[Galaxy S Plus I9001 Android Development] Martin_Ro:
Hello Together,

it's quite confusing and also disturbing to read about Bugreports in the different Rom threads because sometimes it is not clear, if it is a rom specific Bug or a "CM base Bug".

So I will now start this Thread to collect the Bugs that are CM-Port related and not ROM related in the big hope it will help the devs to find the source of a bug.

Please only Report a Bug here, that happens on more than one different ROM, so we can see it as CM9 related.

Also please only Report Bugs with "clean" installations, so no "I have Ivendor RC4 with CastegnaIT 6.6 Kernel" because there is no way to find out, if this Bug comes from Ivendor CM9 or the customized Kernel.

Also don't repeat Bugreports "Please no +1 Posts" to keep it clear.

I Will Update Firstpost with Bugs and Solutions frequently.

For now, I observed the following Bugs in

every

CM9 based ROM (ivendor and acro68 Versions and customized version of that):

Bug: "Blank Screen Screen" Bug

Description: The Screen stays clear when opening an Application, no content is visible, also the scroller shows the correct size of area, so it seems as if the content is rendered but not visible

Affected Application : Every Browser (Stock and custom like Boat Browser) and eMail (Stock), different Reader like Google Reader and Facebook. Seems as if every App with a Scrollview is affected (maybe a bug in Scrollview code itself ?)

Workaround : Kill app with taskmanager (also remove from cache) and then restart

Also it seem, that current Version of Maildroid(Pro) is not affected from this Bug, so it's a workaround. Also Mail Sync for Exchange seems to be quite more battery friendly.

Update:

User "kaarl" maybe found reason for the bug: click me and further click

Bug: Wake freeze/slowdown

Description: After phone wakes up (by using powerbutton or by events like alarm or phonecall) it sometimes seems, as if it CPU isn't able to go over Min frequency. The phone don't really responds to touchscreen or buttons, screen mostly stay's dimmed

Workaround : Waiting up to 2min or pull battery out , wait 5 sec. put battery back in restart

Bug: Battery voltage reading seems to be corrupted.

Description : There are readings from 3mV up to 3V, depending on used App (AndroSensor shows 3V at 90% battery what seems a bit way off)

Bug: Faceunlock don't work

Regarding Battery drain with different signals (tested with acro's Beta Build 2 with IMAP all 15min and Whatsapp installed):

3G : 1,5-2,5% / h

WLan : 2,5-4% / h (AVM Fritzbox as WLan Router)

2G : <1%/h !

This values are nearly same numbers as BOKQ6 so there seems no longer an issue with battery !

I found, that exspecialy 3G drain is very much affected by signal strength. In my office I have quite good signal strength and have a drain @3G by around 1,5-2%/h. At home the 3G signal is very poor, it often swaps to 2G, there I have a drain like 7-10%/hour.

On the other side, I have the feeling, that with acro's current Build(Beta Build 2) I have a slightly better 3G signal then with BOKQ6 (GB-Rom) when signal is low. Maybe there is some output limitatation for radio antenna in GB Roms that our ICS Roms don't have ?
