1. Reposition the phone
The best place for the phone to get charged on the Samsung wireless charger is the exact center. If you’re sure you’ve put the phone onto the exact center but the Samsung wireless charger is still blinking blue and won’t charge the phone, try to move the phone left or right or pick up the phone and place it again on the exact center.
If you’re using a Samsung wireless charging stand, slide the phone from side to side, or even place it horizontally on the charger. You will see the LED light turns blue steadily and then it chargers your phone.
2. Unplug and replug the cable
An unplug and plug-in of the cable is a reset and restart process to the Samsung wireless charger. And this will fix all inner conflicts from the charger itself.
This is the same with the power adapter. You can unplug the power adapter and then plug it in to do a reset and restart to the wireless charger.
3. Use the original cable
There are chances that you have mixed up the cables and use a wrong one for the wireless charger if you have several phones or several chargers from different brands. Wrong USB cables that are cheap or higher-voltage or lower-voltage may stop the Samsung wireless charger from normally working.
Use the original cable that comes with the Samsung wireless charger to charge the Samsung wireless charger. If you’re not sure which one is the correct one, swap out the cable one by one until the wireless charger works.
4. Change the power adapter
If you use a fast charge adapter for the Samsung wireless charger, try to use another wall charger. In our test, a Verizon a36-502a wall adapter works perfectly with the Samsung wireless charger and the phone gets charged again. You can use a 2amp adapter you have around your house, or try an a36-502a wall adapter.
5. Turn off Fast Wireless Charging
If your phone supports Fast Wireless Charging, try to turn this mode off. To do this, go to settings and slide the “Fast Wireless Charging” to Off. To some phones, this option is in the Battery section.
Your phone will get charged in the 5W standard wireless charging mode.
6. Restart or reset your phone
If you believe there is an inner error in your phone, such as a conflict or bug caused by an app (but you don’t know which app it is), try to restart your phone.
You can also try a hard reset, which will also shut off all conflicts and issues from the phone. Then put the phone onto the Samsung wireless charger again.
7. Update or uninstall the app that has problems
It takes a little more time to find out the app that causes the Samsung wireless charger blinking blue and not charging. If you have a few more time, you can close all the apps, restart the phone, then run one single app each time and place the phone on your Samsung wireless charger to see if it stops charging.
Once you figure out the app that causes the charging problem, update it to the latest version or uninstall it.
8. Remove the case or any foreign object
Take off the protective case or any object such as magnetic mounts or cards on the phone and place again the phone onto the Samsung wireless charger. Some sturdy cases are made with PC or TPU materials mixed with metal, which will interfere with the wireless charging process.
9. Turn off the vibration mode
If the Samsung wireless charger charges your phone normally and then after a short time or a long time it starts flashing blue and stops charging, the phone vibration may be the cause. If your phone gets many notifications, it may shift and would not be on the charging area (the exact center).
Replace the phone onto the center and it would get charged again. But the best solution is to turn off the vibration mode, especially when you’re sleeping at night, leaving the phone charged overnight on the Samsung wireless charger.
Turn on the Do Not Disturb mode if you are in this case.
10. Turn NFC on or off
Many users have reported the NFC interfered with the wireless charging process. You can try to turn NFC on or off on your phone to see if the Samsung wireless charger blinking blue and not charging issue could be fixed.
11. Turn Daydream on or off
Same to NFC. If your phone is an Android smartphone, try to turn the Daydream feature on or off to see if the issue could be solved.
12. Fix with the latest version
It’s best to keep your Android or iOS software latest. But if you’ve updated to the latest version over the air and the Samsung wireless charger started flashing blue and stopped charging while you placed the phone onto it, then there should be an update issue over the air.
Find a local official store of your phone and ask the staff to help fix the update version. It needs to download the latest version on to a computer and then install the version to the phone.
13. Cool the phone and the Samsung wireless charger
If you find there is a noticeable warm on the phone during charging, cool the phone and the Samsung wireless charger. You can try to move them into another cooler place. After the temperature goes down, the Samsung wireless charger will work again.
14. Update apps, clear cached partition and reboot

15. Charge on safe mode

Steps of running safe mode are different for different phones. You should refer to the manufacture’s guide to run your phone into safe mode.
16. Send back the charger to Sansung to get a fix or replacement
