Typical Oppo A77 4G faults
| Fault area | Most common causes and symptoms | What we offer at Fixas |
|---|---|---|
| Battery, 5,000 mAh, BLP923, 33 W | • Capacity drops after about 500 charging cycles and the phone lasts only a few hours. • The battery swells or the back cover lifts because of overheating or deep discharge. | We replace it with an original or OEM battery within 1 to 2 hours. SUPERVOOC fast charging is preserved. |
| Charging port, USB-C | • The phone does not recognise the charger, or charging stops when the cable is moved. • Lint, dirt or traces of corrosion are visible in the port. | We clean the port flex cable ultrasonically or replace the whole connector by micro-soldering. |
| Screen | • The top glass is cracked but the LCD is intact. • The screen flickers, registers phantom touches or does not respond to touch. | If the LCD is intact, we replace the glass layer. If the module is damaged, we replace the whole original screen. |
| Speaker and microphone | • Dust blockage makes sound quiet or muffled. • During calls the other person hears you poorly. | We clean the sound channels or replace the module. If needed, we also replace the gaskets. |
| Overheating | • The phone heats up while gaming or charging. • The device switches off by itself or slows down considerably. | We replace the thermal paste, clean the heat-sink plate and check the mainboard. |
Oppo A77 4G screen replacement
The Oppo A77 4G has a 6.56″ IPS LCD screen with HD+ resolution of 720 × 1612 pixels, about 269 ppi. The screen is covered with Panda MN228 glass. Because of the large screen area, the glass or the touch sensor is usually what gets damaged. If you see no coloured lines, spots or flickering and the picture is displayed normally, we usually replace the glass layer. This way you keep the original screen and pay less. If the LCD or the whole screen module is damaged, we replace the entire screen.
Oppo A77 4G battery replacement
Capacity: 5,000 mAh
Type: Li-Po, not replaceable without special tools
Fast charging: 33 W Pump Express via USB-C
This battery usually lasts 1.5 to 2 days if you make calls, watch videos and use apps and the internet without heavy load. Games, background apps, heat, cold and frequent charging to 100 per cent wear the battery faster.
Common battery faults
Capacity loss
After 12 to 18 months of intensive use, battery capacity often drops to 80 per cent of the original. The phone then discharges faster, even if you use it the same way as before.Swelling
Internal pressure and chemical changes make the battery swell. It presses on the screen, the back cover and the casing. In that case it is better to stop charging the phone and bring it in for a check.Slower fast charging
The battery takes longer to charge or will not enter fast charging mode because it cannot accept the required current. A port fault can cause similar symptoms, so we check both.Sudden shutdowns
When the power supply becomes unstable, the phone switches off even while showing remaining charge. This often happens while taking photos, gaming or using navigation.Overheating
Heavy use or a battery fault raises the temperature. The phone may slow down, drain faster or limit charging.
We replace the battery within 1 to 2 hours, using an original or high-quality equivalent. A replacement phone is available during the repair.
