[Galaxy S 4 Mini Q&A, Help & Troubleshooting] csendre:
It sounds like you have an app running in the background which is keeping your CPU busy while draining your battery. Look under the battery menu in settings and you shoudl see which app is responsible for draining your battery. CPU governor reports are more interesting if you are using a non standard one. With f4k's kernel you can get access to more than available in the standard CM12.1 kernel. Either way, some of these governors may also help you keeping your CPU running at lower clock speeds and your battery last longer. Which one is the right for you depends on how you are using the phone. There is a good article on this here.

For gapps the best packages to use are the ones listed by k2wl on the first page

The past few CM12.1 builds are very stable with no or minor issues (I haven't found any actually but a few people reported no sound on outgoing calls). You can safely use 04.25, 04.27 builds (did not try 04.30 yet) and battery life is really good on all of these. Once you find which app drains your battery and freeze it, your problem should be solved.

---------- Post added at 10:38 PM ---------- Previous post was at 10:24 PM ----------

The build you mention should work fine. Try a clean install and also check if your APN settings are correct. If not, you may have to enter them manually.

1. Full clean install:

- Traditional interpretation: wipe dalvik cache, wipe cache, wipe /data (factory reset) and after all this flash the ROM

- "Cleaner" install: all the above, but before ROM install also format /system, /cache and /data (this may erase your internal SD so create a backup first). Sometimes this is preferred as just wiping can leave behind interfering files (although it is not supposed to)

2. Samsung ROM:

- If you did not create a full backup of your original one, than you can download one from Sammobile and flash it with Odin

- If you created a full nandroid backup, just restore it from recovery

Note: It is always a good policy to create a full nandroid backup before any ROM installations

2G / 3G troubles

Hi,

Have tried several CM12 and CM12.1 and since a moment, seems the phone goes back on 2G after some times even if it is set on 3G switch.

To be more precise, it receives 3G (3G or H+) well during some time and when you wake up the phone after a while, it is back and stuck on 2G ??

Seems that switching "Preferred network type" from 3G to 2G then from 2G to 3G again brings back the 3G signal... but still for a while then goes back to 2G again...

(Second SIM card is set as 2G only...)

Has anyone met the same issue already and manage to solve it?

Thanks!

Awsome ROM!!!

[Galaxy S 4 Mini Q&A, Help & Troubleshooting] user9192:
found some issues

Hi there,

I just signed up here, so I am still getting started in the usage and habits at XDA Developer, and with giving (hopefully) useful feedback to custom roms etc..

Please be tolerant if I act like a noob ;)

Some Background:

I use a (new) Samsung GT-I9192 since march2015

never used stock-Rom, started with flashing F4k ROM cm-12-20150302-UNOFFICIAL-serranodsdd

Stock kernel and no gapps, worked very well!

continued with flashing cm-12.1-20150428-UNOFFICIAL-serranodsxx and at the same time changed kernel to f4ktion_lp_2.2.6-eur_3gds (ROM and kernel by F4k)

most of it worked fine, but had much greater power-comsumption and a lot of random reboots (around 2-10/day)

Today i tried flashing [MENTION=943196]k2wl[/MENTION] ROM cm-12.1-20150505-UNOFFICIAL-serranodsdd

i did a full wipe before, still have F4k kernel

no gapps installed, also killed some system apps (CM stock browser >use fennec, CM stock filemanager >use Ghost commander, CM stock email >use K9, CM stock media players >use VLC, fm radio >not needed, wallpapers >not needed)

Unfortunately i still have quite a lot reboots (like 2 in about 6 hours)

if there are any ideas how to stop this - at least not more than once per day - i would really appreciate!

I also found some Issues with DualSim functions. Except Issue 4 they did not appear in the last F4k rom i used (20150428)

1. if SIM-PIN is typed wrong (once), device is blocked >> need to activate/deactivate screenlock to get a new try

2. when restart saved status for mobile-data usage is lost (must decide again which SIM to use)

3. when sending SMS , i can Choose wich SIM to use - Feature not working, selction is ignored, always sent with SIM1

4. when calling, I can choose wichs SIM to use, there is also a checkbox to save the selection which sim is used - Feature not working, selection is not saved - selection of SIM at all is working

so i'd like to get this known to the developer/Community.

I am not sure if this is the right place for it. Please tell me.

If more information to device or used Device/ROM/Kernel/Apps is needed please tell me.

Thanks to all developers for GT-I9192 and community here. Seeing a lot of active people here was the reason for me getting this Phone :)

Good report, welcome to this thread!

It sounds like you are having more issues than you should, latest builds are very stable. When you say you did a full wipe what do you mean by this? Did you do a clean install or dirty flash and just wiped dalvik and cache? When you are switching between two different ROMs the best option is to wipe everything: dalvik, data/factory reset, cache and also format /system, /cache and /data (this may erase your internal SD so create a backup first). Some files sometimes can be left over after wipe and these can cause issues.

Did you flash f4k kernel again after flashing the ROM? Every time you flash a ROM the kernel gets overwritten, so unless you flashed again, you are on the stock CM12.1 kernel now.

Try to wipe and format everything as I said above and then flash the 05.05 build or the 04.25 build (I like this the best so far). If you start with an older one, you can then just dirty flash updates.

Comments on i9192 CM 12.1

Hi all. Just some comments. FYI I am not new to flashing device ROMs, I've been using smart phones and digital devices since windows CE and palm OS.

I recently bought a used i9192 and flashed to CM11 (Android 4.4) as soon as I got it. I flashed to CM12 probably a week or 2 after and have been updating nightlies quite regularly. Currently on 12.1 from 05 May.

Generally happy with Lollipop. I like the quick pull down menu, lock screen etc.

What I have found problematic for me in recent weeks (cannot tell which nightly might have caused this) is the fact data connection doesn't enable when I request it. I am normally on wifi with data disabled, but if I enable data via any menu option it doesn't come on. I sometimes have to disable / reenable the SIM a few times to get the data to be enabled.

When receiving a call the screen often does not wake up and makes the situation very confusing trying to answer a call with the screen asleep.

Oh, and where did the CPU performance option go??

I would say nearly everything else works very well. So thank you!
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] user9192:
I am not so sure about what is meant by "clean install"

What i did with my last update:

1. reboot into recovery

2. wipe data /factory reset

3. Cache and Dalvik Wipe

4. install new rom by choosing the zip from SDcard

5. i'm not sure about that... perhaps installed kernel-zip (see below)

6. Cache and Dalvik Wipe

7. restart

i already did a dirty flash before i guess (with F4k ROM CM12.1 based 28042015 - comming from CM12 Build!)

That was just reboot to recovery, wipe cache and Dalvik, Install ROM-zip, install kernel-zip, wipe cache and Dalvik again and start :)

worked fine, but had really a lot of reboots than

hmm i guess i did NOT format any filesystem... as it could delete SD card i really should get used to backup procedures...

i did not do any real backups before, as i do not have a lot of unique and/or neccessary data on the phone, but killig SD-cards will not be so fine, as I store a lot not really neccassary but useful stuff there)

as you tell me this, i must say, i'm not really sure anymore.

my Phone tells me I do HAVE installed Custom Kernel... so i really can't remember for sure if I did not select that zip (that is still on my SD-card) to be installed...

sorry for that, i'll need to notice this details next time....

that sounds weird to me :-?

if i once did a flash the way you telled - with like wiping everything + formatting some parts - I may use dirty Flash in future for any new builds (i guess must be by same developer and in same CM version - like CM12.1)

sounds like a god idea if future updates become easier.

at the end, I will probably wait to next build to try this...

you may ask why...

hmm, i described several random reboots before, but (maybe some wonder) since yesterday i did not count any reboots :)

just some problems with dual-sim left, , i could life with this for some days....

So I'll try to get some more knowledge about backups, and then try a real clean install with next build...

You should not have less space than with CM11. It happened to me once that for some reason programs and program data got duplicated and I ended with low space as well. Once I wiped

Hi,

Installed this rom yesterday in my GT-I9192, simple great. But I'm missing the stock rom feature that allowed me to see if my contacts where saved in my SIM 1/2 or my Gmail account in the contacts lits, the little icon in the right, also I lost the feature to save new contacts directly in my sim cards, now I only have my local phone account or my Gmail account.

There are any way to get these 2 features from the Samsung rom back? Looked in many Sim Managers and Dialer/Contacts managers in Play Store and none of them can do what I want. The Sim managers simple don't manage the sim in slot 2, completely ignoring it, and the Dialer/Contact managers although see the contacts in both sims don't allow me to save new ones directly in it, only in my Gmail or local phone memory.

Thanks.

I may be wrong, but to my knowledge no CM versions have ever allowed saving contacts to SIM. Why would you even want to do this? It is very inconvenient if you damage or lose your phone, change providers, etc. Having online backup is much better

System profile lock screen issue

Hello,

I've started using version 20150512 and I have now switched to 20150527.

There's still a small issue I'd like to report :

I use a pattern lock screen and I've also set up a system profile that triggers when I connect to my home wifi.

In the profile, if I set lock screen mode to "disable lock screen", everything works fine, but if I set it to "don't ask for PIN or password", then everytime I reboot the phone, this mode won't work anymore. To re-enable it, I have to edit the profile and change the lock screen mode back and forth to this option.

Other than that, this ROM works like a charm!

Been using this CM-12 version for months now, never any issues.

Until I upgraded to the CM-12.1 ZIP; cm-12.1-20150601-UNOFFICIAL-serranodsdd.zip

Since then, very often I get errors of processes being stopped.

So I updated my GAPPS too, to the one supposedly supported for Android 5.1.1 but that just caused a continuous rain of errors saying "unfortunately the process com.google.process.gapps has stopped"

Restore a backup from a few weeks ago.

But now I'm in a boot-loop...

So completely factory reset. And starting new installation of CM12.1 and GAPPS for Android 5.1.1

If i have understood your question correctly, here is the answer:

1. Download CWM recovery version 6.05.1.md5 file

2. Reboot into download mode and flash cwm through ODIN.

3.Reboot and again reboot into recovery mode(CWM) and take a nandroid backup of the stock rom.

4.Then wipe everything and flash cm12.1 .zip file from sd card. Done.

NOTE: A word of caution/advice, it is better to download the stock rom from sammobile and keep it safe somewhere. you never know, if something goes wrong(even if the nandroid backup fails)you can always get back to stock with ODIN. Thanks.

Ever since I setup the corporate email (exchange with permissions and a total encryption of the phone) it keeps giving me FC on gapps and play services.

Moreover I have feeling that system remember APN settings somehow, because even after deleting them or changing settings I still can use mobile data, which is strange.

2) When I define my own Profiles there are only 3 options for Lock Screen behaviour: Leave as is, Disable PIN and Password and No Lock Screen. I'm missing option where the Lock Screen is enabled (e.g. after I disconnect my home network).
