Is it good to be switching roms frequently? Can it mess up your phone?
As long as u do it correctly each time u should b fine....but obviously it'll b hot if u flash too much....
You can flash as many ROMs as you wish with no worry, it won't cause any hardware problem more than using it a lot during the period you would flash (I mean that gaming 10 minutes is as bad as flashing a ROM for the device) so there is no problem. You will just be wiping quite often to keep it running smoothly.
Actually flashing a rom only formats different partitions which the memory is made for as it is made for read/write files. There is even almost no CPU usage I think since roms are simply zips extracted to the right partitions.
Happy flashing

Actually memory tends to wear with constant formatting and writing, but once he doesn't flash it every five minutes for the next couple months, it's gonna be fine.

Okay then It's different of regular HDD we find usually in computers. True that we don't call it ROM with no reason but I remember I read an article stating that the actual drives used for ROMs are supporting thousands of writes... But with a little calculation once per five minutes for a few months makes kind of 60 000.

I'd love to continue the discussion, but if we get too in depth into this convo, some users may get scared for no apparent reason, so I'll leave them with your last words.
Hello guys.. I'm a flashaholic.
The reason i'm here, is because i've just realized, that i haven't had my quick fix for some time now..
Everything seems so stable, except the *mic* issue, but hey, i fixed it with a hands-free.. Otherwise, i'm very happy with my phone, it works, it doesn't use up that much battery, and it doesn't crash, you can even do normal stuff to it.
But to the point.. I really, REALLY miss AOSP, especially the theming.
I can live with the occasional bugs, though i wish it could be at least somewhat stable.. *You know, im not that picky*.
But the one thing that keeps me from using AOSP; is the camera app from Sony, because i like taking pictures of my son, and the environment..
Are there any Camera app out there comparable to the Sony equivalent?
Oh, the urge..

I have the same urge, I wanna get the full output from my Xperia Z2, feel all those four cores working in my hand. But that one Sony Camera app stops me because it's beautiful. It's matchless. That's the only reason I'm not changing my ROM and be bound to what Sony's put in my phone.
I am in the same boat here! I want to flash PA so bad especially with all their features but then the camera app, the noise cancelling features and x-reality etc is really stopping me from doing so
i use to be in the same boat before i noticed there is no point to flashing roms when im on a rom which does what i want
perhaps you should find a rom which has what you want
Same here.I literally used to flash a new ROM on my Nexus 5 everyday. As has been said though, the stock Z2 ROM does everything I want it to and rooted with some xposed mods its perfect.I just have to learn to live with my phone the way most other people do.
just a note
formatting then writing a rom to your system slows your device ALOT, it also cause alot of other issues but that comes after long wear n tear

Does this include doing a clean install? I mean doing clean install also slows the system? I've done clean install (re-install the stock Sony Z2 ROM) for 3 times till now. (Via Sony PC Companion)

I remember reading somewhere years ago that flashing new firmware over and over will eventually wear out the hardware and cause it to slow down/eventually fail. I can't seem to find anything for this when searching though! Would it be possible for you to shed some light on what I should be searching for or what causes this issue?
Thanks in advance!

there is something called read/write cycle life
you can only write info so many times onto a disk before it wears out and stops working
formatting a partition takes a huge amount of cycles, installing roms does the same too because its alot of data that has to write

Cheers for the reply! From what I read on the link, it says most flash memory have a P/E cycle of around 100,000 and from what I can remember, it varies depending on the type/quality of the flash memory used (Nexus 7 2012 had rubbish flash memory which a lot of people complained about). Just going off an assumption that the Z2 has a P/E cycle of 100,000, wouldn't it take quite a lot of ROM flashes before the memory deteriorates? Or is it more due to the size of the data being written/erased than the amount of times it is being done?
Sorry for the questions, I know this isn't the thread for it but it is interesting to me!

I used to flash a lot roms everyday on various devices. I didn't notice any side effects of it. As I know a little about hardware there is nothing to fear. You can imagine than one memory cell is one bit of data. If it withstands 100 000 writes it literally means that you can save data (eg. flash rom on it) 100 000 times. There is no way that you can cross this number even with everyday flashing. And it doesn't matter how much data we are writing because each memory cell deteriorates individually, so if we write on 1000 cells it means that every cell will deteriorate only by one write operation which means every cell will still be able to be written 99 999 times.
Another thing is that the storage memory in smartphones is usually one chip which means that all your data including /system partition (which you overwrite during rom flashing) and your photos and music on /data are on one physical device. The conclusion is that if you are afraid of rom flashing and wiping you should also be afraid of saving photos to internal memory. And since we are using our int. memory and change files placed on it a lot it means that we can flash roms as we please without consequences.

Thanks for the thorough explanation. I had my suspicions this would be the case and you've driven it home by explaining the whole music/data/pictures scenario. I used to flash PA and other roms on my N4 more often than I care to count but I never once saw a decrease in performance so it's good to know (personally and for others) the phone's read/write performance is not going to be realistically affected! :highfive:

I've flashed previous android devices ( HTC magic / Desire HD / SGS 3) 100+ times each with no obvious slow down, my albeit limited understanding was that NAND chips where rated for 100k+ P/E cycles?

Correct from the wiki link provided a few posts ago:
"Most commercially available flash products are guaranteed to withstand around 100,000 P/E cycles before the wear begins to deteriorate the integrity of the storage.[21] Micron Technology and Sun Microsystems announced an SLC NAND flash memory chip rated for 1,000,000 P/E cycles on 17 December 2008"
So here is my current problem: My phone will drastically slow down when trying to multitask. I.e. I basically cant do anything when Pandora is running or ill start to get stops and skips (not connection related), and occasionally, depending on the app, the phone with freeze for an extended period, things disappear from the screen, then it goes blank and back to lock screen asking for pattern rather than fingerprint for "added security." (this is what I'm calling a crash)
Many apps will also start to lag and crash after periods of time, even running on their own. Like tumblr, meetme and facebook.
I have my CPU usage up, and idle is around 7 across the board. Once it starts to creep up above 12-15 is when ill start to get the lagging, lock ups and freezes occur around 20-30, and I've seen it spike as high as ~55 before a crash. Thing is, I'm getting lock ups and freezes while the graphical bar (the red, green, blue one) is barely moving past the CPU usage numbers.
Sorry, I'm not too sure what info to provide. This is a new problem for me. My old phone (running a 1.2ghz quad core, LG optimus G) was able to multitask better than this phone. I never had any skips or freezes while running pandora AND one of those other apps on that phone. Is this a corrupted install? Is this Octo core phone just THAT slow?! I'm not super experienced with ADB, but experienced enough to use it if need be. Any help would be appreciated.

I would first try a clean flash/factory reset/cache wipe but is there a reason why you are still using cm13 vs los14? I had no issues with cm13 but los14 is much better anyways.

Los14 was not avail when I was flashing my phone. I use it for business so its always risky to flash and what not. Never had a problem, I just don't wanna risk it. But if this is the case, may as well move to los14.

Ah I see, yeah makes sense haha
Yeah I would backup and then try a clean flash/factory reset if you want to stay on cm13, other than that, I don't know anything general you could do as far as staying on marshmallow goes.
Los14 and Los14 based roms are much smoother however and most of the bugs have been worked out by now. If you're not set on staying with marshmallow, try out some of the nougat roms :good:
Obv you'll want to backup, wipe, flash a rom, flash gapps, wipe cache/dalvik, and reboot but you prob know the drill already haha. You are on twrp or cm recovery?

Nah, I'm not stuck with MM. I like to stay with the best available, so yeah, I'll definitely go with Los14. Thanks for the input! As long as its smoother and allows me to actually multitask, I'm sold. I tend to use TWRP, but that's probably just because its what I'm used to. The interface is nice. And you can update OTA.

Hi guys.
I have had my Redmi note 4 for just over a year now and about 2 weeks ago my phone was very hot on the top area of the screen. I downloaded simple System monitor and my cpu temp was around 80 degrees Celsius. I also noticed on the app it shows my phones was constantly spiking to 100% disk writing. So I did a hard reset and restored my phone from a backup and it was fine for about a week now its overheating again with the same disk writing issue. I also noticed in the last few weeks I have been getting a lot of dropped calls on either of the dual Sims no matter how good or bad my signal was.
Any assistance will be appreciated.

I am running android version 6.0 and Miui 9.6
I have booted the phone in safe mode and it still overheats so it doesn't seem to be an app causing the issue. I also installed Avg and it didn't find any problems. The cpu usage is low when the problem occurs, the issue is that it has constant disk writing spikes which I assume is the main problem, but there is no way to see what it is writing.
Hi Sekzi, I am having the same issue as you are, in fact, I wasn't sure where to look for the problem tbh, after reading your post I checked and It is doing the exact same thing. I have the Mi Note 4 Redmi and I removed the SD card just in case, no change! Was about to look for a custom ROM to install but I would rather wait for Miui official 10 release hoping that would solve the issue. Please share any updates you might have, thanks!
I also have same issue pls someone fix this bro as fast as possible cause I can't play pubg until this will be fixed

Install greenify, Xposed framework modules like coolify, amplify

I am using Pocof1 March2019
lately,
1. it lags alot
2. heats up alot
3. freezes on touch and even applications doesn't work as swiftly as before!
now i have done the following
1. tried three different kernels after CLEAN flashing Roms such as Corvus, Crdroid, havoc , of Android 9 and 10 both and tested performance
2. device was running on Lawrun for last many months various updates on Pie rom
3. I FORMAT data and Reflashed MIUI11.0.8 by Fastboot method, clean flashing fully
4. I then format data again and changed by filesystem to f2fs
using now AEX / pie with sphinx3.1 and barely making thru day
device heats alot even on room temperature while ac working.
it is possible the cooling mechanism is deat? or thats the end of this device for me?
any sugggestions? before i go to market and start hunting for some other developer friendly device?
on same node, can one suggest me another Xiomi (LED panel only) which is very popular on xda , having many kernels and roms?
thank you in advance guys
Well if you've done all possible ts software wise, then it's likely an issue with hardware. If it's just heating issues depends on what you're doing. If you have a case, depending on thickness and what you are doing then it would cause heating problems and also if the phone overheats then performance dips.
In my case haven't had issues with the phone at all performance wise, battery, or anything else (only problem is signal, but that's an issue with my network, not the phone per se).
So based on my humble opinion, try having it checked for damages. Since it's out of warranty have a technician check it out, most technicians provide free diagnostics anyway, or if you're confident enough try opening the phone yourself, ifixit has a tutorial on it and unlike most phones it's an easy teardown. But if you're not confident look for a pro who offers free diagnostics first

You are using android 10 firmware with android 9, why ? If you use Android 10 with older firmwares than 11.0.4.0 it will cause issues and so is your case, just in reverse. Try to flash 11.0.8.0 from fastboot. Then flash recovery > AEX 7.3 + gapps. Or try Reloaded OS. It is a CAF rom so performance is great with good battery backup. You won't need any custom kernels. If no progress still then get ready to say goodbye to your poco.

You're confusing bro. As for data, why not just back it up? You yourself even stated that you've formatted, flashed and all that stuff right? So basically by now you have no internal data or you already have a backup. And as I said dude just have it inspected, they should be able to perform a checkup within the day if they aren't that busy. I've had issues before and in my country some where able to diagnose the issue.
FYI that's your problem if they can't diagnose it in a few hours, if you badly need the phone repaired then prep for it, "diskarte" as we call it, that means planning ahead in my country. Make plans and prep for it, either borrow an old phone from a friend for the mean time while you have yours in repair or something or ask maybe the repair guy has a spare dumb phone (some OEMS do that if you are in warranty anyway) or tell people not to call you on a certain day because you need to have the phone repaired.
Again, that's no longer my issue "diskartehan mo" make your own plans. I'm saying if you tried all software then it's hardware. If you don't want to go through all that hassle then just buy a new phone, simple as that

the reason why i am nervous here, locally there arent any good repair shops who can fix Xiaomi Devices. mostly go after iphones or samsungs hence i am pretty positive any repair shop person will open device, ask for something to be replaced and it wont matter
I'm on latest MIUI 11.0.8.0 with No Gravity Kernel, with NGK thermals. Performance is superb and runs very smooth. PUBG runs at constant 60FPS even on HDR + Extreme (used GFX tool).
CPU throttling test app provides results of 170K+ GIOPS. On stock MIUI kernel, this result doesn't cross 100k and even PUBG is not playable when there are many players nearby. Constant stuttering and lag.
You should try fastboot flashing the latest stable ROM and a custom kernel (NGK, ODK, Lawrun etc) to check, as stock MIUI kernel is laggy anyway. If everything is fine in hardware, this setup will provide you with Max performance.
My phone makes two years this november and it still gets 360k on antutu on same setup and never gets heated
*Changed the battery two months ago eve it didn't have any problem
