In theory an update should be a good thing and Gingerbread V2.3.5 had listed few good things in its original release in July'11, like:
- Improved network performance for the Nexus S 4G, among other fixes and improvements
- Fixed Bluetooth bug on Samsung Galaxy S
- Improved Gmail application
- Shadow animations for list scrolling
- Camera software enhancements
- Improved battery efficiency
Few weeks ago, I've updated my HTC Desire HD, OTA, to Gingerbread 2.3.5 and since then I have different issues than before (2.3.3)....
The most annoying one is the battery life, was bad before, now totally sucks. Even if the phone just sits there in the pocket or on the table and have only few calls and a quick Internet browse, before I get home is already on red (used to be still on green with similar type of use).
I also noticed that now I'm connected more to GSM instead of 3G, in areas where before I used to have 3G, in this situation Internet experience is almost impossible.
Another one, reboot takes forever and even if you think that it is not that important, could be sometimes. I experienced apps crashing and rebooting every now and then, and had to wait long minutes to get it back.
I think I had enough of these poor quality STOCK ROMS and STOCK RADIO and I will go back to customized (had before and I was happy with it - stupid enough though to come back to STOCK) ones and I will search to find THE ONE that at least gives me a decent battery life and increased signals.
I'll come back with my findings.
