How to Stop Spam Texts on Android: 8 Free Fixes (2026)

Last updated: November 9, 2026. By Veer. Checked against Google Messages Help, Pixel Phone Help, the Google Keyword blog, Samsung US support, the FTC, the FCC, Ofcom, GOV.UK, T-Mobile, Verizon and AT&T. This is a researched how-to guide built from official documentation; we haven’t run our own spam-filtering experiment.

“Your package is on hold.” “Unpaid toll, pay within 24 hours.” “Hi, is this Sarah?” If your Android phone gets texts like these every day, you’re not alone, and most of the fix is already built into the phone. Android doesn’t have one single “block unknown senders” switch like the iPhone’s Screen Unknown Senders. Instead it leans on Google Messages, which filters spam on the device, warns you about likely scams and lets you report a number in two taps. Here’s how to use all of it, plus the free carrier tools that stop spam before it reaches you.

How do I stop spam texts on my Android phone?

Make Google Messages your texting app, keep its spam and scam protection on, and report and block whatever still gets through. Google says spam protection is on in standard mode by default, and that messages it detects as spam or scams “can be dropped and senders can be suspended” (Google Messages Help).

Here are the eight fixes, in the order we’d do them:

Should Galaxy owners switch to Google Messages?

Yes in the US, where Samsung Messages has been discontinued; in the UK it’s optional but gives you the newer scam tools. Samsung’s own Samsung Messages page says the app “has been discontinued,” that the change applies “to the US Market Only,” and that the app stopped being downloadable from the Galaxy Store in July 2026. Samsung also says Galaxy S26 owners can’t download Samsung Messages at all, and that sending texts from it is no longer possible after the shutdown except to emergency numbers.

To switch, open (or install) Google Messages, tap Set default SMS app, choose Google Messages and tap Set as default. Samsung says your existing conversations move over automatically, and that a full transfer can take up to about 24 hours.

If you’re in the UK and still use Samsung Messages, you can block a sender by touching and holding the conversation, tapping More, then Block, according to Samsung support. Its blocked list lives under Settings > Block numbers and spam.

How do I turn on spam protection in Google Messages?

Tap your profile picture, then Messages settings > Protection & Safety > Spam and scam protection, and choose Standard or Enhanced protection. The three choices, per Google Messages Help, are Enhanced protection, Standard protection and No protection.

1. Open Google Messages.
2. Tap your profile picture or initials at the top right.
3. Tap Messages settings > Protection & Safety > Spam and scam protection.
4. Pick Enhanced protection if you see it, or leave it on Standard protection.

Standard protection works with your message data on the phone itself. Enhanced protection can also send message data to Google’s Private AI Compute, which Google describes as a “secure dedicated space” where the data is encrypted and not available to anyone else, Google included.

What is Enhanced protection, and should I turn it on?

It’s a new opt-in mode, announced on October 14, 2026, that adds cloud AI scam checks for chats with unknown senders and stricter link warnings. In its announcement, Google said Enhanced protection uses “cloud Gemini models to evaluate complex message context” in conversations with people not in your contacts. It also uses on-device Gemini Nano to judge whether an unfamiliar link is trustworthy before you tap, and shows a clearer warning before you open links from numbers not saved in your contacts.

Google said the rollout would take “the coming weeks,” so the option may not be on your phone yet. 9to5Google reported on October 23 that the smarter link checks were limited to the Pixel 10 and later, the Galaxy S26 series, Z Flip 8, Z Fold 8 and “other select devices.” If you get a lot of “wrong number” texts that turn into investment or romance pitches, it’s worth switching on. Those slow conversations are what Google built it for.

Google says its Scam Detection already flags “more than 5 million suspected scam calls and texts every month” across Phone by Google and Google Messages.

How do I block and report spam texts on Android?

In Google Messages, touch and hold the conversation, then tap Block, then Report spam, then OK. According to Google Messages Help, reporting a conversation as spam also blocks the sender and moves the thread to your Spam & blocked folder.

• From inside a chat: tap More options > Details > Block & report spam > OK.
• What gets shared: Google says a report sends the spammer’s number and up to their last 10 incoming messages to Google. Your past replies aren’t included, and “the spammer can’t view your report.”
• Your carrier gets a copy too: Google says a report may create a “Spam reporting” conversation that sends the number and the latest text to your mobile carrier.
• Changed your mind? Open Spam & blocked from your profile menu, select the contact and tap Unblock (Google).

You don’t have to report to block. Plain Block works for a sender you simply don’t want to hear from, like an ex-colleague or a shop you can’t unsubscribe from.

Does forwarding spam texts to 7726 work on Android?

Yes. 7726 spells SPAM on a keypad, and forwarding to it is free in the US and the UK. In Google Messages, touch and hold the spam message, open the menu and choose Forward, then send it to 7726. Your carrier may reply asking for the number the text came from.

• US: The FTC says forwarding to 7726 “helps your wireless provider spot and block similar messages in the future.” You can also file a report at ReportFraud.ftc.gov.
• UK: GOV.UK says to forward suspicious texts to 7726 and that “it’s free.” Ofcom recommends reporting in your messaging app and to 7726 so both the app provider and your phone company can act.

Don’t reply STOP to a number you don’t recognize. Ofcom warns that replying, even to opt out, tells scammers your number is live, and Verizon gives the same advice. Save STOP for brands you actually signed up with.

How do I block a number that keeps texting me?

Block it in Google Messages, and on a Galaxy also add it in the Phone app so calls are stopped too. On Samsung phones, Samsung support says you can open Phone > More options > Settings > Block numbers and type the number in. The same screen has a Block calls from unknown numbers switch, though that only covers calls, not texts.

Blocking works best for one persistent sender. Bulk spammers rotate through thousands of numbers, which is why the filter and reporting steps above matter more than a long block list.

What is Scam Detection on Pixel phones?

It’s an on-by-default Pixel feature that warns you about likely scam messages from popular chat apps, not just texts. Pixel Phone Help says suspicious notifications get a red warning icon and a “Likely scam” button, and that the feature is available in the US, UK and several other countries. You’ll find the switch under Settings > Security and privacy > More security and privacy > Scam Detection.

Google says marking a message “Not a scam” turns detection off for that conversation for a while, so only do it when you’re sure. In October, Google said it was bringing these chat scam alerts to phones from Honor, Motorola, Oppo, OnePlus, Xiaomi and other makers, as The Verge reported.

Does my carrier block spam texts for free?

Yes. The big three US carriers and UK networks all filter some spam at the network level at no extra cost.

The FTC also points to CTIA’s list of carrier and call-blocking apps if you want a third-party filter. Many charge a subscription, and the free Google and carrier tools are enough for most people.

Why am I suddenly getting so many spam texts?

Usually because your number turned up in a data breach, a data broker listing or a sign-up form that shared it. The FCC advises being careful about where you give out your mobile number and checking privacy policies for opt-outs first.

If the flood started after a breach notice, our guide to removing your personal information from the internet for free covers the data broker opt-outs. If texts are asking for login codes, read is SMS 2FA safe? And if you also own an iPhone, the iPhone version of this guide covers Apple’s filters.

What if I already tapped a link in a spam text?

Stop, don’t type anything else, and change the password of any account you entered. Verizon says a suspicious text “typically will not put you at risk if you do not reply, click on links, or share any personal information.” If you did share card details, call your bank. If you installed something the text pointed you to, read how to tell if your phone is hacked, and use our checklist on checking if a website is legit next time a link looks off. Keeping Android patched helps too; see the November 2026 Android security update.

Verdict

On Android, the biggest single fix is making sure Google Messages’ spam and scam protection is on, and choosing Enhanced protection once it reaches your phone. After that, Block > Report spam and forwarding to 7726 do the heavy lifting, because they feed both Google’s filters and your carrier’s. US Galaxy owners should finish the move to Google Messages now that Samsung Messages is discontinued there. Paid filter apps are optional for most people.

FAQ

How do I stop spam texts on Android for free?

Use Google Messages, open Messages settings > Protection & Safety > Spam and scam protection and keep Standard or Enhanced protection on. Then block and report spam texts, forward them to 7726 and turn on your carrier’s free spam filtering.

Is spam protection on by default in Google Messages?

Yes. Google says spam protection is on in Standard protection mode by default. Enhanced protection is an opt-in mode that Google began rolling out after announcing it on October 14, 2026.

Can I block all unknown numbers from texting me on Android?

Not with one switch. Google Messages filters suspected spam and runs scam checks on chats with non-contacts, but it doesn’t have a setting that silences every unknown sender. Samsung’s “Block calls from unknown numbers” setting covers calls only.

Does reporting spam in Google Messages tell the sender?

No. Google says the spammer can’t view your report and won’t know about it. The report sends the sender’s number and their recent messages to Google, and may send a copy to your carrier.

Is Samsung Messages being discontinued?

Yes, in the US. Samsung says Samsung Messages has been discontinued in the US market, stopped being downloadable from the Galaxy Store in July 2026, and recommends switching to Google Messages. Phones on Android 11 or lower are not affected.

Should I reply STOP to spam texts?

No, not to unknown senders. Ofcom and Verizon both say replying confirms your number is active. Only reply STOP to companies you knowingly signed up with.
