I don’t know if it’s an age thing, as in phone years = two years being geriatric or what but it’s been doing some weird stuff.
Periodically, it’ll crash. The screen will totally freeze with it either on the home screen or a black screen as though it’s switched off. Ho hum, yet another battery pull to rectify it.
It doesn’t like too many text messages so I have to regularly do a bit of housekeeping there. Related to that, typing is starting to irritate me on there. The predictive seems to have a mind of its own and, well, it just winds me up so I end up making calls instead of texting.
Some of my text messages have vanished without me deleting them! I’ve noticed texts can be located in the SIM contact and the phone contact yet strangely my SIM tells me it has no texts. Nevertheless, when I’ve decided to embarked on a housekeeping mission, I learn that messages I intended on keeping have gone before I’ve even started deleting anything!
For a while, the phone also didn’t seem to know where I was. I was and still am in the UK and a few times, it put me in Balkan. That’s great. I’m all for a free holiday but it could have warned me so I could have packed properly!
It likes to use data even when I’m not even touching the phone! Whenever I pick up the phone, I always check next to my network that there is no counter. However, often when I pick it up I can see an hour or two has passed on a counter meaning its gobbling data. What’s spooky about this is that I’m meticulous about switching stuff off that uses data and it still turns itself on! This was the whole reason I didn’t take this phone on holiday last year; I reverted to my LG Renoir because it was safer!
The last thing it’s done, just a few minutes ago is re-start itself! I wasn’t even using it; it was just sat on the table next to me minding its own business and decided to re-start. Why?
After the Balkan incident happened a few times, my Mum said my phone was crazy. I agree with her.
Has anyone else had weird stuff happen on their phones?
If you have not tried it yet I would do a hard reset. Power your HD2 on while holding down both the volume up and down buttons and follow the on screen instructions when the come up.
Also make sure to back all of your personal data up from the HD2 first as this will wipe it clean.

This made me laugh hilariously too by the way.
The earlier roms often exhibited some, all or less of these behaviors. If you are still on a 1.4 rom version, get it updated.

I’m on the original version that came with the phone. I think that might be 1.43.
When you mentioned a ROM update, I thought
I’m so overwhelmed with the information on this forum. There are so many ROMS it’s hard to know what to pick and I’m seeing far too many posts where people have tried to update and something’s gone wrong.
I just don’t have the level of understanding about phone software to carry this out successfully.
If it were as easy as it is to update my iPod via iTunes, then I’d do it but all this looks way too scary
if you want to keep a stock rom, an update is very easy. and a lot of bugs in the first releases have been fixed.
just go to the website of your carrier and download the rom in the support section. if your phone isn't branded you can download the newest version on the htc website.
if you upgrade your rom you also have to backup all your data, cause it will get lost during the update process.
you can use pim backup for contacts and messages, or just use microsoft myphone.
yea mine was mental on teh original 1.43 too, lots of accidental calls,
to get the update start with htc.com, most of the uk carriers dont bother hosting the updates, htc.com - top right, pick country, then support - select phone - downloads and change teh small dropdown from all to rom upgrade, look for your carrier, , if a rom doesnt accept your serial when you click to download it, it isnt right for your phone, and you maybe have an unbranded, meaning it would take the regular WWE (world wide english) update, in which case try the one that doesnt have a carrier name attached.
once downloaded, read THIS which is linked to from THIS, which is a list of very usefull guides and related posts.
Thank you for all your excellent replies!
I got the latest T-Mobile ROM 3.14.110.1 from HTC website and completed the update following the HSPL installation.
Those links were absolutely wonderful! Thank you so much! I also found it useful watching the Youtube videos that were linked in one of the threads.
I’m currently personalising my phone and I’ve forgotten how to add Bluetooth as a QuickLink. I know it can be done as I saw the solution on here when I first got the phone and did it then so I’m having a look around see if I can find it again.
Oh and what a pleasant surprise being able to watch Youtube on my phone at last! Nice one!
Thank you all ever so much

id recommend you dive straight in and install cookies home tab(CHT) mod and CHT editor. (Link is in the CHT mod thread).
Not only do they make sense wonderfull, but it has built in quicklink assignable toggles for BT, wifi and such.

This is seriously wonderful! Thanks for the sharing this info and the link.
I've put the stuff on this evening and the add ons to get me the bluetooth toggle.
As the title states I need to know if Logcat can or will show me all recent behaviour and actions? Can it do it if the phone has been flashed back to stock?
I ask because I watched my partners phone going a bit erratic to say the least.
All sorts of things were being opened in front of us with no one touching the phone. Messages were being put to us on the screen, files were deleted, files altered.
Photo's were altered, favourites altered.
Had I not seen this with my own eyes then I would have found it hard to believe, but with personal details, bank details, photo's, addresses etc being on phone and looking compromised I would like to get to the bottom of this quickly and by any means possible.
As much as I know about ROM cards, Nagraedit etc this is a field I know nothing about although a friend told me that it's not normally done to this scale.
If Logcat can't help me could someone give me any suggestions as to how I may track the activity, cause, source etc?
All security apps that have been run find nothing! One app was classed as dodgy and was promptly deleted but there are still some things vanishing. By vanishing I mean we have a look then exit only to see they have been removed. Some time later they seem to be put back in. Some things marked as favourite are unchecked as we look at the screen yet we have touched nothing.
As crazy as it may sound it has happened and I want to eliminate all possibilities as this happened few days after flashing with ROM & kernel.
Failing this then the phone may be sent off for analysis of some sort or sold and replaced.
Thanks in advance and any help would be greatly appreciated.

Just to update the post, All photo's were deleted from the sd card as well as various other folders and all personal stuff has gone!
Yes there are options available to retrieve them and I have the programs to do but it still doesn't take away the fact the some thieving scrote thinks it's good to play games by installing sh*t on his ROM to hack into phones, then steal whatever they want!.
Feels like we have been burgled!
Three ROMS were flashed in the week leading up to this, therefore that narrows the possibilities.
That and the fact that that a similar thing happened and the person on the other end was showing content from this site.
One ROM already ruled out and behaviour of another is casting doubt due to behaviour of the smiling balloon which seemed to become an app that was being downloaded, then reappear making out it was a recycle bin.
Just hope the trail leads to the clown responsible and not a goose chase
Now, not all developers are crooked or loading their ROM'S with stuff but regardless of who makes it, who praises it, who loves it and swears by it, who kang'd it etc I would strongly urge people to upgrade or buy a phone instead of rooting, popping this ROM and or ROM in.

What I would do is to flash a full stock ROM via Odin. Not an ordinary one, but a 3 part one (you can access it through a link in my signature). We are talking about an i9100 right? Not an i9100M/G etc? That 3- part stock firmware will wipe the device as it flashes. Then, don't install any apps after you've flashed. If nothing happens, great, put all your apps back on and see what happens.
Also, what ROMs have you flashed recently? And where did you download them from? I'd easily be over 50 ROM flashes and have never encountered any issues such as that. So have many thousands of others here on XDA.
And, what on earth do you mean with this bit:

Hi, thanks for the reply.
I used ROM'S from here but think it would be wrong to name them at this point till I get more info. The Mrs has had one or two from other places she now tells me , but there was no inappropriate behaviour before or after these. And any steps I have taken to install for her, I have obtained from XDA. All were Jelly Bean based and either 4.2.2 or 4.3.
Yes it's I9100 although it's I9100P. The variant hasn't had any effect in my opinion and have always flashed to stock then went through the usual steps of erase, wipe, format, mount etc.
There was once some nonsense from another superuser app, well not so much the app but one of the components which started zipping up stuff etc. That was eradicated immediately, and was several weeks prior to this carry on starting. For the life of me I can't remember the name of it but know I had used it before with no trouble whatsoever so did find that odd to say the least..
She had mentioned it before but I thought yeah okay, had I not seen it with my own eyes I wouldn't have believed her to be honest.
The content that was being shown from here was like watching someone scanning over a sheet of paper with a handheld scanner, only watching it on the phone. Sorry - can't think of any other way to describe it and the phone was just going to various sections on XDA - all to do with Jelly Bean. The Mrs assumed it was the dev from this other super user app pointing her in the right direction for Jelly Bean etc.
I recognised some of the content as I had in fact read them myself and went to the same pages on comp to show her but was expecting this message will self destruct in 5 seconds to come on screen and Mission Impossible music to start.
The behaviour in the latter stages was outrageous and somewhat audacious, but that's another story.
Just wanna trace it and sort it out and in one sense it's a lesson learned for her lol cos my phone is running just sweet lol.
just got this, new phone. I've been reviewing all its features, but it's started acting strange. when I plug in to charge, it no longer responds. the only way I got it to power on is after I remove/re-insert battery. I realize different phones will have different functions/settings, but my last phone never had these type of issues. I'm just at a loss as to what's going on. I have another week to return this phone, if it won't operate properly. Any insights would be greatly appreciated. I have the unlocked/no carrier logo, International I9300 version. It's running Android 4.1.1, which is what came installed.

Hi I will save you alot of trouble here... Return the phone...Your phone should not be doing this especially a new one even if you can fix this it is something that is not normal and can spell trouble elsewhere with your phone.
I would recommend returning and getting another one
+1 return it and go for new one. Why to bother when return is an option.
hardware problem..just return it
turns off, won't power on, after/while charging

I've done a factory reset & it seems 2 b responding, as it should. I'm hoping it means that just an app, I'd installed, was causing the issue. If not, I've alerted the seller that I'd be returning/exchanging. Does this type of thing tend 2 happen, very often?
Update: OK, it's been over 12 hrs. since I did the factory reset. I've not done anything else, except enter my local settings. I've not logged in 2 any pre-installed apps, either. So far, it's still working fine. Now, should I assume this DID have something 2 do w/an app or what? I'm really trying 2 exhaust all possibilities b4 returning, as this can only be returned, if there IS something actually defective.
Please advise, again.
Thx,
Tereasa
No, only when the user corrupts the firmware/data.

There is no way to really understand what's going on without testing but that takes time and that is something you haven't got seeing as you need to return the phone within a week..
You could install one app at a time test then uninstall that app and move on to the next app to test but that is very time consuming depending on how many apps you had installed. (And it might not even be that what is causing the problem)
You could flash a new stock firmware and test but again that is time consuming plus you don't want to be doing that if you are returning the phone.
I can only tell you what I would do and that is to return it..The reason why I say that is because not having your phone respond when you plug into a charger would be a big issue for me especially on a new phone and like i said in my first post this could be signs of trouble elsewhere.
I would probably ask myself this question... maybe it was just a app or maybe it's something worse "can i take the risk" Phones cost alot of money and I think you should expect them to work without any problems when first purchased.

:good:Well, as it turns out, it must be a serious issue w/phone. I've still not logged in/installed any other apps & it's starting do it all, again. So, back it will go. As u said, it's expensive! I really appreciate ur assistance.
I've got insurance for my cell phone through my credit card. If it breaks, they'll send me $250 to buy a new one. And my RAZR Maxx is definitely messed up.
The problem is, the problems are intermittent. And for me to make a successful claim, I have to get a technician to look at the phone and write a letter saying it's broken. I had to go through this process a couple of years ago with a Motorola Atrix that was clearly, obviously broken. And the technicians are always like, "what? what do you mean? what good is a letter like that going to do?" No matter how many times I try to explain to them. It's like they think I'm trying to trap them.
Anyway, is there anything short of throwing the phone off the top of my house that I can do to my phone that makes it easy to show to a technician and have him verify there are issues with it? I'd like not to destroy the phone in case my claim is denied. There are other criteria other than just proving phone is broken. And if the claim is denied, I may need to use the phone for a few more months till I can afford to buy a new one.
The phone is rooted. So I can install whatever software that needs the phone to be rooted. And I have asked in the past, rooting the phone does not cancel my insurance. The case is basically the cell phone insurance department doesn't seem very technologically savvy and don't have a lot of clauses you see when cell phone company's are describing cell phone warranties. Then they have other clauses that you would never see in a cell phone warranty.
If you want to know what's wrong with my phone, like occasionally, nothing it can do will it lock onto the GPS satellites, and I'm stuck somewhere trying to navigate my way to some place.. Occasionally it'll pop up on my screen saying "HDMI cable detected" and orient my screen sideways like if the phone were in a dock. It does this even though there's clearly no HDMI cable connected and I have turned HDMI detection off in the settings. Plus, the phone is just god awful slow a lot of times. Trying to use Chrome on the phone, a lot of times it'll hang and eventually I'll get the message "Chrome is not reponding", then I have options like do you want to wait for it, or go ahead and kill it.

Have you tried returning the phone to bone stock with a stock recovery image and rsd lite? Be fore warned, you will lose root but, you can get it back. Afterwards it will be like a new phone(faster, a lot less buggy and force closes) unless it is truly a hardware issue. I have a motorola xoom that started having serious issues, I went through the whole process, and it was like a completely new tablet when was done, battery life I hadn't seen in over a year, very responsive, it was like I had just unboxed it from the store.
Truthfully the technicians probably DO think you are trying to trap them when you are talking about intermittent problems. Intermittent problems are hard to diagnose with anything unless you can tell them a specific action or pattern of actions that leads up to the problem. I am sure they get a lot of people all the time with "it doesn't work right" claims to try to get money for a new phone.
IMHO it would be worth the shot to see if it legitimately has a goofy problem, or can be easily fixed at home.

Yeah, thanks Draxin. I've tried restoring to a factory image. And it seems to work okay for a couple of days before small things start back up. A couple of months later, the phone is as flaky as it ever was. It could just be software, that is possible. But it's not like I can go in and fix the software myself or anything. And I think hanging around the internet, looking for tweaks and fixes any more than I already have is really an unreasonable request by the insurance company.
What you say about an easily repeatable pattern, that's what I was hoping to figure out by posting here.
But getting no responses, I think I'm just gonna start my claim and when it gets to the point of proving it's broken, I'm just gonna microwave the phone. Googling all over the Internet that's the only advice people seem to offer.
Basically as it is now, I'm gonna have to pay for a new phone and hope this clumsy phone insurance through my credit card company makes good on my claim. I know I meet the criteria because I've read the policy. It's just the hoops they put you through to prove you meet the criteria that I'm worried about.

Very true. It is funny/sad. Spend some time on a site like this and it seems like everybody knows these things. Talk to your friend or the typical consumer of smartphones and it is foreign to them. They feed into the advertising that the newest and greatest will solve all their problems, not realizing they are falling into the same viscous circle. They will actually disbelieve you, cause... well come on, the phone is two years old! "The guy at my carriers store is surprised my phone still works. Sure he got the job two months ago, won't be there five from now and has no idea what a OTG cable is, or a independently powered usb hub but, still he works there.. so he must know what he is talking about! I am sure it has nothing to do with commission of sales!" (that was facetious, by the way)
I am curious how many people have thought that their smartphone was dying or to old because a factory reset didn't work(not talking about you lavender, I don't know what you have done to fix your device( guess I am semi-hijacking your thread)).
Motorola(or any device manufacturer for that matter) isn't going to tell the typical user that a firmware reflash is required to get a couple more years out of their device when they can sell a user (that won't waste the time to Google)another device. Certainly won't advertise it right next to their latest and greatest device. Really how many people outside of the power users or gamers REQUIRE a quad core processor with 1500-1800 mhz, or 2-3 gb of RAM. When typically, it will end up the same way in a years time, depending on how much they use it.
Porn doesn't require those specs!!!

I have a A52 5g and a tab S7+ wifi, that are both remotely controled and monitored, and serve as gateway to my home network and basicaly every device connected to it. I noticed it at first and mew NOTHING related to this, didnt even know what open source was. Since then i have come to understand that, somehow, my phone seems to run a custom version of android, my guess is, built from AOSP and designed to disguise itself as oem samsung ui, but in background enables remote access and total takeover of every function. I have discovered, using total commander, that storage has been partitioned in 2 separate locations, and that one folder in there is called root system file, and filled with data/apk/installkits/etc.. this has me asking for help in 2 specific questions:
Am i holding a rooted device or is there another possibility that creates this situation? I was convinced its rooted untill i read here that root prevents from using samsung pass, secure folder etc.. and those seem to work on mine(or is it a version of those apps?) If its indeed rooted, will it wype everything if i flash it with the stock rom? And should i trust a small cell repair store to do that or learn how to do it myself?
2: i have bought 3 brand new phones since august, and made sure not to use my usual accounts, no use backups, not even set it up near my home wifi, and it almost instantly started self installing harmful software in background. I see no other way for it to link itself to be owned by me at initial setup, but for the sim card, new of course, but with my usual phone number and service transfered to it. Is that enough to make a breach and compromise a new device? If so, what would be different after fpashing the stock rom, if everything reinstalls itself? Do i need to change my number? Change cellular service provider even? I know its an unusual request but im a fast learner, i have compiled lots of technical info on specific apps, ip's, servers, build id numbers etc.. that i know would make more sense to anyone more qualified than me, and i am about ready to try and wype/flash the thing myself, i just would feel better with a little help since i have gone this far pretty much alone, since no service provider or manifacturer actualy feels like this is their problem to solve....
Here you can download firmware for your phone and flash with Odin, which you can also download at the bottom of the page, there are instructions on how to do it also.
Make sure to download correct firmware for exact device you have. There are few different A52 5G models.. SM-A526B, SM-A526U, SM-A5260, SM-A526U1, SM-A526W.
You will lose all data after flashing new firmware. After this your phone will be like brand new from Samsung..
If your device is rooted then that means your warranty is void and manufacturers and carriers are under no obligation to help you.
I'm trying to understand your situation but its so conflicting I don't know where to begin.
For example, you say your device runs a custom AOSP with a Samsung UI. Thats exactly how it actually works. Samsung take the AOSP, customise it with their own functionality, then overlay their own skin as the UI. Theres absolutely nothing unusual about that.
I'm conflicted as to whether your rooted or not. If the manufacturer or carrier has physically seen the device and won't repair it then that would suggest your definitely rooted. If you spoke to them virtually and told them your rooted then they will use it as an excuse whether you're truly rooted or not. The partitions you mention could be the internal storage and an sd card which can be seen non-rooted. I dont know what you mean when you mention a "root system file". Is it an actual folder called "root" or is the app you're using just telling you that you've reached the "root" of the filesystem? I can't quite work out what you mean. You also say Knox-powered apps still work which just adds to the confusion.
You stated you have had 3 new devices and they all self-installed harmful software. To get one device compromised is possible. To get three compromised means your either a high profile government target (which I doubt because they wouldn't be so sloppy as this) or your doing something to compromise your own devices such as continuously visiting dodgy websites.
Flashing will fix things but so would having a new device. The only common denominator is you so either you're doing something wrong or you truly are a government target in which case I wish you good luck!
First let me appologise for the long silence, i cut off most online activity for a while and just read your answers. To clarify, i have not solved my prolem yet. But ill try to explain better what you ask about my situation:
About de os version arobase40 got it right. I Asked google play help reps. And a stock samsung version of android would not trigger googles warning about running a custom version of android. So that point to a modified after-the-fact more than to the fact samsung has their propierary version installed.
About beeing rooted or not, ylwhat you are asking is what im not totaly certajn of, also. I know partition can happen without rooting, its seems to have created a "virtual sd card" since its named as such when sd card slot is actualy empty. About the root files folder, i cant say for sure, all i can say is that its holding a large amount of Gigs that dont get taken into account when looking at storage capacity and usage, and accessing that folder gives me a message that root files cant be access from this device. Does it mean my device had root acess privileges revoked to prevent viewing files that hide what is given control of the software remotely, so i dont find out or have the capacity to remove or alter those files?
What is absolutely sure is that if it is rooted, it wasnt done by me. As for the chance the devices were not factory brand new, 1 of them was not, got it opend box from amazon, a saudi arabia version, but my prkblems had started months before getting it, did not keep it more than 2 months, and all others before and since are 100% pure factory new, some directly from my cellular service provider, as financed device came with 2 year agreement of service,(actualy 2 of them i got this way) and the last one is my tab s7+ i got online directly from samsung canada website, on preorder, delivered on release day.
And lastly the fact i cant seem to shake those persistent leeches, is not from having reckless habbits online, but from having careless and uneducated habbits before that all started, usual older lazy dude stuff, like not changing my wifi password after a ruff breakup with bipolar psycho ex gf, or having only a few passwords reused on most my accounts. I have stopped doing those things long ago now that i know better, but i suspect that i could have been unaware something gettnng installed and staying dormant for a while, maybe? The ex had way more opportunities than needed to do something like this and is more than psycho enough to realy do it also. For having the skills to do it, lets say she has "assets" that can easily get her guys willing to help about that. It may also be coming from somwhere else, but as you say im not a super spy or a high ranking gov. Official. Im not even that interesting, and have absolutely no usable id for fraud or anything, my credit history would raise more red flags then there is in all china. So after so long struggling with this still very active, i cant even think of a rational reason to do so much effort into this, theres nothing to gain, i only can imagine that maybe a twisted mind seeking revege, or with a sick way of amusing themselves could see the point to all that, but i dont realy care. I only want to get rid of it.
As for the way it manages to be so much persistent, i can only see one option left i didnt remove from the process, and its through my phone number/account on the sim card, even a new sim on a new phone, still is linked to my cell service. I did initial setup with only that new sim card, accounts freshely created during setup, with no info or anythink linkable to my previous accounts, and even did it sitting outside, far from any building that could get me in range of a wifi network. And it still was no more effective at staying secure.
Thats why i did not yet try to flash a stock rom myself on my device, because it would, at best, become exactly like it was when brand new, and i know that this is not enough to keep it secure, and that means theres still something im missing in the whole picture.
