like a sudden power failure while flashing in in progress, or even an unknown glitch in a USB port of a computer you’re using. Since there’s no way for us to trace where the problem really lies at this time, the only suggestion we have for you is to try to reflash the bootloader. A corrupted bootloader is sometimes the reason why bootloops or sudden restart symptom occurs. If you haven’t tried it, be sure to do it.
Below are the sample steps on how to reflash a bootloader. Exact steps may vary depending on your phone model so be sure to look for more authoritative guides on how to do it properly.
- Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
- Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
- Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
- Proceed with the rest of the flashing procedure using the Odin program.
- In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
- Now, make sure that the Device Added status and its ID:COM box has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
- Restart the phone once the procedure is finished.
If your phone continues to bootloop after reflashing the bootloader, that’s unfortunate. Try flashing a stock firmware and see if that will help. If it won’t work either, you may be looking at an expensive paperweight.
Problem 4: Galaxy S7 bought off Kijiji does not ask for Google account during initial setup
Just bought an S7 off kijiji and I seem to have multiple issues . During first boot up for example, it did not take me through normal procedures I.e.ask be for Google account, option to sync. I seem to be missing many of the preloaded apps that supposedly come pre installed with this phone. And many other minor things. — Maaz.malek
Solution: Hi Maaz.malek. A Galaxy S7 purchased in North America should ask for a Google account during the initial setup. If you don’t have that, it’s possible that your unit may be fake, or meant to be used in countries that block Google services like China. Contact the seller and see if you can get a replacement phone that’s built for use in the USA or Canada.
