After testing the available stock ROMs for the Samsung Galaxy 5 I've noticed a few issues that arise after upgrading from stock Éclair 2.1.1 to FroYo 2.2 which made me stay away from this version for the moment.
I've opened this thread so here you could also write down what issues you've had while using the stock FroYo ROM for your Samsung Galaxy Europa.
5 reasons to not upgrade from stock 2.1.1 to stock 2.2 on SG5 :
1. Compass is broken
: one of the good reasons to stick with 2.1.1 or go with MAD team FroYo ROMs is that stock 2.2 ROM brakes the SG5 compass and all the applications which rely on it (for example the "Satellite AR" app which is useful for displaying the satellites in the sky).
2. WiFi does not wake up every time you unlock your SG5
: one will need to lock and unlock again and again until WiFi comes back from sleep or just tell Android to never put WiFi to sleep. I've also noted that it has some issues connecting back to hidden networks after going to sleep or changing the wireless access points if you have more than one stored in your wireless network settings.
3. WiFi refuses to connect even while using the right credentials
: the issue is more likely to appear if you've switched your phone to Airplane (Offline) mode. It is observed that even a reboot of the device does not fix this issue. The only work around is to switch back to Airplane mode and then switch off the Airplane mode again.
4. GPS is sluggish
: sometimes GPS needs a few minutes in order to lock your position even if you've just turned off Assisted GPS. Using the Fix GPS tip
(FroYo hidden menu could be found by tiping *#*#3214789650#*#*). Sometimes you will need to erase the GPS data to get lock. GPS is just locking slowly on stock 2.2 for SG5.
5. SG5 turns itself off
and there is no way you could turn it back on except if you pull out the battery and place it back in. Sometimes after the reboot I've noticed that it takes forever for my widgets and icons to show again. The only work around for icons never displaying on screen again (yes, even the apps menu is showing a loading beachball of death) was to reset the firmware to factory defaults.
You still wanna go to stock FroYo ?
Think twice or just wait before these issues get fixed in some future releases of this firmware version. I've decided to get back to stock Éclair 2.1.1.
You do not wanna wait ?
Then just switch to MAD Team FroYo ROMs or wait a little bit for subpsyke
to release the final CyanogenMod
