Problem #1: How to unlock a Galaxy S8 if it’s locked with Factory Reset Protection

Hi. Recently I have performed a factory reset in my samsung Galaxy s8 plus but i couldn`t opened it as i forgot my gmail password which i have entered in the first time when i bought the phone. Then i went for bypass it with odin tools. First of all i have flashed with the right combination file. When the factory binary windows came i had enabled the usb debugging mode on and then performed flash with stock rom firmware. Now the problem has arrived. The phone is not rebooting and it`s stuck on samsung logo with LED light on. It is noted that when i flashed with the home cse, it was causing the problem but it was rebooted only when i flashed with the cse. but in that case my gmail is still on the phone that means the bypass has not done. Please help me if you have any idea about that. Thanks.

Solution: Bypassing Factory Reset Protection by flashing no longer works. This glitch was discovered years ago and Samsung has since then patched it. Right now, there are only two ways to gain access to your phone again.

The first option is to use the Google account credentials associated with the device. If the device is currently connected to wifi, which means it is able to access Google servers, you should be able to unlock it by resetting the password for the Google account. You can change your Google account password using another device or computer. Once that’s done, you can then enter the username and password to your S8 Plus.

If your S8 Plus is not connected to the internet or if you can’t  remember the Google account username and password at all, then you must do the second option, which is to bring the device to Samsung. They can use a special tool to unlock the device by bypassing FRP. The process is generally very similar to flashing but the exact method has not been released publicly. When going to Samsung for this purpose, you need to bring the proof of purchase (receipt) and a valid ID.

Problem #2: Galaxy S8 vibrates and shows moisture detected error when charging

Hi. I have a Samsung Galaxy S8. The problem is whenever I connect my phone to the charger, it starts to vibrate and a message comes forth saying unplug the charger moisture detected. It’s been like this for over a month now and I did everything I could think of to dry the charging port, such as cleaning it with a tissue, blow hair dryer in it, etc. I mean if it even was actually wet, shouldn’t it be dried by itself after a MONTH? For how long can water exist inside my phone?! Help me to fix this please 🙁

Solution: Water naturally evaporates after a few hours if you leave the device in room temperature. We don’t think there’s actually water or moisture in the device. The most likely reason is either a bad charging cable or charging port. Try to use another known working official Samsung charging cable and see if that will make a difference. If nothing change, then you can assume bad hardware or charging port is to blame. A problem like this can’t be fixed on your end unless you want to risk a do-it-yourself charging port replacement. We suggest that you bring the device to your Samsung Service Center so they can repair it.

Problem #3: How to fix a Galaxy S8 that turns off by itself

I have a S8 that is around 4 or 5 months old. Recently I’ve noticed that my phone was turned off at random times. Within the last two days it has gotten much worse. Now as long as the always on display is on or if I am using the phone everything functions fine. But if I let the screen lock and it’s in my pocket or if its face down it will shut off and when I turn it back on it’s always at the encryption password screen. I have tried the phone in safe mode I have wiped the cache removed the SD card and all other recommendations I could find and still cannot resolve the issue.

Any ideas on what to try next would be greatly appreciated.

Solution: Try to recalibrate the battery and OS first. Android may not be able keep track of the correct battery levels after running for a long time. Such a situation can lead to random reboots. To check if that’s your case, follow the steps below on how to recalibrate the battery and Android. Here’s how:

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Restart the device.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Another good troubleshooting step to do in this case is factory reset. By wiping the phone and returning all software settings to their defaults, you are potentially eliminating whatever bug that’s causing your phone to turn off on its own. If the cause of the problem is due to a software glitch, factory reset will most likely help. Here’s how to do it:

  1. Create a backup of your persondal data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.
  11. Let the phone run for 24 hours without adding any apps.

Remember, factory reset can only handle software issues. If nothing changes after doing it and observing the phone, you can assume the problem is not fixable on your end. You want to contact Samsung for support if factory reset will not help.

Problem #4: Galaxy S8 can’t detect wifi network, won’t connect to wifi

I am using a Samsung S8 phone with Android 8. I was able to connect to my Wi-Fi couple of days back, but since yesterday I can not ‘see’ the Wifi itself for it to be selected. I am able to see our neighbors wifi and also able to connect to my husband’s phone WiFi. It is only the home WiFi network of ours that I can not see. My husband is able to connect to the same WiFi network without any issues. I have followed all steps mentioned on your trouble shooting page except for Master reset. I have restarted the phone and even cleared the cache partition.

Solution: Try clearing the network settings of your S8 first. This will delete all network configurations like previously connected wifi networks, passwords, cellular settings, VPN settings, etc. This is often effective in fixing all types of network problems. Here’s how to do it:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset network settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

If wiping your S8’s network settings won’t help, do a master reset.
