Hi,John. Thank you very much.
And I compared to other phone whose wifi works well,and found that:
mine:
cat /proc/meminfo
MemTotal: 92436 kB
MemFree: 4636 kB
other:
MemTotal: 199664 kB
MemFree: 2888 kB
*By the way its logcat also includes these:*
*D/ConnectivityService( 1409): Dropping ConnectivityChange for WIFI:
CONNECTING/AUTHENTICATING*
* So I don't think it is the memory.Any more ideas? I have been bothered
by the problem for 7 days.Any suggestion will be appreciated!
* Here is its full logcat:
