[Nexus 4 Q&A, Help & Troubleshooting] paul c:
Maybe the difference is like moving from an automatic car (iOS) to a manual (Android).

At least before "multitasking" arrived to iOS, an app no longer in the foreground was effectively exited. Android's memory management is much more complex than that, and apps are kept in memory until a new app requires the RAM being held by a previous one.

There is a clear advantage to this since apps "reopen" instantly, but if you're not careful there could be continued drain from apps still open but not in the foreground.

Incidentally - I don't follow Apple closely - iOS7 has been slated by users for the scenario you describe, I believe!

Google's apps offer all sorts of wonderful location-based features, for which the phone inevitably needs to know its location. Coarse location (via triangulation of radio towers) is not a problem, but "fine" requires the GPS to be used, and that does drain the battery.

So you need to consider whether you want all that location based stuff from Google.

Wifi is also a big drain, and that is why I get my phone to switch on every 10 minutes via DS Battery Saver. The upside is that the phone sleeps regularly, but the downside is that Whatsapp messages etc don't arrive immediately.

As you can see, Android offers you the ability to choose to be uber-connected/always on, or to have a better battery consumption. Since each individual is different, you can choose what is important to you.
[Nexus 4 Q&A, Help & Troubleshooting] Yukicore:
I just had that drain second time happening. I don't remember how I left that stupid game, but I ended up with 2% battery and phone turned off.

I think I exited using the back button. What the hell.

Since it's a virtual pet game the developer probably did not code it to close when you hit the Back button, so you need to kill it through Recent Apps. Or just uninstall it.
[Nexus 4 Q&A, Help & Troubleshooting] Yukicore:
This is bad... Now it is developers fault, but why on earth should Android OS allow this kind of behavior on any app... This is not a simple background service, this was running fully when the screen was off. 2-4 hours is the screen on time averagely I get, 3.5 hours without screen on, it's damn fast draining.
[Nexus 4 Q&A, Help & Troubleshooting] raptir:
We've already been through this. You're fine with your phone's music player running in the background when the screen is off, right? It's the exact same behavior, just that Pou uses more resources and has no reason to be running. Apple puts heavy restrictions on what an app can do in the background (playing music being one of the only exceptions). Google leaves it up to the developer and user to manage it.

If you think that is a problem with the OS, I really recommend you go back to the iPhone. Not being mean or anything, but you clearly either do not understand the differences in philosophy between the two operating systems or you understand it and prefer the iOS way.
[Nexus 4 Q&A, Help & Troubleshooting] Yukicore:
You said that user and developer can manage resources of apps, how can a user manage them? Can I fix this specific problem myself somehow?
[Nexus 4 Q&A, Help & Troubleshooting] raptir:
Yes, by not running apps that are known to be problems.

Edit: And that's one of the key differences. On your Windows computer, not every application you see is safe to run. It could be a virus, or it could degrade the performance of your computer. Since the Google Play Store is not curated to the same degree as the App Store, the same thing applies with Android.
[Nexus 4 Q&A, Help & Troubleshooting] Yukicore:
So there are viruses too? Or just performance degrade?

I do use windows, I am not the apple guy, I prefer more customization, control and features.
[Nexus 4 Q&A, Help & Troubleshooting] eksasol:
There has been a cases of malware in apps in the past, but they were quickly resolved. Apple have their own problem with vulnerabilities as well, especially Safari, no OS is perfect. I do think Google PlayStore can be more stringent and improve on this aspect actually, without making it difficult for developers. Google implemented a virus scanning feature and is turned on by default so you should be alright, just avoid 'sideloading' apk files downloaded from random links. There are still apps that could be spyware (like Gameloft, which ask for your contacts list and location for no reason), but at least on Android you can more control over it unlike Apple, it tells you exactly what permissions are requested when you install the app.

You can install AppsOps, which link to a hidden Android menu where you can turn on and off permissions for apps.

If you haven't, I suggest you do a factory reset, root and use Greenify. Then turn off GPS, Syncing, and Data when you don't need it, which is easier done with ''quick toggles" apps. You can also install and adblock program which can potentially help against junk apps, such as AdFree, or AdBlockPlus which doesn't require root.

You could try battery saving apps like Juice Defender, but I never need to use them myself.

Also it will be helpful if you actually post screenshots of your battery stats screen. Hold Volume Down + Power button to take screenshots.

The Nexus 4 battery life is not great to begin with, if you still want to give Android a chance maybe try something with more battery capacity next time like Samsung Galaxy phones or the newer LG G2, if you can deal with the plastic, even the HTC One have good battery life, and newer devices with Snapdragon 800 chipset should be more battery efficient. Most flagship phones out now have bigger battery capacity than the Nexus 4. With all this said, I can achieve 3.5 to 4 hours of screen on time with my Nexus 4.
[G2 Q&A, Help & Troubleshooting] Grady:
When I plug my phone in to my PC, it always comes up with this "Connected as Installer" Verizon crap. It mounts a disc on my PC. Is there a way to disable this or have it go straight to the MTP storage? I know it goes to MTP after about 15 seconds but that's not the point. Verizon shouldn't force this "installer" every time you plug in your device. I've disabled all of the Verizon bloat already and it still opens a drive that has Verizon installers. I've searched but it seems there haven't been any topics on this yet.

Thanks!
[G2 Q&A, Help & Troubleshooting] shaungregg:
Is it trying to install something on the pc? Maybe just let it install it and it won't do it again, if that's the issue. My T-Mobile G2 asked to install LG stuff when I first connected it and after the 3rd time I let it install and that was that but the LG programs are helpful at least.
[G2 Q&A, Help & Troubleshooting] Grady:
It's trying to install some Verizon Mobile crap that I definitely don't need/want. I haven't found a setting that sends it straight into MTP mode. When it mounts the Verizon Mobile installer, I've tried to delete the contents from the drive on the PC but it doesn't let me. Not sure what else to do. I'm sure every other Verizon LG owner has this happen too...right? RIGHT!?
[G2 Q&A, Help & Troubleshooting] jrgilbert79:
It's a driver installer that you do need...select on the phone what you want or to do.
[G2 Q&A, Help & Troubleshooting] Grady:
Right. I know I can choose what I want on the phone. How do I get it to stop coming up with the installer? I have the driver already.

[Motorola Droid 4] Cannonball3804:
I have a rooted Droid 4 running 4.1.2. I have only flashed a ROM onto a phone once before, on an LG Ally a few years ago. So I'm proceeding cautiously. I've tried to do some research and just confused myself further. I'm just going to post my questions here and hopefully you guys can help. I appreciate it in advance.

1. I don't have custom recovery on the phone yet. It's just rooted at this point. What recovery would you guys recommend? I've seen some references to GooManager -- would that app automate the custom recovery installation for me, or do I need to download Safestrap or something like that to the computer and install from there?

2. Do I have to root again after that?

3. What is the highest current stable version of Cyanogenmod that will run on this phone?
[Motorola Droid 4] kwyrt:
1. I don't know anything about GooManager or if it is compatible with the D4 but safestrap is a really great piece of software that is easy to use. I highly recommend it. Just download and install the app on your phone. Then open the app and install recovery. From there, when you reboot, you will be given the option to boot into safestrap recovery where you can install your ROMs.

2. You will not need to re-root your phone.

3. I am running CM10.2 (Android 4.3) nightlies and have found them to be very stable. I've also heard the latest stable version of CM10.1 (Android 4.2.2) is very good as well.
[Motorola Droid 4] Cannonball3804:
Now I have a Wi-Fi problem

Thank you. I got CM10.2 nightly for 9/28 installed and working. There is only one problem I found so far -- I can't get wi-fi to connect at home. It says it's authenticating, then it saves, then it says there is an authentication problem. I have no problems when I run stock, but it will not work with CM 10.2

I researched online and found lots of people having problems. Some people re-flashed the ROM and it fixed it, others tried this, that or the other and weren't even sure what fixed the problem. Some never fixed it at all.

I did the Wipe/Factory Reset. I re-flashed the ROM. I went back and flashed the 9/27 nightly since 9/28 didn't work. I rebooted my router. I did a Forget on the network and re-added it. My password is correct. I'm at a loss. Not having WiFi with this ROM is like having a great new car that does everything you want except it doesn't do left turns.
[Motorola Droid 4] kwyrt:
Sounds like you have tried most of the things I would have tried to fix it. One other thing you can try: open the Terminal app. Type "SU" and press enter. Then type "wificall.sh" and press enter. That will recalibrate the wifi on the phone. One other thing that comes to mind is I remember some people mentioning when they flashed a new ROM the D4s MAC address got changed which screwed with the wifi connection to their router. I can't remember what the fix was for it, but might be something to google if wifical does not fix it.
[Motorola Droid 4] Cannonball3804:
Thanks for the wifical tip. Wi-Fi is now working at my office. When I get home, I'll see if it did the trick there.
[Motorola Droid 4] herbmillerjr:
Wifi has been hit and miss lately. I had to go back to 9/26 nightly. Didn't have working wifi until 10/2 nightly.

Some of the guys in the development thread found some clues as to why. The must be working on the wifi drivers in the nightlies right now.

[Motorola Droid 4] Huli13:
I just flashed the latest CM (this is my first phone mod) and I working on getting gapps to instal. I have the latest downloaded and am looking for guidance as to how to install the package. This thread looks like a proper place to address that step as it appears to be exactly what you do after you get CM running.

Thanks!
[Motorola Droid 4] rruleford:
Find the gapps for your version of cm and flash like you did the ROM. Usually you would flash the gapps when you do the ROM.
[Motorola Droid 4] iggy_budiman:
1. I prefer safestrap, you can install up to 4 more ROMs in addition to stock ROM. And it's the safest method to try those ROMs

2. That depends on the ROM you are going to install. Most custom ROMs have been rooted already.

3. CM11 that is Android 4.4 KitKat, sweet eh? (correction : CM11 is not stable development yet, but it is latest and nicely working)
[Android Q&A, Help & Troubleshooting] L3r0_H3r0:
I wanted to debrand my Huawei Y210, so I tryed to update from a no brand UPDATE.APP file using download mode, but the process always stopped with an error at the beginning of step 2 (I used the stock update from the official website); then I looked forward to install a custom rom. However, because I'm a true noob, I do not used CWM nor ROM Toolbox (my phone was rooted, my brain not...), but a .bat script I found here to flash the metroPCS recovery.

Obiviously, the script deleted the system, boot and recovery partitions, but when it was time to flash the new system... 83hr23hfhfihryhgnfhksbg! An error occurred:

sending 'system' (154697 KB)...
OKAY [ 38.679s]
writing 'system'...
FAILED (remote: flash write failure)
finished. total time: 55.318s

So now my phone does not have a soul anymore, but it isn't dead at all (I hope so):

The download mode still works and still gives me an error at the beginning of step 2;

The phone is still able to enter fastboot mode (POWER + Volume Down);

When I plug the microUSB cable in while the device is off, it swiches on, starting the charge of the battery. However it does not pop-ups anymore the battery image it appears when the phone is off and charging.

I really cannot understand why the denial of flashing permission... Any Ideas on how to bring my phone back to life?

Edit:

When I rooted my phone the capacitive buttons (Back, Home and Menu) inverted their functions (Home -> Menu, Menu -> Back, Back -> Home): WHY?

However, this is a minor problem...

Does anyone know of a good Movie convertor? I have all my movies already converted on my PC to full size Xvid for streaming to the TV (Pinnacle showcenter) but want ro reduce them down for my exec.

I have always used pocket divx and lathe in the past but can never get the audio in sync.

I have been trialling Pocket DVD studio but the playback is far inferior and choppy compared to pocket divx encoder!
[JASJAR, XDA Exec, MDA Pro General] rayt:
You've got 2 options.

1. DVD to Pocket PC by Makayama Software Tokyo, Japan. Compress 2hr DVD to 128 mb only.

2. Canopus Pro Coder 2 also a good compressor to all formats and media type. http://www.canopus.us/us/products/procoder2/pm_procoder2.asp

I use both of them and very satisfied. All my memory cards were full of Movies or Music.

Hi question...

Coming from a P9 user, so please excuse my ignorance..

Isnt there any need to resize the screen/view? what's the dimension? When i converted movies for my p9 before, i had to make the movie smaller to fit my realplayer.. is there such a thing for Universal? What are the dimensions?

Thanks!!!
[JASJAR, XDA Exec, MDA Pro General] sandgrownun:
The screensize on the universal is 640x480 which is about the same as a 700MB XviD or DivX which may jitter a little and take up way too much storage.

I usually shrink down to 320 x 240 (maintaining the aspect ratio) or even less which doesnt present any noticeable loss of picture quality on such a small screen. For best playback result I use the free TCPMP (formerly Betaplayer) in full screen.
[JASJAR, XDA Exec, MDA Pro General] apple_power:
Try pocket DVD studio, simple easy uses wm codec, so you get good quality. Aslo allows you to output films, fo ppc, palm and other players. Bst thing is it does all the hard work. You can also cover pretty much all files. I have just converted all my south park series from realplayer to my m5000.

And you can resize screen to your hearts content from smartphone to vga size.
[JASJAR, XDA Exec, MDA Pro General] keithchk:
Hi, a quick question about video screen size. I have tried full screen mode on my o2 Exec and the playback is still the same size, with a dark boarder around it, what can i do to fix it? Thanks!
[JASJAR, XDA Exec, MDA Pro General] gooroo:
@keith

I think that for WMP to play at full screen the movie needs to be converted to 640x480 otherwise it will remain at 320x240 even when full screen, I think that betaplayer does not suffer this problem and will expand the movie to fill the screen.

So either convert your movie to 640x480 or change your movie player.

Don't quote me on any of this, I dont even have my Universal yet but from what I have read this seems to be the case.

Regards
[JASJAR, XDA Exec, MDA Pro General] keithchk:
I will try a different player; to convert them into 640X480 will be space consuming... thanks.
[JASJAR, XDA Exec, MDA Pro General] Slave1:
I've had your same problem. I tried resizing videos (with no success).

I now use TCPMP. I can now play avi's and mpeg's in full screen (File sizes are a bit prohibitive though)
[JASJAR, XDA Exec, MDA Pro General] apple_power:
No offence if I can covert a 3hr long bolloywood film to fit easily approx 250mb at vga resloution? How can you not covet 2 hour films in high quality to tiny sizes?

Have you also tried pocket divx?
[JASJAR, XDA Exec, MDA Pro General] keithchk:
Can I say that the scale to fit function is not working for media player? Logically, I would assume that scale to fit means whatever the resolution, stretch it to fit the screen, even if that means quality lost, no? i am not a big fan of converting it to 640 if that means double the size...
[JASJAR, XDA Exec, MDA Pro General] cuteangelika:
Thanks!

Got it now... Im using TCPMP now and it's far superior than WMP. I never did use WMP after I installed this wonderful video player.. It even played smallville xvid... which i cant even play in my laptop without the codecs installed.. :)

Really enjoying this phone.. well, despite of the bugs.. :P
[JASJAR, XDA Exec, MDA Pro General] apple_power:
If you use the right software to encode you can then also then play natively at 640 on your exec.
[JASJAR, XDA Exec, MDA Pro General] sandgrownun:
TCPMP includes Xvid/Divx codecs so it doesnt care what codec was used to encode and doesnt suffer from the WMP screensize problem. IMHO TCPMP is far superior to any other player. If you want a free encoder for your existing movies use pocketdivx encoder. I trialed about 5 commercial products a few months back but didnt have time to post my results. None of them were perfect and pocketdivx encoder produced the best picture/sound quality results but does suffer from time sync issues from time to time.

Its a bit like the cheap £30 asda dvd syndrome. They play anything whilst the top of the range Japanes brands play nothing except retail DVDs :)
[JASJAR, XDA Exec, MDA Pro General] cktlcmd:
I use Pocket DVD Player for Palm, yes for PALM, to convert a movie and use TCPMP to resize it to fit the screen of my O2 EXEC. So basically, I use the 5th setting where the black part on a wide screen DVD is automatically croped out, thus giving a a full screen effect by automatically taking out the black part of the screen found on the bottom and top part of a wide screen DVD movie.

I use the following settings:

Resolution: 464x224 (104kPixel)

Output Size: about 488 MB

Audio: 40 Kbps, 44 KHz, Mono

Video: 464x224, 15 fps

Duration: about 2:08:00

With the following settings I can convert any DVD and play it smoothly with no lags, skips, nor any miss in audio. As you can see, the only drawback is it uses up a huge amount of SD card space, about 488 MB. But I don't care, as long as it is easy and simple. I can easily delete and exchange any movie I want. I can also make the output size smaller, but it causes skips and the quality of conversion is not that good. With the above settings, my EXEC turns into a mini DVD player. :D :D :D :D :D Heck, it made my friends wonder and ask, "where did I bought such a small DVD player?" They were amazed to hear, "Ohhhh it's my phone."

Not only that, since I am using 464x224 size conversion, I can play it on my TH55/E1 and O2 XDA EXEC with one conversion and both running on TCPMP.
