Hello all,
I have had my Samsung Galaxy S2 since the beginning of May and have had no issues. On Monday 18th July I noticed that it no longer sends or receives data when connected in 3G mode. Data is only sent and received when the phone is connected in HSDPA or HSDPA+ mode. I have also noticed that it does not seem to fall back to Edge either, as it used to when 3G or HSDPA modes are unavailable.
I have read on other forums (particularly the Australian Whirlpool forum) that many S2's in Aus have this problem, but have had it from new. My S2 has worked perfectly on 3G for two months and only at some point over last weekend decided it would no longer work.
The symptoms are that when in an area where HSDPA or HSDPA+ (H or H+ respectively displayed by the signal strength meter) are not available, the phone will fall back to the next fastest available connection which is normally 3G. It does this and 3G is displayed but it will not transfer any data whatsoever in this mode. Only when an HSDPA or HSDPA+ connection is available again will it work.
I noticed also that on my usual train journey to work and back there used to be points where the signal would drop back to Edge (E on the display) as 3G was unavailable, but this no longer happens. It seems now that the phone gets stuck trying to pass data over 3G and never falls back to Edge.
There doesn't seem to have been an update to the phone's software and I haven't knowingly changed any settings on the phone, so I am at a loss as to what has happened. The Austraian forums mention disabling HSDPA and HSDPA+ access in the phone with an engineering code fixes it and gives a solid 3G connection, but I'd rather not do this knowing that for the previous two months, the phone has transferred data perfectly in all four modes (Edge, 3G, HSDPA and HSDPA+).
Any thoughts...?
