My motorola droid keeps force closing on Messaging, Home Screen. Gallery ( Which is Rare) and Brower. I use to have a Task killer app i deleted it because of the force closing that was happing and my phone would reboot randomly. I am using an app called Handcent Sms which works better then the Messaging app that came with my phone. I was thinking of doing a hard reset but i don't want to loose my apps or my contacts! Do i need a new phone? I'm also having problems with my battery. I have 4 hour battery and sometimes 3 hour battery which is really wierd.
I think a factory data reset is in order for your Droid, not a hard reset. Do it out of the privacy section of your settings. You may lose your free apps but your paid apps will all be waiting for you in your downloads in the Market. This is a Google phone, you have a gmail account. Contacts are backed up by gmail. You will need to log back into google when your phone restarts.
If you use it a lot you may only have a few hours battery life. Get a battery, another charger like a plug in wall charger to take care of that for you. Use a docking station to plug your Droid in when not in use. All of this can be purchased for around 45.00. The docking station is the most expensive.
