I'm modding a battery-free android phone but I have some problem ?
Sorry for my bad English :)
I have an old Android phone and I want to use it without battery inside, so I do a little mod based on diagram in the following picture. Everything works fine but I have some problem, when I unplug the 5v adapter from wall socket and plug it back in, I can't turn on the phone using phone's power button. Only when I disconnect the battery circuit from the phone and reconnect can I turn it on using power button. What's wrong here ? Sometime I need to unplug the adapter but i don't want to disconnect the battery circuit from the phone :(
Thanks for your help :)
