Samsung Galaxy Tab S7 (T870/T875) specifications and common faults

The Samsung Galaxy Tab S7 is one of the most advanced Samsung tablet models released in 2020. It features an 11-inch (27.94 cm) LTPS TFT screen with a resolution of 2560×1600 and a 120 Hz refresh rate, providing a very smooth and vibrant display. The device houses an 8,000 mAh Li-Po battery, offering up to 15–17 hours of browsing the internet or video playback without recharging (depending on usage intensity). Additionally, the Tab S7 supports 45 W fast charging via USB-C, and the Snapdragon 865+ processor ensures powerful performance for many applications and games.

Common faults

• Battery wear – over time, the 8,000 mAh lithium-polymer battery loses capacity (50–70% of the original after 1.5–2 years of intensive use), causing the device to discharge quickly, enter power-saving mode, or fail to turn on at all. The battery may also swell, creating invisible gaps between the screen and the edges of the casing.

• Charging issues – due to constant plugging and unplugging of the USB-C connector, the port may become misaligned, wear out, or become loose, leading to interrupted or very slow charging.

• Screen glass and digitizer (touch) damage – during a fall or impact, the screen can crack or scratch; often, only the glass may be damaged, while the AMOLED or LTPS layer remains intact, requiring only the glass to be replaced (via adhesive). If colored spots, lines, or screen flickering appear, the entire screen usually needs to be replaced.

• Button and sensor issues – eventually, broken volume or power buttons may occur, the POGO pin connector (for connecting S Pen) may not function, or the fingerprint sensor at the bottom of the screen may break.

• Screen (AMOLED/LTPS) and glass replacement

  • If only the glass is cracked and the display and touch layer work without black spots, coloured lines or flickering, we replace just the glass. Keeping the original screen module reduces repair costs.

  • If the screen itself is damaged (appearance of colored spots, flickering, failure of touch zones), we replace it with an original or certified equivalent with the same specifications: 11″ LTPS TFT, 2560×1600 px, 120 Hz, and support for Air Trigger 5.

• Battery replacement (8,000 mAh Li-Po)

  • The original battery has a capacity of 8,000 mAh, 3.85 V lithium-polymer type. Common issues include rapid capacity loss (e.g., after 500+ cycles, the battery retains only ~50% capacity), swelling, overheating while charging, and failure to turn on due to complete discharge.

  • We have original or high-quality third-party replacements with the same specifications, ensuring safe connection to the S7 controllers to avoid problems with fast charging (45 W). On average, battery replacement takes 1–2 hours, and we also perform software diagnostics after replacement – checking if the battery charges correctly and if the capacity is recorded properly.

• Charging port (USB-C) repair and replacement

  • A worn USB-C port or cracked internal flex cable can prevent charging or stop the charging indicator from lighting. We clean or replace the port and replace damaged flex cables.

• Replacement of buttons (volume, power)

  • We replace power and volume button modules with broken mechanisms or poor contact, and repair their connectors.

• Repair of PCM, POGO pin (S Pen) connector

  • If S Pen connectivity features fail or the stylus cannot be charged, we replace the POGO pin connector on the body or logic board.

• Other components: repair or replacement of many small components, such as microphones, speakers, Wi-Fi modules, rear cameras, front cameras, NFC modules, fingerprint sensors on the screen.

Samsung Galaxy Tab S7 screen replacement

If your Tab S7 screen is cracked, broken, or shattered (colors started to “run,” the screen does not display an image, or the touch functionality does not work), we can replace it at our shop with an original module or certified equivalent. The complete screen (LTPS TFT module) with an 11″ resolution (2560 × 1600 px, 120 Hz) and Air Trigger 5 support costs slightly more than just glass replacement. Common cases involve external impacts that cause the laminate to separate, resulting in colored lines or certain areas not responding to touch. If you experience such symptoms, we recommend not delaying – continued use may damage the controllers, and a simple glass issue may require replacing the entire module.

Samsung Galaxy Tab S7 battery replacement

Your Tab S7 originally comes with an 8,000 mAh lithium polymer battery. Electronic device batteries often lose 30–50% of their capacity after 12–18 months of intensive use: the tablet may start to charge quickly, sluggishly, shut down at 20% battery life, or overheat. Another common problem is battery swelling, causing the tablet to become thicker (the entire screen protrudes) or even making it impossible to close the casing. Our technicians safely calibrate and replace the battery with a new original or certified analog – 8,000 mAh, 3.85 V, Li-Po. After the replacement, we check the battery’s charging cycle, test the maximum discharge time, and only then return the device back to the customer.
