Screen is stuttering everywhere. - Xiaomi Mi 4i

Hi. I have a problem with my borther's Mi4i. Everything worked fine till yesterday. His phone started lagging, at least he thought that it was a lag.
I looked into it and unfortunately it lags even in recovery and fastboot. I tried playing videos but sound is working OK. It looks like broken screen (like ~2-3 fps), but ... how? And my main question, how to repair it?

TF speakers issue

Hi guys,
It seems I have a big problem with my TF. I updated to 3.2 several days ago, everything running smooth and OK, but this evening while I was watching a movie, sound went dead on the right speaker and the left one followed pretty soon. I tried rebooting the device and playing a song and I'd get sound out for about 1-2 secs and then it dies. After another reboot same problem, 1-2 secs I have sound then all dead. I wiped the device and tried a fresh install and guess what, I have sound for 4-5 secs and then it dies again. Very very uncool ...
I bought the device from Amazon.uk, do any of you guys know how they deal with things like this? This is the first gadget I've bought from Amazon.uk so I don't really know yet.
Had it since June, very happy with the way it performs and anxiously waiting for the TF2 but this really bursts my bubble .
Regards,
Try and flash the voodoo speaker fix, you can find it somewhere in the dev section. It's a software error with honeycomb.
Hey, thanks for the post, but I don't think its a software issue. First of all, it worked OK until now, and it worked for more than a week on 3.2, second of all if I shake it or tap on the backside, near the right speaker, it seems to work, at least for a couple of seconds, so it's hardware related

CS918 temporary blackout issue

I have had a CS918 box for around 4 months and it largely works very well, however every now and then (once an hour maybe, sometimes two or three times in the space of a minute though) the screen goes blank for a second or so, the sound also cuts out for this period of time also.
I was using stock firmware, recently updated to a 1080p kernel and custom rom, but this still persists.
I've changed the HDMI cable and the slot it's in also.
I'm leaning towards a dodgy power supply - has anyone else had this issue?
Many thanks

I've just bought one of these boxes and am having this issue. I've tried searching everywhere for other people having this problem and this is the only post I've found.
Has a fix ever been discovered?

I also have an issue with mine, and the answer seems interesting and related.
With mine the image flickers sometimes, and needs to be reset, other times the audio will just go quite for 2-3 seconds.
It very well could be a power supply issue, as it seems to be slightly loose, but the interesting thing is that the video keeps playing perfectly when the sound goes out.
It does the sound thing much more often now that it did before too.
got the same audio issue ... could it be the hdmi cable?
I have the cs918+ and have the same blackout issue I update the firmware frequently but still happens...

[Q] Screen lag

I've noticed a lot of people complaining about screen lag recently, where everythings just dull and slow (not so much touch issues)- and unfortunately im one off them people!
My phone is the newer branch (november) and im starting to have a slow screen ever since oxygen! i've gone stock 11s n its seem to followed me!
but i really think its heat related, it will be fine for the most part, once it starts getting warm (recently its been getting hotter then normal) the screen goes dull.
THIS IS NOT GHOST TOUCH.
my screen doesnt press random things, the phone is just dull to type on and stuff but only when its hot/warm, and when i say hot, i mean hot..
but im not doing anything different to what i used to and it used to be okay, but then again........weathers getting hotter....
my nexus 4 was horrible when warm also......
currently on cm12 nightly, 06.04.15
tried stock 11s too but only lasted a few hours
If anybodys noticed this PLEASE say something, also if this issue is because my phone is 'defective', will i be able to send it to oneplus for a repair? wil it be worth it? will it be free? how long will it take (*roughly*)
sorry for all the questions and blabber, it's just i've been wondering A LOT and ive not been getting straight answers.
Ps. NEVER had issues BEFORE oxygen. oxygen was NOT on my phone for longer than a day due to the horrible keyboard issues, but the phone was really hot during oxygen......... thanks anyway, :good:
I have the same problem. It seems to happen when my phone has been warm-hot for 15-20 minutes. No ghost touches, but scrolling is really laggy, and sometimes it doesn't register a tap on a link or app. It seems to go away if I let my phone cool down. I've looked everywhere online, and I've seen a few people mention similar problems, but most of the time it's about the ghost touch thing. I really hope it's not a hardware issue. I can't go without a phone for a month and a half for the RMA. People seem to have a lot of issues with RMAs. I'm surprised there aren't more people having this issue.
Also, I'm not on oxygen. I'm having the issue on Euphoria 5.0.2.
I started having the exact same issue two weeks ago, and I did not even try oxygen os. I also bought the phone in november. I tried opening the phone and cleaning the connector but it didn't help at all... now I'm having the issue all the time, not only when the phone is hot and it feels like I have a $30 phone
I really don't know what to do since I opened the phone,so no RMA possible. I bought a Moto E and I'm gonna have to use it until I fix the issue. I dont even know if it's software or hardware, that's a really strange issue.
Edit : the touch screen just worked fine for 2 minutes, then became laggy again

All videos on Oneplus 6 are broken after stock flash

So I installed pix3fy on my Oneplus 6 a while ago. It worked fine, but I realized if I ever Uninstalled it I would brick my phone, so that's what happened. I got it out of the way so I wouldn't have to deal with it at an inconvenient time. Anyway, after I've slashed stokc firmware, it seems some sort of video module on my phone is broken. Whether it's an mp4, YouTube, twitch etc. It has no sound as is extremely choppy. This even carries over to Spotify. Is something on my phone corrupted? How do I fix this?

Some got it fixed by flash-all.bat
Or used msm download tool.
Some others had motherboard problems and got it replaced ?*

Question Phone sluggish / videos do not play after a full charge

I have noticed this happening for the past two to three days now, where after charging my phone to 100% and taking it off the charger, the phone feels sluggish overall in some apps and any videos - be it local on device videos shot from my camera, videos that I have received via WhatsApp, Instagram videos and reels or YouTube videos and shorts do not play at all. I just see the video buffering or loading (the circle keeps going round). Only thing to fix this is a restart. I am not sure what is causing this behaviour but it is very strange and ridiculous. I bought the Pixel thinking pure Android from Google would be the best UX but this sucks tbh.
Anyone else facing a similar issue and any tips on what the reason could be? I have been trying to get in touch with Google support but could not get through to them today, will try again tomorrow.
Edit: it is now happening randomly throughout the day and the camera app is almost frozen during such an episode if I try to use it.
Can you use something like geekbench app to profile the phone when it's at like 20 % after a restart vs 100% no restart?

Here are the screenshots of Geekbench scores. Today's scores are from when the phone was exhibiting this strange behavior of videos not playing.
Unfortunately, this has started happening randomly through the day (and not necessarily after a full charge). I have seen that even the camera just freezes or is non responsive during such an episode. So I guess it is some sort of video driver issue?
I restarted the phone in safe mode and checked but don't see this issue happening in that mode. I've uninstalled apps that I've installed over the past few days. Still not sure what's the issue.
I checked with Google support yesterday and they told me to check in safe mode (done) or else perform a factory reset. Not sure if paying 1000€ for a phone only to factory reset it within a month for a wired issue seems justified. I have the same apps on my 6 year old One plus 3 and face no problems whatsoever apart from the phone being slow.

Hey, I don't mean to be a stickler here or tell you what kind of experience to have.
As a guy who deals with a lot of tech issues, I would recommend a Factory Reset along with google.
Things happen, and not EVERY device is perfect, try not to be done with the phone over resetting. I know it can be a pain but all devices need it from time to time. I work in IT and you would not believe the number of times resetting fixed an issue.
The time for concern is when that does not fix the issue or you are having to do it across multiple patches of a phone.
TLDR; ELECTRONICS BE WEIRD
