Here goes...
1) I download htc sync but it doesn't find the mobile ( i have done this on both the laptop and desktop to no avail) i have used the tips on their site making sure the anti-virus software isn't on etc but still nothing. really would like to get this sorted so i can root it.
This fixed HTC Sense for me:
- Reinstall Locations app
- Remove and re-added your HTC Sense sync account (same user details)
- Sync all
- Untick Phone Finder in Locations and sync all
- Tick the above and sync all again
2) battery life I'm guessing if i am able to root it i'll be able to adjust the settings and delete certain items? I've already sorted out the syncing of facebook emails etc but it still doesn't last that long a day if i'm lucky has anyone got any other tips?
You don't need root access to improve battery life. Here's a few tips:
- Set screen brightness to auto
- Reduce sync times (four hours for Facebook etc)
- Disable Bluetooth, GPS etc when not needed (obvious)
- The biggest one: disable 3G/wifi when not needed
I've only done those and I easily get 2 full days if I don't have 3G on during work hours.
3) Got my sister one and for some reason when ever she answers her phone it instantly goes to loud speaker i cant work out how to get it back to normal and don't know whether its a setting or just the phone.. (it didn't happen for the first week)
No idea, sorry! Try turning "Flip for speaker" off and see if that has any effect.
4) And finally again on my sisters phone the phone lags and when i try to use advanced task killer pro it takes about 30 seconds to get into it and then it needs a force close so no apps can be killed anymore. So i uninstalled it and downloaded and installed it again with the same problem.. Because of this and the above fault could it be a dodgy handset?
Do NOT use any kind of task killer app. They cause more problems than they solve and drain battery life (remove any task killer app from your phone too). Let Android manage the background processes. As for the lag, try turning USB debugging on (Applications -> Development -> USB Debugging). It's a known issue with the latest OTA update.
PS. I assume you both have all the updates? To check go to About phone -> System software updates.
