[Q] Phone reboots during games and now stuck in reboot

I've encountered an odd problem on my phone recently, only in the last week or so. It first started while using Myn's Synergy RLS1 and playing Plants vs. Zombies--my phone started to stutter/lag a bit, then rebooted back to the 'Synergy' flash screen. It got stuck in reboot, so I pulled the battery, did a wipe of the cache/dalvik, then rebooted and all was well.
Thinking it might have been a stress on the CPU, I installed Synergy+Godmode (had been using it a few days before for about two weeks with few issues). This worked pretty well until last night when it stuttered again, then this morning while updating my apps from the Market the phone rebooted again, and this time no matter what I seem to do I can't get it back up.
I did clear the cache/dalvik and got it to load up Android, but the phone application kept force closing so I couldn't do anything and had to reboot again. Since then I haven't been able to get it back up.
I can access the Recovery (obviously) which is a plus, but I can't get anything else. I've waited for an hour and now it seems stuck on the white "HTC Evo 4G" screen.
I'm thinking I might just have to reinstall the OS, but I'm curious why this is happening at all.
Could it be that I have too many games installed on my system? I have a 2GB SD-ext3 for games and applications; is it possible that too many are trying to run in the background and it's overloading the RAM causing a crash/reboot?
Any thoughts or suggestions on how to avoid this in the future would be appreciated. Thanks!

yeah, I have to clear the stinking ram EVERYTIME I play a game or it slows down. our phones really suck. wish there was a ram upgrade option. lol. or is there? :-D But I'm going to wait for the quad core processors for our phones and get one at that time. cause they should have at least 1GB of memory instead of 512 like ours. ACTUALLY I HOPE they put 2-3GBs of ram in our phones! that would be nice!
oh btw, you should ALWAYS USE A CLASS 10 SDCARD! trust me, it does go faster when you store your games and such on it.

I actually have a Patriot 16GB Class 10 SDcard. It is very nice and a definite performance increase. But I'm still having this issue.
I did just wipe/reinstall the ROM, so hopefully it doesn't come back. Although I am sad to lose ~3 days worth of stuff I did on my phone. (Last Titanium backup was Sunday)

[Q] Rebooting to keep things fresh...

Im coming from a D1 that i had for 2 years and was rooted and rom'ed up since day one. With the D1 most people including myself would reboot their phone once a day to keep it fresh and (lag free) Atleast, for me after a day or so i would notice some slowness to it....But with the G-Nex there is no slowness ..its snappy everytime i use it..havent rebooted it in 4 days and it doesnt even blink...So my question is...is that because of the difference in RAM between the phones? or does anyone reboot their phone as a daily routine still?

Most likely.
With 256mb, ram has to be watched, and a memory leak is fatal.
With 1gb, not so much. Of course, Android has also improved quite a bit since the D1 days.

LOL...Fatal is an understatement! Especially running Gingerbread...

Most of us dont reboot. I go about 500 hours of uptime on average and the phone is just as solid. No worries.

I rarely if ever reboot my Nexus, I only did initially when I had to add the AT&T HSPA+ APN, definitely a smooth and speedy experience.

It wouldn't hurt it to reboot... IMO. I haven't reboot mine in a few days now and see no problems. I do occasionally pull up the multitask menu and swipe out the apps that I know I won't be using anytime soon. Maybe there is a better way to do that... but either way... rock solid without reboots. I came form an OG droid to a Gnex as well (what a difference that was).

I've gone up to two weeks without rebooting with no lag. I finally rebooted when the keyboard stopped working. Before that, no lag, no problems at all, and the keyboard was fine again.

[DISCUSS] Why are background apps closing so much more quickly?

Currently running: CM 10.1, build 0319 stock kernel and cpu settings.
TL;DR - The Hercules and its 1GB RAM suddenly seem like it can't multi-task like it once could. However maybe its app developers just heinously demanding more resources so their apps can look amazingly fluid because they forcefully killed everything else in the back?
What's the deal?
I remember a time in yesteryear yonder, whence I would have 5-7 apps running in the back without breaking nary a sweat. SO WHAT THE HELL happened Android? That was back on Touchwiz and Gingerbread!
Today I can't have utorrent and chrome open simultaneously. TWO apps. For instance if I've utorrent downloading, ill switch to Chrome (recent apps switch; not open) and maybe answer a Whatsapp immediately after; utorrent will undoubtedly be killed and must be reactivated.
Now I understand that chrome and utorrent are naturally RAM heavy applications, but it helps further my point. Why are apps being killed so quickly today? Was it Touchwiz that was great at ram management? Was it gingerbread? Or have apps been slowly updating over the last two years and demanding more allocation of RAM from the get go so that everything else gets forcefully killed? I remember when the Hercules was announced and all the reviewers claimed 1GB was such a stupid amount of overkill RAM and we'll never see it taxed. Now that 2GB has become the standard with the introduction of the GS3, I theorize app devs are being more liberal in demanding resources from devices without giving too much consideration for older models. So apps are killed more frequently to make room to the foreground.
So why do you care?
-The stock stopwatch app will die if you run a few more apps afterwards. This is just derp. Really, try this yourself. Can you imagine your morning alarm was silently force killed because you were reading a website before bedtime?
-Some audio apps can be killed as well. ie Doggcatcher. Audio actually stops if certain conditions of apps are opened after Doggcatcher. Derp.
-Device slows to a complete crawl during the course of a day. I don't believe I've ever owned a device (clamshell Sammy, Blackberry or Android) that didn't exhibit facepalm-worthy memory leak issues. If Android was designed to have its RAM filled, why do slowdowns exist?
-Incoming phone calls suffer lag when re-acquiring attention. This seems bizarre because in About > System you can see the Hercules indicates it has 768MB RAM, indicating a quarter is reserved for system apps. Which means it shouldn't really have this problem.
-Application settings requesting 'Persistent Notifications' to ensure app foreground attention. Apps like Tasker, utorrent, Battery Guru request this to remain alive. Is this the solution now? And is this 100% immune if system requires the resources?
-Apps take longer to open. I can't quite pinpoint this. Just a feeling.
Alright man relax, the Galaxy S4 and HTC One come packing with 2GB
Upgrading to a new flagship doesn't seem to be the solution to stifle this issue. App developers are excellent at what they do and naturally want their product to look its best with the resources available to it. With 3D games exhibiting the capabilities of a Snapdragon 600 and Tegra 4, where's the incentive to tell either to slow down? This same logic can be directly applied to the smartphone spec war and the recurring battery life bottleneck story.

So what's your point?
I'm not sure I have one. I'm just observing whats happening. We are finally actually seeing applications that are pushing our hardware to its limits. While 1GB of onboard RAM used to be a drool inducing spec, 2GB is not really a huge leap considering the jump the Snapdragon S3 made to the S4, S4 Pro and now the 600 in magnitudes of processing power. 2GB would certainly be astronomical, if it took a trip back in time and only had to run 2011 apps. I guess my point is: I'm throwing a tantrum that the Hercules is showing its age, even if it's not its fault.
Forgive my rambling and lack of proof-reading. At work.

lol...I totally agree. My apps seem to close a lot quicker, yet my RAM never dips below 280 MB free. Don't really get it myself...

Issues with my S9 battery and RAM

Just picked up the S9 (Snapdragon 845) on launch day. Coming from a Oneplus 5.
My battery life: https://imgur.com/a/nfeCR
It seems really bad. It's less than 1/3 of my old phone.
I checked for wakelocks. Seems to be just playing music on Spotify through my car and that's it which is normal.
And I'm seeing some really weird RAM issues.
I will clear RAM by optimizing the phone, and open just the phone dialer, Gmail and Messages.
After the third of these apps opens, the first one will need to be refreshed when reopened. If I open something like Reddit or Chrome as the fourth app, all 4 apps have to be refreshed.
This phone seems unable to hold more than 2 apps in RAM. Sometimes I can't even have more than 1 Chrome tab loaded. If I switch between Chrome tabs the other tabs need to be reloaded. I don't even think my old Galaxy S3 had this problem.
It does get better after a restart, but a few hours later it goes back to the above described RAM issues.
I have to be doing something wrong here. Anyone else have these problems?

I have the exact same issue with my S9 Plus (Exynos)
Can not keep more than 3-4 apps in memory without them all restarting after opening then up again having almost 2.5GB usable RAM left. Have checked going to developer options and checking for limiting with background apps but the option is set to stock. (unlimited)
This phone is not even 4 months old and im starting to hate it as i use it heavily even for work. Going to talk with Samsung for a repair or replacement when I'm still on contract and warranty...

You should take your phone to Samsung to repair your phone or replace it, I have this kind of battery life, but I own an Exynos galaxy S9, you should have so much better battery life since yours is the snapdragon version.
I don't have these RAM issues, I just see high RAM usage sometimes when I use google camera heavily, but I'm deleting it...

Tab S 8.4( SM-T700 ) is very slow

Hi guys,
I've been having this tablet since almost 5 years, at the beginning it was very fast. Fast forward a few years I noticed it has slowed down a lot ( very laggy when playing game like it was lack of ram), it's very hard to navigate on chrome on certain websites, it's so slow that I just stop using it sometimes. I was looking forward for the Tab S3 but it's out of my budget right now. I've tried to format the tablet twice with no success at all. I have developer mode enabled. I've tried to put the animation time down to 0.5x, it hasn't change anything at all. I was wondering if there's anything I could do before it joins the graveyard. I love Samsung products, I'm using a S9 right now and I have the galaxy gear S3 as well but this tablet is killing me.
Thanks

Have you tried a factory reset? deleting all cache? removing unneeded apps? check to see how much ram is being used directly after reboot to see if some apps that are loading can be removed and loaded only when needed?
There are a lot of things that can cause this. I'm running los Nougat on mine and it's perfectly fine, no issues, very responsive.
One thing I'd suggest is don't use Chrome. It uses a ton of memory. I'd suggest switching to los Jelly browser, it's very bare bones, as a browser on a tablet should be.

Hi,
I did try a factory reset along with deleting the caches, I have to take a look into my apps though, I have maybe 800-1gb of ram free when rebooting. I use Nova Launcher hence I pretty much have the same setup than on my cellphone. By slow I mean by example when playing 8 pool, when I hit the ball it move slowly exactly like the tablet would ram. I recl seeing that on my old PC back in the time when I was lack of ram, lol.

I have the same tablet as well, perhaps I shall try a factor reset one day.
It's hard to believe newer tablets will run faster, while the specs aren't that significantly higher. Not much more ram, processor not much faster.
It's almost as if they've deliberately slow down the device as it gets old (like that Apple scandal a while back), but I'm sure that's not the case here, as XDA guys would have dug out that dirt pretty quickly.
I shall try out a reset, and see if it's any better. My last resort will be to replace the battery, I've ebayed one a while back, but never gotten to use it yet.
I will try out a different browser too. I do agree Chrome has gotten quite fat lately. Looking at the Chrome task manager on the desktop reveals some scary amounts of memory used.

Removing the sd card helped me a lot

Removing SD? Wth? If that's the solution, it can go as well to the garbage.

Same here, I just getting this second hand Tablet 2 weeks ago. The Tab is in 99% perfect condition. All running good. It was running stock 6.0.1 MM. Then when i'm trying to swipe the home screen, it's lag and the lag is very noticeable. Then, I'm thinking "Why is this device very slow even they have a high spec?". This is the first time i use this tablet. The reason why i bought a second hand is because, i can't afford Galaxy Tab S2 or Tab S3 and i'm such a poor guy so the Tab S 8.4 is enough for me ?. But, i know how to tweak it better so it makes the CPU awake like before they come. That day i downgraded the Tab to Stock Kitkat 4.4.2 and i never forget to root it. After that, installing eRobot rom v.3.1 Stock Kitkat and also flashed Skyhigh Kernel which is gives you a powerful control of device CPU/GPU. After finishing the setup. and setting up the Skyhigh Kernel(Overclocking CPU/GPU) then reboot. After rebooting, my Tablet come to fresh again and it fresh like new ?. The CPU comes awake and performance always on. But, the powersaving can't really do anything and the battery may drain faster if you're a heavy user. Thank goodness there is still people developing the Kernel. I feel better now. I'm using this Tablet mostly for editing pictures, search information, and listening to music

I also bought it second hand but in my case it is to watch Netflix series on hd with that magnificent amoled and the truth is that I am very happy once I have changed the battery. I'm on android 6 official. The only solution for the tablet to run well in official marshmallow is using the disable package that makes it very usable, a real improvement but for my use the battery lasts 20% more without freezing anything from Samsung, this costs to understand for me but it is like this. For multimedia this tablet is spectacular and that is my use, especially thanks to the 16 10 format, it is ideal. The S4 I do not like, it's very big and very expensive. Long life tab S of 8.4 hahaha ???
