Is Android 4.4.3 KitKat the solution to the bugs of Android 4.4.2? The answer is a mixed bag.

Have you gotten your hands on Google’s latest in Android 4.4.3 KitKat? The update is slowly making its way to Nexus and Motorola devices at the moment and provides a new dialer, and some changes to the contacts list (creating more of a Gmail redesign). Android 4.4.2 KitKat brought problems such as camera app crashes, Bluetooth connection issues, and, of course, the never-ending battery drain problem. Sony just sent the Android 4.4.2 KitKat update to its customers a few days ago, and already, some of our readers are experiencing battery drain.

The Android 4.4.3 KitKat update was meant to fix Bluetooth connection and Wi-Fi issues, improve the Nexus 5 camera autofocus, as well as audio quality and dropped calls. Experienced Android users are also noting that the mm-qcamera-daemon bug in Android 4.4.2 KitKat still exists in Android 4.4.3 KitKat, so Google’s likely got another update to Android 4.4 KitKat that’s still in the works.

If you’ve not yet received the update as a download, you may want to wait. There are a number of problems with Android 4.4.3 KitKat, random problems that range from LTE/3G signal issues to dropped calls, app crashes, and major battery life drain.

Some cases are isolated, such as the Google Play Store app crash one user noted in a forum posting. Others are more common, such as 3G and LTE data problems along with phone signal and reception issues. In one Google forum posting, a commenter said that he’s struggling to get 3G on his Nexus 4. In another site forum, a user said that his Sprint LTE was now struggling to stay on LTE (on an unrooted device at that). Others are noting problems with AT&T data as well – suggesting that the LTE data problem is related to the Android 4.4.3 KitKat update and not issues with Sprint or AT&T.

As for the battery drain, a number of users are experiencing this issue – which isn’t surprising (at least to Sony and some Samsung customers who had issues with their Xperia Z and Galaxy S4 models with the 4.4.2 update). In some cases, clearing the cache helps; in the majority of cases, it doesn’t, even after the users follow the instructions to clear their cache. One user notes his frustration with his battery drain: “Took the phone off the charger at 6AM. It’s 3PM now, and my battery is down to 41% and I’ve used it less than I usually do (only 1 hr., 15 minutes, no calls)…down to 36% since I originally wrote this message. That’s 5% in 15 minutes. Never did I have such drain before…”

One particular app that you may want to be aware of that teams up with the Android 4.4.3 KitKat battery drain would be the Amazon Kindle app. Yep, it’s draining significant battery life for individuals whose smartphones contain no root whatsoever. One user, Jeffrey, notes that “the first day after the update my battery drained in 3 hours and the phone was really hot!”

We here at Inferse want to warn you about what other Android users are experiencing with 4.4.3 KitKat. As it’s been said by a few reputable sources, Android 4.4.3 KitKat fixes some problems, only to bring new ones. Apparently, Sony’s claim that Google is to blame isn’t too far-fetched.

  1. It also changes the chrome UI in nexus4. The new chrome UI has issues. Sometimes I cant see the address bar when i scroll down. Also when navigating out of an app to home screen, we can see a glimpse of chrome, it appears and disappears. I am also facing some network connectivity problems, battery drain. ‘Android system’ and ‘Google services’ are critical drainers of the battery in my case.

  2. I have a suggestion based on on the unlock screen.I think that android sistem should be changed ! It must go a step ahead ! I would like to suggest that i hope the unlock screen should be different and be like apple’s unlock screen ! I really prefer it that way ! And in my s4 im using pin as my way to unlock and i cant use the camera shortcut if im using pin ! Android should change that and im really looking forward to it 😀

    • The beauty of android is the endless customization. There are tons of apps that allow you to have whatever type of lockscreen you want such as “widgetlocker”.

      Personally, I use the customization options of gravityBox. I can access the camera without even unlocking the phone. Furthermore only the pictures I take at that instant are available for review, not the entire gallery.

      I have an S4 as well but with Google Play Edition ROM installed.

  3. I have a moto g and after installing the update. My battery drained more than usually. Apparently there is an issue with the radio. So I had to root to flash the old radio to fix the problem.

  4. I got my update yesterday and since then I am having a nightmare charging the battery. It takes toooo long and doesn’t seem to cross 85 – 86%.

    The battery is also draining rapidly and phone is running hot. The native mail app is biggest hogger and is most of the times not displaying email body.

    What a mess and I will have to give up my Nexus 4 if a fix doesn’t come soon.

    Disaster! Shame on Google to have released such a shoddy update.

  5. I’ve had some serious Messaging app problems since my Razr updated to 4.4.3. I’ve had the notifications for MMS messages in the notifications bar, but when clicked on it brings you to the compose page. If I go to the message list, it won’t be there. Yet it will nag me with the 1 unread message on the app icon.
    I’ve also had problems in general getting the unread message sign on the icon to disappear, it usually requires a restart.
    Amazon Kindle has also been crashing in the background at least three times a day. I don’t use Kindle, so I generally don’t care, but the constant pop up is aggravating.

    • The RAZR just received 4.4.2 update. This article is about 4.4.3. It would be quite amazing if you received both in less than two weeks, but unlikely. I’m running 4.4.3 on an S4 with no issues. Smooth as butter

  6. Yep, my phone was much better at 4.4.2 now my battery is draining super fast and my phone restarted for the first time since I updated to 4.4.3. Need a new update fast or how can I go back to the previous firmware.

  7. This is un-acceptable, especially from a company as big as Google!I bought the Nexus 5 about 4 month’s after the initial release and I know I was blessed getting one that’s been issue-free!So when 4.4.3 came out i decided again to wait and read some feed-back and I’m so glad i did because there is absolutely NO FRIGGIN’ WAY I’m going to DL and install that bug infested version! like the ol’ saying goes…IF IT WORKS DON’T _UCK WITH IT,right? Googles devs need to get some ACT-RIGHT (super-strength) and get their SH_T together with the quickness and right all these wrong’s!! #EPICFAIL #UNACCEPTABLE #UGLY

  8. Funny, my phone seems the same..
    I have seen an intermittent issue where I have to input my pin
    to turn off my morning alarm … but that is about it..
    I have a Nexus 5 (Non-rooted) (With Telus, Canada)

    God I Love this Phone!!

    • Same issue with my Nexus 4

      “On nexus 4 camera app crashes like crazy. Major battery drain. Phone hearts up when using GPS. Worst update ever!”

  9. I think it’s stupid, do they not check what they release, I have a £500 day 1 release Galaxy Note 3 N9005 in the UK and still no update what is my phone already old? :/ do they only support their latest models….? Annoys me but I don’t care, I’ll guarantee I have it returned, I won’t lose out, Samsung will. Like everyone says Samsung is known for garbage aftercare. Money hungry as hell.

  10. Def battery drain on nexus5. And possible problem with video playback after 25mins of play time, stutters and becomes unplayable. Experienced in BBC iPlayer app which never happened before the update.

    Also gets hot.

  11. Sony Xperia ZL series phone users may experience such a severe battery drain (80% drain in 30 minutes)that it can result in the phone reaching temperatures over 55 degrees celcius. We have filed a complaint against Google Play with Health Canada because of the risk of users suffering first degree burns.

  12. After I did factory reset with no other app running, the battery is still drained even with power plugged in.

    It can charge fine as long as i leave it there with screen off and not using it, but battery is drained if I use my nexus 5 to browse the internet. never happened before with 4.4.2.

  13. My nexus 5 eats about 10% of its battery per hour while sitting idle. Android System is over 50% of that (currently 54%). I’ve even done a factory reset since upgrading from 4.4.2 to 4.4.3. The phone has only been in use for about two months now.

  14. Signal problems on my end with Nexus 5 on T-Mobile. Since the update when I change towers my phone forgets what data is until I reboot the device. Not even tricking it with airplane mode works.

  15. Why the hell note 3 haven’t get the 4.4.3 kit kat update?! I’m going crazy for the battery drain on my phone…. please i beg you… please release the update for note 3 SM-N9005… can’t stand this anymore…. T.T

    • Did you start getting the battery drain after the 4.4.2 update? I know this is basic advice, but try doing a factory reset. I had the same issue. My battery life was pretty much cut in half after I had updated. Did a factory reset and it’s back to normal.

  16. So when is 4.4.3 coming out for Sony xperia z? My battery is okay, not horrible. I just wanna know if 4.4.3 is coming out.

    • Alex, the 4.4.2 KitKat update just rolled out. What this means is that you’ll likely have to wait some weeks down the line (at least 6-8) before you can expect the new update. Android 4.4.3 KitKat hasn’t rolled out for any phones other than those from Google (Nexus) and Motorola. There is a Samsung Galaxy S5 Android 4.4.3 KitKat update in the works, but the 4.4.3 update has not rolled out for Sony, Samsung, or others at the moment.

      My best guess as to when you can expect the new update may likely be later this year — after Google releases a new update at Google I/O. Android 4.4.3 KitKat brings problems of its own, so Sony may wait until the new Android 4.5 Lollipop and upgrade its Xperia Z devices directly to 4.5 instead of 4.4.3. 4.4.3 is incremental, and I don’t see Sony upgrading to that when it could jump directly to 4.5.

  17. My t-mobile KitKat update for Note 3 murdered my battery. I went from ending the day with 30% left to having to constantly charge my Note. Worst update ever!!

  18. 4.4.3 update in my nexus 4 came in with a major set of issues with the dialer. The new look dialer app is frustratingly buggy and now I have moved to a third party dialer. The phone freezes every single time a call is made our received. The call does not move away from the screen unless I press the home key.

    Please report if there are fixes available.

  19. can anyone tell me how i can go back to jelly bean? i have the sony z1 and its running the 4.4.3 and now every time i get a call or a text msg it only plays through the earpiece . this did not happen when i was running the original jellybean version it cam with.

  20. Same problem as others battery drains much faster since updating to 4.4.3. Am using nexus 5. Tried to uninstall several apps but till now no success in slowing down the drain. Any suggestions?

  21. I have a Samsung Note 3 currently running Kitkat 4.4.2 without problems. I have rooted my phone (shortly after I bought it and have had no problems) and was wondering if anyone whose phone is also rooted has had any issues with updating to Kitkat 4.4.3. The disclaimer screen for the Firmware upgrade says: “Devices that have been rooted or modified with customised software may experience a failure during the upgrade process”. Your advice would be very much appreciated. Garry.

  22. HERE’S An IDEA GOOGLE:
    1. FIX the LOUD ear PIERCING BEEP’s that came with KitKat 4.4 or allow users like myself that HATE everything about KitKat to set our Androids back to the old system.
    (If not I personally will be suing for hearing damage and or starting a class action suit for those too that tire of their ears being physically harmed while using Bluetooth).

    2. How about fixing simple things such as not being able to hang up on one call without dropping the first caller.

    3. Allow MSN text messages to go through while on a call.

    4. STOP doing things to my $600.00 phone without my permission such as installing an update (KitKat 4.4) that I HATE and do NOT want)!

    5. Restore my voice text messaging. WHY would you take that away and replace it with nonsense such as emotes and pen writing! Asinine!

    In the being I LOVED you Google, anti spam advocators, reasonable fees, great customer service, Et tu Google, et tu? Now part of the wheel of greed, harassing adverts on my PERSONAL phone, forcing a customer to use unwanted and more importantly unneeded apps, features, etc.

    I know you can’t please everyone, but giving a CHOICE is a good way to start! Make the old version BEFORE KiTKaT an option!

  23. My Note 3 has been suffering from network connection problem after upgrading to Kitkat. I love my Note 3 when I first bought it and sucks now. My signal has been up and down for about 5 minutes. I’ve been searching somehow to address this issue on my phone and I couldn’t get any answer from google. Please, please, have this fixed. Hope to get a new update. :'(

  24. My note 3 connects to wifi but does not get internet .ive tried everythimg and nothimg seems to work. This update screwed me. Hopefully something is done soon

  25. I Don’t experience the battery drain issue much but my tablet Z got worse after the update. it lags pretty much every time i’m using it and its really a nuisance. i tried to run a bench mark test and my score dropped from 23000 to just 14000… i don’t know what happened but i’m looking forward to Sony that they will fix the problem sooner

  26. my nexus 4 is getting over heated and it takes around 7 to 8 hours to charge. Battery drains really fast. GOOGLE this is a huge disappointment. Kindly fix the issue fast or will move back to windows phone.

  27. First week after upgrading to 4.4.3 was bad with high battery drain and deep sleep in the 13-30% range. Now it’s back to 70+% and battery life has never been so good. I think it’s at the 4.1 level or better since I have some battery hogging apps like K-9, syncing 5 accounts, and about 10 IMs. I’m losing about 2.5% an hour. Also have 5 emails syncing on email, K-9, cloudmagic. My nexus 4 is smooth and responsive like a new phone. Google has done a fantastic job for 4.4.3, can’t wait for 4.4.4. It doesn’t run hot either but that could be due to 3g signal strength, need tip monitor that for a while.

  28. The update is turning a previously super reliable and fast Note 2 into a paperweight. Where it always connected to wireless quickly, it now takes 5 minutes or more — sometimes I have to restart the devise. It also drops off frequently. The freaking phone icon vanishes occasionally! WTH?

  29. After Kitkat update in my Note 2, I am facing hell lots of problem like automatic restart, No display while unlocking, Hanging issues and Battery draining fast if Bluetooth and WiFi is On. Any solution to this??? Can we roll back to previous version???

  30. So, I JUST got 4.4 last night, it sux. I came from way back (4.1.2) to 4.4 and let me say it is the worst! First off the few things I noticed. It killed my 4g LTE data. in fact, i got no data, at all. Bluetooth signal was….well lets just say more than 3 inches from the phone was too farI didn’t notice the battery drain or reboots, but I didn’t delve too far into it. I notices no data and said the heck with it. I was able to reflash it back to I317UCALJ2_I317ATTALJ2_ATT stock rom (unrooted and with odin) and didn’t have an issue with bricking. I don’t recommend it! You know, Just in case. I did however have to do a factory data wipe using the system menus, so…if you try and it’s not getting past the samsung logo power button, home button, Vol. Up factory data wipe, then reboot, then it should load proper. If not don’t hang me, I’m not a tech. (ATT Note 2 SGH-i317)

  31. i have just updated my galaxy s4, from 4.1.2 to 4.4.2, i notice my battery drain off rapidly, when i unplugged it from charging where the battery level indicated full 100%, less than 20 minutes the battery level drop to 90%.

  32. I just updated my S3 and the battery drains abnormally fast, the 4G mega drains my battery now, couldn’t imagine how fast LTE would drain if I ever used it.

  33. All we want is the home button led to work so we can SEE that we missed a call or text while at work. Please fix that issue. 🙁

  34. Google has to change the denied access to read/write to external micro sd card in kitkat 4.4!!! This is a very very bad issue and annoing!! Bad Google BAD!! 🙁

  35. ok, att service, note 3 phone, 2011 bmw x5
    after upgrade to 4.4.2, bluetooth stopped working in any useful way.
    Called BMW, not their problem
    Called ATT, not their device
    Samsung tried with all the soft reset and safe mode crap. nothing worked. they recomended hard factory reset. not good, too much data and from the forums, would not help anyway.
    I found a simple yet less than ideal solution. pair your phone to the car but do not allow the car to download the phone book or messages. I know it is less than perfect, but I can now take calls without losing BT, have to make calls from the phone though and use the BT audio like before.
    Good luck
