Contact Samsung Support directly for hardware problems

If your Samsung phone won't power on, your first contact should be Samsung's support team. They can walk you through basic troubleshooting over the phone or chat, and if the phone needs repair, they'll tell you whether it's still under warranty and what your options cost.

Call Samsung Support at 1-800-726-7864 (in the US). Have your phone's model number and serial number ready — you'll find these in Settings > About Phone, or on the back of the device if it won't turn on. If you can't access the settings, the serial number is printed on the box your phone came in.

Samsung also offers chat support through their website at samsung.com/us/support. This route is useful if you prefer written communication or want to keep a record of what they told you. Chat support can typically connect you within a few minutes during business hours.

Key Takeaways

  • Samsung Support at 1-800-726-7864 is the official channel for hardware problems and can tell you immediately whether your phone is under warranty.
  • Have your phone's model number and serial number before you call, as support will need these to look up your device history.
  • If your phone is out of warranty, Samsung will quote you a repair price; authorized repair shops often cost less for the same work.
  • Your carrier (Verizon, AT&T, T-Mobile, etc.) can also help if you bought the phone through them, though they typically refer you back to Samsung for hardware issues.
  • If the phone is old enough that parts are hard to find, repair may cost more than replacing it, and Samsung support will tell you that upfront.

Check your warranty status before paying for repairs

Samsung phones typically come with a one-year limited warranty that covers hardware defects but not physical damage or liquid damage. When you call Samsung Support, they'll pull up your warranty status using your serial number and tell you whether the repair is covered.

If your phone is still under warranty and the problem is a defect (not something you caused), Samsung will repair or replace it at no cost. If the warranty has expired, they'll give you a price quote. For many phones, out-of-warranty repair runs $150 to $300 depending on what's wrong.

Keep in mind that if your phone has visible physical damage or water damage, Samsung will likely classify it as out-of-warranty even if you're within the one-year window. They can usually tell from the liquid damage indicators inside the phone.

Use an authorized Samsung repair shop if the quote is too high

Samsung has a network of authorized repair partners across the country. These shops can do the same repairs as Samsung's own service centers, often for less money. To find one near you, go to samsung.com/us/support, select your phone model, and look for "Find a Service Center" or "Repair Options."

Authorized shops will still honor Samsung's warranty terms, so if your phone is under warranty, the repair should be free there too. The main difference is that you're working with a local business instead of Samsung directly, which can mean faster turnaround if the shop has parts in stock.

Before you go to an authorized shop, call ahead and describe the problem. They can tell you whether they stock the part you need and how long the repair typically takes. Some shops can turn around a power issue in a day; others may need to order parts and take a week.

Try basic troubleshooting steps before contacting anyone

Before you call Samsung or visit a repair shop, try these steps. Many phones that seem dead are actually just drained or stuck in a boot loop, and these fixes take five minutes.

Charge the phone for at least 30 minutes. Use the original charger if you have it, or any USB-C charger (for newer Samsung phones) or micro-USB charger (for older models). Plug it in and wait. Some phones take longer than others to show a charging indicator.

Try a force restart. This is different from a normal restart and can fix software problems that prevent the phone from turning on. The method depends on your model: for most recent Samsung phones, hold the Volume Down button and the Power button together for 10 seconds, then release. You should see the Samsung logo. For older models, the combination may be different — search "[your model number] force restart" to find the exact steps.

Check whether the screen is just off. Press the Power button and wait 10 seconds. Some phones have a very dim display or a broken backlight that makes it look like the phone is off when it's actually on. If you see anything on the screen — even a faint outline — the phone may be working.

Contact your carrier if you bought the phone through them

If you purchased your Samsung phone from Verizon, AT&T, T-Mobile, or another carrier, you can also contact them about the problem. They have their own support lines and can sometimes process repairs faster because they have a financial stake in keeping you as a customer.

However, carriers typically handle software issues and account problems, not hardware repairs. For a phone that won't turn on, they'll usually run through the same troubleshooting steps Samsung would, then refer you to Samsung or an authorized repair shop anyway. Call your carrier's support number (it's on your bill or their website) and ask whether they can help before you contact Samsung separately.

One advantage of calling your carrier first: if the phone is still under a carrier protection plan (like AT&T Mobile Protect or Verizon Device Protection), the carrier can tell you immediately whether the repair is covered and may handle the whole process for you.

Understand what happens if repair costs more than replacement

For older Samsung phones, the cost to repair a power issue can sometimes exceed the price of a used replacement phone. When Samsung quotes you a price, compare it to what a used phone of the same model costs on eBay or Facebook Marketplace.

If repair costs $250 and you can buy a used replacement for $150, replacement makes financial sense. Samsung support won't push you toward repair if replacement is cheaper — they'll just give you the quote and let you decide.

If you decide to replace the phone, ask Samsung whether they have a trade-in program. Some Samsung phones have residual value even when broken, and Samsung may credit you $20 to $50 toward a new purchase.

Document the problem for warranty or insurance claims

Before you contact anyone, take a photo or video of what happens when you try to turn the phone on. Show the screen (or lack of one), any error messages, and what you've already tried. This documentation helps if you need to file an insurance claim later or dispute a repair decision.

Write down the date the problem started and what you were doing when it happened. If the phone got wet, dropped, or exposed to extreme heat, mention that — it affects whether the warranty covers the repair, and being honest about it upfront saves time.

Keep your receipt or proof of purchase. You'll need it to prove the phone is still under warranty, and some repair shops won't process a claim without it.

Frequently Asked Questions

How long does Samsung repair usually take?

Samsung's mail-in repair service typically takes 5 to 10 business days from the time they receive the phone. Authorized local repair shops are often faster — sometimes same-day or next-day for common issues like battery replacement. Call ahead to ask about turnaround time for your specific problem.

Can I repair my Samsung phone myself?

You can find replacement parts and repair guides online, but opening the phone yourself will void any remaining warranty. If the phone is out of warranty and you're comfortable with electronics, DIY repair is an option — but if something goes wrong, you've made the problem worse. For most people, paying for professional repair is safer.

What if Samsung says the damage isn't covered by warranty?

You can ask Samsung to explain exactly why they're classifying it as out-of-warranty. If you disagree, ask to speak with a supervisor. You can also get a second opinion from an authorized repair shop — they may assess the damage differently. If you have accidental damage coverage through your carrier or a third-party plan, file a claim with them instead.

Do I need to back up my data before sending the phone in for repair?

If the phone won't turn on, you can't back up the data yourself. Samsung and authorized shops know this and won't erase your phone during repair unless they have to replace the storage component entirely. Ask the repair shop what their policy is on data before you drop it off.

Is it cheaper to buy a new phone or repair the old one?

That depends on the phone's age and the repair cost. A two-year-old phone with a $200 repair might not be worth fixing if a new budget phone costs $300. A newer phone with a $150 battery replacement is usually worth repairing. Samsung support can give you a quote, and then you can decide based on what the phone is worth to you.
