My mobile phone is Samsung S5660. I charged it directly yesterday. As soon as the charger is plugged in, the mobile phone will run automatically, set automatically and send text messages automatically. It stands to reason that the problem you encounter should be poisoning. I have encountered this problem before, but the serious problem without the landlord is to suggest installing an anti-virus software. Poison or not, poison should be killed frequently. If it doesn't work, it is recommended to repair it, that is, restore the factory settings. If the above method still doesn't work, I suggest the landlord take it to repair it. If it can't be repaired, I suggest the landlord.
