[General Questions and Answers] DanielFFF:
I should start by saying I'm not a developer and not even an Android 'power user'. In fact I'm a complete novice at Android, being on my first-ever smartphone, though I am an electronics engineer with other hardware and software skills.

My Galaxy Gio started freezing on some apps recently, and a factory reset (recommended by Samsung support) made it worse. So, faced with sending it to Samsung, I thought: "Why not give Light Orange a try first, since there's nothing to lose (if it doesn't work, I'll still have to return the phone to Samsung)." I've been unhappy with this phone's speed for a long time (overloaded with apps!), so I'd been wanting to try LO but I couldn't make a backup of the original Samsung ROM and was afraid I might stuff the phone.

LO (build v7) worked (with a new SD card, which was the main problem in the first place, but the stupid Samsung Android OS doesn't tell you that the SD card is not working!), so I'm persisting with it to see if it will fill my needs. It's generally looking OK, but I have one major issue and a number of minor ones. I'm hoping someone here can help with some or all of them. Sorry about the long post - if you don't have time to read it all, I'd appreciate your reading at least to the major issue (point 1) to see if you can help...

1. The major issue is that mobile data doesn't work! In 'Mobile network settings' I have 'Use packet data' and 'Data roaming' both ticked. But if I'm away from home (and thus out of my wi-fi range) I can't get an Internet connection ('No network connection'). In the 'Mobile networks' setting screen, I tap 'Network operators' and it finds my provider, Optus (amongst others). I tap that (or the 'Automatic' selection) and it says 'Registered on network', but I still can't connect. Is there some obscure setting I'm missing? This problem is obviously critical to my overall use of the phone.

2. Given that there is no instruction manual or on-line tutorial (that I could find), and with a number of settings unclear what they actually do, I thought 'Settings/About phone/System tutorial' might contain some help. But it just hangs (Force Close dialogue appears eventually).

3. In Navigon (GPS navigation), the volume buttons say 'Media volume' and the bargraph changes, but they don't change Navigon's spoken directions volume! They did in the Samsung ROM. Maybe it's 'System volume' or one of the others that the buttons should control in this app?

4. Swiping between Home screens, the current screen number is not displayed (unlike in the Samsung ROM). So especially with the nondescript default wallpaper, it's hard to be sure which screen I'm on (until I've populated each with apps!).

5. There are only 5 Home screens in LO (vs 7 for the Samsung ROM). Is this ever likely to be fixed, or must I restrict the number of apps directly accessible via icons?

6. Some of the colour combinations provide poor legibility. For example, in Contacts the person's name is displayed in white on light-grey, which is hard to read! And the tick-box tick colour (in various setup menus) is too low contrast (hard to see if ticked or not). Light green and middle grey are almost the same brightness, and difficult for my old eyes to distinguish.

7. I can't find a way to add name-text for widgets in the notification drop-down (and the function of some is not obvious, to me at least). The Samsung ROM had text under each icon.

8. When I initially searched for a custom ROM (months ago), it was because my phone was bogging down due to insufficient 'internal storage' (whatever that is - EEPROM??). I was lead to believe that most custom ROMs fix this problem by providing 'virtual internal storage' on the SD card. But LO doesn't seem to do this, to allow 'unlimited' apps installations. My storage is again approaching a critical low level. Can anything be done about this?

9. Having changed the home page wallpaper to a photo from the Gallery, how would I change it back to the Light Orange 'default' (if I ever wanted to)?

10. Because the in-built clock doesn't seem to have an analogue display option, I've installed a third-party analogue clock. Is it OK to uninstall the in-built clock app (using Titanium Backup Pro, which can remove system apps), or will this 'break' the lock screen (which displays a digital clock)? Are there any other 'system' apps I should *not* remove (particularly: 'Navigation', since I have Navigon, and 'Music' since it doesn't plays FLACS and I thus use TTpod)?

PS: On the positive side, I'm pleased that the File Explorer has much of the capabilities of ES File Explorer, obviating the need for me to reinstall that!

If you've read this far - many thanks! I hope someone can help with some of these issues. I'm trying to like Light Orange!
