Samsung A505 won't charge. When turned off, when the charging is connected, a circle with a lightning bolt appears. The circle goes out and appears with a frequency of 5-10 s. There is no charge indication. With the charger connected, the phone does not turn on, you must turn it off. I threw a new train original. Behaves the same way, replaced the charging and power controller, can there still be a problem in the battery? Help, can anyone come across
