Hello, please try the following steps in this exact order.
Remove the battery and SIM (if you have on, varies by carrier) from the phone and wait 20 seconds, then, with the battery still out, plug it into your wall charger, then place the battery and SIM back in and turn the phone back on.
If that does not work, then try charging the phone via the USB cable and see if it will charge correctly.
Let me know how that works! There are a bunch of other things that we can try.
If it works, please click Accept as that is how I get credit. If not, let me know and we will keep working on it. Bonus NOT necessary but ALWAYS appreciated!!
PLEASE DO NOT leave Negative feedback! If you need more help PLEASE just reply to this question and I will keep working with you!
Türkçe çevirisi :
1. Sim kart ve pilini çıkar
2. Telefonunu doğrudan prizden şarj eden şarj aletine tak ( pil sim takılı olmasın)
3. Şarj aletin takılıyken önce SIM sonra PİL'i takıver
4. İster bekle şarj uyarısı gelsin istersen açık bakabilirisin.
5. Not : Bu kısımda eğer hala uyarı alırsan ki ben ilkinde aldım telefon kapalıyken, tekrar şarj girişini tak çıkar ve telefonu yüzüntü yada dikey konumda tut ( büyük ihtimalle connectör sorunu vardır servise gidip connectör'ü değiştirtebilirsin
