[Q]Have to Clear Cache and Dalvik Cache after every power off

So I am having a really strange problem recently with my phone, was wondering if I should unroot and return it or if it is something I am doing wrong. Basically what it boils down to is if I power my phone off from the menu or pull the battery, etc. upon powering back up it just Hangs on the HTC Evo 4G white splash screen indefinitely. I have let it sit as long as 15 mins without booting before, having seen this before in the past I know not to panic now but I just reboot into Recovery and wipe my cache and dalvik cache every time I reboot and my phone reboots back into sense in no time at all.
I know this is not normal, is there something I can do to troubleshoot this problem or is this is a sign of hardware failure?

I've never seen that before. Interesting. What rom are you currently using? Do you have an unusually large amount of apps installed? The first thing I would do, is make a nandroid backup of your current setup, and then do a full wipe and flash a format all.zip, then reflash a different rom. Or just simply restore a nandroid of a known good setup, and see if the problem persists. If it stops, I'd say it was something specific to the rom/kernel/setup that you were running before. If it continues happening on a clean install of a different rom, then I'd probably unroot, restore to stock, and then see if the problem continues. If it does, take it to Sprint. If it stops, and everything is fine, re root it and start over. That's just what I would do, but I've never been presented with an issue such as that.

I appreciate the advice, I'm running Sprint Lovers right now been running it for a few months now, I don't have an unusual amount of apps installed but I did notice that the problem seemed to start occuring when I changed the Kernel. I will try your advice and see if that fixes the problem. I've been wanting an excuse to try the new Gingersense rom anyways.

If it started happening right after you swapped out the kernel, that could be the culprit. If you want to try the gingersense rom, I'll all for it, and will tell ya that they ran super incredibly smooth for a factory rom. However, if you don't feel like changing roms just yet, maybe try a different kernel. I'd be suspect of that, if the problem started shortly after changing to a different kernel. I say try out a gingersense rom, you shouldn't be disappointed (unless your phone still hangs at the splash screen upon reboot, lol).

[TROUBLESHOOTING] Reboot... Reboot... Reboot... Arghhhhh

I've been having a problem with my phone hot rebooting every 30 seconds to 5 five minutes. It's driving me up the wall. I can barely even use it, since half the time I have no data, and the other half by the time I can get anything open, the phone is rebooting.
I've tried:
- Changing ROMs (Juggernaut 2.5 to 2.6 and back to 2.0; Bombaridier; EagleBlood; Streamlined)
- Changing kernels (stock, Jugs, Bullet, whatever kernels come with the ROMs mentioned above)
- pulling the SD card
- formatting the SD card
- fixing permissions
- factory/data reset, wipe cache, wipe Dalvik every time I flash
One thing I did notice... the last ROM I tried was EagleBlood, and it was fine for half a day. I charged it overnight, and, thinking my problem was solved, I decided to calibrate the battery. After wiping battery stats, it's rebooting over and over again.
I just unrooted and took it back to stock to see if that does anything.
In the meantime, any ideas? Please help... I'm getting ready to tear my hair out.

normally the reboots are due not Wiping, but you did say, you Wiped, so it should be fine
did you OVER Volted the CPU at any point?

No. I overclocked and undervolted when on Juggernaut/Jugs, but at no point did I ever overvolt.

how aggresive were your overclocks. because that could be the problem itself
or if the kernel is undervolted and the cpu's dont like it .

Max 1.89/min 384 and UV -2500 when on Juggernaut, but after I started having the problem, I didn't even install SetCPU anymore. When I was on EagleBlood, it wasn't OCed or UVed at all, didn't have SetCPU installed, and it still rebooted all the time.

OK, I've been unrooted for a couple of hours and no rebooting. But being unrooted sucks! I don't even want to think about re-installing all my apps without Titanium Backup.
So I just Odin flashed CWM and am flashing the SGH-T989 // UVKID // Stock // Deodexed // Rooted //Busybox ROM so I can at least run TB and get all my apps back. Then we'll see what happens.
I'm afraid to calibrate my battery though... Haha... I think the FIRST time I started having this problem was after a battery stats wipe. And then after running EB with no problems for several hours, after wiping battery stats... BOOM! It started happening again. But why would wiping battery stats make this happen?

your using CWM for everything? or RM?

CWM. I've never used RM... Should I?

OK, after restoring everything with Titanium Backup, it's doing it again. So it's gotta be an app... right...? How on earth do I figure out which one?

this is why i never use Titanium backup
your going to have to install each app one at a time to see which is causing conflict

I just have the same problem, keeps rebooting basically every 30 seconds to a minute... and it is not rooted, no new apps but I did update the firmware via Kies in the morning, it only started rebooting in the middle of the night, had to shut it down to be able to sleep.
No idea what to do...
The phone is useless as it is.
Any hints are welcome, thanks.

Note 3 keeps on black screening/freezing/random reboots

Hi everyone. I have a sporadic problem with my vanilla note 3 from t mobile. Its a totally random occurrence but sometimes it will freeze(loose all input functionality) sometimes it will just stay black screen(no input taking) and usually (not always) it will reboot itself after this happens(sometimes a battery pull is required). Is this a memory leak issue? Thanks for any help. Sometimes it will run fine for a week or 2 and then all the sudden it will start acting up.

Was it rooted? I had a similar issue before mine was rooted, some of the system load programs that I didn't use would start up and then grab all resources. ..

Mine was doing the same thing while rooted with towelroot. Even after I unrooted it was doing the same thing. I didn't try a factory reset, but T-Mobile is sending me a replacement phone.

If it was my phone I would do cache wipe first, if still no go then full factory reset and I would then reinstall most important programs first.
Restarting phone every few days is not a bad idea on it's own and BTW when was the last time you cleaned garbage from it?

Random reboot?

So, I've had the premium for almost 3 weeks now. On the second day it crashed whilst I was listening to music +browsing in chrome. Thr screen turned inky and then turned off. Since then I haven't had anything similar happen, but I have had 1 or 2 reboots. Are these signs something could be wrong with my phone? I have like a week to get a replacement. It's rev 2, other than this I have no complaints.

Try to remove cach in recovery mode, maybe that will fix your problem. If not let me know

This has been happening to me as well and actually results in boot loops. Since I have Liveboot, I can see the dmesg output. It says "Failed to start system services. Invalid abi: ABI" or something like that. I'm RomAur so maybe that has something to do with it?

It has happened to me 3 times this week. Also RomAur 1.1. It seems to happen when i am heavy multitasking, definitely related to chrome I think.

I'm completely stock... I use chrome as my main browser. The last time it happened it froze on wake whilst it was charging... The first time I was listening to music and doing something else which I can't recall. The phone has 3gb of ram so I don't really clear my recent apps as often as I did on my S4. It happens once a week on average for me. Cache wipe didn't do anything.

You could've easily gotten a faulty device. A but load of hardware issues can do that and I would advice you to do a factory reset, update to the latest F/W (flash it if not available in ur region), see if it happens again and if it does - get a replacement
Gd luck

If you're totally stock this might not help but I narrowed my problem down to xposed being unstable as crap on mine at least. Hasn't happened since I went back to stock fw (using. 200 generic FR). But I tried to install xposed and I got the three light reboot immediately.

exactly like that on my z5 . when i flash the xposed uninstaller , it doesnt randomly reboot, but when i flash xposed , it does.i was thinking of flashing .200 ftf and then flashing xposed from the beggining (before i install any apps ) to see if it helps , but you said you did it??

Robin randomly rebooting

Anyone have issues with their nextbit Robin randomly rebooting?? I'm on stock 7.1.1 and it reboots on me multiple times a day... Tried a hard reset and clearing Android cache nothing helps!!

I'm not doubting you, but are you actually seeing it reboot? I had another phone do the same thing on Nougat, but it was only "acting" like it was rebooting. I would put it down and after 10 minutes it would say I have to enter my pin after a reboot. I haven't experienced it on the Robin (yet), but the only fixes I found that work were a full wipe & reinstall then installing one piece of software at a time from my Google Library or installing a custom ROM.
Sent from my Robin using XDA Labs

I'm going to definitely try unlocking the bootloader and a reflash maybe even try a different image . Yes it is most definitely rebooting, seems if memory get full having to many apps open it reboots, I've had it reboot multiple times when I was actually using it, during Google maps, chrome and even Facebook.. I've even tried deleting certain apps but it still reboots randomly....

Bumping this, because we have one doing this now. It's been fine up until probably a couple weeks ago. Seems to be under moderate use. Wife's phone. I've seen it happen, too. It locked up, wouldn't respond to any input, then it did a full reboot. She says it happens at least once a day.
Using LOS 14.1.

This could be due to battery degradation.

Happened to me too. Stock rom. Reboots 3-4 times a day. Now all of a sudden it got stuck in an endless reboot cycle. I posted about that in another thread

Now mine is doing it, too. If it was the battery shouldn't it show with the discharge rate? They can show a full charge and still do it. Can even do it while charging. Mine just now did it while charging. Didn't get hot either. Just locked up and rebooted.
