I have a peculiar problem with my android handset:
It is a Samsung Galaxy S plus (i9001) .. not exactly an S2
Phone works beautifully, but when Data packet is OFF.
To use google maps/ internet, I switch on Data Network Packet,
but then apps like google maps/ browser only work for a few seconds.
When using the browser, the app stops and I get returned back to home screen (as if I pressed the home button)
From the home screen, I can launch the app (eg. browser) I resume browsing from the same place or page.
but then again I am returned back to home screen (again and again)
I suspect a memory or hardware problem (which occurs only when data packet network is ON)
My handset is still in warranty so not able to try something like root.
I tried by switching the SIM card but still the problem continues.
(I am using 2G)
I am attaching a video so as to explain the problem better.
(in .zip format as .I could not attach the .wmv ),
In anticipation of some help.
