[Krishnanmshr]

My phone previously just lagged but now am getting a new problem it's auto shut downing while using apps like WhatsApp.I don't have any anti virus installed n I have latest update and I have free ram n internal storage of about 5 gb although my SD card is almost full plus am disappointed with the quality of photos that my cam takes

Free RAM will fluctuate as you open/close apps, you should reinstall the latest update with PCC, also do you have any antivrus or taskillers?

Hi Krishnanmshr,

Welcome to the community.

Ram is definitely a factor with performance on a device, however so is storage space and CPU power. Although you may have 500mb of ram left, you may be lacking in storage space, you may also have an application on your device that is not optimised appropriatel and is causing issues with performance.

The best thing you can do is go through your apps and try removing some to see if the lagging goes away.

On other thing to note, this issue could also be due to a SD card playing up as well as a SIM card. It may be well worth, backing up your SD card and trying to format it to see if this helps.

Let us know how you get on.

I have about 5 gb of space left in internal storage and microsd card almost filled and have some basic apps like whatsapp temple run clean master zoombie highway mx player etcI have no anti virus installed but have scanned my device via pc '9quick heal mobile scan) and no threats were found. It just lags once when i unlockmy screen and go to the menu that time it just lags for a minute

Have latest updates installed in my device no updates now

This could be a result of a full SD card, I suggest trying to remove the card and test for a period of time and see if the issue continues, remember the device is also accessing the SD card, and needs to find specific data on it, if it is full that timeframe becomes longer.
