Lock screen lag

how come my lock screen lags when i tried to unlock my phone, it would first freeze then turn black after waiting maybe 15-20sec it would go back to my lock screen where i would try to unlock it again.

Edit:

After resorting and re-downloading some of my apps, some of the apps would just lag out and the camera doesnt seem to function. im on a gt-i9505

[Galaxy S 4 Q&A, Help & Troubleshooting] XxLordxX:
Hi,

Have you tried updating your modem and NON-HLOS?

Hi,

Sorry, but what is "akku"? If you can connect to the charger, then I think (if it's an app or something of sorts) you can configure it from there. Also, I think this app can help you with modding brightness settings.

All the best,

Hi Lord,

thx for your answer.

[Galaxy S 4 Q&A, Help & Troubleshooting] XxLordxX:
Hi,

It seems like a power saving feature. Sorry, but main thread is related to development discussions only, if you have a question, you're on the right thread ;).

Please, try checking for any setting you may have set up that set the phone in power saving mode after you get to 5%, it should be under Settings, Battery, (three dots on right side), Battery Saver Threshold, select "never". When the device gets into power saving mode, it'll do some stuff to, well, extend your battery life, and as you mentioned that after plugging to the charge it comes back to normal, I believe the issue is there.

All the best,

~Lord

I only logged in (my last login is a while ago) to thank [MENTION=2739548]tamirda[/MENTION] and [MENTION=4947202]_alex74_[/MENTION] for their awesome work!

2 months ago i found PhonixRom V10.2 which was the best rom I found so far and was happy with it. Never expected that developing on this rom is going on and I was very surprised to see an update to V11.

V11 is awesome! It looks great and I am really happy with it. Best rom for the S4 I have seen. I know there are a few bugs but I think you two will manage that.

Before I installed the rom I flashed the Bootloder_Modem package and made a full wipe. Everything works great beside the known bugs.

I only had one fc that was not mention yet. I installed the YouTube app in the aroma installer but YouTube didn't work. Deleted it and installed it new from the Playstore and it works fine now.

Thank you for this awesome rom!

Everything was running smoothly until one day my carrier stopped working, well.. at least I can't call or text anyone, and so can't use 3G/4G.

Before this it worked perfectly, but all of sudden it doesn't work anymore. It does say I'm connected but when I'm trying to call someone it says I'm not registered on the network.

I tried testing my SIM on another phone, but it worked perfectly on that one, so no issue towards my SIM.

Hello all,

I am not able to completely get rid of an app by killing it using PhoenixROM killing feature.

[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] rodpp:
Hi there!

To repair the WiFi bug, just edit the file /system/build.prop and change the ro.securestore.support parameter value from true to false.

Regards,

[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Rusty-Island:
Getting there somehow.

Thanks! The graemehill.ca. link was quite educational. It took me a while to figure that the description about an SM-P900 might also apply to my SM-P905 , without breaking anything. After a lot of poking around with Astro File Manager I found /system/build.prop. Then 7Zipper let me read the Text; "179 | ro.securestorage.support=true", but that's all I know how to do, for now. I am assuming that I need to find some kind of text editor. I have a brand new Note 7000 brick, to remind me not to hurry. My old Note 7100 is pimped out after many (idiot proof) ROMs loaded with Odin & TWERP. Actually altering data myself is not in my comfort zone, yet. The Towelroot worked without problems. The Xposed goodies are fine. I am looking forward to flashing TWERP on my Pro. But for now there's no Rom I am confident loading.

[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Rusty-Island:
Write protected /build.prop

On my SM-P905XXUANA7, I rooted with Towelroot, tweaked with Xposed and Nova Pro, backed up with Tinanium and trundrelled along happily for months, preserving my warranty, fantasizing OTA update goodness . Given that Custom ROMs are not forthcoming and OEMs are out to enslave us with the next installment, I protected myself by fusing KNOX with a TWRP installation. After backing up, I flashed "rodpp's : STOCK with SELinux setenforced command enabled". As predicted my WIFI did not work at all. I set about learning how to falsify /system/build.prop, as instructed, so as to get WIFI back. I succeeded in editing the word on the given line in the given file but when I try to save the amended system file back, I continuously get an error. The only way to fix WIFI is to Restore from backup.

How do I adjust the /system/build.prop file? So that I can get on with Linux Mint installation. Can anyone link me to a utility that can get around the write protection?

Part of my problem was implementing Su and Terminal properly. With those tools I am now getting comfortable navigating the rooted file system. I have now implemented [MOD] [905] selinux permissive by esgie, instead; so i no longer need to flash custon kernel and edit my /build.prop to achieve permisive. I am now pursuing chroot : Linux Deploy, fumbling around trying to hook up a distro image to VNC.
