[Lenovo K900] Sw33t_Lov3r:
Hello,

I think I can't help you with the call drops. :/ But, which ROM do you have? Maybe you need to update.

Anyway, use AirDroid app to avoid using the usb cable. It's still fast and easy to

upload and transfer files. Or you can try ES File Explorer's FTP Remote Manager

to download your media to your PC. I think it can upload files to the smartphone too, it has several features to manage

files through network, including cloud storage managing from the app itself. It's really good and for free. You may already know it.

Also you can try Team Viewer (for Android and Windows) to browse files in your

computer's hard disk drive and transfer them to your smartphone (and vice versa). Team Viewer is very useful for that

(and other things), cause you don't need to be in front of your computer to browse and transfer files to and from it.

Although, reviews say Splashtop app/service is faster to stream the PC screen

(specially for videos and games). :/ Team Viewer does struggle a bit if you want to watch a video remotely in

your smartphone's screen. It must not be meant for that, but for

transferring files

is great!

Btw, to stream through UpNP/DNLA use BubbleUPnP UPnP/DLNA app,

it's simply wonderful and has many useful of features, that way you can easily watch, listen and view all the media you

have in your PC on your smartphone's screen (and send them to your TVs and other smartphones that can be connected

to speakers, etc. Many uses); no more copying, transferring videos to watch them in the mobile (even better for you as there's no SD in the K900), at home at least.

Actually, no, it's capable of internet streaming too, check it out:

For the memory:

Seems like your K900 is not rooted already, but if it is get ROM Toolbox Pro.

It's the best app I tried to deeply tweak the device. And if not, do root it (some way?)!

With ROM Toolbox Pro I managed to tweak so finely my Xperia Pro that it currently is running very very smoothly and fast

with all kind of apps I use; from games to everything! The same ones that in my Razr i (stock ICS). At first after a reboot it was

at 120MB free out of 335 RAM and there was several processes and apps running, now every reboot it's at 210 to 217 MB free

with only 85 to 90 MB used. And it has running the Play Store, Ocean HD live wp, Settings, email, Swype+Dragon keyboard,

Google Services, etc on the foreground, with all that it still manages to stay with 185 to free 200MB while using the device. For

a system with a total of 512MB (335MB usable?) is the best it can get; Gameloft games (like Nova 3) run with no problems and

with high graphics (enabled through Chainfire 3D), everything is so sweet with this device ^-^ ... Oh, I'm sorry I went a bit too far.

So, yeah, ROM Toolbox Pro is great to put your device to work as YOU WANT it to work, and unleash their great potential like I did with my Xperia Pro.

62% used

is not that bad. With some 700 or 800MB free this device must be running perfectly smooth and multitasking

must not be affected at all. Am I right?

I think your consern must be/should be about battery life not exactly RAM, as I've seen since I managed

to tweak my Xperia Pro, its battery life increased noticeably (at least 30%) Cause the more processes the more battery drains.

Anyway, the Lenovo Launcher sounds quite heavy, but it's worthy, right? Or, if you don't like it there are several others, but I'm

affraid they will use almost as much RAM, maybe. You can try.

The Settings app has an encryption feature for the content in the SD (K900 is emulated SD), if you don't use it you can

disable its receivers and services

with the Advanced Freezer of ROM Toolbox

(App Manager -> long press on a process -> Advanced Freeze), it's easy. I did that with the Settings app in my Razr i, and from 65-75MB RAM used it went down

to 40-45MB n.n Now the Settings app reports: "1 Process and 0 services" I try to do the same with all of my apps,

ha. Most of them have services we users don't need, specially the system apps.

The stock keyboard can be changed in settings, just install another one and it should be better and with less

RAM usage. I use Swype kb by Nuance, it has been a pleasure to type with it. It's costs just one dollar in the Play Store.

And, just to add this also: There is a very useful, light and free app called Screen Filter by Haxor Industry,

it's an screen dimmer. It's much easier than tweaking values for the brightness of the screen and very useful at night.

I have the screen (AMOLED) of my Razr i configured to almost 0 brightness and it is still bright (nice looking, but bad for battery)

so I use this app to reduce to 50% the brightness. It's simple and easy, but don't remember if it has ads cause I have the Ad Blocker

from Rom Toolbox on ^-^ (so sweet app). Btw, my version of Rom Toolbox is one outdated (5.5.1), I don't update cause in the newer version

the Ad Blocker was removed because of Google's request. Also the latest version has a different UI (Halo?) and I don't like it.

So, these are my advises: Get rooted, get Rom Toolbox Pro and tweak away!

There's no need for a custom rom! You can "build your own" haha :D

Tell me if it was helpful and if you need help in some other things related to this. I hope this helps everyone some way ^-^ And that silly Lenovo releases

this soon in my country (Peru) or else I'll have to pick the Galaxy S4 for an on-contract upgrade in September u.u

- L.

Pd: Do get the other apps I recommend to you! Are a must have!

My screenshots so you can see what I was talking about. And there are many things to do to the system to improve it's performance (even further) and battery life,

but they all are related to deleting/disabling unwanted apps, background apps/processes, and managing receivers so no app starts with the system startup

unless you want it. So root is needed.
