ZTE v965 - unstable device - Android Q&A, Help & Troubleshooting

Hello everyone.
I'm here because I have a problem and I need some help.
As stated in topic - my problem is about ZTE v965 phone. At the beginning everything was great, I didn't even expect such good phone for such low price. But my device became unstable, especially when I try to start a 3D game or even benchmark (sometimes 3D test from AnTuTu does not even start). I've been trying many ROMs for my device and that's probably the cause, I've flashed many of them, got one brick and many bootloops.
And right now, no matter the ROM, my device is suffering from a very small amount of free memory. v965 has only 512MB RAM but most of the time only about 50-100 is available and it used to be about 250MB after cleaning. I'm experiencing many FCs which are most probably caused by OOM. For example, I had no problems playing RR3, Eternity Warriors 3, Death Dome and others - now most of the time they just FC after the beggining loading. I even have problems with PowerAMP playing in the background of a web browser - one of them usually stops. Under the "running processes" in settings I usually find some system processes or other background apps (Viper, PowerAMP, Easy Battery Saver) that are restarting and taking up my RAM.
I've trying whatever came to my mind and I don't have any idea. Stock ROM, other ROMs, no system-messing apps, no root, new recovery, no tweaks or many of them. I just don't know what else to do.
Your help would be very appreciated

Angry Birds performance

So I downloaded Angry Birds, one of the first apps any android used would download.
Now that I've reached some of the more complex levels, it looks like the P500 cannot keep up with the larger number of falling objects, and the game ends up stuttering/framing.
Is this normal? I had read that the P500 can play the game with ease.
I'm on the stock 2.2.1 ROM.
You could try and enable hardware acceleration. You might get a slightly reduced battery life, but angry birds might run smoother..
With stock ROM, it is normal. You can only experience better performance with a custom ROM with hardware acceleration enabled, a bit of CPU overclocking and a kernel that minimizes the touchscreen lag bug.
In my particular case, even with all these "goodies" I can't really enjoy the game: the stuttering is not completely gone and makes ending the level with 3 stars very difficult. But it's a lot better than what you experience right now with stock ROM.
There's a trick to that, even without overclocking, custom ROMs and kernels, etc.
When a laggy level begins, wait for the lag to stop. There's a lot of physics going on when you start a level since it has to reposition the blocks and stuff. Once they're not moving (no more physics stuff), the lag stops. Then you play the game. Just wait for a while and it'll be smooth. Trust me on this
^I've also done that, and it works pretty well.
But on some of the really complex stages in the latter parts of the game, even using this trick in conjunction with the void ROM and hardware acceleration doesn't help. We're pretty much running into the limits of the hardware, and there isn't really anything we can do about it. That said, I'd love it if I were wrong.
Yeah, kpbotbot, done that too. The game kinda demands it, but it's not enough. The amount of time that gets wasted waiting for things to settle and game to move fluid ruins the entire experience.
I know. I recently uninstalled the game Last level I was on was the one with the boomerang-ish birds.
Relevant note: A PC version of Angry Birds was out last month. No Linux version, but WINE runs it pretty well
I am actually enjoying Angry Birds with void + hardware acceleration + touchscreen fix. If you have a Class 2 memory card, Angry Birds may have installed to you SD card directly and the card's speed may be slowing the game down. Move it to the internal memory.
Also, wait until after the initial lag to play. This matters a lot since not waiting causes my phone to freeze up.
HW doesn't really do much in-game . Believe me on this one . You're better off just oc-ing your cpu to at least 768 and also try to have as much free memory as possible
Cheers.
Yeah, just like some people said and it sounds like were asking too much, but just try to be patient and wait til the game loads all the physics then the lag might be gone. Sometimes i move forwards/backwards a few times then it disapears, or even calling the menu once and then getting back.
try mik's kernel
Or wait.for the lite version.
i've noticed a bit of lag too, being patience definitely helps.
Whats this lite version all about? any changelog available?
I don't think it is the fault of the hardware. My old iPhone 3G played angry birds no problem, but generally it was a lot slower than my O1.

[Q] Phone Will Lag After Continuous Up Time...

Hey guys... I feel like I cannot keep the phone on for more that 72 hours continuously.
I'm using Galaxy SII, G version (I9100G). Currently everything original (no custom rom/kernel)
I believe that most of Android phones have the same problem.
After 50 hours++ of up time of the phone (I mean the phone keeps on for 50 hours), The phone will become noticeable lag, but just a bit, not too much. One of the best evidence is in the game Fruit Ninja. I will feel the lag everytime I slash the fruit.
I'm sure that most apps is closed (except background apps like samsung keypad) and my battery usage graph is in straight horizontal line (without any optimize software, only with BetterBatteryStats). Only 500 - 600MB of RAM is used and I think this is normal.
After I restart the phone, the phone will become smooth and the RAM will be 300 - 400MB used only. Others do not show any difference.
And sure, the phone will repeat the same problem after some hours.
I wish I can keep the phone on continuously and no need to restart it frequently just like normal phones.
Can someone share some experience about this?
Is there any solution for this?
Or this is the nature of Android?
Can Custom ROM solve this?
Your best bet is to use an app killer program so you can close anything and everything running in the background.
Holy... If you mean task killers, I can tell you that it will not work, but will make the situation far worse for Android 2.3 and up...
I use one that's built in to the ROM that I use and my phone runs great for days on end.
I'm using Memory Booster (RAM Optimizer) as my first experiment to solve this problem...

(Sola) (Q) RAM Usage on Gingerbread?

Yep, this is still a problem.
I just noticed my that Sony may have been right in directing me to check available RAM on ICS. I have a tiny amount of RAM available and had to delete many apps, still the phone doesn't run smoothly.
Anyone here still on Gingerbread? What's your available RAM like? Roughly, how many apps do you have installed? I may switch back, I've had enough.
I can see why this happened:

Flashing time maybe

We do not have the same phones so i do not know if the following is relevant or even possible for you. I recently flashed the ics333 rom with a semaphore kernel on my Galaxy SI and it really flies. If i have understood correctly the semaphore kernel frees up extra ram. I now have on average 140-170Mb available instead of 30-60Mb It makes such a difference. even games like Temple Run which i could not play before work without lag.
You should maybe consider flashing an optimised rom, if available.

A better kernel, or simply a custom ROM, I appreciate your help! :victory:
I came back from my first trip to Paris and my camera app kept freezing, it drove me crazy. I'll definitely look into the kernels.

I just switched back to GB stock ROM (184 kernel) after having tried ICS stock and xICS Hybrid ROM. In both the ICS based ROMs , I found that the battery usage is quite high (both normal usage and standby) . Also the phone started freezing after a certain number of apps were launched. I face no such issues in GB Stock ROM and it is quite fast too. Also Sony has done a good work wid UI esp. Gesture based typing and word predicition(which is quite accurate)
I have around 12-15 apps installed and I use most of them regularly yet I always have around 90-120 MB of free RAM and I have never run into issues with free RAM as such.
Also, while using ICS receiving a call used to be laggy esp when you are in middle of something and u get a call but GB is quite good in that respect. So I can safely suggest GB is well suited for Sola . Go for ICS only if you need a feature specific to it or if you are too crazy about new UI. Hope this helps a bit :laugh:

That really helps, thanks! :good:
I couldn't remember much about RAM usage on GingerB but I knew that I didn't have that freezing problem with apps or with phone calls etc. On ICS, I checked my RAM and it was constantly around 20MB, I never imagined I'd be the person that installed too many apps for the RAM to handle. I think Sony made some poor decisions re: RAM and OS upgrade.
Thankfully we can backup our ROMS so easily so I think I'll go back to Gingerbread.

Juts to add to my last post, After switching back to GB I found that the battery usage (on standby ) overnight dropped to 3% from 30-40% in case of ICS based ROMs :laugh:

RAM

Is it just me, or does the phone use a lot of RAM? Mine seems to be using 2.7GB minimum at all times. Seems high.
Higher would be more ideal. The Windows mindset of "I'm running out of RAM!" doesn't get you anywhere here; in Android, empty RAM is wasted RAM. My Droid Turbo averages ~1.8gb used of 3gb. Seems Nougat tries to average 60%-70% usage.
When you switch out of an app, it's moved to the background and (usually) suspended, but kept in memory so you can switch back to it quickly. It's things like this that take up memory you think should be "free".
In the event that you need to load up a big app, stuff running in the background is quickly and gracefully unloaded.
Unless you're getting constant foreground app crashes - which might indicate that something is forcefully keeping itself loaded and starving everything else of needed memory - you shouldn't worry about it. Android is fairly good at handling memory these days.

I notice this issue more on custom ROMs than stock firmware. On mine and my wife's Quarks (3GB RAM, as you well know), running Marshmallow and Lollipop versions of the same ROM, something causes the phones to just freeze up for about a minute, crashes, then RAM is released to use. It was happening at least once a day on my phone, then my wife said it was happening to her phone. (Our old phones, not the new LG V30 phones.) I've messed with the LMK settings, trying different combinations, to no avail. And I did report it in the Nougat ROM thread for that phone. (Marshmallow ROM thread no longer has support.)
So, while I totally agree with your answer, it is the technically correct answer, I do understand the OP's concern. I've gotten to the point where I like to see more free RAM, so I know my phone isn't about to freeze up. At least on my old phone.
I love custom ROMs, but the past couple of weeks it's been nice to run stock on my new LG V30 and have a very fluid experience. I've not disabled anything. I saw some others disable stuff and then got lagging. I've not touched a thing and my phone is very smooth.
Could a "theme" downloaded from play store take up a lot of RAM and/or slow things down, too?
This is my first experience with a theme.

Possibly, but probably not. From what I've seen, LG themes seem to skin far less than say, substratum does, and even substratum is pretty lightweight unless you get into transparent themes.
Keep in mind the default theme is itself...well, a theme. You're not really saving anything by staying on it. If you see a skin you like, use it, if you're really worried use one of the LG-provided ones that come with the phone.

Interesting. It does seem like stock ROMs tend to be more conservative with RAM usage, whereas custom ROMs will have less aggressive minfree settings in order to keep more stuff loaded up. "Unused RAM is wasted RAM", but only up to a certain point; in my experience (Maserati with its ancient kernel as well as Quark) approaching ~100mb of free memory in LP/MM/N can bring things to a crawl, and pushing it can cause a kernel panic :good:
The only issue I've seen in Quark RR has been with the Pixiv app, though, and it does exactly what you said. But...I'm fairly certain the app itself leaks memory, as it only happens after browsing a while and is perfectly fine for another stretch after it OOMs and restarts.
My experience with stock ROMs in the past - Quark included - has been "smooth but lacking in features/customization" --- I've never really understood the complaints that stock is slow and claims that custom is blazing fast in comparison. The OEM has a decided advantage in that they have all the tools they need to compile the ROM properly, with then-current driver and kernel sources and a deep understanding of the hardware...I'd be really surprised to find a stock ROM from the last few years to be slower than custom.
But to be honest, my sample size is pretty small. *shrugs* I stick by what I've said, though, if anything the V30 doesn't use its memory enough; some people have complained about apps popping out of memory sooner than expected. LG is still putting out updates too, if a memory-management problem is found, hopefully they'll get right on fixing it.

The temperature of my phone is really really hot ! 42°C+ for a simple task. HELP

Hello,
Since, two weeks now, my OnePlus X had a troubleshooting. The temperature of the phone is really high when I use it for simple task like browse the Internet (Chrome / Edge / Firfox) or Whatsapp, SMS, etc. And when I try to play at a simple game with no 3D stuff, it's almost impossible to hold it in hands. This is really really hot ! Battery at 42°C when I use any app like Whatsapp, Chrome/ Edge, etc. That's super hot !!
What's the problem ?
I'm on a custom ROM, the one of @psychem (Lineage OS 17.1). Before that I was on YumeMichi one. But the problem was already on that build.
I think the main reason for this is the battery. The phone's battery will get hotter after 1-2 years. It will run cooler if you change the battery.
I have the same problem but it's not because battery, my phone heats up at upper side of phone where the SOC is.
Me too, at upper side on AospExtended-v6.7-onyx-20200321-ROM. Not on RR-O-v6.2.1-20181124-onyx-UNOFFICIAL-fatal I used before :/
Me too.. this is on top of the top where the temperature is really hot !
I think I will be forced to change the phone for a Xiaomi Poco F2 Pro or, Mi 10 Lite or Realme X2 Pro. When I 'll have money ^^
OnePlus is not really the same company right now.
Same issue, since maybe 1-2 months now. Still running ResurrectionRemix 5.8.1 (Android 7.1.2).
I just replaced the battery (labeled 2015) by a new one (labeled 2019) and the issue is still mostly the same. The battery is obviously lasting longer now and doesn't drop steeply after falling below ~50% like the old one used to, but the SoC ist still heating up a lot in the top left corner of the phone.
Since you mentioned that you've tried LOS 17.1 and other ROMs by YumeMichi, I won't try to test other ROMs for now. If the issue is already present in different ROMs, I suspect it might have something to do with recently updated apps / frameworks, so maybe some Google apps or Google Play Services.
Looking at htop in root-mode termux (tsu) there seems to be a lot of CPU activity all the time, but not necessarily a super obvious culprit that's steadily using a lot of CPU. But I think I see a couple of GoogleQuicksearchBox processes appearing much more frequently than usual and some of my regular apps seem to start new processes a lot, as evidenced by the same app name frequently re-appearing under new PID numbers. It also it feels like I'm running into low memory a lot more now, because apps have to reload more frequently when I switch among them, especially Google Maps and apps that use the Maps API (like rideshare apps). So I suspect that something is causing apps to frequently close and start again, perhaps by using up too much memory.
Is anyone making similar observations?
