r/Pixel4a

Hi everyone.

I have a Google Pixel 4a 5G and recently it started acting very strangely.

Main problems:

Random freezes and reboots

Once it suddenly played a loud siren/SOS-like sound by itself and rebooted

Sometimes the whole phone becomes extremely laggy while watching YouTube

The video itself can continue playing smoothly, but the UI/system lags heavily

Occasionally the phone freezes completely and reboots

I also received overheating warnings while recording 4K60 video, even though the phone only felt slightly warm

Some extra details:

The issue happens mostly during YouTube/video playback

Some videos work fine, some cause lags If I pause the video, the phone becomes smooth again

In Safe Mode the problem still happened

I tried disabling HW overlays in Developer Options, but it did not really help

I already generated a bugreport

No obvious battery swelling or severe external overheating

Android version: UP1A.231105.001.B2

I’m trying to understand whether this is:

a motherboard issue,

failing storage/RAM,

GPU/video decoder issue,

thermal problem,

or some Android/software corruption.

Has anyone experienced something similar on the Pixel 4a 5G?

Also:

Is a factory reset worth trying at this point?

Could this be caused by hardware degradation?

Is there anything important I should back up immediately before the phone potentially dies completely?

Any help would be appreciated.

My first pixel was a pixel 4a. Well it made me fall in love with pixel. So when it came time to upgrade, I upgraded to pixel 7 since it was the newest at the time. Bad decision. I got a hold of a bad pixel 7. Man its so bad I went back to my pixel 4a and that's what I'm using now till I get the money for a pixel 10. Hopefully it won't be a bad phone!!

Pixel 4a sitting unused for 2 years — how do I turn it on without getting hit by the battery-killing January 2025 update?

So I have a Pixel 4a that's been switched off for about 2 years. Just found out about the infamous January 2025 Android 13 update that apparently destroys battery performance on certain devices.

Has anyone dealt with this? What's the safest way to turn the phone back on without getting the update installed? Any help appreciated!

I checked my pixel 4a this morning and the section that said 'This device has unlimited backup' in Google photos is gone.

I used to have a Google One subscription that came with my P9PXL, that I didn't renew after a year on the 3rd of May. Is this just a visual issue or should I be worried?
