How to fix xperia Z3+ heating issue

I just bought a new z3+ . when I playing games the temperature touches 70c .please help me to fix over heating issue

What version of android do you have? If it is 5.0 use Xperia Companion and update it to Marshmallow (Android 6). The heat problem is less on this version

There is sadly no solution. However its a great phone if you dont play games or use hd-videos.

70° !!!! This is too much bro.. I always play some games or gta san in max settings
And maximum temperature is between 45° - 48°
did not reach 50° or more

Lucky you, my Xperia Z3+ got to a point where I could not use it longer than 10 minutes without the overheating message pop-up. I sent it in because the Customer Support operator said they'll be able to fix the overheating issue (doubt it).

and install kernel adiutor app and put big core(s)on 768 and little cores on 960 and gpu on 390 and done

I flash Nougat with flashtool and no problems. Its less heat than on marshmallow.

The phone is just 1 month old... we'll see what solution Sony came up with after I get the phone back.
I'll keep in mind the advice to flash the phone, thanks for the heads up and the links.

If you wish for your phone not to overheat and play on it at the same time. I'd suggest playing the game while submerging the phone under water :laugh::laugh:

Would try that, but sadly no seller not even Sony themselves here give warranty for water damage, despite the phone being promoted as water proof.
So if i was unlucky and some water did get in, i would be screwed.

You are already screwed. You should have read through the forums here on this piece of sh*t phone before you bought it. It has been out two years, now. I unfortunately bought it when it first came out, so eager to have the newest and best I bought it months before available in the US, international version "NO WARRANTY." I learned my lesson. Sony has all but turned their backs on this one. It's even hard to find any mention of it on Sony's website..

I would've been screwed but luck favored me, I sent my Z3+ back to seller for warranty due to the overheating and white spots on screen that appeared some time ago, the seller couldn't fix it nor could he replace it so he gave me my money back, a win in my book.
I used this to buy a new phone something recommended to me Xiaomi Redmi 4 pro, half the price of Z3+ but similar specs, so far way more satisfied with it the with Z3+.
Give the brand a check, it's Chinese but they're good.

Good for you to take your money back, but make no mistake, Sony are way superior than Xiaomi (2 previous mobiles where xiaomi!)

Probably if we're talking top performance, like Z5 or other, but when comparing to Z3+ my Xiaomi is better, Z3+ would get around 10k more points in antutu, but when the overheating kicks in that score drops drastically and it heavily affects games with lower FPS and longer load times, my Xiaomi is doesn't have that heating issue so it offers smooth albite slower performance, and i did the same mistake as you, like a kid i wanted a smartphone from the top shelf but not too expensive so i got Z3+, only after suffering it i learned what i needed from my android and a mid-range phone like Xiaomi Redmi 4 Pro suits me perfectly.
Plus the battery last nearly twice as long then the one in Z3+ even thou Z+3 has 1100amp less

I agree for the battery, ok. Antutu is pointless to compare. With xiaomi you have to set up, root, rom etc with bugs all the time that come up after 1 month usually, so you have to "refresh" it regularly - trust me you will have to deal with it. Sony has bugs too but not for all users and - usually - Sony fixes them. Anyway, i hope you enjoy your phone! I had iNewV3, Xiaomi Redmi Note 2 and 4 but i feel than with Sony i feel more confident!

Digitizer issue?

Hey guys, so I've just recently gotten a Note 5 (W8) for pretty cheap. At first, the lack of expandable memory was really hard to handle, because I'm used to backing up everything daily. However, I've come to like the phone, because I really missed Samsung and all it's awesome features.
I purchased the phone with the caveat that it didn't respond to touch, and I was pleasantly surprised when it arrived and I saw that only a small portion of the screen was affected. Basically from a little above the dock area and below. The home, back, and recent buttons aren't affected, and I'm able to use the S-Pen on the area that doesn't respond to touches.
Before I bought the phone, I read online that the issue may be related to a bad digitizer or maybe the touch software just needed to be updated through the dialer. Well, I've completed the touch update several times and the issue still persists, so now I'm at the point where I think that this might be hardware related and I just wanted to get some opinions and expertise from you guys.

I wish mine was like that, it's perfect except for that one issue. At first, I was going to attempt opening the phone and swapping out the digitizer, but after watching a few videos on the dismantle, I've decided I'm not brave enough for that. It's on the same level as opening up an S8 or a Note 8. I miss the days of the removable battery.

New at Xiaomi Phones...will buy a Mi9, so, im introducing myself, and ask some tips!

Hi guy's, so im new at Xiaomi devices for myself...yes, look strange to me that i have recomended all kind of Xiaomi devices to my family and myself didnt have one, so that is about to change.
Long story short, Xiaomi fan since 2016 and buying all kind of things (Powerbank's, selfie stick, mi band 1S and Mi Band 3, Mi Speakers and so on) but never going for a phone...all recomended by me then, my girfriend buy a Redmi Note 4 almost 2 years ago, my mom a Redmi 5 last year, my brother a Mi A2 last christmas, my father a Mi A1 in May, and my cousin a Redmi Note 7 in May too.
I see everyone happy with their phones so i will go for a step above and buy a Mi9 cause i only can live with a "higher spec" one - dont compare with expensive one, cause i never buy expensive ones (more than 500 euros).
Now, im here and a Mi 9 should arrive within 2 weeks, i only have one choise: 6Gb/128Gb cause, storage for me is a must and since this phone cant handle a microSD, i be sure that my 25Gb of FLAC audio need to go somewhere big and i need space for more and more, and videos and pictures.
The color is a black one, cause i want straight and simple, elegant but i need to admit i already touch and use a Mi9 at store in blue color and i love it so damn too but for me is all black. Why my choise about Mi 9? easy, im usually buying phones with IR blaster cause i need it, and love to have it (trolling mode, and my job at repair store is a easy for me).
In search for a need of a phone with wireless charging, is a no brainer to chose a Mi 9, i want to try out that on display fingerprint scanner and i already did, and fall in love too, is a quick and easy step in technology in general.
Overall, Mi9 have it all, all i need and want.
So my questions to Mi 9 users and to try improve my experience with my device are:
1 - what the best method to debloat the phone without unlocking the bootloader? - in my LG G6 have a cmd list and then debloat by using it, they are not deleted but is deativated in the phone so they wont run and save memory. - are something similar to do with Mi 9?
2 - for who use wireless charging: do the phone gets too hot that you are affraid of glass back to look like or you think it will break?
3 - right now, the stock rom have some "big deal" bugs?
4 - the back scratch easy? i mean, you do the first 2 or 3 cleans and they already have scratches?
5 - best glass screen protector? i see a lot of 3d, 4d or so new type of screen protectors but im afrraid because of the corners will not adhere fine or lift when the phone be inside a case. Nillkin someone? - i usually use that brand for my G6 and until now is perfect.
6 - for people who are in Global ROM, there still ads all over stock apps or is gone?
For now is everything, sorry for this long text but im hype right now, is a new toy coming and i need to threat them right.

As a Mi9 user, I only can answer 3 questions properly;
3.- Stock rom doesn't have any major bugs (Not that I have found) but they're updating it pretty slow.. we're a couple of versions behind other devices like the redmi ones.. Although, I always see flashing a xiaomi.eu rom as a "must do", because is debloated, has better ram optimization, many extra options, etc. But that's just preference.
4.- I don't see the back panel scratched till today, I've been using this phone since a couple of months, but I would recommend using a case just in case.
5.- I use hydrogel screen protectors on almost all my devices, you can search what are those if you want, but I recently found one from the brand "Jasinber" on Amazon, it feels premium and it's pretty cheap, includes all the usual installation kit and 2 pieces, it has a black border but doesn't "eat" that much from the screen tho.

thanks for your reply, as about the xiaomi.eu ROMs, you can flash it right away or need to unlock bootloader in order to flash them?

need to have bootloader unlocked to flash xiaomi.eu or ROS etc.
If you have the global version you can jump between the europe and global version ROMs with bootloader locked using XiaomiMiTool V2 but never to china rom

so, obvious i am gettin a Global version...i am reading with, with MiTools v2 you can flash .eu firmwares without unlocking bootloader?
if so, thanks...i will do it sure, only thing i dont want is unlock the bootloader for now, i will give time, 3, 4 months until i do that cause im affraid of the phone have some kind of issue and let me down with booloader unlocked and my guarantee is void after that.

Xiaomi ADB Fastboot tools is the easiest way to debloat IMHO, you can choose to disable/delete apps from a preconfigured list. https://github.com/Saki-EU/XiaomiADBFastbootTools
SirTAVARES considers a lot more things "bloat" but has a great list you can use with ADB to delete things

No, but I haven't got the 27W charger so it's not going that fast. It does get quite hot playing games while fast charging using a cable, but it's just uncomfortable, I'm not worried about it breaking
3
Was happy enough on stock, but there were a bunch of quirks that weren't quite "dealbreakers". I tried out xiaomi.eu and am much happier, it's pretty much stock but outright better. Not sure about the current state of stock, but notifications missing from the status bar was the worst.
4
Glass back does scratch, but not through just cleaning. I think I have faint key marks but it still looks amazing and you wouldn't notice.
5
Am using a Cafele that came free with their cheap case.
+ Has a front camera cutout
+ Has this edge solution that works great, and can be used to hide existing scratches
- Not 3D, doesn't feel as nice doing edge gestures
I read the drawback of some (all?) of the Nillkins was the camera hole gets dusty or if you misalign it it's in photos. Ones with cutouts are probably better

So, im learning and reading something around i have seen a lot of people complaining about audio latency on bluetooth headset and low volume problem, anyone can confirm is general or affect only few devices?
its software related and if it is, how to solve that?

Bluetooth hasn't been a problem for me in xiaomi.eu. (I use LDAC/APT-X codecs only though) Low volume is software, if you forget the device and repair it should get it's normal volume back. It only happened a couple of times for me.

1. you have a tool to debloat it via fastboot, a java app is available in this subforum, called Xiaomi ADB/Fastboot tools. You can manually select what to remove.
2. Phone doesn't get hot while fast charging, though I am using a 5w Samsung wireless charger.
3. No major issues in the stock rom, other than the fact that the notifications only briefly show on the bar. Easy to solve without root by installing NotchTest from the playstore.
4. Have no scratches on the back and I also don't use any phone cases most of the time.
5. I bought this case because it looks typical spygen and only have good things to say about it.
6. I've never seen an ad on this phone.
By far the best phone I ever used. Super fast and smooth, incredible camera, MIUI is not really bloated imo, overall a great experience.

[Fixed] Touchscreen and scrolling issue S20 FE 5G

Hello there (General Kenobi)
Just got my brand new Galaxy S20 FE 5G a few days ago but I'm experiencing the touch screen issue. My phone is up to date but I still have the problem. When I have to scroll, the screen doesn't respond at all or thinks it's a tap on the screen and it suddenly goes crazy.
It does only occur on the bottom part of the screen after I unlock my phone from a long period of non use.
I contacted Samsung and they told me to get it to a repair center. But I don't know if this will work and I'm a bit scared that getting it to the center would make things worse.
I saw that Samsung already rolled 3 updates out to fix this problem but I'm still not sure if it is a hardware or a software problem.
Did you guys face this issue? Do you think it is a hardware problem and I should repair it?
It is a good phone and after having left the Pixels because of hardware problem I'm annoyed

*WELL hello there
I get the occasional unwanted zoom in a browser or failure to respond to touch, what you're describing sounds worse than the multitouch issue others have been reporting.
I'd give serious consideration to returning that phone for a replacement or refund. the current reckoning around here seems to be that this phone got a digitizer from a cheaper price range compared to other S20s. what you describe sounds like a faulty digitizer.
is putting up with it for a couple of years not going to bug the crap out of you ?
if they offer only to repair it, accept only a new screen / digitizer / glass swap out.

About the famous multi-touch problem I have to admit that I tried to reproduce it but it only appeared when I was using 5 fingers (instead of 2 in the videos I saw)
I think you're right and I should get it repaired. And I'll see after that if the problem is still here I'll ask for a replacement. I will post an update as soon as I get it back
Thank you!

If you don't mind, could you let us know your phone's hardware revision number? An app called Phone Info *SAM* can show it. People would be interested to know if Samsung has made any hardware changes to the FE line.

Okay guys I'm sorry I couldn't reply before. I had to sent my phone for a repair THREE TIMES ! The first time they didn't do anything but damaged the back of my phone (replacing the screen and the battery) and the problem was still here. The second time they sent my phone back with the battery literally filled (the back of the phone was also damaged due to the battery that had filled).
I got my phone back on last Friday. Seems to be OK. They told me they couldn't reproduce the problem. They just repaired what they did wrong but didn't seem to do anything with the touchscreen.
The phone looks OK. After 1 day of use, the touchscreen seems to be OK but I would like to wait a bit before adding [FIXED] to the title of the topic

Does anyone know if the 2021 version of FE the 4G Snapdragon (g780g I think) has the same problems with ghost touches and jittery scrolling? Can't find info on that anywhere. Deciding between the FE and 8T, but the risk of bad touchscreen is driving me away from it although it's better phone.

I'm sorry I couldn't tell you. I bought my phone around February and it has the problem. This is the 5G variant with Snapdragon 865. I didn't even know there was a 4G variant with Snapdragon (in France, it's either 4G/Exynos or 5G/Snapdragon).
The phone is great though and now my problem seems to be fixed I'm keeping my S20FE over the Pixel 5 even though I'm a Pixel fan.

actually it looks like that's the only issue he didn't have.

That all sounds like an Exynoss version He might be wrong, maybe it is Exy?

Haha I don't feel concerned about the problems that he had because coming from a Pixel 5 some of the problems he had was worse on the P5 (reception, sound quality and the fact that the device can get warm)

Question Mi 11 Wifi Stopped Working

why though, I've had it for quite some time now and I went to sleep one day and today it was like that with no reason whatsoever. I'll go to the service center ASAP. You think they can just fix the broken part or do they have to change multiple components or something?

If it's still in warranty you'll get a new phone otherwise board would be replaced....sadly this always how it happens either when you restart it or the other morning I really hope mine doesn't happen it's related to device being consistently overheated

Make sure you take action quick as wifi failure is a precursor to the main motherboard getting fried.
Source: personal experience. Just had my Mi 11 motherboard replaced under warranty. Luckily only lost one week's worth of data as I did a backup prior to the whole phone going kaput.

The issue seems to be more complex than what meets the eye. Qca6490 is both the wifi and Bluetooth 5.0 chipset, having it break would mean making both of them nonfunctional but we know that's not the case for Bluetooth.
I have a theory about what the issue is but I don't have enough data to confirm it. It would help me if you could download Device Info HW from PlayStore and get screenshot of SOC, SYSTEM and THERMAL tab(of the latter it would be better if the device was cooled down, data disabled. I would just need screens of modem-wifi-usr, the four voices starting with pm, wireless-therm, wifi-therm)

Are these taken when the phone was cooled down and data was either turned off or turned on by no more than a few seconds? In any case I would need the temps of pm8350, all the three voices and pm735, scroll down and you can find them easily

heh funny, exactly same thing happened to me two days go and not even on miui 13, i try to hard reset and update phone to miui 13 to see if its software issue but nope, so i have give phone to service under warranty second time, first time was display, really dissapointed with those issue on one year old flagship model

This is only based on a very small sample of devices analyzed and it may be not accurate. If people with this issue see this, I hope they can try to reach me out so we can get more device samples.
Okay, so this is what I found:
1. The Mi 11 that had their wifi fried under the system tab they all expose the Bluetooth voice. This is actually very odd because not all of them do which may indicates differenent revisions in either the wifi/bluetooth chip, motherboard or the SoC itself. I am not saying that all the ones that expose the Bluetooth voice will fry but, as it stands now, all the ones who had their wifi fried they all exposed the Bluetooth voice.
2. They are characterized by extremely high temperatures that not only interest the SoC but seems to be spread throughout the entire motherboard. What strikes me as extremely suspicious is the pm8350 temps aka the PMIC. They were quite high in all the samples with broken wifis. While this could be attributed to the fact the pm8350 chipsets are just behind the 888 which is known to be a hot SoC, I would like to focus on a particular data. We have seen similiar high PMIC+SoC combo temps in other devices such as the Poco X3 Pro which is known to have faulty PMIC issues that can cause hard bricks. It wouldn't surprise me if this was also the case, after all the PMIC is tasked with DVFS and a faulty one may not be scaling frequencies and voltages properly. That may be the cause of the unexplainable, increased heat that may damage a component or a series of electronical components around the wifi chipset itself.
3. All the devices that had their wifi fried seems to have broken before or around their first year of use. Again this is only based on a way too low sample of devices but as it stands now the chances of it breaking after the first year of use are very low. This particular detail made me think that there may have been a particular wifi firmware bug that triggers after a specific date, a sort of time bomb which isn't unheard of in softwares. Even though I am pretty positive this is not the case, trying to set your phone time to a day previous to the one where your wifi broke won't hurt just to check.

1- I am not sure I understand what you mean by bluetooth voice.
2- While am not a techie in this particular field and don't fully understand the scope of this point, I'd like to offer an uninformed opinion nonetheless based on my academic background.
Could it be that the heat that is spread throughout the motherboard has to do with a defective vapor chamber? It is a well-known fact that SD888 is a behemoth when it comes to its heat output, most companies address this by adding a vapor chamber in their phones to dissipate the heat and if I remember anything from my heat transfer classes, it stands to reason that a defective VC would lead to heat not dissipating properly, leading to the entire motherboard having issues and maybe the Wi-fi module is the weakest link in this chain?
However, this does not explain why the SD888 itself doesn't fry, maybe it has to do with its built in throttling mechanisms? I don't really game on my phone and the most I do is Spotify and maybe Netflix so I never really pushed it to test if i'd fry the SD888
3- The software bomb is an interesting but imo a very unlikely theory considering the heat signature output its most likely a physical hardware issue. I unfortunately cannot test the hypothesis as I handed in my phone to the MI service center today They said they'll let me know in a week so I'll keep y'all updated.
Lastly, I would like to add that this is my first flagship phone, I normally used midrange smartphones but this time I thought I'd get something stronger and to be fair I kind of regret going for this phone specifically because of this issue.
The device itself looks great, runs smoothly, has a fantastic display and the fast charging is out of this world, the fact that I got a free 80W wireless charger too makes it even more spectacular, it is a good phone.
However, this does not excuse the fact that it broke down less than a year from my buying it (I got it last August) and a good phone is as good as the experience it provides and recently, the MIUI 13 barebone update put a bitter taste in my mouth considering how incomplete it is, coupled with this catastrophic hardware failure, I cannot in good conscience recommend that anybody goes for a flagship phone from Xiaomi anytime soon.
Had this been a singular individual error, I could have chalked it down to a manufacturing issue with my particular unit which is excusable, but ever since I posted, I've done some research and a LOT of people have had this issue which means its negligence on Xiaomi's part to conduct a proper QC/QA testing before rolling out their devices and such laziness cannot be excused. Here's hoping I'll get my unit back soon

Had the same exact issue last week.. Wifi has been working fine for a year, and then all of a sudden it won't turn on.. Sent it to repair.. Hopefully I get a new device.

Okay, so I got my device back today, they had to change the entire board, the Wi-Fi is now functioning again. It is unfortunate that it broke down in the first place but at least they fixed it rather quickly. Hopefully it wont break down again in a few months time @[email protected]

Let's hope so but I would say that if when it is in idle, cooled and with only wifi turned on and the temps aren't above 34/35C then it should be fine

after install the last stable version of xiaomi.eu rom(xiaomi.eu_multi_MI11_V13.0.8.0.SKBCNXM) on my mi 11, Wi-Fi stoped to work after a day and Bluetooth and 4g/5g not working proprielly anymore. I reed about the hight heat of sd888 burning the Wi-Fi modem of mi 11 in Internet. Anyaway, I already buy another smartphone...

@hhwjthje , a new owner here. Would you please clarify what you meant by bluetooth voice. Couldn't find that on @M.Walaa screenshot and we know he had the fried module. I also don't seem to have a position for bluetooth voice.
Also not sure why you think idle temps matter, when it's clear prolonged load temps is what's causing the damage.

Had the same issue. Suddenly the WiFi stopped working after around 10 months of use. I am from Bangladesh and no-one can possibly fix this issue in here. Contacted the seller and they asked me to wait until Chinese borders fully opens. They will send the unit to China. I have been a big Xiaomi fan but the experience I am having with Mi11 is disastrous.
