What is true of this model and changes how you fix it
- Camera — 10MP front, 3 rear12MP Ultra Wide, 50MP Wide, 10MP Telephoto (3x optical zoom) — identical camera hardware to the base S22.
- Display and battery6.6-inch screen, 4,500mAh battery. No built-in S Pen (Ultra only).
- Storage/RAM128GB or 256GB, 8GB RAM.
- Update windowAn older flagship — still supported, but nearing the end of its major-update window; a missing newest feature can be a support-age limit, not a fault.
- What owners run intoThe first-generation chips are known for heat and fast drain under load, and after several years the battery is also worn, so complaints about hot charging, short life and throttling in games are frequent. The phone is at the end of Samsung's update promise.
- How to approach a faultAvoid charging in a case or in the sun, lower screen brightness, and close heavy apps. If it still overheats at idle, boot into Safe mode to look for a rogue app.
- Finding your chipSettings, About phone shows the model number; SM-S906U is the Snapdragon model sold in the United States, and SM-S906B is the Exynos 2200 model sold elsewhere. Forum advice about throttling and heat differs between them.
- Dealing with heatHeavy gaming, 5G in a weak signal area and charging in a case all warm the S22+. Lower the screen brightness, switch to 4G in a poor 5G area and take the phone out of its case while charging if it becomes hot.
- Update window and next stepsSamsung's promised updates for the S22 line have ended, so security patches now matter more than features. If your patch is old, consider a battery replacement and a clean install to extend its life, or plan an upgrade.

Exact questions
Questions that only have an answer for the Samsung Galaxy S22+
My Galaxy S22+ stopped getting big Android updates.+
The S22 series has a defined support window (several years of OS upgrades and additional security updates), so an older model eventually stops receiving major new Android versions while still getting security patches for a while. A missing newest feature is that support age, not a fault. Check Settings › Software update; if no update appears, your device has reached the end of its major-update period.
Why does my S22+ get so hot?+
Its first-generation chip runs warm, and an old battery adds to it.
Is the S22+ still updated?+
It is at the end of its update window.
How do I tell which S22+ chip I have?+
The model number ends in B for the Exynos version.
Why switch to 4G in a weak 5G area?+
The radio works harder on a weak 5G signal and drains the battery.
