I got a signal the battery was low, and now after charging my phone doesn´t start again??

Leo sounds like your batteries may be low on charge, you can buy a device to charge batteries out of the phone. You may want to buy one charge the battery and try again. also check the contacts on the phone and insure they are not dirty two of them monitor the battery condition. Hope this helps

Check the charging source may be it is not charging properly.

take out the SIM and micro sd and turn on the phone. then shut it off again, replace sim and micro sd then turn back on. DONE! **works on samsung jack too!!!

Charge your phone!! Then it will stop!

try wiping off the connections n hold button down for a min.

buy a new battery

your battery might need to be changed. even if it has a full charger it might not be able to properly charge you phone.
try a new battery.

wont turn on.

It would be helpful to know just how quickly the battery is going flat, and I'm assuming there's no history of the phone having been damaged, but... Try swapping the battery for one from a friend's phone. If that cures the problem, you need to buy a new battery (they don't last forever). Otherwise, try charging the battery fully in a friend's phone using their charger, then see how long it lasts. If this lasts much longer, the problem is that the phone/charger combination isn't charging the battery properly. Mix and match chargers and handsets (mark which are yours before you start, or you will get mixed up) to identify where the problem lies. If the battery isn't old and tired, and the phone is charging it properly, then the problem must be that the phone is drawing excessive current. This could be because you've got it set up to do some power-hungry thing (backlight continuously on, playing MP3s or FM, promiscuously Bluetoothing or IR communicating, etc). Shut down all the functions you don't actually need at the time and see if that makes any different. Once you've eliminated all those, you're left with the liklihood that the phone has a fault which is making it draw excess current. Not good news, but at least you've eliminated all the other possibilities. A.
