Hi guys ive got a Samsung s3 which is on 4.3 official stock rom, however im having some problems. Firstly is the problem of lagging, for example i could be using the browser and when i go back to the home screen there is nothing there and it takes a few seconds for all the icons to load back.

Second problem which is intermittent and usually goes away when i reboot the phone is when swiping through the homescreen i get these weird screen flickers (Not sure if screen flicker is the right word) but basically i can see my other app icons in the background which become enlarged. I have included some picures to better explain. Do you think this is a hardware or software fault and what should i do?

Any helps appreciated, Thanks.

(1) Backup any files photos then factory reset

If problem still there

(2) Flash another stock rom with Odin

If problem still there probably hardware related :)

I have the same problem. The flicker of the screen I think is touchwizz because when I use another launcher dissappears.
Normally with a reboot I fix it, but it happens again from time to time.

Sent from my GT-I9300 using xda app-developers app

I also got that flickering on TW launchers (even on an S5 themed one). And actually, it's not a flickering, it is a stretched app icon (in the screenshot you atached it is Camera). I observed (at least in my case) that this happens when the RAM usage is above 700-750MB. try a custom ROM (after backing up, recommended) like SmartDroid Simple v7, NxTGen 13.1, ehich both have really good RAM usage (on Smartdroid v7 I got as low as 280, if i remember well. I posted the screenshot in that thread.

I had similar problems after updating from official 4.1.2 to official 4.3 (MJ9 ROM, November 2013). Problems were extremely widespread. I got sick of waiting for Samsung to even acknowledge the problem and eventually moved to NeatROM, and I'm happy to say I haven't looked back. I will probably never return to stock now.

How to clear ram? Thanks. :)

update for this thread :)

You bumped within a couple of hours? Why?

- Go to Settings > More > Application Manager > Running > Select the app you want end and click "Force Stop" (Please make sure you dont close any important app)
- Hold menu button until you get the recents bar then clear all
- Try "Greenify" and use that to reduce the number of running apps.
- Install a custom-ROM like SmartDroid, it is lightweight sammy ROM and uses less storage and RAM.
