Hi. I just bought a Konka SP9 but I am finding it difficult to open the back cover so that I can insert my SIM and memory card. Please help me

To insert the sim card, you need to remove the back cover from the phone and remove the battery. To do this, you just need to find the small cut-out edge on the bottom left corner of the back cover and remove it. You can then remove the battery via the small opening provided above the battery. The sim goes in to the large space provided above the icon that says SIM inside it. That icon always gives you a guide to follow. You need to ensure the sim card's cut out edge is facing to the top left of the phone. The sim size is called standard: which is actually the largest sized sim card available. The sim card should fit perfectly between the cut out areas provided.

Sounds like a bad power supply or another internal issue. Do some research on replacement parts, a power supply & motherboard specifically are good starting points. From there you must decide if it's worth the money and time to fix it, if you do fix it, or maybe it's time to toss it and buy another one- they're unbelievably cheap on Craigslist & FB Marketplace. If you don't deal with either one ask anyone around you that's 30-35 & younger, you'll find someone who can find what you want ASAP. Just a quick example; I picked up a 55" LG LED Smart TV a few weeks ago for $120. I done a quick search and found it, contacted the owner and met up with her & bought it within 1 hour!

top left corner at the front should have a little mark the screen pulls out of the back case unlike most phones
