My LG revolution won't charge - LG enV VX9900 Cellular Phone

my name is Larry and i have the exact same phone. If ur lg isnt turning on and wont charge it could be couple things . either the charging port on ur phone needs replaced and or ur charger has gone bad i would take it to a cell phone repair shop close to you.

Sometimes a phone won't turn on until you have enough charge in the battery to enable this. What I mean is if the battery is so flat, it might take ten or so minutes to start to so a charging state.

If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

I think the following web site has LG products. Please click on the link I found for you to see if you can get the PDF file. If so, it will be free. You can view it on your computer screen or download the file. Hope this helps.

go to menu>setting>phone>date and time>auto time update.restart ur phone

• Keyboard issues (no predictive text):
  • This isn't a "fix" per se, but it seems the best route is to use an alternative keyboard. Swype is pre-installed on the phone, so you can switch to that without installing anything new. Alternatively, you can try other players such as SwiftKey, A.I.type, and TouchPal. Otherwise, LG is aware of the issue and working on a fix.
• Phone won't charge
  • The potential fix is to enable USB Debugging. To do so, head to Settings -> Applications -> Development -> make sure USB Debugging is checked.
  • Alternatively, if it won't charge normally (while powered on), it should charge while powered off. Your best bet is probably to power it off and let it charge while you sleep.
  • For some people, it seems that the phone actually is charging, it just doesn't show it.
• Can't use USB storage
  • Enabling USB Debugging (above) may fix the issue.
  • If not, try uninstalling the phone's USB drivers on your PC. They can be found on LG's Optimus S listing under Downloads ("LG Android Driver").

Unfortunately, there are no perfect fixes for any of the issues listed above. Other users are reporting a smattering of smaller (and substantially less frequent) issues, but hopefully the above can help some people with the most significant issues.
