The stock CM kernel (which is included in pretty much every CM based ROM) does have touch boost.

Use Kernel Adiutor to modify settings.
[Galaxy S 4 Q&A, Help & Troubleshooting] Benholder90:
I read that with cm13 the touchboost option will not be there? Do you know about that? When I look in CPU settings in boyh kernel adiutor and ex kernel manager I d read not find any touchboost option
[Galaxy S 4 Q&A, Help & Troubleshooting] Rhoban:
There should be a slider to set how many ms the CPU is boosted when input is detected. Set it to 0.

Friends my 9505 have custom rom gold finger UGNK4 modem and bl (kk base) with philz recovery. I need loli pop stock rom but my pc in under maintenance so can't use odin.i have Flash fire pro version and also loli stock rom file from sam mobile. can I flash through flashfire? its safe?suggest me pls.thanks.
[Galaxy S 4 Q&A, Help & Troubleshooting] Benholder90:
But also I read that that is a different thing to touchboost?
[Galaxy S 4 Q&A, Help & Troubleshooting] Benholder90:
Still, does anyone know if there is any custom kernel for i9505 on cm13?
[Galaxy S 4 Q&A, Help & Troubleshooting] Rhoban:
Somebody told you already that there isn't.

Only JDCTeam ROMs have a custom kernel. So, either switch to those or live with touch boost.

Also, touch boost is not that bad. Without it the UI gets laggy and stutters.

Hi there,

I have a problem with my proximity sensor, when I make a call the screen turns off and it is very hard to unlock it, some times it works by pushing the lock button and after home. I can also 'unlock' by putting a flash light in front of the sensor, so what is the problem...?

Thanks for the help
[Galaxy S 4 Q&A, Help & Troubleshooting] Rhoban:
I would clean the sensor.

Use an app to check if the sensor is working properly.
[Galaxy S 4 Q&A, Help & Troubleshooting] royaleagle13:
When I test the sensor the app tells me that I am at 0cm of the phone...

It is going to be painful to clean the sensor...

Re-Enable Trusted Credentials on Galaxy S4

I have a non rooted, Samsung GS4 SCH-I545, version 5.0.1.

The other day I was kinda bored and skimming though my phone settings. I came across the permissions page and saw a bunch of things from China, Turkey and others that didn't look like they belonged and others I didn't understand languages. So I started deleting them and then ended up just deleting all of them (Tin Foil Hat Moment). What could go wrong, right? Now I can't do anything Google related. App store, Google Account settings, Gmail, etc. I keep getting an error message that says "Check your connection and try again" even tho I'm connected to Wifi or Cell data. I can get to the web through the Samsung browser, but even there I get a Site Security Certificate Not trusted warning.

Searched and searched and asked and asked for a solution, but no answers thus far.

Finally I went to the Verizon store for help. They were pretty busy with the Tablet recall replacements coming in and iPhone 7s going out. The lady looked at my phone for about 5 minutes or so and said she couldn't figure it out but could get me a replacement because I had insurance on it. Been trying to figure out how to re-eneable Google et al since then to no avail. Now I have its replacement up and running, but I want to retrieve those texts, etc from the old one before I wipe it and send it back to Verizon. From what I've been told, there are Apss that'll back these things upin the App Store, but Catch 22, I can't access the App store.

Anyone know how I can restore the Google permissions or whatever I need to do? I can see the certificates (I think they're the same ones, but they're all unchecked now and I don't see how I can re-check their blocks).

I was told to do a factory reset, but that'll wipe all my game progresses, text messages, etc. I could still send and receive texts and phone calls and access some apps. That's what I'm trying to prevent, at least until I can recover them first.

Thanks and sorry so long.

Hi there,

Guys I have a question about modem, Im using MIUI 4.4.4 kitkat based on my I9500, and The phone call quality is horrible, I'm from middle east and since there no 4.4.4 modem for s4, which modem should I use to fix the phone call issue?

I just need a bugless rom with good battery life, I dont care much about some fancy features that lollipop brings to the device, just need battery, miui meets my needs, but except for the bug part.
[Galaxy S 4 Q&A, Help & Troubleshooting] Annunneo:
Flash the latest 4.4.2 modem and boot loader.

---------- Post added at 03:02 PM ---------- Previous post was at 03:01 PM ----------

You could flash a stock Rom without wiping.
[Galaxy S 4 Q&A, Help & Troubleshooting] jb.NY:
I did, but only modem, not bootloader, and the signal went completely off, nor restart or factory reset fixed it, was that because I hadn't have flashed bootloader?
[Galaxy S 4 Q&A, Help & Troubleshooting] Annunneo:
Was it a modem for your country or region, you could try flashing the BL and see if that helps.
[Galaxy S 4 Q&A, Help & Troubleshooting] jb.NY:
Thanks for replying,

yes it was, my region is middle east and i used 4.4.2 I9500_XXUAMDK which they said it was for middle east.

Sadly I couldn't find the related bootloader then , but let me search some more.

Edit:

Tried flashing stock middle east lillipop rom and flashing Kitkat 4.4 miui on it, fixed the call problem, but only one problem still remains, Can't get a fix on my location with GPS, it wont find any satellite... is there any patch to fix this problem?

I would like to know from you all in your experience, which aosp ROM that you have used for i9505 has the best battery life?
[Galaxy S 4 Q&A, Help & Troubleshooting] XxLordxX:
Hi,

There's a battery life sharing thread, you can look at the results, usually they share what's the configuration to get them. Other option would be to look at any battery life screenshot in ROM threads, it varies largely from user to user though, so keep that in mind.

Also, if you're having a very bad battery life regardless of the ROM, I'm afraid that your battery might be old and need replacement. You can easily find them on ebay for around 20-25 dollars I think

All the best,

Samsung Galaxy s4 has locked with lockscreen pin

Hello,

I have forgot the lockscreen pin on my galaxy s4 and have tried many times with all my known pins but no luck. My android is running with lollipop version. I tried all the possible ways to crack that. The following are those i tried.

1. Using android ADM => it doesnt work out because wifi is switched off in my mobile.

2. Using rooting the mobile and applying lockscreen crack patch

but the problem is

**when i tried to flash using ODIN, when i tried to put my mobile in download mode, it doesnt going there. i tried Vol down + Home button + power button(and all other possible combinations). and the warning messages shows Vol up to go to download mode. when i tried pressing Vol Up button. the is no change in that screen

**And while booting mobile using Vol Up + Home Button + Power button, mobile is normally booting

3. Using ADB tool, not at all working because USB Debugger is switched off in my mobile.

4. Using Dr.Fone app, it also requires USB Debugger

5. I also dont have samsung account to reset.

And more to that, i have tried all other options present in the web. no luck..

i have been tried for past 3 days.

Someone please help and solve the problem. I cant loose the phone data also.

Please guys

I assume you have adb drivers and fastboot installed in ur pc. Open fastboot and type in the following Commands one by one.

adb shell

su

mount -o remount,rw /system

cd /

echo "persist.service.adb.enable=1" >> default.prop

echo "persist.service.debuggable=1" >> default.prop

echo "persist.sys.usb.config=mtp,adb" >> default.prop

echo "persist.service.adb.enable=1" >> /system/build.prop

echo "persist.service.debuggable=1" >> /system/build.prop

Flash open gapps through twrp first..clear cache and dalvik cache...if the problem still persists, I would recommend you to flash stock firmware through Odin and then try those Roms
[Galaxy S 4 Q&A, Help & Troubleshooting] DiamondJohn:
You do not "need" to flash the latest firmware. Most people do this so as to have the latest modem & bootloader on their system. And of course, if you flash the latest firmware, you will need to re-flash TWRP.

When installing a new custom ROM. A clean flash will involve wiping SYSTEM, data, cache & dalvik cache

Custom ROMs can have better battery life than stock ROMs.
[Galaxy S 4 Q&A, Help & Troubleshooting] skeedzplaying:
This is how I have done all the time. Flash Rom,Flash Open Gapps, clear cache and dalvik, and boom, restart loop.Even after installing from a stock rom.
[Galaxy S 4 Q&A, Help & Troubleshooting] Rhoban:
Clearing cache and dalvik is not enough. Your are changing systems here, so you have to wipe data and system too.

Suddenly my phone dies when I want to install an app!!

Actually, when i bought this phone it didn't have any problems.

But after i installed a costume rom on it, it faced a problem. frequently it used to shut down suddenly.

So i got tired and installed the official 5.0.1 on it.

But now when i want to install a new application, it suddenly dies.

And i have to put the battery out of the phone and again put in it. otherwise i can not turn it on :(

But while charging it never happens

I am really confused. thank you in advance.

and excuse me if my English isn't good ;)

[Galaxy S 4 Q&A, Help & Troubleshooting] DiamondJohn:
Which ROM and Which GApps are you using?

You may also get more specific help within the specific ROM thread. The ROM threads also commonly have their specific and detailed install instruction including specifying the minimum bootloader/modem & TWRP version etc you need to start on.

That's the problem, every rom I tried is acting like this.I tryied Ressurection Remix, CM13 and other i9515 roms and still this problem.I use Gapps ARM 6.0 Full. Mhmm how do I get the minium bootloader/modem?TWRP 3.0.2-0.
[Galaxy S 4 Q&A, Help & Troubleshooting] XxLordxX:
Hi,

You can't easily downgrade Bootloader AFAIK. If you want to try a different modem you can flash it through Odin downloaded from a sticky thread in general IIRC.

I didn't follow the whole story, but apparently flashing stock ROM failed, can you share the steps you followed to install the stock firmware?

[Galaxy S 4 Q&A, Help & Troubleshooting] Rhoban:
I recommend you to try with a different USB cable and USB port.

Sometimes changing things up makes a difference.

If you are talking about Odin giving a failed message.

If the recovery just doesn't stick, we'll that's a different story.

The only other way to flash recovery is by rooting your device first and then using an app to flash the recovery.

If you take this approach, whatever you do, don't root with KingRoot. It's not a very reliable root method.

It's always best to wipe data if you want to avoid problems.

Does anyone know how to fix this? I installed Albe95 S6 keyboard with this ROM, and the keyboard doesn't seem streched. To me, it looks as if Darklord didn't resize the DPI of the ROM. Any help would be appreciated, because I like S6 keyboard more than the one on S7.

Here's the link for the Albe95 keyboard that I use: https://mega.nz/#!eoIgBQJL!JfHXFpbH2...9SUJQcdJ2HuYBE

Note: My phone is Samsung Galaxy S4 Active Lte-A SHV-E330L (but I think it doesn't make a difference?)

Fixed by changing DPI from 420 (which was ROM default) to 480. Now the keyboard fits fine, but I'm not sure if I'm going to have lower fps?
[Galaxy S 4 Q&A, Help & Troubleshooting] Rhoban:
I believe 480 is the original DPI the phone was meant to work with.

Correction, it's PPI, not DPI. Seems that DPI refers to a printed image, whereas PPI refers to a digital screen image.

Anyway, the ROM I'm using has ro.sf.lcd_density set to 480 in the build.prop.
