I also noticed a few things while applying wsd sp.
1. The sp rig has 2 protruding notches at the sides, making it hard for me to push the absorbent pads to absorb any spilling glue. I can only rest it on top of it which means it may not absorb any glue. Thankfully, mine does not have any glue spill.
2. It uses the old design from S8 whereby there is a guide at top. Lay the sp onto it and pull out the guide to lower it and spread the glue.
3. The releasing of glue is not at centre for some reason. Its at the 30% mark of the phone from top. I have applied for s8, s8+, s9, s9+, note 8, note 9, p2xl, p3 and all of them are at the centre if not around 45-55% mark. Had to guide the glue towards the centre.
4. If i lay the sp using the bottom as a base then resting onto the top guide, the overall position of the sp on my s10 seems very low. The camera hole also will not fit well. Once laid down, i had to manually push up the sp to match with the camera hole.
5. Similar to point 4, there is a big gap from top of sp to top of phone if i lay the sp at bottom of rig. Also, there is a small indent at top of sp which should match the bottom part of the speaker at top. That got me thinking if this sp is too small or short, perhaps design taken from older s8 instead?
Hope wsd can solve these issues and provide a refund or replacement set for those bought from qoo10 or shops. It would be bad for their reputation if this is not fixed fully.
