Ok, after 48 hours with KitKat, I've had enough and flashed back to S124.

Lot's of things I like with 4.4.2 but the few bugs I can't live with!

- Camera quality is nowhere near as good, images are more blurry and the shutter speed is shockingly slow (due to auto focus)

- The UI looks great but it just doesn't handle as smooth and quick (frequently doesn't pick up touches). Often have to jab at the screen twice and it's just generally unresponsive.

- Proximity sensor when making calls doesn't work, if I look at the phone, the screen remains off. Have to press lock button to see the screen.

- Several apps don't work properly like UC Browser mini and Light flow. Often crash during use, even with a clean boot.

- New power manager sucks, it's too simple and not enough control.

- Keyboard is Android AOSP and has no swype and the predicition is not as good (latest Google keyboard is not as good either - S123 much better and more accurate).

- Less RAM on a clean reboot and the cleaner doesn't show real time RAM free.

- Little bugs like not being able to select a custom ring tone (comes up with error "android.process.media has stopped").

Am back to S124 and a happy bunny, might revisit KitKat with the next release if there is one.

[Lenovo P780] haree:
Stock 4.4.2.

but the launcher is like apple im not comfy with it
[Lenovo P780] Supermatt01:
Well ART is a bit smoother and faster Dalvic is more stable and compatibility is better on it with a greater number of apps.

It's stockish it has the same user interface as vibe ui.

Wondering you OTA from S124 to S214 or S220 rom ?

S220 has bad camera, it does not focus well for me. Just need to find out how I can get it right. At the moment back to S124.
[Lenovo P780] drsparsh:
I am on s220
[Lenovo P780] Supermatt01:
I'm also on s220 but even though the camera won't work I like it. I'm just going to wait for the fix.

I have been using Kitkat P780_ROW_8G_S221_140729 for a while now.

The battery backup ever since the Kitkat update has been reduced drastically. My phone which would give me over 2 days easily now gives up in under 1.5 day when using wifi and 3g on 1 SIM for the entire day minus 2am-5am when the phone is in 'Extreme Power Save' mode with everything apart from cellular network switched off.

After 1 day 7 hours, 24 minutes, my battery is down to 29% with:

InCallUI has used 41.5% of my battery as of now (I had more calls yesterday, usually it is 25%),

Google Play services has used 28.4% (it is usually 38%+)

I have never seen Usable RAM even touch 200MB with stock launcher. Irritated with this, I switched the launcher to Google Now launcher and now the highest I have seen is around 260MB though on an average, it stays between 225MB and 235MB. The general UI is now laggy even though the AnTuTu score has improved from 12xxx to 16310.

The camera now takes ages to power up and the general experience is ****ty since I have to click each picture at least 4 times and hope I get a focussed shot.

I am extremely dissatisfied with the kind of experience Lenovo has provided on the P780 since the kitkat update. If there is any method to fix it and still keep Kitkat and the warranty, I would be extremely delighted to implement it. If there is no way, it leaves me no choice but to downgrade to the much more functional Jellybean ROM.

As it stands now, my wife's Xiaomi MI3 (which is also on Kitkat 4.4.2) with its 3050 mAH Battery and the Snapdragon 800 chipset is easily outdoes my phone in battery backup. Please help me fix this on priority,
[Lenovo P780] anilyarki:
Few things that i suggest you do before planning to downgrade. Jelly Bean is good but cant match the stability and performance of Kit Kat version. I have been using the S221_ROW for about a week now and prior to that as well. Here is what i suggest you do in same sequence as mentioned below -

Calibrate your battery - Use inbuilt power manager or Battery calibration by Nema from play store

Change the run time from Dalvik to ART from developer options

Use developer options to keep the windows animation speed to No animation

Use Nova or Apex launcher as your default launcher, make sure after installation you go to system settings then Home and then choose Apex or Nova as default. Other wise even though you will be using Apex or Nova the stock launcher will keep running in back ground, which in turn will slow down your phone.

Only use Lenovo provided charger to charge the battery. Ensure you have a check on Sine wave power saving technology. This greatly helps in battery endurance.

Finally if you are Rooted then use root uninstaller to freeze Google apps that you do not intend to use. Google services in the background takes up a lot of resources and eats up battery randomly.

I hope this helps. Trust me Kit Kat is way better then Jelly Bean when it comes to memory optimization and power management. I am connected to Wifi 27*7 and use my phone for watching videos, laying games etc,.. i am a very heavy extreme user but still my phone manages to get me through 2 days if not then close enough.....and yes i am Rooted Cheers !!

Can you please tell ua the steps you used to fully root s221 even after reboots? thx

How to Root S221_ROW firmware

Make sure you have all these things --

Stock S119_ROW official update for scatter log flle. Check other threads here to get the download link if you dont already have it. ONce downloaded extract all the contents to a folder.

SP Flash Tool V3.1304.0.sn119 - Search google for download links

TWRP 2.6.3.0.img or New

superuser.zip - get the download link from OP

How you do it -

Switch off the phone and use the reset button to power cycle it

Launch SP Flash tool and click scatter scatter loading, Browse to target_bin folder inside the Stock S119_ROW official folder. and select MT6589_Android_scatter_emmc

Once all the files are listed in SP flash tool, Uncheck everything except Recovery

Now click Recovery to manually select the recovery image. Browse and select TWRP_2.6.3.0.img file

Put a check on DA Dl All with checksum in SP flash tools.

Click Download. Do not click firmware upgrade

Wait until you see a green circle. Once you see it. Disconnect the phone from PC and reboot into recovery. You can hold power plus volume up and down buttons together to enter recovery. Once in recovery flash superuser.zip file. and reboot.

You are rooted with superuser. If you want to switch to superSU instead, you can simply download it from playstore and install.

Notes : Please ensure you install Lenovo USB drivers to the PC prior to installation. Also keep the device manager open if you are connecting the phone to PC for first time. As soon as you connect the phone device manager will show a unknown MTK device. Windows will fail to install the drivers for this. We need to manually install the drivers. Drivers for this device can be located inside of your SP flash tool folder.

And finally I or anybody at XDA are not responsible for any damage that might be caused to your device. Hope i helped you. ;)

Try to use Geno to root your OS.
[Lenovo P780] jd.21:
how did you get 500mb free memory in s222 update. i didn't see any difference after updating to the latest version s222 as it's same as before like 210-280mb free ram even after restart. sometimes rarely moves above 300mb.

is there any tweaks to get that free memory?. or am i missing something.
[Lenovo P780] ~semsem~:
+1 i never get 500mb free memory on s222
[Lenovo P780] anilyarki:
Yes i did have up to 500MB free RAM available but that was only possible intial settings after fresh ROM installation and there after rooting the phone, removing all un required applications and setting up the runtime to ART from dev options. I am also using universal Init.d support app with Kill Joy script

Before anybody proceeds with such things i would how ever like to mention that i am only using whatsapp and facebook along with some games on this phone. Install boot manager to see all the apps that start automatically, then remove any which you do not need. Basic operating system requires just about 220MB of RAM to wrk properly. Anything installed over it may take away available RAM.

Note : I am not responsible for any crashes and FC's. Just sharing my experience and possibilities with Android Kitkat. :victory:
[Lenovo P780] jd.21:
so the free ram memory is not from stock S222 update, after root and tweaks only we can achieve it, correct?. yesterday only i flashed kitkat one by one update. even without installing any user apps the free ram between 220 to 280mb only.

kill joy script, i already tried that in my previous fone p770. but i didn't feel much difference in performance and battery. i don't know how's the performance in p780 with kitkat. could u plz, reply about ur experience with "kill joy" in KK. in kitkat battery backup was reduced drastically i can see the huge difference. ex. in JB while using wifi with dual sim standby the battery consumption in one hour was 5-6% only. but, in KK the consumption is 9+% in one hour.

we can use in-built security app for apps that boots at startup. there's a option to enable and disable. but, only user apps can be modified.
[Lenovo P780] jd.21:
[MENTION=5402718]anilyarki[/MENTION], could u plz, reply about your experience with KILL JOY in KitKat.
[Lenovo P780] drsparsh:
can u tell me where I can find geno. what I got from Google is not working for me. and I dont want to change the stock recovery.

Here it is.

Made 28.08.2014.
[Lenovo P780] anilyarki:
HI,

Unless you are very confortable with mods and scripts i suggest not to install this script. Although it does free up a lot of memory and also makes phone pretty quick, i did get random FC's here and there. camera crashes randomly while switching over to HDR mode, some times call screen would not give you an option to end the call etc etc.

Not that it happens everytime but like i said random FC's. If you are ready to reflash everything should something seriously fails inside the phone then give it a shot. As long as everything works it works like a charm !! :good:
[Lenovo P780] jd.21:
thanks for the reply. previously i had experience with these scripts. just i want to know whether it's worth a lot to install these scripts or not in KK that's all.

---------- Post added at 12:41 PM ---------- Previous post was at 12:38 PM ----------

this software is in full chinese i think. is there any guide or instructions to do root with this tool.

did u root your fone with this tool only?. if yes, then give a full guide here on how to root s222.
[Lenovo P780] jd.21:
new firmware update s223 is available. just now updated. but, forget to copy the update.zip file.

anyone can upload the 210mb size file here or in any filehosting site or google drive etc., to download to keep a backup. i have all the other backups. this time missed it.

to find the latest update file, after download complete don't update immediately, click any other option other than "update now". then goto filemanager=>internal memory/sd card memory=>googleota folder=>here u find the newly downloaded update.zip(210mb) file. and copy(don't cut & paste) that file to anyother location and upload it to any filehosting site to download then provide the link here.

note : after updating firmware the update.zip file will be deleted from the storage automatically.
[Lenovo P780] cybertech:
Will the root be gone after updated to S223? Saw the update but did not proceed.
[Lenovo P780] jd.21:
sorry, i didn't root mine before this update. so i don't know root is available after update.

could u plz, download and upload the new update for me?.

thanks I have rooted s221, but now iam unable to update. So I want to unroot it and I want stock recovery to replaced... Can anyone please help..
[Lenovo P780] s_john8686:
Ok, I just found it. Enjoy :)

http://www.4shared.com/zip/ev5pPzApce/S220recovery_img.html

Finally, I managed to upgrade OTA with rooted S222.

******************************

Instructions (for those already rooted their S222) :

1. Download the above zip file

2. unzip you will get a "recovery.img" file, place it in your SD card, not in any folder

3. Flash the stock recovery.img using mobileuncle tools, after flash you need to restart your phone

4. Once you restart back into system, you will have a rooted phone with stock recovery

5. Goto system update, let OTA takes care of everything, then you will get updated to S223

*********

6. After you updated, you will be having S223 "unroot" rom.

7. Root in again with the flashtool => TWRP 2.7.1, then flash superuser.zip file as usual.

8. After you have got it rooted again, you may want to again flash the recovery back to stock recovery, so you will get future update :D
[Lenovo P780] ashketchum:
No need to unroot or flash stock recovery. Update can be installed using TWRP as long as you haven't removed or replaced certain system files. After installing update, just install superuser.zip again.
[Lenovo P780] JackSparrow17:

Stock recovery has come but when I click update now it restarts and shows a android icon with error on it...I tried 3times...
[Lenovo P780] s_john8686:
Once you flash back to stock recovery, there is no need to upgrade thru the stock recovery. Just do OTA update in system will do.

Or create a googleota folder, put the update.zip file in it, go to system update to click it then it should run. However, if there is anything (in system files or what not) you have modified/deleted, then the update might not work.

For me it was quick and easy.

anyone here can help me?. i forgot to take a backup of latest update s223. please, someone upload the new update.zip file to download. any help will be appreciated. :good::good::good:

system/etc/firmware/modem_1_3g_n.img has unexpected contents.

error executing updater binary in zip '/external_sd/update.zip'

what is that mean?

and how to update it to s223.

i already try to back to stock recovery and flash back to modem s104v_S222 but still not worked
[Lenovo P780] ganapathyraman_s:
I faced the same problem because I had replaced the stock modem with another modem.

Reverted back to the Stock modem and then tried update and it worked.

Replace the modem with the attached img file, set the permissions, reboot to stock recovery and try OTA update.
[Lenovo P780] ganapathyraman_s:
Before deleting, if you had backed up the deleted system files using titanium backup, it can be restored. If you used root explorer and deleted it, the file is lost. Correct and foolproof method is to flash the ROM it again using SP Tools.

Than SPTool from here http://xdaforums.com/attachment.php?attachmentid=2886400&d=1407330071

Than Drivers from here https://www.androidfilehost.com/?fid=23252070760972673 and instal the drivers first....

Assuming the drivers are correctly installed, run the Smart Phone Flash Tool.

Click on scatter-loading and choose the scatter file "MT6589_Android_scatter_emmc.txt" of the ROM you want to flash.

Make sure the checkbox "DL DA All With Check Sum" is CHECKED

Click on "Firmware->Upgrade" button.

Plug in your powered down phone via the USB cable again. See it flash.

When a big green circle appears on the screen, your are done!

I unzipped the drivers file but there isn't a setup file there... . please tell how to install the drivers.
[Lenovo P780] stympy:
Hi. Look what you have to do: please read this till you understand.

1. Power off your phone. Skip that if the pfone is powered of.

2. Open the device manager window;

3. Plug the phone to your computer;

4. At this time in Device Manager appeared for a second or two not in USB area something with new preloader port... or something; i cant remember..

5. Click very fast on it because that will desapear very fast.

6. After you clicked on it all you have to do is update driver from archive you downloaded without exe files, and voila you have drivers installed and now all you have to do is to flash you ROM.

7. To flash here is what you have to do: Unplug the USB cable from your phone;

8. Open flash tool

9. Load scater file

10. Check DA/DL WITH CHECK SUM

11. Select Firmware upgrade and start;

12. Now only now plug your cable in the phone

13. Flashing should start now.

14 Wait til flashing finishes and start your phone.

Hope this will help you.

Good luck.
