[Q] Exteme lg flex 2 lag

I have had My sprint lg g flex 2 , for 3 days now....and I've been using it non stop. I was expecting a smooth beautiful phone...with the Qualcomm 810 but I can't even listen to Spotify and surf chrome without extreme lag, or an app closing out. The lag will come and go....and its actully lagging as i write this....i have nothing open.....I think its mostly a ram problem...and I'm so confused because they say the g flex 32 GB variants have 3 gbs of ram....mine is 32gbs....but I have 2....anyway...I've attached a video for proof of the lag...I've updated everything and everysthinga stock with about 20 apps installed....this is very frustrating because I didn't even have this much lag coming from my g2 and that's 2 years older..so I would love it if someone could get me some sort of help!

Chrome was my problem.
Left it and the overall experience is better.
Not perfect though.

Lol definitely not chrome, it's my phone.... It could be a combination of Spotify, and Skype, and Spotify would is shut off it's mostly a ram problem

It's probably memory leaks. I changed my thermal throttling and I still have that happening. It's a known issue in 5.0. We will probably have to wait until we get 5.1 to see real relief. Often I am forced to restart my phone because it wont respond because it seemingly can't load anything else into RAM.

I'm pretty sure this is a ram issue. I've never experienced that with my 3gb model. Although the lag you're experiencing is what I had with my S4 with android 5.0 and it all got fixed when I upgraded to 5.1.

Ahhhhhh okayyy ...that helps I looked it up.....and I see that memory leaks are a common glitch in 5.0x other than waiting for sprint to push out 5.1x , is there any fix?

Unfortunately it looks like the best method requires Xposed which we can't install right now. You could try an app that will kill apps that are using a lot of memory. I don't have any recommendations though since I'm not currently using one but may end up trying it out soon since I'm getting tired of restarting my phone.

Hardly, it makes it useable though... Also the thing about xsposed, how come we can't use it, I know there is a beta for a lollipop? PS..... regardless I can't root because I'm on a lease with Sprint, can't risk, loosing the warranty ?

Currently there isn't a way to install the framework without an unlocked bootloader. It's possible that could change at some point but for now it's not possible.

I was fine on my g2 installing xsposed on 5.0, but I did have an unlocked bootloader, I know there's a root method for the Flex 2, but I guess there's no boot unlock?

On my S4 with 5.0 it helped to run the app Greenify with root access. I would have it hibernate apps I didn't want to have taking resources in the background. Made a big difference for me. Even without the xposed features it helped a lot.

I heard about greenify, I downloaded it about 3 hours ago, I'm not using it with root access but my phone hasn't been slow since

really XZ became so laggy

Hi,
I have the dual sim version... since a quite long time I am suffering from unbearable lags... I am not sure, which update caused that and for now I am on the latest "41.2.A.7.35".. my symptoms are as follows:
- high RAM usage.
- phone becomes laggy so I know who is calling in couple of seconds after ringing
- switching between apps became impossible (like between GPS and phone call)
- sometimes I open it and I see the applications icons on the screen are refreshing like if I have just restarted the phone.
- i do 4 to 5 restarts per day to make the phone functioning but this is very annoying.
I found another thread in sonytalks about the same... they recommend to turn off google feed which is what I did 5 minutes ago and still don't know the result.
https://talk.sonymobile.com/t5/Xperia-XZ/Very-Slow-processing-what-happen/td-p/1240359/page/4
Do you have an idea, or fix, or shall I simply change the phone?
Thanks,

Same here.
Just sit down and wait for Sony release a new FW.

well i finnaly managed to get my xz working how it meant to... by unlocking bootloader....rooted.... and then flash latest ftf and andro kernel v28 and then i flashed rytekk`s battery perfomance tweak https://forum.xda-developers.com/xperia-xz/development/tweak-small-tweak-battery-memory-t3637240 and im happy that my xz really works now...definetly faster,smoother all around then stock non rooted.for me this is only solution...but im asking myself how they cant make a smooth stock non laggy device especialy in year 2017 where chips are so powerfull...and yea someone will say get an iphone but for me an iphone is like having an android phone with kernel enabled constantly to max perfomance with no downscaling LOL no wonder iphones drain so quickly...i just hope that brands will focus on software optimisations in the future and not so mutch about specs but yes at the end this is there strategy how to sell products.

Sad to hear it. I changed from Honor 6X.
Honor is good with their EMUI, and it also has the best fingerprint sensor that I ever used.
But I need a water proof device, so I picked XZ.
Not sure it is a good idea

Good to hear that. So we can fix or wait for SONY fix it. I have no plan to root or flash any custom FW

i think they dont want to push chips at max just to be on safe side...thats why maybe sony baterries and as a whole device can last mutch longer then Samsung devices...and did u ever heard about exploding Sony device?i still didnt...but if i pay 700e for a device witch is flagship i expect to act like one...why put a sd820 in a device when u dont even use full potencial...lamers...

BTW, removed Messenger Lite and FB Lite, RAM dropped from 2.5GB to 1.8 GB.

Im alergic to lag and what ur experiencig made me so mad that i had to unlock booloader and find solution to it...but as i told before this is not official solution...Sony really needs to consider about that....why we have to root the device to make it usable for our terms....Im looking in to Nokias these days and hope they gonna gonna be good...and my last Sony phone is definetly XZ .Im not looking froward to it anymore.

Try disabling the app Movie Creator and see if that helps. That was the cause in my XZ.

same like me... this is my last sony phone ever.... the phone should serve me... not me to serve the phone by disabling half of my apps aiming for a stable performance... this should not be the case

In my case, it seems it was the the latest update of Movie Creator doing something and not related to the firmware itself.

Having the same issue with my XZ Dual. Laggs are driving me nuts all the time, rebooting doesn't help for long. I have also noticed that my phone usually have loadavg at least as high as 18 all the time (do cat /proc/loadavg in terminal). Pretty overloaded.
The quickest possible way to find our who is slowing device should be running ps or top in termnal. But unfortunatelly they have very limited output without root access. And getting root is such a pain for this device.

I've noticed that my XZ started to lag after the July security updates. Maybe it has something to do with that?

Mine was lagging since at least June. Did a full wipe (i'm on stock), lags returns after reinstalling apps.

had the same issue , disable the movie making app that came with the phone ,

well rooting this device its not even close to pain ...i unlocked also Z5 before without a single problem and also backed up DRM keys and restored also without problem..the same way is for our XZ everything is clear and tested before...i never unlock booloader if there is not no option to lock it back...i check first...but i dont advise u to do that if u dont have experience with adb and flashtool...wish i would not do all of that stuff for my xz but i had to cuz its the only way to get it working smoothly.

My XPERIA XZ is draining too much RAM

Howdy! Is anybody experiencing the same problem? I just bought my XZ and I've been using it for like 3 days. I didnt install any heavy games or apps, just some basic ones. But my phone is using too much memory, I only got about 200-300mb left, compared to ~700mb free on the first day. Though I'm not experiencing considerable lagging. It's just that I find it weird since I found other people having up to 1GB free.
Is this common issue or just mine? Please help me. Thank you all!
Btw, does AVG Protection prove useful in terms of ram boosting or so? Or should I just disable it?
Mine is on Oreo 8.0.0, build number: 41.3.A.2.99

S8+ Low ram + bad performance issue need help

So ive been having this issue lately (on latest updates), running G955F (s8+) stock unrooted and knox still intact. I have like really low ram between 300-400mb and device lags all over the place . For example i cant leave games open that will close automatically after a while or if i need to see a whatsapp message most other backround tasks will close too which is anoying . And yeah i know how android works and the fact that more free memory doesnt mean better performance exactly, but when theres too low memory then apps starts to be killed etc , which gives bad performance overall.
To clarify all of this , i hard reseted the device already and when it boots with just whatsapp and messenger (not even facebook installed) i have already this low ram, been disabling apps with package disabler and free ram doesnt change. Tried also on developer options to limit proccessess with no avail too. So whats happening ? whats eating so much ram and why it doesnt free up ?, on later patches i used to have my common and pretty standart 1.5 to 2.0 gb free ram , now i have device that feels like galaxy s3.
Could it be faulty hardware ? i just dont know anymore at this point, i really tried all i couldve think of.
pd: I have latest stock DBT up to date with latest security patch too.

Same problem facing by me.

I have told many ram management since 6.0 and up is awesome Thats what it is supposed to do...
To the OP I would find the apps using the most and see if you can get rid of them

Hard Reset

I bet that your phone is full of many apps, go for hard reset.

If I restart the phone, it continues to work fine and free ram is actually good , but as soon as I continue to use the phone then it starts to be less and less free ram available till 300-400mb when phone starts to lag and underperform.
And yeah I try to clean ram using in built device maintenance but when it gets too low it just doesn't change no matter how many times I free it,always stays at 400 or something and phone lags.

I got 1.5gb-1.3gb always free. Do you have stock samsung rom for 955F?

Yep ,stock Samsung unrooted same model as you. With messenger , WhatsApp and Pokemon go as only apps installed.

i also have a lot of apps and have 1.1-1.3gb always free. In settings>apps try to click on each app and u have an option to run in the background. try to disable that and see if ur ram usage drops.
---------- Post added at 09:56 PM ---------- Previous post was at 09:51 PM ----------
And also try to disable things.... try to buy a package disabler from google play and disable stuff u don.t use..

I think its a hardware problem, but as a last resort go for resoft other rom or same rom.
Do this ONLY IF YOU DONT HAVE WARRANTY, if you have, send it.

My exynos s8+ is lagging until i could not even toss the pokeball properly. I have to struggle real hard to play pokemon go. I really could not believe what I am seeing for a 1 year old phone. This is very likely to be my last android phone.

Your ram is probably faulty, get it repaired.
Btw mine is from 20th of April 2017 and still flies. No reboots or anything between charges. No lag.

low free RAM

Recently I've noticed, that by p20 has never got more than 1.9GB of free RAM. I never leave any apps open and usually close them as soon as I stop using them. Anyone else encounter this?
I'm on official emui9

Android has a different Ram-Managment than PCs. Free Ram is wasted Ram.

Thanks for the explanation, I'm a bit familiar with that, but I was just wondering because none of my other Huawei/Honor phones use this much RAM when not really doing something in the foreground

Good question, I don't really know. The only Huawei/Honor device I've got right now is the Honor 8x. I know that it's got the AI camera and everything but not if there's more. RAM with that phone is always between 2 GB and 2.4GB free with my usual usage (and emui9)

I'm not bothered by having less free RAM as the experience is still very fluid, snappy and fast.
I'm just wondering
