While my phone was updating it was plugged in by the wall and charging. After the upgrade the battery was drained by the evening, and when I plugged it in to charge again, nothing happened.
- I plugged it into my computer and still nothing.
- I removed the battery and left it out for a few hours and thereafter, tried to charge again but still nothing.
- I switched-off the phone, plugged it in and then I got a battery with a lightning bulb, and it vibrates every 40 seconds or so.
- I left it overnight and it charged to 100%.
How can I fix this problem so that the phone charges while powered on, and gets recognized by my computer again?
